Abstract
An apparatus for intracardiac drug administration of a therapeutic drug comprises a catheter having a distal end and a drug delivery device which is driveable from the distal end. The drug delivery device includes a needle and a spring-loaded mechanism operatively connected to the needle. The spring-loaded mechanism drives the needle out of the distal end of the catheter upon administering of the therapeutic drug. The spring-loaded mechanism returns the needle within the distal end of the catheter after the administering of the therapeutic drug.
