Patent ID: 8328841

Claim:
An endoscopic embolization coil delivery system for use in treating a lesion within the gastro intestinal tract of a human patient, the delivery system comprising: an ultrasonically detectable delivery device comprising an elongate shaft sized to be advanced through a working channel of an endoscope, the shaft having a sufficient length to reach a target tissue within the gastro intestinal tract of a patient, wherein the shaft comprises a first lumen and a second lumen extending therethrough, the first lumen comprising an opening at a distal end of the delivery device, the second lumen intersecting the first lumen near the distal end of the delivery device; an embolization coil comprising a continuous wire extending between a distal end and a proximal end, the wire having a substantially uniform cross-section without any discontinuities between the distal and the proximal ends thereof, the embolization coil being disposed within the first lumen of the delivery device, the embolization coil configured to be deployed into the target tissue for effecting a treatment thereof; a deployment device disposed within the first lumen of the delivery device, the deployment device being adapted to eject the embolization coil from the opening at the distal end of the delivery device and into the target tissue, and a means for separating the embolization coil into a plurality of separate embolization coils having different lengths upon deployment of at least a portion of the embolization coil into the target tissue, the means for separating comprising a cutting implement located proximate the distal end of the delivery device, the cutting implement being movably disposed within the second lumen of the shaft and operably connected to a proximal end of the delivery device, wherein the cutting implement comprises an electrosurgical wire that is configured to ensnare and sever the wire of the embolization coil into the plurality of separate embolization coils upon delivery of the at least a portion of the embolization coil into the target tissue, the electrosurgical wire being configured to sever the wire of the embolization coil at any location between the distal and proximal ends of thereof.
