Claims18
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.
A medical appliance for the treatment of a portion of a body vessel by ionizing radiation, comprising radioactive radiation means and manipulation means, wherein at least a part of the radioactive radiation means forms part of a detachable interlocking engagement between the radioactive radiation means and the manipulation means, the manipulation means comprising distal recess means and stone means and the radioactive radiation means comprising proximal recess means and stone means for cooperation with the distal recess means and stone means of the manipulation means, the stone means of the radioactive radiation means being elastically connected to the radioactive radiation means.
A medical appliance for the treatment of a portion of a body vessel by ionizing radiation, comprising radioactive radiation means and manipulation means, wherein at least a part of the radioactive radiation means forms part of a detachable interlocking engagement between the radioactive radiation means and the manipulation means, the manipulation means comprising distal thread means and the radioactive radiation means comprising proximal coil means for meshing with the distal thread means of the manipulation means.
A medical appliance for the treatment of a portion of body vessel by ionizing radiation, comprising radioactive radiation means and manipulation means, wherein at least a part of the radioactive radiation means forms part of a detachable interlocking engagement between the radioactive radiation means and the manipulation means, the radioactive radiation means consisting of a non-solid radioactive radiation source embedded in a cover of neutral material.
