Abstract
The present disclosure pertains to new methods of making an introducer sheath with an inner liner for percutaneous insertion of a medical device into a patient. The present disclosure also discloses embodiments of catheter-based prosthetic heart valves, including, prosthetic heart valves having sealing members configured to seal the interface between the prosthetic valve and the surrounding tissue of the native annulus in which the prosthetic valve is implanted.
Claims18
A method of making an introducer sheath with an inner liner for percutaneous insertion of a medical device into a patient, comprising:
- inserting a metal sleeve into a mold;
- inserting a polymer tube comprising a closed end and an open end into the metal sleeve;
- pressurizing and heating the polymer tube to cause the polymer tube to expand against an inner surface of the metal sleeve so as to form the inner liner of the sheath.
A method of making an introducer sheath configured for percutaneous insertion of a prosthetic heart valve through a blood vessel of the patient, comprising:
- inserting a metal sleeve into a mold;
- inserting a polymer tube comprising a closed end and an open end into the metal sleeve;
- pressurizing and heating the polymer tube to cause the polymer tube to expand against an inner surface of the metal sleeve so as to form the inner liner of the sheath, wherein pressurizing the polymer tube comprises injecting compressed gas into the polymer tube.
