Device with a prosthesis implantable in the body of a patient
First Claim
1. A system for use in medical treatment of a body, comprising:
- a medical apparatus self-expandable from a reduced profile for inserting the medical apparatus in the body to a expanded profile for deploying the medical apparatus in the body;
a strippable sheath covering the medical apparatus, the sheath maintaining the medical apparatus in the reduced profile position; and
at least one drawstring extending from the sheath, the drawstring being retractable to permit expansion of the medical apparatus.

Abstract
The device comprises a prosthesis designed as a hollow body compressed against the action of restoring spring forces to a cross section reduced relative to an expanded use position, and held in this position by a strippable sheath. After the sheath is stripped, the prosthesis automatically expands to a cross section corresponding to the use position. The sheath, which can be a meshwork in the approximate form of crocheted material, extends over the entire length of the prosthesis and consists of at least one continuous thread and at least one drawstring. The prosthesis, held in the radially compressed position by the sheath, can be mounted displaceably on a feed wire or non-axially-displaceably on the insertion end of a probe or a catheter.

24. A system for use in medical treatment of a body, comprising:
-
a medical apparatus having a distal end and a proximal end, the medical apparatus being expandable between a reduced profile and an expanded profile; and a thread-like strand maintaining the medical apparatus in the reduced profile and having releasable knots, the releasable knots extending the length of the apparatus, the releasable knots being released by pulling an end portion of the strand to allow the medical apparatus to expand into its expanded profile. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49)
