Publication number: 20050283190Abstract: A medical fastener having first undeployed shape for loading into an applier, and a second deployed shape for connecting tissue together. The fastener includes a crown having two ends and first and second legs one attached to each end of the crown. The legs are separated from one another when the fastener is in the first shape. The legs comprise first, second and third layers of material joined together. The first layer of material is a superelastic alloy having a relaxed configuration substantially in the second shape of the fastener. The second layer of material comprising a linear elastic material having a relaxed configuration substantially in the first shape of the fastener. The second layer of material has sufficient rigidity to keep the first layer in the first shape prior to the fastener being deployed. The third layer of material is disposed between the first and second layers and is a material which substantially prevents diffusion between the first and second layers of material.Type: ApplicationFiled: June 16, 2004Publication date: December 22, 2005Inventors: Thomas Huitema, Dieter Stoeckel

Patent number: 6935404Abstract: A stent having marker tabs formed from a micro-alloyed combination of materials provides for more precise placement and post-procedural visualization in a vessel, by increasing the radiopacity of the stent under X-ray fluoroscopy. A unique micro-alloying process is utilized to form the tabs, comprising a first alloy and a second alloy, wherein one of these alloys is radiopaque. This substantially eliminates the possibility of galvanic action between the tab and the stent. This process is also applicable to other medical devices.Type: GrantFiled: November 8, 2002Date of Patent: August 30, 2005Inventors: Thomas Duerig, Mark L. Mathis, Alan Roy Pelton, Dieter Stoeckel

Patent number: 6612012Abstract: A method of manufacturing medical devices of a size sufficiently small to be passed through the vasculature of the body, and more particularly through the small vessels of the brain. The method includes the steps of laser cutting a pattern of apertures in the surface of a tubular workpiece, radially compressing the tubular workpiece to reduce the outer dimensions of the workpiece and heat setting the reduced diameter workpiece to form the very small medical device.Type: GrantFiled: June 11, 2001Date of Patent: September 2, 2003Assignee: Cordis Neurovascular, Inc.Inventors: Vladimir Mitelberg, Dieter Stoeckel

Patent number: 6312455Abstract: A stent for use in a lumen in a human or animal body, has a generally tubular body formed from a shape memory alloy which has been treated so that it exhibits enhanced elastic properties with a point of inflection in the stress-strain curve on loading, enabling the body to be deformed inwardly to a transversely compressed configuration for insertion into the lumen and then revert towards its initial configuration, into contact with and to support the lumen. The shape memory alloy comprises nickel, titanium and from about 3 at. % to about 20 at. %, based on the weight of the total weight of the alloy composition, of a ternary element selected from the group consisting of niobium, hafnium, tantalum, tungsten and gold. The ratio of the stress on loading to the stress on unloading at the respective inflection points on the loading and unloading curves is at least about 2.5:1, and the difference between the stresses on loading and unloading at the inflection points at least about 250 MPa.Type: GrantFiled: April 25, 1997Date of Patent: November 6, 2001Assignee: Nitinol Devices & ComponentsInventors: Thomas Duerig, Dieter Stöckel, Janet Burpee

Patent number: 6312454Abstract: A stent assembly comprises a stent whose configuration can change between a transversely compressed state for delivery into a lumen in a human or animal body, and a relaxed state in which in use the stent contacts the lumen to support it. The stent is positioned in a delivery device and constrained by it in its transversely compressed state. The delivery device comprises a tubular member formed from a shape memory alloy and can be fitted to or within a catheter for delivery of the stent through a lumen.Type: GrantFiled: June 13, 1996Date of Patent: November 6, 2001Assignee: Nitinol Devices & ComponentsInventors: Dieter Stöckel, Thomas Duerig, Janet Burpee

Patent number: 4554027Abstract: A shaped part made of a composite material having shape memory properties is intended to be assembled in such a way that various changes in shape, including complex changes, take place in dependence on the temperature. This is achieved by providing that the shaped part has several sections which have shape memory properties and which are coupled together with one another in such a way that independent results of the shape memory effect cause temperature-specific changes in the shape of the shaped part, in the course of which the shaped part assumes the same number of permanent and/or reversible shapes as the number of sections having shape memory properties.Type: GrantFiled: May 17, 1984Date of Patent: November 19, 1985Assignee: G.
