Intracardiac cell delivery and cell transplantation
First Claim
1. A method for inducing angiogenesis or myogenesis in a heart of a patient comprising the steps of:
- providing a system for intracardiac drug administration comprising a catheter, said catheter having at least one position sensor which generates signals responsive to an applied field for determining the position and orientation of said catheter, said signals being used to generate position and orientation coordinates, and a drug delivery device for delivering said cell, the system also comprising control circuitry for determining position and orientation coordinates of a distal end of said catheter and for generating a viability map of said heart comprising a site suitable for targeted therapy by said catheter;
generating the viability map of the heart;
identifying said site suitable for targeted therapy on said viability map;
inserting said catheter into a chamber of said heart at said site;
delivering said cell to said site with said drug delivery device based on position and orientation coordinates in response to said signals from said position sensor, and inducing angiogenesis or myogenesis in said site of said heart from said delivered cell.

Abstract
A method for delivering a cell to a heart of a patient comprises the steps of providing an apparatus for intracardiac drug administration comprising a catheter wherein the catheter has at least one position sensor which generates signals responsive to the position of a catheter and a drug delivery device for delivering the cell. The catheter is inserted into a chamber of the heart at a site and the cell is delivered to the site with the drug delivery device in response to the signals from the position sensor. Typical cells useful for delivery are either myoblasts or myocytes. These cells may be utilized as either an expression vector for promoting angiogenesis or for cell transplantation and fusion through myogenesis.
