Abstract
A coil-reinforced medical device delivery mechanism including a stiff proximal end for enhanced pushability and a soft distal end, including a free floating tip portion, for increased maneuverability and decreased breakage. The system utilizes a non-compliant balloon mounted on a flexible, single lumen shaft device with a support mandrel construction.
Claims29
A reinforced stent delivery system comprising:
- a catheter comprising a reinforced single lumen shaft, wherein the reinforced single lumen shaft further comprises a proximal end and a distal end and wherein a distal head of the catheter is not directly affixed to the reinforced single lumen shaft enabling the distal head to move freely relative to the distal end of the reinforced single lumen shaft;
- a removably attached mandrel support guidewire anchored to the catheter at the proximal end and wherein a distal head of the mandrel support guidewire remains free-floating relative to an extreme distal end of the catheter;
- a thermally bonded balloon mechanism;
- a bonded tip;
- wherein the single lumen shaft and the mandrel support guidewire both possess a variable stiffness profile throughout their respective lengths.

A medical device mechanism comprising:
- a non-compliant balloon device mounted on a flexible, single lumen shaft device comprising a low profile;
- a sheath mechanism;
- and,
- a removable support mandrel positioned inside the single lumen shaft device wherein the single lumen shaft device acts as a guidewire;
- wherein the mandrel extends to a tip of the single lumen shaft device, just beyond a distal end of the non-compliant balloon device, and wherein the mandrel does not extend beyond a distal tip of the single lumen shaft device as the single lumen shaft device is sealed at the tip.
