Patent number: 9307931Abstract: A system for constructing multiple shells (electronic models) indicative of the geometry and/or volume of a bodily lumen, such as a heart chamber, is configured to collect a plurality of location data points as the electrode is swept within the chamber. Each of the collected data points has an associated measured cardiac phase at which such point was acquired. The system is configured to segregate the collected electrode locations into sets based on the phase. Each set is characterized by a particular, associated phase of its constituent electrode locations. The system is configured to generate, for each set, a respective shell that will represent the chamber at the associated phase. The shells, once constructed, may be used for or in connection with a variety of diagnostic, mapping, and/or therapeutic procedures. The system is also configured to verify that the electrode is in contact with the heart tissue before using the collected data point in the shell construction (e.g.Type: GrantFiled: December 31, 2008Date of Patent: April 12, 2016Assignee: St. Jude Medical, Atrial Fibrillation Division, Inc.Inventors: Israel A.

Publication number: 20100168668Abstract: Catheter systems and methods are disclosed including a seal for helping direct an anticoagulant or other fluid for proper irrigation in a basket catheter. An exemplary basket catheter includes an outer tubing housing an inner fluid delivery tubing having at least one fluid delivery port. A plurality of splines each connected at a proximal end of the splines to the outer tubing and at a distal end of the splines to the inner fluid delivery tubing. The inner fluid delivery tubing is operable to be moved in a first direction relative to the outer tubing to expand the splines to a deployed position. The inner fluid delivery tubing is also operable to be moved in a second direction relative to the outer tubing to collapse the splines to an undeployed position. A porous membrane is provided over at least a portion of the inner fluid delivery tubing having the at least one fluid delivery port.Type: ApplicationFiled: December 29, 2008Publication date: July 1, 2010Inventors: Dale Just, James V.

Publication number: 20080161799Abstract: A catheter for treating tissue is disclosed, the catheter having slotted openings on a circumference of its distal portion, wherein each slotted opening spans at least about 25% of the circumference of the catheter. The disclosed catheter is capable of treating a variety of tissue in a variety of configurations. For example, in an ablation catheter of the disclosed invention, the slotted openings on the distal portion allow the ablation catheter to create effective lesions in both the pulmonary veins and the posterior wall of the left atrium. The ablation catheter preferably carries a conductive medium to help deliver ablation energy (e.g., RF) to the tissue being ablated. The configuration of the catheter permits ablation to be conducted in many varieties and geometric orientations independently of the tissue orientation. Also disclosed is a method of ablating tissue using catheter with slotted openings.Type: ApplicationFiled: December 29, 2006Publication date: July 3, 2008Inventors: Todd Stangenes, Dale Just
