Bone density ultrasound heel is a **quantitative ultrasound (QUS)** medical device designed to assess bone-related parameters at the **calcaneus (heel bone)**. It is used in many clinical and community settings to support **bone health risk assessment**—often where access to dual-energy X-ray absorptiometry (**DXA**, also written DEXA) is limited, or where a fast, portable, non-ionizing test is operationally helpful.

A **Skeletal traction pin set** is a small but high-impact piece of orthopedic **medical equipment** used to apply traction directly to bone using a percutaneous (through-the-skin) pin or wire. Unlike skin traction (which pulls through bandages and soft tissue), skeletal traction transfers force to the skeleton, which can help maintain limb length, alignment, and comfort while a patient awaits definitive treatment or ongoing management.

Orthopedic traction frame is a mechanical medical device used to apply a controlled pulling force (traction) to an injured limb or body segment to help maintain alignment, reduce muscle spasm, and support stabilization during assessment, transport, inpatient care, or selected surgical workflows. In many hospitals it is part of essential orthopedic hospital equipment because it can be deployed quickly, does not require complex electronics, and can be adapted to different patient sizes and clinical settings.

Cast saw is a powered medical device used to cut and remove rigid orthopedic casts and some types of splints. It is common hospital equipment in emergency departments (EDs), orthopedic clinics, plaster rooms, and pediatric services—anywhere immobilization is applied and later needs safe, efficient removal.

Radiofrequency ablation catheter is a sterile, flexible clinical device used to deliver radiofrequency (RF) electrical energy to targeted tissue inside the body. When used with an RF generator and appropriate monitoring, it creates controlled thermal injury (an “ablation lesion”) intended to modify tissue function—most commonly in cardiac electrophysiology (EP) procedures, but also in selected vascular and endoluminal applications depending on the model and specialty.

An **EP study recording system** is specialized medical equipment used in cardiac electrophysiology (EP) procedures to **acquire, display, annotate, and store electrical signals from the heart**. In practical terms, it is the “signal hub” of an EP lab: it brings together surface electrocardiogram (ECG) leads, intracardiac catheter signals (electrograms), pacing markers, and often other physiologic inputs so the clinical team can make real-time decisions and document the procedure.

Temporary transvenous pacing wire is a catheter-based **temporary cardiac pacing lead** placed through a vein and positioned inside the heart to deliver electrical impulses when the patient’s intrinsic heart rate or conduction system is unreliable. It is typically connected to an **external pulse generator** (a reusable pacing box) that allows clinicians to set pacing mode, rate, and output.

A **Vascular closure device (VCD)** is a clinical device used to help achieve hemostasis (bleeding control) at an arterial or venous access site after a catheter-based procedure. It is most commonly associated with percutaneous (through-the-skin) access in interventional cardiology and interventional radiology, where catheters and sheaths are inserted into blood vessels to diagnose or treat disease.

Contrast injector cath lab refers to a programmable “power injector” system used in a cardiac catheterization laboratory (cath lab) to deliver radiographic contrast media (commonly iodinated contrast) and, in many setups, a saline flush at controlled flow rates, volumes, and pressure limits. The goal is to achieve consistent vessel opacification during angiography and related interventional procedures while supporting standardized workflows and documentation.

A Thrombectomy device is a catheter-based medical device used to physically remove a blood clot (thrombus) from a blood vessel. It is most commonly used in time-sensitive, high-acuity settings—such as acute ischemic stroke, pulmonary embolism (PE), acute limb ischemia, and selected venous thromboses—where restoring blood flow can be clinically urgent.

A Rotational atherectomy system is a catheter-based medical device used in interventional cardiology to modify severely calcified atherosclerotic plaque—most commonly in the coronary arteries—during percutaneous coronary intervention (PCI). In plain language, it uses a high-speed rotating burr to “sand” hard calcium so balloons and stents can be delivered and expanded more predictably.

Guidewire coronary is a thin, steerable wire used inside the coronary arteries (the blood vessels that supply the heart muscle) during catheter-based cardiac procedures. In many hospitals, it is an everyday *medical device* in the cardiac catheterization laboratory (“cath lab”) and hybrid operating room, most commonly supporting percutaneous coronary intervention (PCI), also called coronary angioplasty with or without stent placement.

Coronary stent system refers to an implantable vascular scaffold (the stent) and its delivery mechanism (typically a catheter-based system) used during percutaneous coronary intervention (PCI) to help restore and maintain blood flow through narrowed coronary arteries. In day-to-day hospital operations, it sits at the center of catheterization laboratory (“cath lab”) workflows—linking clinical decision-making, radiation-based imaging, sterile technique, inventory control, and post-procedure monitoring.

Angioplasty balloon catheter is a sterile, single-use clinical device designed to widen a narrowed blood vessel during an endovascular procedure (angioplasty). It is a core piece of hospital equipment in cardiac catheterization (cath) labs, interventional radiology (IR) suites, and vascular procedure rooms, where fast, controlled vessel dilation can be essential to restoring blood flow and enabling other therapies (such as stent placement).

Fractional flow reserve FFR system is an invasive coronary physiology medical device used in cardiac catheterization laboratories to evaluate whether a coronary artery narrowing (stenosis) is likely to limit blood flow enough to matter clinically. It complements coronary angiography by adding a functional (physiology-based) assessment rather than relying on anatomy alone.

Optical coherence tomography intravascular OCT is a catheter-based imaging medical device used inside blood vessels to create high-resolution, cross-sectional views of the vessel lumen and the structures near the inner vessel wall. It is most commonly used in cardiac catheterization laboratories (cath labs) during coronary angiography and percutaneous coronary intervention (PCI), where imaging detail can influence procedural planning and immediate quality checks.

Intravascular ultrasound IVUS (often shortened to IVUS) is a catheter-based imaging technique that produces ultrasound pictures from inside a blood vessel. Instead of viewing arteries only as a “silhouette” with angiography, IVUS can help clinicians see a cross-sectional view of the vessel lumen (the channel blood flows through), the vessel wall, and patterns of plaque.

A Hemodynamic recording system is specialized medical equipment used to capture, display, measure, and store cardiovascular “hemodynamic” signals—most commonly invasive blood pressure waveforms and electrocardiography (ECG)—during procedures such as cardiac catheterization and other interventional cases. In simple terms, it helps teams see what the heart and vessels are doing in real time, document what happened during key moments, and produce an auditable record for clinical review and reporting.

A **Cardiac catheterization lab system** is a specialized suite of **hospital equipment** used to perform catheter-based diagnostic and interventional procedures on the heart and major blood vessels. It combines real-time X‑ray imaging (fluoroscopy and cineangiography), patient support (table and positioning), physiologic monitoring (electrocardiogram and pressures), and data recording so clinicians can see anatomy, measure hemodynamics, and treat selected conditions through minimally invasive access.

An **Ophthalmic ultrasound biometer** is a specialized medical device used to measure key eye dimensions—most importantly **axial length** (front-to-back length of the eye)—using ultrasound. These measurements are central to planning many ophthalmic procedures, especially **cataract surgery**, where accurate sizing helps clinicians select an appropriate **intraocular lens (IOL)** power.

Lens implant intraocular lens is an implantable optical medical device placed inside the eye to replace or augment the focusing function of the natural crystalline lens. It is most commonly associated with cataract surgery, one of the highest-volume procedures performed in many hospitals and ambulatory surgical centers, but it can also be used in selected refractive and reconstructive scenarios.

An **Ophthalmic instrument tray** is a curated, organized set of ophthalmology-specific surgical instruments and accessories presented together for safe, efficient use during eye procedures. In practical terms, it is both a **clinical device workflow tool** (standardizing what the team needs and where it sits on the sterile field) and a key element of the hospital’s **sterile processing and supply chain system**.

Anterior chamber maintainer is a small but high-impact ophthalmic medical device used during intraocular (inside-the-eye) surgery to keep the anterior chamber (AC) formed and stable. In plain language, it continuously delivers sterile irrigating fluid into the front chamber of the eye so the surgeon can work in a controlled space without the chamber collapsing.

An Ophthalmic cautery unit is a piece of medical equipment used to deliver controlled thermal energy to small areas of tissue—most commonly to achieve hemostasis (control bleeding) during eye and periocular (around-the-eye) procedures. In ophthalmology, the surgical field is small, lighting is intense, and tissues are delicate; even a small amount of bleeding can quickly obscure the view under loupes or an operating microscope and slow down safe workflow.

Microkeratome is a precision ophthalmic surgical medical device designed to create a controlled, lamellar (layer-by-layer) cut in the cornea. In routine practice it is best known for forming a corneal flap during LASIK (laser-assisted in situ keratomileusis), but it is also used in selected corneal transplant workflows and donor tissue preparation in some settings.

Corneal trephine is a surgical cutting instrument used to create a precise, circular incision in the cornea. In practical terms, it helps ophthalmic teams “punch” or trephinate a round corneal button (tissue disc) or make a controlled circular cut/mark that guides corneal surgery. Although it is a relatively small piece of hospital equipment, it can have an outsized impact on surgical accuracy, tissue utilization, and downstream outcomes such as wound configuration and graft fit.

Ophthalmic viscoelastic injector is a sterile medical device used to deliver an ophthalmic viscoelastic device (OVD) into the eye during surgery or selected procedures. OVDs are gel-like solutions designed to help maintain space, stabilize tissues, and support visualization—most commonly in anterior segment surgery such as cataract operations.

An **IOL injector** is a sterile medical device used to deliver an **intraocular lens (IOL)** into the eye, most commonly during cataract surgery after the cloudy natural lens has been removed. Although it can look simple—a handpiece with a cartridge and a plunger—its performance can influence incision integrity, lens handling, surgical flow, and the risk profile of the procedure.

Ocular speculum is a small but essential medical device used to gently hold the eyelids apart so clinicians can examine or operate on the eye without needing continuous manual retraction. You will see it in outpatient eye clinics, procedure rooms (for injections and minor procedures), emergency settings, and operating theatres for ophthalmic surgery.

An Ophthalmic surgical microscope is a specialized surgical microscope designed to provide high-magnification, high-illumination, stereoscopic (3D) visualization of delicate eye structures during ophthalmic procedures. In modern operating rooms (ORs), it is core hospital equipment for anterior segment surgery (such as cataract and corneal procedures) and is also widely used in vitreoretinal and glaucoma surgery when paired with appropriate visualization accessories.
