Sequential heart valve leaflet repair device and method of use
First Claim
1. An apparatus for treating tissue within a patient'"'"'s body, the apparatus comprising:
- a generally elongated catheter having a distal end portion and a proximal end portion;
a vacuum port assembly positioned on the catheter distal end portion, the vacuum port assembly configured to apply a vacuum in order to releasably grasp tissue;
a vacuum control apparatus configured to control the application of vacuum to the vacuum port assembly;
a first suture deploying apparatus configured to deploy suture through tissue, the first suture deploying apparatus positioned on the catheter distal end;
a second suture deploying apparatus configured to deploy suture through tissue, the second suture deploying apparatus positioned on the catheter distal end;
a suture deployment actuator apparatus configured to independently actuate the first suture deploying apparatus and the second suture deploying apparatus, wherein the first suture deploying apparatus can be actuated to deploy suture without actuation of the second suture deploying apparatus.

Abstract
A heart valve and tissue repair device for independently, selectively and sequentially grasping heart valve leaflets and independently, selectively and sequentially applying one or more fasteners thereto is disclosed. The device includes a leaflet engaging tip having one or more graspers capable of individually and sequentially grasping leaflets, and one or more deployable fasteners capable of fastening the leaflets. An actuation system for the device individually and selectively controls the graspers and deploys the one or more fasteners. Vacuum pressure from an external vacuum source can be used to grasp the leaflets via a selector system that controls the actuation system so as to individually and sequentially apply vacuum force to the graspers.
