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.
Claims21
A method of implanting a prosthesis in a body of a patient, said prosthesis designed as a hollow body and being compressible against restoring spring forces to a cross section which is reduced relative to an expanded use position, said prosthesis also, after removal of restraining forces that maintain said prosthesis in reduced cross section, expanding automatically to a cross section that corresponds to the use position, comprising the steps of:
- surrounding said prosthesis in said reduced cross section with a strippable sheath formed of at least one continuous thread;
- providing at least one drawstring extendable from the sheath that holds the prosthesis in reduced cross section, and
- retracting said drawstring to remove said sheath and effect automatic expansion of said prosthesis.
