| 20100145331 | Loop Ablation Apparatus and Method - Embodiments of the invention provide an ablation apparatus for ablating target tissue adjacent pulmonary veins of a patient. The ablation apparatus can include a tube capable of being advanced around the pulmonary veins to form a loop. The tube can receive or include electrodes to ablate target tissue. Some embodiments provide a loop ablation device, which may include a cannula and two or more electrode rods carrying two or more bipolar electrodes. The electrode rods can be advanced through the distal ends toward the proximal ends of the loop and toward the target tissue. The bipolar electrodes can receive energy to ablate the target tissue. The bipolar electrodes may be surrounded by the liquid within the cannula while ablating the target tissue. The loop ablation device can further include a rotating grasping mechanism coupled to the electrode rods. | 06-10-2010 |

Some embodiments of the system can include a ring occluder that can be positioned around the left atrial appendage and a ring applicator to position the ring occluder with respect to the left atrial appendage. One embodiment discloses a method of accessing endocardial surfaces of the heart through the atrial appendage. Additional embodiments of the invention provide a clip occluder that can be positioned around the left atrial appendage. A clip applicator can position the clip occluder with respect to the left atrial appendage. | 08-12-2010 |
| 20100262132 | Compound Bipolar Ablation Device and Method - Method and apparatus for ablating target tissue adjacent pulmonary veins of a patient. The ablation device can include a lower jaw assembly including a proximal jaw having a proximal electrode and a distal jaw having a distal electrode, and an upper jaw assembly including an upper jaw having an upper electrode. A proximal actuator can be movable between a first position in which the proximal jaw is open and a second position in which the proximal jaw is clamped with respect to the upper jaw. A distal actuator can be movable between a third position in which the distal jaw is open and a fourth position in which the distal jaw is clamped with respect to the upper jaw. | 10-14-2010 |
| 20110071519 | Clamping Ablation Tool and Method - Method and apparatus for ablating target tissue adjacent pulmonary veins of a patient. A clamping ablation tool can include an upper arm having an upper neck, a link assembly, and an upper actuator. The link assembly can include a distal electrode and a proximal electrode. The clamping ablation tool can include a lower arm that mates with the upper arm. The lower arm can include a lower neck, a distal jaw, and a lower actuator. The distal jaw can include a jaw electrode, and the lower actuator can control movement of the distal jaw. | 03-24-2011 |

| 20090326527 | Cardiac Mapping Instrument with Shapeable Electrode - An instrument including an elongated shaft and a non-conductive handle is disclosed. The shaft defines a proximal section and a distal section. The distal section forms an electrically conductive tip. Further, the shaft is adapted to be transitionable from a straight state to a first bent state. The shaft is capable of independently maintaining the distinct shapes associated with the straight state and the first bent state. The handle is rigidly coupled to the proximal section of the shaft. The instrument is useful for epicardial pacing and/or mapping of the heart for temporary pacing on a beating heart, for optimizing the placement of ventricular leads for the treatment of patients with congestive heart failure and ventricular dysynchrony and/or for use in surgical ablation procedures. | 12-31-2009 |
| 20100145361 | Methods and Devices for Occlusion of an Atrial Appendage - A novel occluder application and clip device for treatment of embolic stroke caused by atrial fibrillation uses multiple sutures in a non directional handle to affix the occlusion device to the applicator and manipulate the occluder from an open and receiving position to a closed and occluding position. The occluder is retained in place by a clamping means related to locks retainers, resilient material or otherwise. An actuator mechanism is used to manipulate the occluder to a locked or occluding position. The applicator with the occluder attached has a low profile and remote manipulations to allow the occluder to be delivered to the clamping location within a patient through a small incision or delivery port such as a trocar cannula or the like. | 06-10-2010 |
| 20100198346 | Method for Guiding a Medical Device - A device and method for valve replacement or valve repair is disclosed comprising the steps of acquiring an anatomical image of a patient, correlating the image to the patient, guiding a valve replacement delivery member or a valve repair delivery member within the patient while tracking the position of the delivery member in the patient, positioning the valve replacement member or valve repair member in a desired position to place a valve or repair valve and removing the delivery member from the patient. In one aspect of the invention, a delivery system is provided for percutaneous delivery of a heart valve to a predetermined position in the heart of a patient, where the delivery system itself includes features that allow it to be accurately positioned in the heart. In another aspect of the invention, a delivery system is provided for percutaneous repair of a heart valve in the heart of a patient, where the repair system itself includes features that allow it to be accurately positioned in the heart. In another aspect of the invention, a method and device are provided that involve imaging a native root using an interoperative technique, then introducing a device that is easily visualized in a chosen imaging modality. | 08-05-2010 |
| 20100217162 | METHODS OF USING HIGH INTENSITY FOCUSED ULTRASOUND TO FORM AN ABLATED TISSUE AREA CONTAINING A PLURALITY OF LESIONS - A device and method for ablating tissue is disclosed comprising the steps of acquiring an anatomical image of a patient, correlating the image to the patient, guiding an ablating member within the patient while tracking the position of the ablating member in the patient, positioning the ablating member in a desired position to ablate tissue, emitting ablating energy from the ablating member to form an ablated tissue area and removing the ablating member from the patient. | 08-26-2010 |
| 20100292749 | Sub-Xiphoid Ablation Clamp and Method of Sub-Xiphoid Ablation - Device and method for sub-xiphoid ablation of patient tissue. A sub-xiphoid access clamp has a handle, an elongate neck coupled to the handle and first and second opposing jaws. The first and second opposing jaws have first and second opposing relief segments being generally co-planar and concave with respect to one another to form a void therebetween, and first and second opposing elongate ablation elements positioned along the first and second opposing jaws and distal of the first and second opposing relief segments relative to the handle. The first and second opposing jaws are articulate between a closed position and an open position to admit, at least in part, a second portion of tissue of the patient within the void created by the first and second opposing relief segments while the first portion of tissue is positioned between the first and second ablation elements in the closed position. | 11-18-2010 |
