Peripheral vascular devices  are used to prevent and treat various peripheral arterial diseases affecting arteries outside the heart. These conditions include peripheral artery disease, deep vein thrombosis and pulmonary embolism. Some common PVD include angioplasty balloons, stents, catheter-guidewires, bypass grafts and plaque removal devices.

Peripheral Vascular Angioplasty Balloons and Stents

Peripheral angioplasty balloons are used to clear blockages or treat narrowings in peripheral arteries outside the heart. During an angioplasty procedure, a thin catheter is inserted into the artery and navigated to the site of narrowing, where the deflated balloon is passed through. The balloon is then inflated to widen the artery and improve blood flow. Peripheral vascular stents may also be used to prop open arteries after angioplasty and prevent renarrowing. Self-expanding and balloon-expandable stents are commonly used for peripheral procedures involving the arteries in the legs.

Peripheral Vascular Catheters and Guidewires

Catheters and guidewires are core components of an endovascular intervention to access and cross arterial lesions. Vascular catheters come in different shapes and sizes depending on the artery being accessed. Guidewires are long, thin wires that are used to direct catheters and devices like balloons or stents to blockages in blood vessels. Hydrophilic-coated and tapered-tip guidewires facilitate smooth insertion and navigation of catheters through complex arterial anatomy. Premium guidewires coated with platinum or platinum-tungsten alloys also provide greater torquability and pushability.

Peripheral Bypass Grafts

Peripheral bypass grafting is performed to create an alternative path for blood when arteries are severely blocked. Bypass grafts used include autologous veins from the leg (saphenous vein graft) or synthetic vascular grafts made of polyester or expanded polytetrafluoroethylene (ePTFE). Selection depends on the site and extent of arterial narrowing. Synthetic grafts are favored when suitable veins are lacking. Bypass grafting aims to restore arterial blood flow and reduce risks of limb amputation from peripheral vascular diseases.

Plaque Removal Devices

Various mechanical thrombectomy and atherectomy devices help remove buildup of plaque or blood clots from obstructed peripheral arteries. These include rotational atherectomy systems, directional atherectomy catheters and excisional thrombectomy devices. Rotational atherectomy drills through hard plaque using a diamond-coated burr, while directional atherectomy cuts and traps plaque against a protective blade. Excisional thrombectomy devices employ a cutter, laser or vacuum to fragment and extract thrombi from vessels. Plaque removal facilitates successful angioplasty or reopening of vessels.

Market Drivers and Future Trends

The  peripheral vascular devices  size was valued at billion in 2019 and is predicted to experience robust expansion at a CAGR of between 2020 to 2025. Key factors fueling market growth include rising global prevalence of peripheral artery diseases, increasing life expectancy, better reimbursement coverage and technological advancements.

In Summary, other likely market trends include integration of drug-eluting and bioabsorbable stents, adoption of advanced imaging methods, development of products for underserved therapies and expansion into emerging countries. Industry players are anticipated to launch novel catheters, guidewires, thrombectomy systems and next-gen endovascular grafts to tap long-term opportunities in this space.
