摘要: An expandable frame for an embolic filtering device used to capture embolic debris in a body vessel includes a first half frame having a first control arm connected to a second control arm by a partial loop and a second half frame having a first control arm connected to a second control arm by a partial loop. The partial loops cooperatively form a composite loop for attachment of a filtering element which will expand in the body vessel to capture embolic debris entrained in the fluid of the vessel. The expandable frame and filtering element can be mounted on a filter support structure, such as a coiled wire, and mounted on a guide wire. The expandable frames includes an articulation region which helps to distribute the strain which can be developed when the frame moves between an expanded and deployed position. The expandable frame may include further strain distributing bends which help distribute strain and increase the bendability of the frame.

摘要: An apparatus is usable for guiding and stabilizing a body implantable medical device. The apparatus includes a guide wire with an enlarged distal tip. The enlarged distal tip may include a compliant portion to prevent tissue abrasion or perforation. The implantable device includes an open lumen configured to longitudinally advance along the guide wire. A sleeve is disposed over the guide wire and slidably deployable over the enlarged tip of the guide wire. When the implantable device is in final position, the open lumen encompasses at least part of the enlarged tip of the guide wire. The sleeve can be moved over at least part of the enlarged tip and create an interference between the tip and the open lumen, thereby stabilizing the implantable device.

摘要: Assessing Susceptibility to Epilepsy and Epileptic Seizures A method and system adapted to assist with assessing susceptibility to epilepsy and/or epileptic seizures in a patient receives (202) patient brain data and generates (204) a network model from the received patient brain data. The system further generates (206) synthetic brain activity data in at least some of the nodes of the network model and computes (208) seizure frequency from the synthetic brain activity data by monitoring transitions from non-seizure states to seizures states in at least some of the nodes over time. The system further includes a device (104, 110) configured to use the seizure frequency to compute (210) a likelihood of susceptibility to epilepsy and/or epileptic seizures in the patient, and a device (104, 110) configured to compare (212) the computed likelihood with another likelihood of susceptibility to epilepsy and/or epileptic seizures in order to assess whether the likelihood has increased or decreased.

摘要: This invention relates to a solid oxide fuel cell system comprising at least one longitudinally extending tubular solid oxide fuel cell and a longitudinally extending heater mounted in thermal proximity to the fuel cell to provide heat to the fuel cell during start up and during operation as needed. The heater and fuel cell can be encased within a tubular thermal casing; the inside of the casing defines a first reactant chamber for containing a first reactant, such as oxidant. The fuel cell comprises a ceramic solid state electrolyte layer and inner and outer electrode layers concentrically arranged around and sandwiching the electrolyte layer. The outer electrode layer is fluidly communicable with the first reactant, and the inner electrode layer is fluidly isolated from the first reactant and fluidly communicable with a second reactant, such as fuel.
