| 摘要 |
A device for transluminal implantation of a substan- tially tubular, radially expansible stent, comprising a central tube or rod surrounded by an outer tube axially displaceable relative said central tube or rod, the radial dimensions of said tubes or tube and rod being such as to form an annular space therebetween capable of accommoda- ting said stent in an unexpanded state, and means for axial displacement of said outer tube relative to said central tube or rod. In said device the central tube or rod, 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 said stent rests until release of the stent by rearward displacement of said outer tube.
