First Claim
Patent Images
1. An apparatus for local delivery of a drug to internal body tissue of a patient comprising:
- (a) a catheter having drug delivery means;
(b) a plurality of electrodes, at least one of said electrodes being operably connected to the catheter;
(c) drug delivery current/voltage means electrically connected to at least two of said electrodes for transport of said drug from said drug delivery means to said internal body tissue; and
(d) pacing means electrically connected to at least two of said electrodes, the pacing means being configured to generate a pulse for stimulating the patient'"'"'s heart to begin the refactory period of the heart beat, the drug-delivery current/voltage means being synchronized with the pacing means to transport at least a portion of said drug after generation of said pulse.
