Apparatus and methods for alignment and deployment of intracardiac devices
First Claim
1. An apparatus, comprising:
- a handle assembly;
a tube assembly including an outer tube member defining a lumen and a coupling member coupled to a distal end portion of the outer tube member;
a needle assembly configured to be received through the lumen of the outer tube member, the needle assembly including an elongate needle having a distal tip configured to be inserted through the epicardial surface of a heart and extend within the left ventricle of the heart; and
an imaging probe coupled to the coupling member, the imaging probe including a cable and an imaging element disposed at, and directly coupled to, a distal end portion of the cable, the imaging probe configured to provide image data associated with a location of a commissural-commissural (C-C) plane and a location of the anterior-posterior (A-P) plane of the mitral valve and the annular region of the heart such that a prosthetic mitral valve can be deployed and positioned within the heart based at least in part on the C-C plane and the A-P plane,wherein the cable includes a proximal end portion coupled to the handle assembly and an intermediate portion extending between the proximal end portion and the distal end portion, the intermediate portion of the cable being positioned within the outer tube member, the distal end portion of the cable exiting a distal end of the outer tube member so that the distal end portion of the cable of the imaging probe forms a targeting loop configured to contact a portion of the epicardial surface to help stabilize the needle assembly when inserted into the heart, the targeting loop configured to define an aperture through which the elongate needle is configured to travel.

Abstract
Apparatus and methods are described herein for use in the alignment and deployment of a prosthetic heart valve, such as a mitral valve. In some embodiments, an apparatus includes a tube assembly and a needle assembly configured to be received through a lumen of an outer tube member of the tube assembly. The needle assembly includes an elongate needle having a distal tip configured to be inserted through the epicardial surface of a heart. An imaging probe is coupled to a coupling member and includes an imaging element. The imaging probe is configured to provide image data associated with a location of a commissural-commissural (C-C) plane and a location of the anterior-posterior (A-P) plane of the mitral valve and the annular region of the heart such that a prosthetic mitral valve can be positioned within the heart based at least in part on the C-C plane and the A-P plane.
