Patent number: 5579760Abstract: A process for producing an aerosol from a pulverulent substance, particularly for inhalation. In a turbulent agitating or whirling chamber, firstly a vacuum is produced, then gas is allowed to flow into the agitating chamber in such a way that the pulverulent substance contained therein is whirled up and an aerosol is produced, and immediately thereafter aerosol is discharged from the aerosol-containing agitating chamber.Type: GrantFiled: July 10, 1995Date of Patent: December 3, 1996Assignee: Angiomed AGInventor: Dieter Kohler
-
Patent number: 5540713Abstract: An apparatus for widening a stenosis in a body cavity, such as an artery, in the bile duct, in the ureter, etc. is proposed, which in view of a problem-free, reliable and permanent widening of a stenosis is characterized by a memory alloy part having a cylindrical jacket-shaped outer contour, said part radially widening at a transition temperature, which is above ambient temperature, but below body temperature, while maintaining a cylindrical outer contour and at a temperature below the transition temperature the diameter is smaller than that of the vessel.Type: GrantFiled: July 8, 1994Date of Patent: July 30, 1996Assignee: Angiomed AGInventors: Wolfram Schnepp-Pesch, Josef Lindenberg
-
Patent number: 5520697Abstract: An apparatus for correcting a positioning of a stent for widening or keeping open a stenosis, in blood vessels, the urethra, the ureter, etc. The apparatus includes a guide part slidably housing an elongated wire part provided at a forward end thereof with radially expandable wire portions having structures for grasping the stent.Type: GrantFiled: January 12, 1995Date of Patent: May 28, 1996Assignee: Angiomed AGInventors: Josef Lindenberg, Wolfram Schnepp-Pesch
-
Patent number: 5518498Abstract: A stent set for keeping a urethral stenoses open, particularly in the vesical neck, for bladder drainage with an intraurethral catheter having a largely cylindrical basic body, with small baskets or cages at respective ends of the basic end an intraurethral insertion rail and a slide. At a rounded tip with at least one initial opening is provided at a proximal end of the intraurethral catheter.Type: GrantFiled: October 7, 1993Date of Patent: May 21, 1996Assignee: Angiomed AGInventors: Josef Lindenberg, Wolfram Schnepp-Pesch

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
-
Patent number: 5380335Abstract: An apparatus for separating foreign bodies in an elongated organ of a living organism such as a ureter. A collection of stone fragments, such as, for example, kidney stones are crushed by lithotrite and, to prevent accumulation of the fragments an elongated element is provided with the elongated element baffles.Type: GrantFiled: October 14, 1992Date of Patent: January 10, 1995Assignee: Angiomed AGInventor: Guido Dormia

Patent number: 5116352Abstract: An apparatus for removing deposits, such as plaque, in vessels and atherosclerotically transformed wall areas. The apparatus includes a rotary wire and a working coil which extends on the front end of the rotary wire. A ball is provided on a distal end of the working coil; additionally, sharp cutting edges are provided on the ball for engaging and cutting the deposits. The ball is able to rotate eccentrically with respect to a longitudinal axis of symmetry of the working coil.Type: GrantFiled: September 28, 1990Date of Patent: May 26, 1992Assignee: Angiomed AGInventors: Wolfram Schnepp-Pesch, Josef Lindenberg
