Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
102 words
A reversible-action endoprosthesis delivery device extending between a distal end and a proximal handling end, comprising: an axially extending inner tube surrounded by an outer sheath, the inner tube and outer sheath forming, near a distal end of the inner tube, a chamber adapted to enclose a self-expandable endoprosthesis in a radially contracted state, the inner tube being axially movable relative to the outer sheath to open the chamber; and a remote-activated retaining device, disposed at a proximal end of the chamber, and being adapted to selectively retain or release a proximal end of the endoprosthesis when the chamber is partially opened.
Claim 2
Dependent Claim
102 words
A reversible-action endoprosthesis delivery device extending between a distal end and a proximal handling end, comprising: an axially extending inner tube surrounded by an outer sheath, the inner tube and outer sheath forming, near a distal end of the inner tube, a chamber adapted to enclose a self-expandable endoprosthesis in a radially contracted state, the inner tube being axially movable relative to the outer sheath to open the chamber; and a remote-activated retaining device, disposed at a proximal end of the chamber, and being adapted to selectively retain or release a proximal end of the endoprosthesis when the chamber is partially opened.
Claim 3
Dependent Claim
37 words
A delivery device according to claim 1 wherein the remote-activated retaining means comprises an inflatable balloon fixed to the inner tube, this balloon being connected to pressure means placed at the proximal end of the delivery device.
