Patent ID: 7074235

Claim:
A device for transluminal treatment of lesions of tubular organs, comprising: (a) an implantable uni- or multilamellar tubular prosthesis with a leading end limited by a leading free edge, and a trailing end limited by a trailing free edge, and a body in between the leading free edge and the trailing free edge, and to which is attached a linear member with a leading end and a trailing end, wherein said trailing end of said linear member is provided with a short peg that has a more prominent profile in cross-section than the linear member, whereby said prosthesis is provided with longitudinal support, and, said linear member is continuous with or bonded to one or more outwardly biased, flexible curvilinear members having good shape memory, and, each curvilinear member has at least one free end, and said free end does not overlap the free end of another curvilinear member when the prosthesis is not radially compressed, and, said one or more curvilinear members are symmetrically attached to the leading free edge of said prosthesis, the radius of curvature of said curvilinear members being equal to the radius of curvature of the prosthesis, whereby said prosthesis is provided with radial support, and, said prosthesis being additionally characterised by a resilient connection between said linear supporting member and at least one curvilinear member, whereby the angle between the said linear supporting member and the said curvilinear member can be reversibly altered by the application of force perpendicular to the plane described by said curvilinear members, and, (b) a deployment instrument for endoluminally implanting said prosthesis comprising: (i) a deployment tool comprising an outer introducer catheter with a leading end limited by a leading edge, and a removable liner, coaxial, rigid catheter with a leading end limited by a leading edge, and, (ii) a delivery tool, which can be detachably fixed to said prosthesis by ex vivo manipulation, whereby said prosthesis can be temporarily held stationary within a tubular organ during implantation, and wherein said delivery tool is comprised of: 1. a narrow thin-walled catheter with a leading end and a trailing end, characterised by a Tuohy-Borst valve attached to said trailing end, and, 2. an axially movable linear detachment member with a leading end and a trailing end, housed within said thin-walled catheter, and characterised by: (Î±) being longer than said thin-walled catheter, and, (Î²) being provided with a recess that can accommodate the peg attached to the trailing end of the linear supporting member of the prosthesis.
