Transapical delivery system with ventruculo-arterial overlfow bypass
First Claim
1. A method for implanting a prosthetic device in a patient, the method comprising:
- transmyocardially advancing a trocar tube housing a prosthesis into a left ventricle of a subject, wherein the prosthesis restricts drainage of blood from the left ventricle into an opening at a distal end of the trocar tube when the prosthesis is housed in the trocar tube;
advancing the prosthesis through a valve of the patient, wherein advancing the prosthesis frees the opening in the distal end of tube, thereby allowing blood from the left ventricle to drain into an interior of the trocar tube; and
during the advancing of the prosthesis, providing a blood flow bypass path from the left ventricle of the patient, into the opening at the distal end of the trocar tube, through at least a portion of the interior of the trocar tube, and to an extracardiac arterial site downstream from the valve.

Abstract
Apparatus is provided for implanting a prosthetic device (108) in a patient, the apparatus includes a trocar tube (101), a first portion of which is configured to be placed in a left ventricle (12) of the patient during a procedure for implantation of the prosthetic device (108), and a second portion of which is configured to be placed in an extracardiac location during the procedure. The first portion is shaped so as to define at least one opening to an interior thereof. One or more flexible bypass tubes (103, 104, 106), each of which is coupled to the second portion, and each of which is configured to be coupled to at least one artery (20, 21, 30) of the patient, so as to create a blood flow bypass path during the procedure, from the left ventricle (12), via the opening and the bypass tubes (103, 105, 106), to the at least one artery (20, 21, 30). Other embodiments are also described.
