Device for causing the release of an object, particularly a prosthesis, into a human or animal passage, and implantation system comprising a catheter and such a device
First Claim
1. A device for causing the release of an object into a human or an animal passage, the object for being carried and delivered into the passage by a catheter which comprises a first sheath and a second sheath which are mounted slidably and telescopically with respect to each other, the catheter for being at least partially inserted into the passage to release the object in response to relative sliding of said first and second sheaths, said device comprising:
- a casing;
a first fixing means for fixing an extracorporal part of said first sheath to said casing;
a mobile carriage mounted on said casing and being movable with respect to the casing;
a second fixing means for fixing an extracorporal part of said second sheath to said mobile carriage;
a controllable drive means comprising a motor for moving said mobile carriage with respect to said casing; and
a programmable element for automatically controlling the motor to release the object according to a pre-established program.

Abstract
Release of an object into a human or an animal passage is performed via a catheter formed of telescopic first and second sheaths. The catheter is at least partially inserted into the passage to release the object in response to relative sliding of the first and second sheaths. The catheter includes a first fixing device that fixes an extra-corporal part of the first sheath to a casing and a second fixing device that fixes an extra-corporal part of the second sheath to a mobile carriage mounted on the casing. A controllable motor moves the mobile carriage with respect to the casing.
