Apparatus and methods for compression of endoluminal prostheses
First Claim
1. An endoluminal prosthesis system comprising:
- a tubular body having a lumen;
a radially compressible endoluminal prosthesis having an end with a plurality of engageable structures radially disbursed thereabout;
a plurality of tensionable flexible filament loops, wherein each loop extends radially from the lumen of the tubular body to engage an engageable structure and returns back toward the tubular body so that tensioning the loops draws the end of the prosthesis radially inward toward the lumen; and
a sheath which is slidable distally over the prosthesis when the loops are tensioned to compress the prosthesis adjacent the engageable structures.

Abstract
The present invention provides devices and methods to promote the compression and/or recapture of endoluminal prostheses. An endoluminal prosthesis system generally comprises a tubular body and a radially compressible endoluminal prosthesis. The tubular body includes a lumen, while the prosthesis has a proximal end with a plurality of engageable structures radially disbursed thereabout. Each of a plurality of filaments extends distally from the lumen of the tubular body to an engageable structure so that tensioning of the filaments radially compresses the proximal end of the prosthesis. Preferably, a sheath then slides over the prosthesis, the sheath ideally having a plurality of axially oriented runners which form a radially flared structure to smoothly compress the prosthesis therebetween.

12. An endoluminal prosthesis system comprising:
-
a tubular body having a lumen, a proximal end, and a distal end; a radially compressible endoluminal prosthesis having a proximal end with a plurality of proximally oriented apices radially disbursed thereabout; and a plurality of flexible filament loops, wherein each loop extends radially outward from the distal end of the tubular body, engages an apex of the prosthesis, returns radially inward back to the tubular body, and passes through the lumen to the proximal end of the tubular body; and a sheath which is slidably disposable over the tubular body; wherein tensioning the loops from the proximal end of the tubular body draws the apices of the prosthesis radially inward to facilitate advancing the sheath distally over the prosthesis so as to radially compress the prosthesis. - View Dependent Claims (13)
