US Patent:

6751507, Jun 15, 2004

Filed:

Jul 9, 2001

Appl. No.:

09/901796

Inventors:

George A. Morrison - Foster City CA
Garry L. Carter - Pleasanton CA
Timothy G. Dietz - Fremont CA

Assignee:

Solarant Medical, Inc. - Livermore CA

International Classification:

A61F 200

US Classification:

607101, 607 98, 606 41

Abstract:

Methods, devices, and systems for treating the support structures of the body, particularly for incontinence, take advantage of two mechanisms to enhance the support provided by the fascia, ligaments and tendons: first, the invention increases a modulus of elasticity of these tissues, and particularly of the fascial tissues. The increase in modulus can be effected by directing sufficient energy to the fascial tissue so as to promote the formation of scar tissue. The second mechanism attaches tissue planes together, often by directing energy to an interface between adjacent fascial tissues.

Assignee:

Artemis Medical, Inc. - Hayward CA

International Classification:

A61B 18/18

US Classification:

606 45, 606 41

Abstract:

A tissue-separating catheter assembly comprises a rotatable shaft, having a distal shaft portion, and a tissue separator device extending along the shaft. The tissue separator device has a distal separator part at the distal shaft portion movable between a retracted state, towards the distal shaft portion, and an outwardly extending, operational state, away from the distal shaft portion. A localization device is movable to a radially expanded state. An expandable tubular element is movable so that its outer end is generally axially aligned with the localization device so to capture a separated tissue section therebetween to aid removal of the separated tissue section from the patient.

Appl. No.:

10/045657

Inventors:

George Morrison - San Mateo CA, US
William Dubrul - Redwood City CA, US
Robert Laird - Pinole CA, US

International Classification:

A61B018/14

US Classification:

606/045000

Abstract:

A tissue separator assembly includes a proximal end assembly, typically a handle, and a catheter assembly, including a shaft and a tissue separator movable between a retracted state and an outwardly extending, operational state. An energy source may be selectively coupled to the tissue separator element. The tissue separator element may be moved to the operational state and then automatically rotated to separate a tissue section from the surrounding tissue. A tissue holding element may be used to help secure a separated tissue section to the catheter assembly. A tubular braided element may be used to surround the tissue separator element and any separated tissue section.

ARTEMIS MEDICAL, INC. - Hayward CA

International Classification:

A61B 17/22

US Classification:

606114

Abstract:

A tissue-separating catheter assembly comprises a rotatable shaft, having a distal shaft portion, and a tissue separator device extending along the shaft. The tissue separator device has a distal separator part at the distal shaft portion movable between a retracted state, towards the distal shaft portion, and an outwardly extending, operational state, away from the distal shaft portion. A pivot joint may be used to pivotally connect the distal separator end to the distal shaft portion. The distal shaft portion may comprise a distally-facing transition surface at a proximal end of the distal shaft portion. First and second energizable tissue separator elements may be used at the transition surface and the tip of the device, respectively.
