Patent number: 7052516Abstract: A spinal disc annulus repair stent for repair and reconstruction of the spinal disc wall (annulus) after surgical invasion or pathologic rupture, which may incorporate suture closure or other means of stent insertion and fixation, designed to reduce the failure rate of conventional surgical procedures on the spinal discs. In an illustrative embodiment, the design of the spinal disc annulus stent advantageously allows ingrowth of normal cells of healing in an enhanced fashion strengthening the normal reparative process.Type: GrantFiled: April 29, 2002Date of Patent: May 30, 2006Assignee: Anulex Technologies, Inc.Inventors: Joseph C.

Patent number: 6872216Abstract: An emboli capturing system captures emboli in a body lumen. A first elongate member has a proximal end and a distal end. An expandable emboli capturing device is mounted proximate the distal end of the first elongate member, and is movable between a radially expanded position and a radially contracted position. When in the expanded position, the emboli capturing device forms a basket with a proximally opening mouth. A second elongate member has a proximal and a distal end with a lumen extending therebetween. The lumen is sized to slidably receive a portion of the first elongate member. An expandable delivery device is mounted to the distal end of the second elongate member and is movable from a radially retracted position to a radially expanded position. The delivery device has a receiving end configured to receive the emboli capturing device, and retains at least the mouth of the emboli capturing device in a radially retracted position.Type: GrantFiled: January 17, 2003Date of Patent: March 29, 2005Assignee: SciMed Life Systems, Inc.Inventors: John M.

Publication number: 20040010280Abstract: A method and system of performing an intravascular procedure at a treatment site in a vessel of a patient. A device creates a seal to prevent the flow of blood during the treatment of vascular disease. A seal may be formed between the distal inside diameter of a sheath or catheter such as a guide catheter as well as within a vessel, such as an artery or vein. An elongated device having a distal portion extending from the catheter and having a fluid impermeable membrane disposed about at least the distal end of the device is used to seal the vessel. The system includes a device to occlude blood flow and a distal protection device to filter or remove embolic debris.Type: ApplicationFiled: July 12, 2002Publication date: January 15, 2004Inventors: Daniel O.

Publication number: 20030233117Abstract: Catheters, assemblies, and methods for delivering and recovering embolic protection devices. Catheters are provided that can be advanced over single length guide wires and which can be retracted over single length wire shafts of distal embolic protection devices. One catheter is a two-port catheter having two sidewall ports, a distal end port, and a proximal end port. The two-port catheter can be advanced over a guide wire threaded between the distal end port and the distal sidewall port. An embolic protection device wire shaft can be back loaded into the distal end port and out the proximal sidewall port. A three-port catheter includes a distal end port, and distal, intermediate, and proximal sidewall ports. The distal sidewall port can be dimensioned to accept passage of a filter body through the port. The distal end port can be dimensioned to accept only a guide wire to provide a smooth transition from the guide wire to the small profile distal end.Type: ApplicationFiled: June 14, 2002Publication date: December 18, 2003Inventors: Daniel O.

Patent number: 6533755Abstract: A catheter assembly including a balloon which incorporates a reverse-cone design for improved stent delivery. The reverse-cone design provides an inflatable area which extends longitudinally over the balloon waist. When folded or deflated, the portions of the balloon extending over the waist in conjunction with the waists provide a bulky mass onto which a stent may be securely crimped without the use of additional structure under the balloon.Type: GrantFiled: February 1, 2001Date of Patent: March 18, 2003Assignee: SciMed Life Systems, Inc.Inventor: Daniel O.

Patent number: 6518387Abstract: The present invention relates to a soybean-based adhesive resin including a soybean flour and a cross-linking agent. The cross-linking agent is reacted with the functional groups in the soybean flour to form an adhesive resin. The present invention also relates to a method of making a soybean-based adhesive resin. This method involves providing an aqueous solution of soybean flour and adding a cross-linking agent to the solution under conditions effective to cross-link the soybean flour so that an adhesive resin is formed. Also disclosed is a composite product which includes particulate plant material and the soybean-based adhesive resin. The adhesive is prepared by reacting the cross-linking agent with the functional groups in the soybean flour. The present invention also relates to a method of making a composite product by providing particulate plant material and applying the soybean-based adhesive resin to the particulate plant material.Type: GrantFiled: September 4, 2001Date of Patent: February 11, 2003Assignee: Iowa State University Research Foundation, Inc.Inventors: Monlin Kuo, Deland J.

Patent number: 6443912Abstract: An apparatus for exchanging over-the-wire balloon catheters engages a guide wire within a guide catheter. In one embodiment the engagement is by an inflatable balloon in the guide catheter. Alternatively, the engagement is accomplished by a captivation wire in the guide catheter that has a collapsible loop portion through which the guide wire extends. Inflation of the balloon or closing the loop portion of the captivation wire within the guide catheter traps the guide wire and restricts its movement relative to the guide catheter. Once the guide wire position is fixed, withdrawal of a first balloon catheter and subsequent introduction of a second balloon catheter over the guide wire is possible without moving the guide wire longitudinally. Thus, the positioning of the guide wire over a stenosis to be dilated is not disturbed.Type: GrantFiled: November 8, 1991Date of Patent: September 3, 2002Assignee: SciMed Life Systems, Inc.Inventors: Christian L. Mazzola, Peter T. Keith, Daniel O. Adams
