ABSTRACT:
A device for transluminal implantation of a substantially tubular, radially expansible stent. The device includes a central tube surrounded by an outer tube axially displaceable relative to the central tube, with the radial dimensions of the tubes being such as to form an annular space therebetween capable of accommodating the stent in an unexpanded state. The outer tube is axially displaceable relative to the central tube. In one embodiment of the device, the central tube, at a distal end thereof, is provided with a section of reduced diameter at the proximal end of which there is an undercut groove forming a circumferential flange within which a proximal end of the stent rests until release of the stent by rearward displacement of the outer tube. In a modification of the device, the central tube, at its distal end, includes a sleeve slidably positioned therearound for capturing at least a proximal portion of the stent restraining the proximal portion against movement until stent deployment.
