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.
