Abstract
An endoluminal prosthesis deployment device includes a hollow plunger which is slideably mounted on a narrow inner catheter and an outer sheath through which the catheter and the plunger are slideable. The distal end of the plunger is provided with a soft retractor bulb and the distal end of the inner catheter is provided with a dilator tip. The proximal end of the plunger is provided with a locking mechanism for temporarily locking the relative positions of the plunger and the catheter and the proximal end of the outer sheath is provided with a locking mechanism for temporarily locking the relative positions of the plunger and outer sheath. The deployment device according to the invention accommodates protheses of different length by adjusting the distance between the distal end of the plunger and the dilator tip. This distance is adjusted by moving the plunger and/or the catheter relative to each other and locking their relative positions with the locking mechanism on the plunger. In addition, the retractor bulb provides a secure coupling of the distal end of the plunger to the proximal end of an endoluminal prosthesis such that the prosthesis may be retracted back into the outer sheath even after it is 80% deployed.
