Abstract:
1. A surgical device for ablating a channel and delivering at least one therapeutic agent into a desired region of tissue, comprising: (a) a first elongated multi-lumen tube; (b) an elongated tissue ablating assembly supported in a first lumen of the first multi-lumen tube, said ablating assembly extending from a source of laser energy into an ablating tip adapted for ablating a channel into the tissue; (c) a therapeutic agent delivery assembly supported in a second lumen of the multi-lumen tube, said therapeutic agent delivery assembly having a proximal end adapted for receiving a source of the therapeutic agent and extending distally through the second lumen to a delivery tip, the delivery assembly adapted for receiving the therapeutic agent and providing a conduit to the delivery tip wherein the ablating tip and therapeutic agent delivery tip are located sufficiently close such that the therapeutic agent can be delivered into a channel formed by the ablating tip; and (d) a second elongated multi-lumen tube having at least a first lumen and a second lumen, the first lumen supporting the first multi-lumen tube and the second lumen having a proximal end adapted for receiving a second therapeutic agent and extending through the second multi-lumen tube into a second delivery tip, said second lumen adapted for receiving the second therapeutic agent and providing a conduit to the second delivery tip; (e) at least one actuator operatively coupled to said first elongated multi-lumen tube and said second elongated multi-lumen tube, said at least one actuator being operatively transitional between a first retracted configuration, a second intermediate configuration and a third extended configuration, said first elongated multi-lumen tube correspondingly extending distally from said second elongated multi-lumen tube as said at least one first actuator transitions from said first retracted configuration to said second intermediate configuration, and said first elongated multi-lumen tube and said second elongated multi-lumen tube operatively extending equidistantly and along a common axis relative one another as said at least one first actuator transitions from said second intermediate configuration to said third extended configuration; wherein the first therapeutic agent and the second therapeutic agent are dispersed into the tissue simultaneously, in various sequences or according to a timing schedule; f) an outer guide tube adapted for supporting at least a portion of the first and second multi-lumen tubes; and g) a handle assembly for controlling the translation of the second dispensing tip relative to the ablating tip.
