20090005777 | ARTERIOTOMY CLOSURE DEVICES AND TECHNIQUES - A vascular closure system includes a vessel closure device with an electrically conductive component. The vessel closure device is configured to be advanced percutaneously to an opening in a blood vessel and to mechanically draw together sides of the opening or occlude the opening. A power source in electrical contact with the vessel closure device provides power to the vessel closure device to thereby heat tissue in an area near the opening to facilitate the closure or healing of the opening. The vessel closure device may be configured to be advanced to the opening over a tubular medical device. The vessel closure device may include a superelastic or shape memory element. The vessel closure device may be in contact with two conductors from the power source and may be configured to heat tissue via direct resistive element heating. Alternatively, one conductor may be connected to the vessel closure device and a second conductor may be connected to a ground pad on the patient. | 01-01-2009 |
20090054970 | Methods and Devices for Coupling a Device Insertable within a Mammalian Body - Methods and devices for a coupler adapted and configured for use with a device insertable within a mammalian body are disclosed. The devices comprise, for example, an elongate member having a lumen therethrough; and a flange extending from the elongate member at a first end further comprising a tissue engaging surface; an opening along a length of the elongate member having a width less than a diameter of the insertable device and adapted and configured to engage the insertable device within the lumen of the elongate member. | 02-26-2009 |
20090143789 | VASCULAR CLOSURE DEVICES, SYSTEMS, AND METHODS OF USE - A tissue closure system can include a deployment instrument and a sealing element. The deployment instrument can be slidably mounted to and guided by a tubular medical device. The deployment instrument can be advanced over the tubular medical device to the desired location. The sealing element can then be advanced off of the end of the tool. The sealing element can include tissue engaging elements that are configured to automatically close upon deployment to bring together tissue. A slidably attached guided skin (or other tissue) cutter can also be used if desired to facilitate entry of the deployment instrument. | 06-04-2009 |
20090143808 | Guided Tissue Cutting Device, Method of Use and Kits Therefor - The present invention relates to a guided tissue cutter configured to receive a cutter adapted to cut a target, and an elongate channel along the length of the tissue cutter adaptable to slide or rotate along or around an elongate member, The elongate member can be a medical device. The tissue cutter can comprise one or more stop members that permit the cutter to penetrate a predetermined region of a target tissue to a predetermined depth and to inhibit further penetration of a tissue beyond the predetermined region of the target tissue. The tissue cutter can be configured to clip or snap on and off of the elongate member. | 06-04-2009 |
20100211057 | TISSUE HEATING DEVICE AND RF HEATING METHOD WITH TISSUE ATTACHMENT FEATURE - A tissue cutting device includes a catheter with a window at its distal tip for admitting tissue into a catheter compartment. A cylindrical cartridge in the compartment has a cutting edge that supports an electrically conductive cutting element, e.g. a band or wire. The cutting element and adjacent tissue can be heated to a selected temperature by generating an electrical current through the cutting element. The catheter is maneuverable to position its distal end near the tissue to be cut. The catheter incorporates a dilatation balloon or other feature to urge the catheter against the tissue, so that at least part of the tissue may enter the compartment through the window. Then, the cartridge is manipulated from the catheter's proximal end to move the cutting edge across the window, cutting the tissue. According to alternative embodiments, the cartridge is either rotated or moved axially relative to the catheter and, in either event may be capable of closing the catheter window when the cut is complete. Further alternatives involve either placing an indifferent electrode on the patient and providing an RF signal via a single conductor to the cutting element for ohmic heating, or providing an RF (or a DC) current through the cutting element and two separate conductors for direct resistive heating of the cutting element. | 08-19-2010 |

20120038184 | ATHLETIC DEVICES AND OTHER DEVICES WITH SUPEREALSTIC COMPONENTS - Devices may contain superelastic components that are capable of producing a spring force in response to a deflection. A component for a motorized vehicle can include a deflectable wing formed of a superelastic material, wherein at least a portion of the deflectable wing is moved to a deflected position upon application of a threshold force when traveling at or above a predetermined speed, and returning to an undeflected position when traveling below the predetermined speed. The deflector may comprise a connection link fabricated from a superelastic material to tailor its flex point characteristics to a desired response in order to maintain the aerodynamic stability of the deflector when exposed to changing external forces. The superelastic components may improve the performance of such devices by improving aerodynamic properties. | 02-16-2012 |
20120319429 | MOTORIZED VEHICLES WITH DEFLECTABLE COMPONENTS - A deflectable component for a motorized vehicle can include a deflectable part formed at least partially from a superelastic and or shape memory material, wherein at least a portion of the deflectable component is moved to a deflected position upon application of a threshold force when moving at or above a predetermined speed, and returning to an undeflected position when moving below the predetermined speed. The deflectable component may comprise a connection link fabricated at least partially from a superelastic and/or shape memory material to tailor the flex point characteristics of a connected surface to a desired response. The deflectable component may improve the performance of motorized vehicles by improving the aerodynamic and fuel efficiency, as well as other beneficial effects. | 12-20-2012 |
20130053784 | METHODS AND DEVICES FOR SUTURELESS COUPLING OF A DEVICE INSERTABLE WITHIN A MAMMALIAN BODY, WITH ANCHORING, STABILIZATION AND INTEGRATED STRAIN RELIEF FEATURES - Methods and devices for a coupler adapted and configured for use with a device insertable within a mammalian body are disclosed.
