Blood flow conduit delivery system and method of use
First Claim
1. A method of delivering a conduit into a portion of a patient'"'"'s body having a first passageway and a second passageway joined generally at an angle, comprising:
- providing a delivery catheter having a proximal end and a distal end and a lumen extending therethrough;
placing the delivery catheter in the patient such that the proximal end extends outside of the patient and the distal end is located substantially adjacent a location where the first passageway and the second passageway are joined;
providing a conduit in the lumen of the delivery catheter, the conduit having a proximal section and a distal section;
advancing the proximal section of the conduit out of the lumen at the distal end of the delivery catheter into the first passageway; and
advancing the distal section of the conduit into the second passageway, wherein the first passageway is a myocardial passageway formed through the myocardium of the heart between the left ventricle and a coronary artery.

Abstract
Described herein is a catheter system for delivering an L-shaped conduit into the body of a patient between the left ventricle and coronary artery. A shunt preferably made of semirigid material is inserted into the lumen of a delivery catheter. The delivery catheter is advanced within the patient until its distal end is located adjacent to the desired insertion site, which is preferably the junction between a coronary artery and passageway formed in the myocardium between the left ventricle and coronary artery. A proximal section of the shunt is first advanced out of the delivery catheter into the myocardial passageway. A distal section of the shunt is advanced into the coronary artery, preferably by advancing the distal section of the shunt into the myocardial passageway and then pulling the distal section back into the coronary artery, or by pushing the distal section of the shunt in a folded configuration out of the delivery catheter into the coronary artery. In one embodiment, the shunt is made of a collapsible material for insertion into the delivery catheter, the shunt expanding upon removal from the delivery catheter.
