摘要： Stapler and ablation clamping heads can be interchangeably coupled to a hand-operated actuation mechanism using a quick connect/quick release coupling. In the actuation mechanism, a first user-operable lever controls clamping of the jaws of either head, while a second user-operable lever controls the firing of staples in the stapler head. A removable staple holder may be used with the stapler head to allow easy reloading of staples as well as the use of different sizes and type of staples. A corresponding removable anvil may be used as well. A removable electrode holder may be used with the ablation head to allow the use of different electrode configurations. Moreover, a removable electrode holder may be used over the jaws of a stapler head as an overlay.

摘要： An ablation method and device contacts one surface of a target layer and positions the tissue to ablate entirely through the layer. The tissue may be a wall of the heart (ablated, for example, to form blocking lesions for atrial fibrillation), and ablation may be performed with the heart stopped or beating, and effected by either endocardial or epicardial contact. Access may be through an open incision or a minimally invasive technique involving a small opening through which one or more elongated surgical tools are inserted. Illustratively, an atrial ablation treatment can be performed prophylactically (after CABG), or independently to treat an existing condition. A tool of the present invention has a handle at a proximal end, a bipolar ablation head, and an elongated body interconnecting the handle and the ablation head. A channel or contoured surface fixes and bends the tissue such that inter-electrode conduction paths span the thickness of the layer, thus dependably creating a fully transmural ablation lesion. The oriented transmural energy conduction paths reduce the possibility of inducing coagulation of blood in the heart chamber. One bipolar assembly has an electrode spacing of approximately ten millimeters across a channel of about five millimeters depth. Preferably the ablation head forms a suction holder, connected through internal passages to a vacuum pressure of about 100-500 mmHg, and immobilizes the contacted tissue.

摘要： An patch and sensor assembly for use in an EP mapping system has two portions: a reusable portion and a disposable portion. The reusable portion houses the biosensors used in magnetic based location and mapping systems and the electrical lead necessary to communicate between the biosensor and the mapping system. The reusable portion may also contain a portion of the electrode necessary to receive electrical signals from the body of the patient. The disposable portion of the patch and sensor assembly contains an adhesive covered flexible patch having at least a portion of the electrode used to receive electrical signals form the body of the patient and may contain the electrical lead necessary to communicate such an electrical signal to the mapping system. The disposable portion contains a receptacle adapted to receive and mechanically secure the reusable portion to the disposable portion of the assembly. Such a patch and sensor assembly is useful in hybrid magnetic and impedance based location and mapping systems such as those used in electrophysiology.
