Filed:

Oct 23, 2006

Appl. No.:

11/552075

Inventors:

Chad Allen Lieber - Chino Hills CA, US
Ariel Garcia - Duarte CA, US
Shiva Sharareh - Laguna Niguel CA, US

Assignee:

Biosense Webster, Inc. - Diamond Bar CA

International Classification:

A61B 18/04

US Classification:

606 32, 606 2, 606 34, 600475, 600477

Abstract:

A system and method that enable real-time optical measurements of tissue reflection spectral characteristics while performing ablation, involves the radiation of tissue and recapturing of light from the tissue to monitor changes in the reflected optical intensity as an indicator of steam formation in the tissue for prevention of steam pop. The system includes a catheter adapted to collect light reflected from tissue undergoing ablation, a detection component that identifies and separates constituent wavelengths of collected light, a quantification apparatus for generating measured light intensity data for the collected light, and a processor that analyses the measured light intensity data in relation to time. The system may include a graphical display and/or an audio output (e. g. , speaker) that provide visual and/or audio alarm when the system infers formation of a steam pocket in the tissue.

US Classification:

600424, 600145, 600 12, 606 41

Abstract:

A medical probe includes a flexible insertion tube, having a distal end for insertion into a body cavity of a patient, and a distal tip, which is disposed at the distal end of the insertion tube and is configured to be brought into contact with tissue in the body cavity. A coupling member couples the distal tip to the distal end of the insertion tube and includes a tubular piece of an elastic material having a helical cut therethrough along a portion of a length of the piece.

International Classification:

A61B 18/18
A61B 5/05

US Classification:

606 41, 600424, 600145, 600 12

Abstract:

A medical probe includes an insertion tube, having a longitudinal axis and having a distal end. A distal tip is disposed at the distal end of the insertion tube and is configured to be brought into contact with a body tissue. A joint couples the distal tip to the distal end of the insertion tube. A joint sensor, contained within the probe, senses a position of the distal tip relative to the distal end of the insertion tube. The joint sensor includes first and second subassemblies, which are disposed within the probe on opposite, respective sides of the joint and each include one or more magnetic transducers.

International Classification:

US Classification:

606 34, 606 32

Abstract:

A system for measuring real-time tissue reflection spectral characteristics during ablation includes a catheter for collecting light reflected from tissue undergoing ablation, a detection component for separating constituent wavelengths of the collected light, a quantification apparatus for generating measured light intensity data of the collected light, and a processor for analyzing the data in relation to time. A method for monitoring formation of steam pop during ablation includes delivering light to tissue, delivering ablative energy to the tissue, measuring the reflectance spectral intensity of the tissue, and observing whether the measured reflectance spectral intensity (MRSI) initially increases in a specified time period followed by a decrease at a specified rate. If the MRSI does not decrease, delivery of ablation energy continues. If the MRSI decreases within the specified time at the specified rate, formation of a steam pocket is inferred and delivery of ablative energy is decreased or discontinued.
