Abstract
A modular drug delivery system for use by cardiothoracic surgeons and interventional cardiologists for delivery of molecular and cellular therapies that target genes, molecules and peptides. The regulated drug delivery devices comprise a modular mechanically actuated drug delivery module (DDM) that can be attached to either a surgical viewing endoscope hand-piece or specialized catheter for interventional procedures. The DDM provides metering of drugs to treatment sites and allows for quick interchangeability with other component parts such as a viewing scope end portion for MIS or other surgical procedures or a flexible catheter shaft for percutaneous procedures.
Claims9
A drug delivery device for medicating internal tissue during minimally invasive surgery and/or other surgical procedures, the device comprising:
- (a) a drug delivery needle having a piercing tip and attached to a distal end of a drug conduit, the drug conduit also having a proximal end;
- and
- (b) a detachable drug delivery module for metering the drug, the detachable drug delivery module including:
- (i) a housing having a quick-disconnect interface for coupling to said drug conduit;
- (ii) at least one drug reservoir communicating with the drug conduit, the at least one reservoir mounted within the housing;
- and
- (iii) an actuating means for (1) advancing the drug delivery needle, (2) displacing drug from the at least one reservoir through the drug delivery needle via the drug conduit, and (3) retracting the drug delivery needle, the actuating means also mounted within the housing;
- (c) a body member at the proximal end of said drug conduit, said body member adapted for connecting a visualization scope thereto, the body member being attached to the housing;
- and
- (d) an introducer having a length sufficient to reach a treatment site at target tissue, the introducer defining a working channel wherein the advanceable drug delivery needle with attached drug conduit is disposed therein, the piercing tip of the drug delivery needle being egressable at the introducer's distal end.
A drug delivery device for medicating internal body tissue during catheter and/or other percutaneous procedures, the device comprising:
- (a) a drug delivery needle having a piercing tip, said needle being attached to a distal end of a drug conduit, the drug conduit also having a proximal end;
- and
- (b) a detachable drug delivery module for metering the drug, the detachable drug delivery module including:
- (i) a housing having a quick-disconnect interface for coupling to said drug conduit;
- (ii) at least one drug reservoir communicating with the drug conduit, the at least one reservoir mounted within the housing;
- and
- (iii) actuating means for (1) advancing the drug delivery needle, (2) displacing drug from the at least one reservoir through the drug delivery needle via the drug conduit, and (3) retracting the drug delivery needle, the actuating means mounted within the housing;
- (c) an introducer having a length sufficient to reach a treatment site at target tissue, the introducer being attached to the quick-disconnect interface, the introducer defining at least one working channel in which said drug delivery needle and said drug conduit are disposed, the piercing tip of the drug delivery needle being egressable at the introducer's distal end.
A detachable drug delivery module kit for visualizing and medicating internal body tissue during MIS and other surgical procedures and for catheter and/or percutaneous procedures, the kit comprising:
- (a) a drug delivery needle having a piercing tip, said needle being attached to a distal end of a drug conduit, the drug conduit also having a proximal end;
- and
- (b) a detachable drug delivery module for metering the drug, the detachable drug delivery module including:
- (i) a housing having a quick-disconnect interface for coupling to said drug conduit;
- (ii) at least one drug reservoir communicating with the drug conduit, the at least one reservoir mounted within the housing;
- and
- (iii) actuating means for (1) advancing the drug delivery needle, (2) displacing drug from the at least one reservoir through the drum delivery needle via the drug conduit, and (3) retracting the drug delivery needle, the actuating means also mounted within the housing;
- (c) a visualization scope having a body member for attachment to said housing, said visualization scope including a viewing means for optical viewing at the distal end of the drug conduit;
- (d) an endoscope-type introducer having a length sufficient to reach a treatment site, the endoscope-type introducer defining a working channel in which said drug delivery needle and said drug conduit are disposed, the piercing tip of the drug delivery needle being egressable at the endoscope-type introducer's distal end;
- and
- (e) a catheter introducer having a length sufficient to reach a treatment site, the catheter introducer defining a working channel in which said drug delivery needle and said drug conduit are disposed, the piercing tip of the drug delivery needle being egressable at the catheter introducer's distal end.
