US Classification:

606 15, 606 7, 606 16, 607 88, 607 89

Abstract:

An apparatus for forming a lesion in cardiac tissue includes an optical fiber for guiding a coherent waveform of a selected wavelength to a fiber tip. The wavelength is selected to have a low absorption in water. The fiber tip is contained within a guide member having a discharge bore for a direction of energy discharge to define an unobstructed light pathway from the fiber tip through a discharge end of the discharge bore. A fluid pathway is in fluid flow communication with the guide member to admit a bio-compatible flushing fluid to the discharge bore.

Abstract:

An apparatus for treating a biological tissue of a patient in situ includes an optical fiber for guiding a coherent waveform of a selected wavelength to a fiber tip. The wavelength is selected to have a low absorption in water. The fiber tip is contained within a guide member having a discharge bore to define an unobstructed light pathway. The guide member is adapted to be slidable along a tissue surface in atraumatic sliding engagement with the discharge bore opposing the surface. The guide member is carried on an elongated flexible member.

Assignee:

Medical CV, Inc. - Inver Grove Heights MN

International Classification:

A61B 18/14

US Classification:

606 34, 606 41, 600374

Abstract:

A method and apparatus for treating a body tissue in situ (e. g. , an atrial tissue of a heart to treat) atrial fibrillation include a lesion formation tool is positioned against the heart surface. The lesion formation tool includes a guide member having a tissue-opposing surface for placement against a heart surface. An ablation member is coupled to the guide member to move in a longitudinal path relative to the guide member. The ablation member has an ablation element for directing ablation energy in an emitting direction away from the tissue-opposing surface. The guide member may be flexible to adjust a shape of the guide member for the longitudinal path to approximate the desired ablation path while maintaining the tissue-opposing surface against the heart surface. In one embodiment, the ablation member includes at least one radiation-emitting member disposed to travel in the longitudinal pathway. Transmurality can be assessed to approximate a location of non-transmurality in a formed lesion.

International Classification:

A61B 18/22

US Classification:

606 12, 128898, 606 10, 606 13

Abstract:

A method and apparatus for treating in situ biologic tissue include identifying a patient with a condition susceptible to treatment by forming a lesion in the tissue and accessing a surface of the tissue. A lesion formation tool is positioned against the accessed surface. The tool includes an optical fiber for guiding a coherent waveform of a selected wavelength to a fiber tip for discharge of light energy from the fiber tip. The wavelength is selected for the light energy to penetrate a full thickness of the tissue to form a volume of necrosed tissue through the thickness of the tissue. The tool further includes a guide tip coupled to the fiber tip. The guide tip is adapted to have a discharge bore aligned with the fiber tip to define an unobstructed light pathway from the fiber tip to the tissue surface. The guide tip is further adapted to be placed against the tissue surface with the guide tip slidable along the tissue surface in atraumatic sliding engagement with the discharge bore opposing the tissue surface. The lesion formation tool is manipulated to draw the guide tip over the tissue surface in a pathway while maintaining the discharge bore opposing the tissue surface to form a transmural lesion in the tissue extending a length of the pathway.

Assignee:

AngeLase, Inc. - Plymouth MN

International Classification:

A61N 139

US Classification:

128419D

Abstract:

An electrophysiologically guided arrhythmia ablation system for ventricular tachycardia or other arrhythmias. The system includes recording the electrical activation time of various parts of the heart for locating the active site of the arrhythmia. The system has the capability of processing local myocardial electrical activation data. The process includes identification of an active site which occurs during the 20-80%, preferably 35-50%, time period of a diastolic interval. The diastolic interval is monitored by appropriate electrical connections between the heart and a monitor. A mapping device connects to the monitor which maps for indicating an active site. The active site is then a site for preferred placement of an electrode for a defibrilator.
