The device comprises a prosthesis designed as a hollow body which is compressed against the action of restoring forces to a reduced cross section - compared with its expanded in-use shape and it is held in this position by means of an unravellable cover. Once the cover has been unravelled, the prosthesis expands automatically to assume the appropriate cross sectional shape for its in-use position. The cover, which may take the form of a crocheted meshwork, extends over the entire length of the prosthesis and consists of at least one continuous thread and at least one unravelling line. The prosthesis, which is held in the radially compressed position by the cover, can be advanced along a guide wire or it may be mounted in an axially fixed manner on the leading end of a probe or of a catheter. |
