Guidewire For Precision Catheter Positioning

US Patent:
6406442, Jun 18, 2002
Filed:
Apr 12, 1999
Appl. No.:
09/289850
Inventors:
Timothy B. McFann - Redwood City CA
John C. Muskivitch - Cupertino CA
James D. Passafaro - Los Gatos CA
Kathy M. Mah - Mountain View CA
Assignee:
Prolifix Medical, Inc. - Sunnyvale CA
International Classification:
A61B 500
US Classification:
600585, 600434
Abstract:
The present invention comprises a guidewire having a compressible guide section capable of deflecting a catheter to abut a lumen wall. The compressible guide section exerts an outward radial force while it is at least partially compressed within a lumen. The guide section permits a physician to precisely locate a catheter within a body lumen and adjust a catheter tip orientation to be directed to a particular side of a body lumen. A method is disclosed for properly matching a guidewire and a catheter to operate together in the present invention, along with a force measuring instrument to assist in measuring a catheters resistance force value. This method and systems of the present invention involve determining the exact force relationship between the compressible guide section and the resistance of the catheter in vitro.

International Classification:
A61F 206
US Classification:
623 116, 623 135
Abstract:
A bifurcated stent comprises a first stent section and a second stent section. Each stent section is expandable from a predeployed state to a deployed state independently from one another. The second stent section having an end engaged to a receiving region of the first stent section. In the deployed state the first stent section defines a primary flow path and the second stent section defines a secondary flow path in fluid communication with the first flow path. At least a portion of one or both the first stent section and second stent section is constructed from a wire member.

Rolled Minimally-Invasive Heart Valves And Methods Of Manufacture

US Patent:
2003005, Mar 20, 2003
Filed:
Nov 1, 2002
Appl. No.:
10/286009
Inventors:
Matthew Pease - Mountain View CA, US
Brandon Walsh - Livermore CA, US
Jibin Yang - Aliso Viejo CA, US
Travis Rowe - Fremont CA, US
Gregory Mast - Fremont CA, US
Tyson Gustus - San Mateo CA, US
David Forster - Menlo Park CA, US
John Muskivitch - Cupertino CA, US
International Classification:
A61F002/24
US Classification:
623/002110, 623/002180, 623/901000, 623/904000
Abstract:
Expandable heart valves for minimally invasive valve replacement surgeries are disclosed. The valves are rolled into a first, contracted configuration for minimally invasive delivery using a catheter, and then unrolled or unfurled at the implantation site. One- and two-piece stents may be used in conjunction with a plurality of flexible leaflet-forming membranes. The stents may include an annulus section, a sinus section with the membranes attached over sinus apertures, and an outflow section. Lockout tabs and making slots secure the stents in their expanded shapes. Alignment structure ensures concentric unfurling of the stent. Anchoring elements at the stent edges or in the stent body secure the valve within the annulus. A method of manufacture includes shape setting the sheet-like stent to ensure an outward bias during deployment. The stent may also include dear tracks for engagement with a gear mechanism for deployment. The stent is desirably made of a superelastic material such as Nitinol and may have areas removed or thinned to reduce the bending stresses when rolled into its small spiral for catheter delivery.

Methods And Systems For Endovascularly Clipping And Repairing Lumen And Tissue Defects

US Patent:
8551132, Oct 8, 2013
Filed:
Apr 19, 2007
Appl. No.:
11/737700
Inventors:
Joseph Eskridge - Clyde Hill WA, US
Gilbert Clarke - Seattle WA, US
Matthew Pease - Mountain View WA, US
Gregory Martin Mast - Freemont CA, US
John Conrad Muskivitch - Cupertino CA, US
Assignee:
Pulsar Vascular, Inc. - San Jose CA
International Classification:
A61M 29/00
US Classification:
606191, 606200, 606213, 623 111
Abstract:
An implantable closure structure is delivered using minimally invasive techniques, and inhibits the migration of liquid and particulate matter from inside a physiological cavity or opening, such as an aneurysm or a septal defect, as well as inhibiting the flow of liquid and particulate matter, such as from an associated blood vessel or chamber, into the physiological cavity or opening. The device has a closure structure that covers the neck or opening of a cavity and has one or more anchoring structures for supporting and retaining the closure structure in place across the cavity or opening.

International Classification:
A61F 2/06
US Classification:
623 135
Abstract:
A bifurcated stent includes a first stent section and a second stent section. The first stent section is balloon expandable, has an unexpanded configuration, an expanded configuration, and a tubular wall defining a secondary opening. The secondary stent section is self-expanding and an end of the secondary stent section is engaged to a portion of the tubular wall of the primary stent section defining the secondary opening. The secondary stent section has an unexpanded configuration with a first length and an expanded configuration with a second length where the first length is less than the second length. The secondary stent section is expanded to the expanded configuration after the primary stent section is expanded to the expanded configuration. The secondary stent section forms a portion of the tubular wall of the primary stent section in the unexpanded configuration.
