摘要： Devices and methods are provided for the ablation of regions of the digestive tract to achieve hemostasis and to eradicate chronically bleeding lesions as occur with gastric antral vascular ectasia (GAVE), portal hypertensive gastropathy (PHG), radiation proctopathy and colopathy, arteriovenous malformations, and angiodysplasia. Ablation is typically provided in a wide-field manner, and in conjunction with sufficient pressure to achieve coaptive coagulation. Ablation, as provided the invention, starts at the mucosa and penetrates deeper into the gastrointestinal wall in a controlled manner. Ablation control may be exerted by way of electrode design and size, energy density, power density, number of applications, pattern of applications, and pressure. Control may also be provided by a fractional ablation that ablates some tissue within a target region and leaves a portion substantially unaffected. Embodiments of the device include an ablational electrode array that spans 360 degrees and an array that spans an arc of less than 360 degrees.

The method includes inserting into the lumen an expandable operative element having circuitry with resistivity or inductance that varies according to the circumference of the operative element, varying the expansion of the operative element with an expansion medium, measuring the resistivity of the circuitry, and relating the resistivity or inductance to a value for the circumference of the operative element. In some embodiments the sizing circuit includes a conductive elastomer wrapped around the operative element. Other embodiments of the method apply to operative elements that include an overlapping energy delivery element support in which the overlap varies inversely with respect to the state of expansion, and which is configured with sizing electrodes that sense the amount of the overlap.

摘要： The invention provides a system, devices, and methods for ablating abnormal epithelial tissue of the uterine cervix. Embodiments of an ablation device include an operative head with a support surface adapted to conformably engage and therapeutically contact the cervix, and an energy delivery element on the support surface. The energy delivery element is configured to deliver energy, such as RF energy, to the tissue in a manner that controls the surface area and depth of ablation. The device may further include a shaft and a handle to support the ablation device, and may further include a speculum to facilitate access to the cervix. A system to support the operation of the ablation device includes a generator to deliver energy to the energy delivery element. Embodiments of a method for ablating abnormal cervical tissue include inserting an ablation device intravaginally to contact the cervix, aligning an energy delivery element support surface conformably against a region of the cervix with abnormal tissue, and ablating the tissue.

摘要： A stent comprises at least one stent member woven to form a substantially tubular body that defines a flow path. The tubular body comprises a first region and a second region. In the first region the at least one stent member defines a plurality of first region openings and in the second region at least one first portion of the at least one member and at least one second portion of the at least one member are engaged together to form at least one primary strand. The at least one primary strand defines a plurality of second region openings. The at least one of the plurality of second region openings is in fluid communication with the flow path. The plurality of second region openings provide the second region with a greater porosity than the first region.

摘要： The present invention is directed to systems for occluding an aneurysm having an aneurysmal neck and an aneurysmal inner wall. Generally, a device in accordance with the present invention includes a mesh-like structure that is integrally composed of a shape-memory alloy such as NiTi. The device is deployed within the aneurysm through the aneurysmal neck. The device is configured to be in a deployed state and an undeployed state, and is configured to transition from the undeployed state to the deployed state by exposure to a higher temperature and/or by being unconstrained. The device may function to retain finer vaso-occlusive devices such as vaso-occlusive coils and/or embolic liquids. Furthermore, the device itself may function as a vaso-occlusive device.
