Patent number: 8540704Abstract: Guided ablation instruments are disclosed for creating lesions in tissue, especially cardiac tissue for treatment of arrhythmias, including atrial fibrillation. In one aspect of the invention, a percutaneous catheter is disclosed with an endoscope positionable in the instrument's distal end region to obtain an image. The image allows the clinician to determine whether contact has been achieved (or blood has been cleared from an ablative energy transmission path) before ablation begins or while ablation is occurring. In one embodiment, percutaneous ablation catheters are disclosed having at least one central lumen and one or more balloon structures at the distal end region of the instrument. Also disposed in the distal end region are an illuminating light source and an endoscope capable of collecting sufficient light to relay an image to the user. The instruments can further include an ablation element.Type: GrantFiled: June 10, 2004Date of Patent: September 24, 2013Assignee: CardioFocus, Inc.Inventors: Gerald Melsky, Jeffrey M.

Patent number: 8187217Abstract: A conduit is provided to provide a bypass around a blockage in the coronary artery. The conduit is adapted to be positioned in the myocardium or heart wall to provide a passage for blood to flow between a chamber of the heart such as the left ventricle and the coronary artery, distal to the blockage. The stent is self-expanding or uses a balloon to expand the stent in the heart wall. Various attachment means are provided to anchor the stent and prevent its migration. In one embodiment, a conduit is provided having a distal top which is more preferably a ball top, wire top, flare top or flip-down top. These top configurations anchor the shunt at one end in the coronary artery.Type: GrantFiled: June 20, 2005Date of Patent: May 29, 2012Inventors: Richard J. Renati, Mark A. Bowen, Stephen C.

Publication number: 20110082450Abstract: A cardiac tissue ablation system includes an elongate catheter configured to deliver a distal end thereof to a patient's heart and an expandable member formed at the distal portion of the catheter. The expandable member has an elastic portion configured to conform to the shape of a target tissue region upon expansion. The expandable member has a plurality of inflation settings that correspond to different levels of inflation of the expandable member. The system also includes a controller for selecting an inflation setting for the expandable member and an energy emitter movably disposed within a lumen of the catheter. The energy emitter is configured to deliver radiant ablative energy to the target tissue region.Type: ApplicationFiled: October 1, 2010Publication date: April 7, 2011Applicant: CardioFocus, Inc.Inventors: Gerald Melsky, Brian Estabrook, Alfred Stancampiano

Publication number: 20110082449Abstract: A method for treating a cardiac condition with visual inspection of a tissue treatment site includes the step of delivering an expanding member formed on a distal end of a catheter to a position adjacent a tissue treatment area within a patient's heart. The expandable member has an elastic portion configured to conform to the tissue treatment area. The method further includes the steps of expanding the expandable member thereby allowing the elastic portion of the expandable member to conform to the tissue treatment area and positioning an energy emitter at a first location within an inner lumen of the catheter. A visible aiming beam is projected during positioning of the energy emitter and ablative energy is delivered from the energy emitter to the tissue treatment area thereby resulting in a first spot lesion.Type: ApplicationFiled: October 1, 2010Publication date: April 7, 2011Applicant: CardioFocus, Inc.Inventors: Gerald Melsky, Susan Ostrowski

Publication number: 20090326320Abstract: Systems for visualizing cardiac tissue during an ablation procedure are provided. In general, the systems include an imaging module configured to measure absorbance data at first and second wavelengths wherein the ratio of these absorbance values identifies the nature of the tissue (e.g., lesion, de novo tissue, etc.). The imaging module can also include a video system having at least two chips with corresponding bandpass filters centered at the first and second target wavelengths. The system can also include a processor and/or video monitor for combining the images produced by the various chips, determining treated and non-treated tissue based on the ratio of absorbance values at the target wavelengths, and displaying images of the treatment area. Methods of visualizing cardiac treatment areas during ablation procedures are also provided herein.Type: ApplicationFiled: April 14, 2009Publication date: December 31, 2009Inventors: Edward L.

Publication number: 20080097561Abstract: Various types of body heating or cooling devices are described in the present disclosure. Such devices, and associated methods, can utilize two separated thermal transfer fluids to promote heating or cooling of a body part. For example, a cooling cap can include a rigid shell and a flexible seal that form a fluid containment space with a patient's head. The rigid shell can include a fluid circulation apparatus disposed within the fluid containment space, and be coupled to a console pump to form a closed loop circulation system. A volume of fluid can be introduced into the fluid containment space to contact the patient's scalp. The console pump can then circulate a thermal transfer fluid through the fluid circulation apparatus to reduce the temperature of a fluid held within the fluid containment space.Type: ApplicationFiled: October 11, 2007Publication date: April 24, 2008Applicant: MedCool, Inc.Inventors: Gerald Melsky, Charles Lennox
