1. A device for transluminal treatment of lesions of tubular organs, that includes:
- (a) an implantable prosthesis comprising an uni- or multilamellar tubular member to which is attached multiple linear members whereby said prosthesis is provided with longitudinal support, and, (b) a deployment instrument for endoluminally implanting said prosthesis comprising;
(i) an outer catheter with an removable inner, coaxial, rigid catheter, and, (ii) a radially compactable member that is substantially porous on expansion to its non-stressed state.

Abstract
An implantable prosthesis for placement in hollow tubular organs is described alongwith an instrument for deploying the said prosthesis. On radial compaction, the prosthesis has a low profile, allowing introduction into the body with a deployment instrument of low calibre. The prosthesis has multiple longitudinal struts to provide longitudinal support. The prosthesis may be provided with helically configured members for circumferential support. The deployment instrument includes a retrievable tool to temporarily secure the prosthesis within the body during the implantation procedure.

10. A method for transluminally treating a disease of a hollow organ, characterized by,
(a) Introduction of the prosthesis and the porous linear member into the organ in a compacted state. (b) Expansion of the liner porous member such that the prosthesis expands to its nominal diameter and is temporarily secured to the inner surface of the organ. (c) Implantation of one or more stents in the prosthesis to permanently secure it to the inner surface of the organ. (d) Advancement of the linear porous member, and implantation of a stent overlapping the leading edge of the prosthesis, or the leading ends of the longitudinal supporting struts. (d) Removal of the linear porous member. (e) Deployment of more stents if deemed warranted.
