Recognition, context, and distinction
What does it do, and where will I see it?
Use & procedural context
Preserves the initial micropuncture tract after 0.018-inch guidewire access and supports controlled upsizing to a larger guidewire or sheath. Typical contexts include vascular access, tunneled dialysis catheters, ports, fistulograms, and biliary or genitourinary access.
What most clearly distinguishes it from similar devices?
Key distinctions
This sheath is a transitional access component rather than the final working platform, preserving the initial 0.018-inch micropuncture pathway while enabling conversion to a larger guidewire or sheath.
