Filed:

Jan 7, 1999

Appl. No.:

09/227164

Inventors:

David Crotzer - Nashua NH
David DeDonato - Hopedale MA
Jonathan Goodwin - Braintree MA
Stephen Delprete - Rehoboth MA

Assignee:

Thomas Betts International, Inc. - Sparks NV

International Classification:

H01B 314

US Classification:

174 681, 257775, 361767, 361773, 361776

Abstract:

Resilient electrical interconnects are provided which have a non-uniform cross section which achieves an increased range of deflection and a predetermined relationship between compression force and deflection of the interconnect, and between resistance and deflection of the interconnect. A smaller cross sectional area decreases the spring rate, or compression force, of the interconnect during compression. Increased range of deflection and reduced spring rate enables improved compensation for surface irregularities and facilitates mounting of integrated circuit or other devices having large arrays of interconnects. The non-uniform cross section is provided by a single or compound slope, or alternatively a nonlinear curve, from the end of smaller cross-section to the end of larger cross-section.

International Classification:

A61F 206

US Classification:

623 113

Abstract:

A radially deployable covered stent that predictably and dependably expands to an increased diameter state at relatively low deployment pressures while concomitantly minimizing the risk of tearing of the stent covering during expansion. The stent covering includes an inner cover and an outer cover that are bonded together through and around the stent structure to cover the stent. The stent cover is constructed from expanded polytetrafluoroethylene (ePTFE) having a structure of nodes interconnected by fibrils. The stent covering has a radial thickness of at least about 0. 008â and an average internodal distance (IND) of at least about 100 microns when the stent is in the reduced diameter, unexpanded state. The covered stent deploys at an average deployment pressure of less than or equal to about 10 atm. A method for covering a stent structure according to the present invention includes placing a compression member in the form of a tubular sleeve over the outer cover and heating the compressed covered stent to bond the inner cover to the outer cover.

The stent covering includes an inner cover and an outer cover that are bonded together through and around the stent structure to cover the stent. The stent cover is constructed from expanded polytetrafluoroethylene (ePTFE) having a structure of nodes interconnected by fibrils. The stent covering has a radial thickness of at least about 0. 008″ and an average internodal distance (IND) of at least about 100 microns when the stent is in the reduced diameter, unexpanded state. The covered stent deploys at an average deployment pressure of less than or equal to about 10 atm. A method for covering a stent structure according to the present invention includes placing a compression member in the form of a tubular sleeve over the outer cover and heating the compressed covered stent to bond the inner cover to the outer cover.

Inventors:

Jonathan L. Goodwin - Nashua NH, US

Assignee:

Medtronic Vascular, Inc. - Santa Rosa CA

International Classification:

A61F 2/01

US Classification:

606200

Abstract:

A self-expanding filter for collecting emboli or thrombi in a vessel of a patient is disclosed. The filter has a tubular filter body that coils or spirals around an outer surface of an adjacently located, independent treatment device in a corkscrew fashion when deployed from a sheath delivery catheter. When fully deployed, an outer surface of the coiled tubular body conforms to the inner wall of the vessel and an inner surface of the coiled tubular body conforms to an outer surface of the treatment device. The treatment device is disposed within a longitudinal opening extending through the expanded, coiled tubular body of the filter during an interventional procedure.

International Classification:

A61F 202

US Classification:

623 11

Abstract:

A prosthesis is provided that is advantageously used to fill a soft tissue or muscle defect, such as an inquinal or femoral hernia. In a first aspect of the invention, multiple layers of a flexible, mesh material are attach together at a finite number of joins. A tab is placed at the geometric center of one of the mesh layers to facilitate insertion of the mesh into the defect. The tab also creates a blunt tip that reduces irritation and discomfort to the patient. In a second aspect of the invention, a prosthesis is provided that includes a barrier layer between two or more layers of flexible, mesh material to prevent adhesion of the device to the tissue. All layers are attached together by a finite number of joins. A tab is placed at the geometric center of one of the mesh layers to facilitate insertion of the mesh into the defect. The prostheses of the invention are self-forming in that they change from a two dimensional configuration to a three dimensional configuration upon insertion of the device into the defect.

International Classification:

A61F 206

US Classification:

623 113

Abstract:

An expandable prosthesis includes a self-expanding stent deployable between a substantially radially compressed configuration and a substantially radially expanded configuration. A biocompatible coating is attached to at least a portion of the outer surface of the self-expanding stent in the radially compressed configuration to inhibit radially expansion of the self-expanding stent to the radially expanded configuration. The biocompatible material is preferably integrally mounted to the self-expanding stent thus eliminating the need for a separate, independent delivery tube or sheath for maintaining the self-expanding stent in the radially compressed configuration during delivery of the self-expanding stent into a body vessel.

Abstract:

Several different types of electrically conductive elastomers are disclosed along with the methods for their fabrication. In one particular embodiment, a layered composition is disclosed which comprises a substrate, a first layer, and a second layer. The substrate is formed of a non-conductive elastic material and it has an outer surface. The first layer, which is formed with a non-conductive elastic material, is grafted to the outer surface of the substrate. The second layer, which is formed with a non-conductive elastic material having a quantity of conductive flakes interspersed therein, is grafted to an outer surface of the first layer. The second layer can further be formed with a quantity of rounded or jagged conductive particles interspersed in the non-conductive elastic material such that some of the conductive particles are present along an outer surface of the second layer. Alternatively, a quantity of rounded or jagged conductive particles may be imbedded in an outer surface of the second layer.
