| 20090082620 | Methods and Apparatus Providing Suction-Assisted Tissue Engagement Through a Minimally Invasive Incision - Suction-assisted tissue-engaging devices, systems, and methods are disclosed that can be employed through minimal surgical incisions to engage tissue during a medical procedure through application of suction to the tissue through a suction member applied to the tissue. A shaft is introduced into a body cavity through a first incision, and a suction head is attached to the shaft via a second incision. The suction head is applied against the tissue by manipulation of the shaft and suction is applied to engage the tissue while the medical procedure is performed through the second incision. A system coupled to the shaft and a fixed reference point stabilizes the shaft and suction head. When the medical procedure is completed, suction is discontinued, the suction head is detached from the shaft and withdrawn from the body cavity through the second incision, and the shaft is retracted through the first incision. | 03-26-2009 |
| 20100114136 | CUTTING DEVICE AND METHOD OF VESSEL HARVESTING - Embodiments of the invention provide a cutting device and method of vessel harvesting. The cutting device can include at least one tubular member, a cutting element, and a centering member. The cutting device can include at least one tubular member with a flexible section and a cutting element. The method of vessel harvesting can include spacing a cutting element of the cutting device from the vessel as the cutting element is advanced over the vessel. | 05-06-2010 |
| 20100121362 | VESSEL SUPPORT DEVICE AND METHOD OF VESSEL HARVESTING - Embodiments of the invention provide a vessel support system and a method of vessel harvesting. The system can include a cutting device, a catheter adapted to be inserted into a section of the vessel in order to support the vessel as the cutting device is advanced over the vessel, and a cannula adapted to be coupled to the vessel and adapted to receive the catheter as the catheter is inserted into the section of the vessel. The method can include orienting a cutting device coaxially with the cannula and the catheter and advancing the cutting device over the cannula, the catheter, and the section of the vessel in order to core out the section of the vessel and a portion of the surrounding tissue. | 05-13-2010 |

| 20090270857 | Ablation Device with Jaws - System, device and method for ablating target tissue adjacent pulmonary veins of a patient through an incision. An ablation device can include a hinge including a cam assembly, a moving arm, a floating jaw, and a lower jaw. Fingers can engage the floating jaw to hold the floating jaw in a first position with respect to the moving arm. Some embodiments of the invention can provide an ablation device including a central support, an upper four-bar linkage coupled to the central support, an upper jaw coupled to the upper linkage, a lower four-bar linkage coupled to the central support, and a lower jaw coupled to the lower linkage. Some embodiments of the invention can provide an ablation device having an upper jaw including a first cannula connection and a lower jaw including a second cannula connection. The system can include a first catheter coupled to the first cannula connection and a second catheter coupled to the second cannula connection. The first and second catheters can be inserted through the incision and can move the upper and lower jaws adjacent the pulmonary veins. | 10-29-2009 |
| 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 |
| 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 |
| 20100298824 | Bipolar Ablation Device, System and Method for Minimally Invasive Isolation of Pulmonary Veins in a Sub-Xiphoid Approach - Structure and method for using a sub-xiphoid ablation clamp for ablating tissue of a patient. The clamp has an elongate shaft having a major axis, first and second opposing jaws configured to open and close along a first plane, a first and second ablation element positioned along the first and second jaws configured to ablate the tissue positioned therebetween, an actuable joint operatively coupled between the shaft and the opposing jaws and configured to move the opposing jaws to a selectable angle relative to the major axis of the elongate shaft along a second plane orthogonal to the first plane. The ablation clamp has a handle operatively coupled to the shaft having an actuator configured to actuate the actuable joint and a trigger mechanism to open and close the opposing jaws. | 11-25-2010 |
| 20100305398 | Methods and Devices for Stabilizing Tissue - Tissue stabilizers including a clamp assembly, a turret assembly, an articulating arm having a tension element extending therethrough, a collet assembly and a head-link assembly are disclosed.
