Patent number: 10575902Abstract: Methods and devices for measuring the size of a body lumen and a method for ablating tissue that uses the measurement to normalize delivery of ablational energy from an expandable operative element to a luminal target of varying circumference are provided. The method includes inserting into the lumen an expandable operative element having circuitry with resistivity or inductance that varies with 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 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 electrodes that sense the amount of the overlap.Type: GrantFiled: October 23, 2015Date of Patent: March 3, 2020Assignee: Covidien LPInventors: Michael P.

Patent number: 10278774Abstract: In one embodiment, a device is provided including an expandable support member having a first portion and a second portion is provided. The first portion is adapted to have a smaller expansion index than the second portion. A therapeutic or diagnostic instrument is supported, at least in part, by the expandable support member first portion. In another embodiment, the support member is adapted for non-uniform expansion of the first and second portions. There are also described methods of forming therapeutic devices. There are also described methods of providing therapy to tissue in a body by positioning a device in proximity to tissue in a body selected to receive therapy. Next, the expandable support member second portion is expanded until the instrument is at a therapeutic position relative to the tissue in a body selected to receive therapy. Thereafter, therapy or diagnosis is provided to the selected tissue using the device.Type: GrantFiled: March 18, 2011Date of Patent: May 7, 2019Assignee: COVIDIEN LPInventors: Michael P.

Patent number: 9314326Abstract: 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.Type: GrantFiled: April 21, 2011Date of Patent: April 19, 2016Assignees: Stryker Corporation, Stryker European Holdings I, LLCInventors: Michael Wallace, Joseph Eder, Brent C.

Patent number: 8439908Abstract: 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.Type: GrantFiled: July 3, 2008Date of Patent: May 14, 2013Assignee: Covidien LPInventors: David S.
