Title:
TELESCOPING CATHETER DELIVERY SYSTEM FOR LEFT HEART ENDOCARDIAL DEVICE PLACEMENT
Document Type and Number:
WIPO Patent Application WO/2012/058586
Kind Code:
A3
Abstract:
A transseptal catheter delivery system includes an elongate first tubular member and an elongate second tubular member receivable within the first tubular member. The first tubular member includes an adjustable portion adjacent a distal end. The second tubular member is adapted to receive an instrument to be placed in the left ventricle, and includes a curved portion adjacent its distal end in a relaxed state. The adjustable portion is deflectable toward the atrial septum to guide a puncturing tool and/or guide insertion of the second tubular member through a septal puncture into the left atrium. Within the left atrium, the curved portion is oriented toward the left ventricle to guide insertion of a guide wire, and subsequently the second tubular member, into the left ventricle. Methods of transvenously accessing a left ventricle are also provided.
