Low profile heart valve delivery system and method
First Claim
Patent Images
1. A percutaneous heart valve delivery system having a first configuration and a second configuration, the system comprising:
- a sheath;
a stent having a proximal end, a distal end, and a lateral side;
a replacement valve having a proximal end, a distal end, and a lateral side;
at least one suture line extending through the lateral side of the replacement valve, the lateral side of the stent, and between the stent and replacement valve;
wherein, when the system is in the first configuration, the stent and replacement valve are disposed within the sheath and the distal end of the replacement valve is proximal to the proximal end of the stent; and
when the system is in the second configuration, the distal end of the replacement valve is distal to the proximal end of the stent;
wherein pulling proximally on the at least one suture line shifts the system from the first configuration to the second configuration by translating the replacement valve distally toward the stent.

Abstract
A heart valve delivery system includes a low-profile catheter having an outer sheath, the outer sheath having therein a stent and a replacement heart valve. In an unemployed configuration, the stent is located distally to the replacement heart valve. Upon deployment, however, the stent and replacement heart valve are expanded and the replacement heart valve is situated within the stent.

8. A method of deploying a replacement heart valve comprising:
- providing a percutaneous heart valve delivery system comprising;
a sheath;
a stent having a lateral side;
a replacement heart valve having a lateral side; and
at least one suture line routed through the lateral side of the replacement heart valve and the lateral side of the stent;
inserting the heart valve delivery system through a body lumen;
deploying the stent from the sheath;
expanding the stent;
deploying the replacement heart valve from the sheath; and
pulling proximally on the at least one suture line to radially expand the replacement heart valve and move distally the replacement heart valve into contact with the stent.
