Abstract

A device for transluminal implantation of a substantially tubular, radially expansible prosthesis (2), comprising in combination such prosthesis (2) and concentric therewith a flexible probe (1) with means (200) for maintaining said prosthesis (2) in a radially contracted state and for releasing same at the desired location, said means for maintaining and releasing the prothesis comprising a hose (5) concentrically surrounding said probe (1), one end of said hose being connected to the probe (1), and the hose (5) being folded inside itself to form a double-walled section (51, 52) radially surrounding the prothesis (2), the latter being releasable by axial relative movement of the ends of the hose, characterized by inflatable balloon means (30) positioned between said probe (1) and said prosthesis (2) and substantially coextensive with the latter, whereby after releasing the prosthesis at the desired location in the lumen controlled expansion of the prosthesis and the surrounding lumen wall can be achieved by inflating the balloon means; and a method of transluminal implantation using such device.
