Abstract
This invention discloses a medical catheter and methods for removing a defective valve from a patient endoluminally. The method may comprise inserting a medical catheter endoluminally to a site of the defective valve; deploying a coupling mechanism of said medical catheter to stabilize and immobilize a free edge of at least one valve leaflet; deploying a cutting mechanism of said medical catheter to cut a valve base of said defective valve; and removing said defective valve from the patient.
Claims22
A method for removing a defective valve from a patient, the method comprising:
- immobilizing at least a valve leaflet of said defective valve;
- separating a valve base from a valve root of the defective valve, wherein the valve base comprises at least one commissure;
- and
- removing said defective valve.
A medical catheter for removing a defective valve from a patient comprising:
- an elongate catheter shaft having a catheter distal end, a catheter distal section, a catheter proximal end, and at least a lumen between said catheter distal end and said catheter proximal end;
- a deployable inner catheter located within one of said at least a lumen;
- a coupling mechanism located at the catheter distal section configured to grip and immobilize a free edge of at least one valve leaflet of the defective valve;
- and
- a cutting mechanism mounted at a distal end of the deployable inner catheter, wherein the cutting mechanism is configured to cut and separate a valve base of said defective valve from a valve root of said defective valve.
A method for removing a defective valve from a patient endoluminally, the method comprising:
- (a) inserting a medical catheter endoluminally to a site of the defective valve;
- (b) deploying a coupling mechanism of said medical catheter to stabilize and immobilize a free edge of at least one valve leaflet;
- (c) deploying a cutting mechanism of said medical catheter to cut a valve base of said defective valve;
- and
- (d) removing said defective valve from the patient.
