Patent number: 5507729Abstract: Guide wires for the medical field and which are e.g. used for the introduction of catheters, locks, etc. into the human body and in particular into vessels and organs are disclosed. To avoid the risk of a detachment of parts, the guide wire is provided as a one-piece, highly flexible material guide wire, which has a proximal end portion with a first thickness and following onto the same at least one cross-sectional reduction for increasing the bending flexibility at least in an area connected to the proximal end portion and which in the distal end portion remote from the proximal end portion has portions with a cross-section of the same order of magnitude as that of the proximal end portion. According to a preferred process for producing such a guide wire, a rod-shaped part with a smooth outer wall is drawn continuously and at least once over part of its length from an etching bath attacking its material into a non-etching environment.Type: GrantFiled: January 28, 1994Date of Patent: April 16, 1996Assignee: Angiomed AGInventors: Josef Lindenberg, Wolfram Schnepp-Pesch

Patent number: 5433723Abstract: The invention relates to an apparatus for widening a stenosis in an elongated body cavity such as an artery, the urethra, the ureter, a bile duct or the like, characterized by an endoprosthesis made from a memory alloy with a substantially cylindrical jacket-like outer contour with a lock surrounding and radially holding together the endoprosthesis and with an applicator for the endoprosthesis. It is important that the apparatus is supplied in such a way that in the delivery pack the endoprosthesis is held radially from the outside in its compressed (low temperature) position, which is ensured by the above-described construction of the apparatus according to the invention.Type: GrantFiled: February 28, 1994Date of Patent: July 18, 1995Assignee: Angiomed AGInventors: Josef Lindenberg, Wolfram Schnepp-Pesch
