Patent number: 10893932Abstract: An implant having a preferably hollow cylindrical basic structure. A nonwoven fabric is disposed in and/or on the basic structure, the nonwoven fabric preferably comprising biocompatible thermoplastic polyurethane and/or a polymer selected from the group consisting of polylactic acid, polycaprolactone, and a copolymer thereof, and/or a polymer including polyphosphazene. At least in at least one section of the implant, preferably at the proximal and/or distal ends of the implant, fastening means are provided or the nonwoven fabric is treated such that, at least in the expanded state of the implant, the protrusion of nonwoven fabric sections from the implant is significantly reduced. Furthermore, a method for producing such an implant is provided.Type: GrantFiled: March 19, 2019Date of Patent: January 19, 2021Assignee: BIOTRONIK AGInventors: Daniel Wintsch, Stefan Loher, Bodo Quint, Patrice Bachmann, Hans Lang, Dragica Pantic, Alwin Schwitzer

Patent number: 9833547Abstract: The invention relates to a drug-coated balloon catheter and to a method for producing the same. The balloon of the catheter includes (i) a main membrane, and (ii) an asymmetrical polymer membrane which is applied to an outside of the main membrane and into which at least one pharmaceutical active ingredient is introduced.Type: GrantFiled: January 28, 2016Date of Patent: December 5, 2017Assignee: Biotronik VI Patent AGInventors: Michael Tittelbach, Raimund Moehl, Alwin Schwitzer, Matthias Wesselmann, Bodo Quint, Patrice Bachmann

Patent number: 8888741Abstract: A balloon catheter comprises an outer shaft having a distal end, an inner shaft situated therein to form an annular fluid line and projecting beyond the distal end of the outer shaft, and a balloon which is dilatable under the influence of a fluid introduced through the fluid line under pressure. At its proximal end the balloon is attached in a fluid-tight manner to the distal end region of the outer shaft at a first attachment zone, and at its distal end is attached in a fluid-tight manner to the distal end region of the inner shaft at a second attachment zone. Between the attachment zones, in the undilated state the balloon is placed in longitudinal folds along its length. The balloon, at least at its distal end, has an untapered design with a thin wall thickness (d) which is essentially unchanged over the length of the balloon, and the longitudinal folds extend into the attachment zone at that location.Type: GrantFiled: July 31, 2009Date of Patent: November 18, 2014Assignee: Biotronik Vi Patent AGInventors: Arthur Brunner, Adrian Blaser, Matthias Wesselmann, Patrice Bachmann

Patent number: 8778006Abstract: A delivery system having a release mechanism (70) for releasing an object (12), in particular, a supporting body, which is carried by the catheter (20), whereby the catheter (20) has at least one outer shaft (50) which is relatively displaceable toward the object (12) to release the object (12). The catheter (20) has a winding device (100) on its proximal end (24) which winds up a proximal section (52) of the outer shaft (50) to create a relative displacement of the outer shaft (50).Type: GrantFiled: April 27, 2009Date of Patent: July 15, 2014Assignee: BIOTRONIK VI Patent AGInventors: Amir Fargahi, Raimund Moehl, Vesna Colic, Patrice Bachmann
