Vascular access and closure technologies — the introducer sheaths, guidewires, catheters, and percutaneous closure systems enabling efficient and safe peripheral vascular interventional access — represent the essential enabling infrastructure market for the peripheral intervention ecosystem, with the Peripheral Intervention Market reflecting access technology as a foundational peripheral intervention market component.

Percutaneous vascular closure devices — the Proglide (Abbott), MANTA (Teleflex), Starclose SE (Abbott), Angio-Seal (Terumo), and Mynx (Cordis) percutaneous closure systems enabling arteriotomy closure without surgical cutdown — represent the access management market that has transformed peripheral intervention from predominantly surgical access toward percutaneous approaches. MANTA's dedicated large-bore closure capability (fifteen to twenty-five French) enabling percutaneous EVAR and TAVR access has been particularly transformative for complex aortic and structural heart procedures.

Radial artery access for peripheral intervention — the adoption of transradial access for peripheral angiography and selected peripheral interventions providing reduced access site complications compared to femoral access — represents the transradial revolution extending from coronary intervention into peripheral vascular procedures. Radial access for iliac and aortic diagnostic angiography reduces access site complications and enables immediate ambulation.

Long sheath and guide catheter systems — the specialized long sheath systems (Ansel, Flexor) providing stable access for complex peripheral interventions — represent the device infrastructure enabling technically challenging peripheral procedures. Forty-five to ninety-centimeter access sheaths providing stable guide catheter position deep in the vascular anatomy enable complex below-knee and distal tibial interventions that standard femoral sheath positioning cannot adequately support.

Do you think the adoption of radial artery access for peripheral angiography will reach the prevalence seen in coronary angiography, or do peripheral procedural requirements favor femoral access for most interventional cases?

FAQ

What are percutaneous vascular closure devices and how do they work? Vascular closure devices (VCDs) close the arterial access site percutaneously after catheterization, eliminating the need for sustained manual compression; major types: suture-based (ProGlide/Proglide Plus — Abbott, deploys sutures pre-loaded on the device to close the arteriotomy by knotting sutures), plug-based (Angioseal — Terumo, deploys a collagen sponge plug anchored by a polymer foot inside the vessel), clip-based (StarClose SE — Abbott, deploys a nitinol clip on the vessel wall), and VBAS (Chitosan-based patches); large-bore closure for TAVR/EVAR: MANTA (Teleflex) dedicated for fourteen to twenty-five French sheaths using a collagen plug with suture; VCDs reduce time-to-hemostasis, enable earlier ambulation, reduce access site hematoma versus manual compression; learning curve required to avoid vessel occlusion or bleeding complications.

What guidewires are used in peripheral vascular intervention? Peripheral guidewires vary by application: standard working wires (0.035-inch diameter, Bentson, Amplatz Super Stiff) for primary access and device tracking; hydrophilic-coated wires (Terumo Glidewire, standard and angled, and stiff hydrophilic wires for occlusion crossing) for navigating tortuous vessels and crossing lesions; support wires (Amplatz Super Stiff, Lunderquist) for catheter and device exchanges requiring strong support; micro-guidewires (0.014-inch, 0.018-inch) for below-knee interventions (coronary-adapted wires for tibial arteries); specialty wires for CTO crossing (Outback re-entry catheter with specialty wires for parallel wire technique); proper wire selection critical for efficient and safe peripheral intervention navigation.
