Patent number: 8475515Abstract: A device for trans-luminal delivery of a self-expanding stent or other surgical device and which is designed for rapid exchange over a guidewire has a guidewire lumen that adjacent its proximal exit port lies side-by-side with the line of the shaft of the device. A sleeve which surrounds and confines the stent has a proximal end that is shaped around the guidewire exit port to show in profile a shape reminiscent of the nose of a dolphin. In preferred embodiments, the sleeve also has a tapered distal tip that is withdrawn proximally over the length of the stent to release it, progressively, from its distal end. The configuration delivers simplicity of design, enhanced performance and reliability in use.Type: GrantFiled: March 24, 2010Date of Patent: July 2, 2013Assignee: Angiomed GmbH & Co., Medizinitechnik KGInventors: Jurgen Dorn, Martin Wüebbeling, Beate Walter

Patent number: 8323326Abstract: A catheter device having a shaft that extends from a proximal end to a distal end to carry on its distal end a self-expanding implant for intraluminal advance on a guidewire and delivery of the implant to an implant site by proximal withdrawal of a longitudinal sheath that lies radially outside the implant in the catheter, the catheter including a first shaft element to pull the sheath proximally and a second shaft element to push the implant distally to prevent the implant moving proximally with the sheath when the sheath is pulled proximally, wherein the sheath is freely rotatable with respect to the first shaft element during the said intraluminal advance and, during proximal movement, is caused to abut the first shaft element at an abutment position by a reduced inner diameter portion of the sheath proximal of the abutment position.Type: GrantFiled: June 16, 2006Date of Patent: December 4, 2012Assignee: Angiomed GmbH & Co.

Publication number: 20120289937Abstract: The present application relates to method of arresting telescopic endwise relative movement in a medical device between an end portion of an elongate member, preferably being a cylinder, and an end portion of a tube, preferably being a cylindrical tube, that receives the end portion of the elongate member. The method is of particular use in the construction of stent delivery systems. In one embodiment, the method comprises providing a length of deformable blocking material; imparting relative endwise movement to draw the blocking material, into the gap and reversing the direction until the blocking material length suffers deformation.Type: ApplicationFiled: July 21, 2010Publication date: November 15, 2012Inventors: Martin Wuebbeling, Daniel Dietrich

Publication number: 20120157935Abstract: The present invention relates to a force-transmitting element for a medical catheter. The element may, for example, be used in catheter introducers or stent delivery systems. An embodiment of the present invention may comprise a tube and a tubular sleeve, wherein the tube has formed through the wall thickness a plurality of axially-distributed slits formed so that the extent of each slit in the circumferential direction exceeds half of the circumference of the tube such that, when the tube is longitudinally flexed into a curve, the slits on the outside of the curve become relatively more opened and, when the element is subject to no external endwise compressive forces, the tube is retained by the tubular sleeve in a state of endwise compression such that the slits are relatively more closed than if the sleeve were absent.Type: ApplicationFiled: July 21, 2010Publication date: June 21, 2012Inventors: Martin Wüebbeling, Jutta Mair
