Intravascular cuff
First Claim
Patent Images
1. An intravascular cuff for receiving a prosthetic, comprising:
- at least one strand braided to form a tubular structure having an extended configuration and a deployed configuration;
whereby in the extended configuration, the tubular structure includes;
a first end and a second end;
a tubular body between the first end and the second end;
a lumen extending through the body;
whereby in the deployed configuration, the first and second ends assume an expanded shape relative to the tubular body; and
whereby upon deployment, an outer ply expands away from an inner ply at the first and second ends to form gaps between the inner and outer plies, thereby giving the first and second ends greater diameters than the tubular body and creating a funnel for guiding a delivery catheter and allowing the outer ply to conform against native tissue while the inner ply creates the funnel.

Abstract
An intravascular cuff acts as a lining between a native vessel and an intravascular prosthetic device. During deployment, the ends of the cuff curl back upon themselves and are capable of trapping native tissue, such as valve leaflet tissue, between the ends. The cuff creates a seal between the vessel and the prosthetic, thereby preventing leakage around the prosthetic. The cuff also traps any embolic material dislodged from the vessel during expansion of the prosthetic.

13. An intravascular cuff comprising:
-
at least one strand braided to form a tubular device having a lumen extending therethrough, the device having elongated, relaxed, and expanded configurations; whereby in the elongated configuration, the tubular device is capable of insertion into a catheter; whereby in the relaxed configuration, the tubular device has a first end and a second end having diameters greater than that of a body portion between the first and second ends; whereby in the expanded configuration, the tubular device has a length shorter than a length of the device in the relaxed configuration; and whereby upon deployment, an outer ply expands away from an inner ply at the first and second ends to form gaps and to give the first end and the second end said diameters greater than that of the body portion between the first and second ends and creating a funnel for guiding a delivery catheter and allowing the outer ply to conform against native tissue while the inner ply creates the funnel. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
