Steerable Catheter and Dilator and System and Method for Implanting a Heart Implant
First Claim
1. A catheter configured to extend through a transseptal puncture site, a left atrium, and into a left ventricle, said catheter comprising:
- a shaft defining at least one lumen configured to receive at least one of an implant and/or a dilator;
a first steerable actuator coupled to said shaft at a position on said shaft substantially corresponding to said transseptal puncture site when a distal end of said shaft is disposed within said left ventricle; and
a handle assembly coupled to a proximal end of said shaft, said handle assembly comprising a first actuator coupled to said first steerable actuator, said first actuator configured to apply a force to said first steerable actuator to deflect said shaft about a region proximate to said first steerable actuator.

Abstract
A catheter according to one embodiment may be configured to extend through a transseptal puncture site, a left atrium, and into a left ventricle. The catheter may comprise a shaft defining at least one lumen configured to receive at least one of an implant and/or a dilator, a first steerable actuator coupled to the shaft at a position on the shaft substantially corresponding to the annulus of the mitral valve when the distal end of the shaft is disposed within the left ventricle, and a handle assembly coupled to a proximal end of the shaft. The handle assembly may comprise a first actuator coupled to the first steerable actuator. The first actuator may be configured to apply a force to the first steerable actuator to deflect the shaft about a region proximate to the first steerable actuator.
