Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
93 words
A medical appliance for the endoluminal treatment of a portion of a body vessel by ionizing radiation, comprising radioactive radiation means, a catheter for insertion into the lumen of the body vessel, the catheter having a longitudinal lumen extending therethrough, a manipulation wire for advancing and removing the radioactive radiation means into and from the longitudinal lumen of the catheter, and detachable interlocking engagement means disposed within the catheter lumen, wherein the engagement means secures a detachable interlocking engagement between at least a part of the radioactive radiation means and the manipulation wire.
Claim 2
Dependent Claim
93 words
A medical appliance for the endoluminal treatment of a portion of a body vessel by ionizing radiation, comprising radioactive radiation means, a catheter for insertion into the lumen of the body vessel, the catheter having a longitudinal lumen extending therethrough, a manipulation wire for advancing and removing the radioactive radiation means into and from the longitudinal lumen of the catheter, and detachable interlocking engagement means disposed within the catheter lumen, wherein the engagement means secures a detachable interlocking engagement between at least a part of the radioactive radiation means and the manipulation wire.
