Patent number: 8663541Abstract: The present invention relates to a medical device and method of forming the medical device. In particular, the present invention relates to a medical device having a tubular membrane structure over a radially expandable structural frame, and to a method of forming the tubular membrane on the radially expandable structural frame. In one aspect, a structural frame is placed over a spinning mandrel and a fiber is electro-statically spun over at least a portion of the structural frame forming a membrane. A transfer sheath may be used between the mandrel and structural frame to prevent the electro-statically spun fiber from adhering to the mandrel. In another aspect, a first membrane is spun over the mandrel before the structural frame is placed over the mandrel. In this aspect, at least a portion of the structural frame is sandwiched between the membranes. The membrane or membranes and structural frame form a fiber spun frame assembly. The fiber spun frame assembly may be coated with an elastic polymer.Type: GrantFiled: August 21, 2007Date of Patent: March 4, 2014Assignee: Cordis CorporationInventors: Iksoo Chun, Mark B. Roller, David Christopher Majercak

Patent number: 7572298Abstract: An implantable medical device is disclosed. The device is fabricated at least in part from a biocompatible, biodegradable composition. The composition is composed of a biocompatible, biodegradable polymer and a biocompatible, biodegradable wax. The concentration of the wax at the surface of the device is greater than the concentration of the wax in the body of the implantable device. The increased concentration of wax at the device surface may be attained when the device is heated to a temperature greater than the melting point of the wax and the glass transition temperature of the polymer, but lower than melting point of the polymer.Type: GrantFiled: March 28, 2003Date of Patent: August 11, 2009Assignee: Ethicon, Inc.Inventors: Mark B.
