US Patent:

7278991, Oct 9, 2007

Filed:

Aug 22, 2001

Appl. No.:

09/938276

Inventors:

David L. Morris - Kogarayi, AU
Steve A. Daniel - Fremont CA, US
Daniel J. Balbierz - Redwood City CA, US

Assignee:

AngioDynamics, Inc. - Queensbury NY

International Classification:

A61B 18/18

US Classification:

606 41, 607101

Abstract:

A method of controlling ablation volume depth includes providing a treatment apparatus. The apparatus comprises a housing having a proximal and distal end including a tissue contacting surface. The housing defines an interior with an energy delivery device positionable in the interior. The energy delivery device includes at least one electrode with a tissue penetrating distal end and is configured to be advanced from the interior into a target tissue site to define an ablation volume. An advancement device is coupled to the energy delivery device and is configured to advance the at least one electrode. The at least one electrode is advanced to a selected deployment depth beneath a tissue surface while avoiding a critical structure. Energy is delivered from the energy delivery device. An ablation volume is created at a controlled depth below the tissue surface responsive to the deployment depth while minimizing injury to the critical structure.

Filed:

Feb 3, 1997

Appl. No.:

8/794733

Inventors:

Steve A. Daniel - Fremont CA
Richard L. Mueller - Byron CA
Robert D. Dowling - Louisville KY

Assignee:

Eclipse Surgical Technologies, Inc. - Sunnyvale CA

International Classification:

A61B 1736

US Classification:

606 15

Abstract:

A TMR energy delivery device is introduced through a first minimally invasive penetration of a patient's chest. Sufficient energy if delivered from the wave guide to the wall of the heart to form a channel through at least a portion of the wall. The device includes a visualization device or camera with a rigid portion and a distal end portion that is flexible, a cup member coupled to a distal end of the flexible distal portion, and a vacuum source coupled to the cup member for providing mechanical stability against the heart wall.

International Classification:

A61B 1818

US Classification:

606 15

Abstract:

An apparatus for performing transmyocardial revascularization provides a closed-chest formation of a channel in a wall of a heart. An articulating scope in one embodiment includes a flexible distal portion which provides for a coupling of a surface of the heart to the distal portion. The articulating distal portion is coupled to a control member to provide articulation. Movement of the control member causes deflection, including articulation, of the generally flexible working end of the scope. The coupler may be a two way valve to provide both vacuum and flushing solutions. The articulating scope can be supported by a scope holder that is table mounted or mounted to the patient. An access port provides for the introduction of tools and instruments. An adaptor couples the access port with a handle. The handle provides a working channel for the introduction of an energy delivery device.
