US Patent:

6689131, Feb 10, 2004

Filed:

Mar 8, 2001

Appl. No.:

09/802288

Inventors:

Michael E. McClurken - Durham NH

Assignee:

TissueLink Medical, Inc. - Dover NH

International Classification:

A61B 1818

US Classification:

606 48, 606 41, 606 49, 606 50, 606 51, 607101, 607104

Abstract:

An electrosurgical device for use in surgical procedures is disclosed. The electrosurgical device comprises a main body having a proximal end and a distal end. A heat delivery modality is situated and arranged at the distal end of the main body. A sensor arrangement is also situated and arranged at the distal end of the main body. The heat delivery modality provides thermal energy to a tissue being treated while the sensor arrangement is configured to engage and detect a change in dimension of the tissue being treated. Accordingly, the electrosurgical device of the present disclosure allows a surgeon to precisely achieve the desired amount of dimensional change of the tissue being treated.

Assignee:

Tissuelink Medical Inc. - Dover NH

International Classification:

A61B 1818

US Classification:

606 34, 606 41, 607105

Abstract:

The invention provides a system for treating tissue that includes a power measurement device, a flow rate controller coupled to the power measurement device, and an electrosurgical device configured and arranged to provide radio frequency power and conductive fluid to the tissue, wherein the flow rate controller is configured and arranged to modify a flow rate of the conductive fluid to the tissue, based on signals from the power measurement device. The invention also provides methods and devices for modifying flow rate of conductive fluid to tissue based on measurement of radio frequency power delivered to the tissue.

Assignee:

TissueLink Medical, Inc. - Dover NH

International Classification:

A61B018/18

US Classification:

606 51, 606206

Abstract:

Surgical devices, systems and methods for treating tissue are provided. An exemplary surgical device comprises a tip portion including first and second jaws each having a tissue grasping surface, at least one of the jaws being movable toward the other jaw. The tissue grasping surface of each jaw has includes an electrically insulative surface. The device also includes first and second electrodes connectable to different terminals of an RF generator to generate electrical current flow therebetween, with each of the electrodes having an electrode surface. One of the electrode surfaces is located on one of the jaws separated from one edge of the tissue grasping surface, and the other of the electrode surfaces is located on one or the other of the jaws separated from the other edge of the tissue grasping surface. The device also includes at least one fluid passage being connectable to a fluid source.

International Classification:

A61F 7/00

US Classification:

607 96, 607104, 128898

Abstract:

Medical devices, methods and systems for treating tissue are provided. An exemplary system comprises a fluid from a fluid source, a surgical device which provides energy and the fluid to the tissue and a control mechanism which changes a flow rate of fluid provided from the surgical device and changes a rate of energy provided from the surgical device. The fluid flow rate changes between at least two non-zero flow rates and the energy rate changes between at least two non-zero energy rates. An exemplary method comprises providing a fluid from a fluid source, providing a surgical device which provides energy and the fluid to the tissue, and changing a flow rate of fluid provided from the surgical device with a change in a rate of energy provided from the surgical device. Exemplary devices comprise a tip portion configured to provide energy and a fluid to a tissue.

Assignee:

TissueLink Medical, Inc. - Dovey NH

International Classification:

A61B 18/14

US Classification:

606 50

Abstract:

A medical device () is provided which comprises a catheter tube having a distal end and a lumen, and configured to assist in applying tamponage to a bleeding source in a gastrointestinal tract when flexed. A catheter tip having a catheter tip outer surface is assembled with the tube adjacent the distal end of the tube. The catheter tip comprises a probe body comprising an electrically insulative material, at least one electrode pair located on the probe body which comprises a first electrode spaced from a second electrode, and a fluid distribution manifold to direct a fluid from inside the probe body towards the tip outer surface. The manifold comprises a central passage within the probe body and a plurality of lateral passages which extend from the central passage towards the tip outer surface. An extendable injection needle is housed within the central passage to provide treatment to tissue.
