Abstract
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.

Independent Claim
107 words
An endoluminal prosthesis deployment device for use with an endoluminal prosthesis, said device comprising: a) an outer sheath having a proximal end and a distal end; b) an inner plunger having a proximal end and a distal end, said inner plunger slideably disposed within said outer sheath; and c) prosthesis gripping means on said distal end of said inner plunger for engaging a proximal end of a prosthesis and drawing the prosthesis into said distal end of said outer sheath without engaining the distal end of the prosthesis when the prothesis is completely drawn into said outer sheath, said prosthesis gripping means comprises a soft tear-resistant bulb.
Claim 2
Dependent Claim
107 words
An endoluminal prosthesis deployment device for use with an endoluminal prosthesis, said device comprising: a) an outer sheath having a proximal end and a distal end; b) an inner plunger having a proximal end and a distal end, said inner plunger slideably disposed within said outer sheath; and c) prosthesis gripping means on said distal end of said inner plunger for engaging a proximal end of a prosthesis and drawing the prosthesis into said distal end of said outer sheath without engaining the distal end of the prosthesis when the prothesis is completely drawn into said outer sheath, said prosthesis gripping means comprises a soft tear-resistant bulb.
Claim 3
Dependent Claim
15 words
A device according to claim 2, wherein: said bulb has a substantially frustroconical distal end.
Claim 4
Dependent Claim
30 words
A device according to claim 3, wherein: said distal end of said bulb has an outer diameter which is substantially the same as an inner diameter of said outer sheath.
