Claims27
A guide wire sheath for vascular procedures comprising:
- a first end and a second end;
- a feeder portion at the first end;
- a flexible sheath distal to the first end and the feeder portion;
- and
- an exitable lumen in the feeder portion and the flexible sheath,
- wherein the feeder portion has a durometer that is greater than the durometer of the flexible sheath, and wherein the exitable lumen in the feeder portion comprises a non-intersecting cavity.
A guide wire sheath comprising:
- a first end and a second end;
- a feeder portion at the first end;
- a flexible sheath distal to the first end and the feeder portion;
- and
- an exitable lumen in the feeder portion and the flexible sheath,
- wherein the exitable lumen comprises a continuous or non-continuous exit along the length of the exitable lumen in at least a portion of the feeder portion and in at least a portion of the flexible sheath.
A guide wire sheath comprising:
- an exitable lumen for receiving a guide wire wherein the walls of the exitable lumen are configured in a rolled configuration such that when the exitable lumen has received the guide wire the exitable lumen is in an unrolled state, and when the guide wire is not present in the exitable lumen the exitable lumen rolls back to a substantially collapsed state when compared to the exitable lumen containing the guide wire.
