  • Patent number: 10874538
    Abstract: The present invention relates to a device for intermittently obstructing a bodily opening, such as a gastric opening, and includes a proximal member connected to a distal member by a tether. The proximal member is formable from an elongated and narrower configuration to a contracted or expanded but wider configuration. When employed in the stomach, the device may be arranged transluminally with the distal member disposed in the duodenum and the proximal member disposed against the pyloric valve, intermittently occluding the pyloric valve and preventing or delaying the flow of gastric contents through the pyloric valve.

  • Publication number: 20200272050
    Abstract: The present disclosure relates to novel negative-type photoresist composition and methods of their use. The disclosure further relates to multiple trigger photoresist processes which allow for the improvement in contrast, resolution, and/or line edges roughness in some systems without giving up sensitivity. The photoresist compositions and the methods of the current disclosure are ideal for fine patent processing using, for example, ultraviolet radiation, extreme ultraviolet radiation, beyond extreme ultraviolet radiation, X-rays and changed particle. The disclosure further relates to sensitivity enhancing materials useful in the disclosed compositions and methods.

  • Publication number: 20190137876
    Abstract: The present disclosure relates to novel multiple trigger monomer containing negative working photoresist compositions and processes. The processes involve removing acid-labile protecting groups from crosslinking functionalities in a first step and crosslinking the crosslinking functionality with an acid sensitive crosslinker in a second step. The incorporation of a multiple trigger pathway in the resist catalytic chain increases the chemical gradient in areas receiving a low dose of irradiation, effectively acting as a built in dose depend quencher-analog and thus enhancing chemical gradient and thus resolution, resolution blur and exposure latitude. The photoresist compositions utilize novel monomers and mixtures of novel monomers. The methods are ideal for fine pattern processing using, for example, ultraviolet radiation, beyond extreme ultraviolet radiation, extreme ultraviolet radiation, X-rays and charged particle rays.

  • Publication number: 20140235361
    Abstract: Torque shafts and other related systems and methods are described herein. The torque shafts are both flexible and capable of transmitting torque. The torque shafts are useful for procedures that require torque and pushability to drive or deploy a device. The flexibility and pushability of the torque shafts enable them to curve along a tortuous path, and the torque transferring capability of the shafts enable them to transmit torque along the shaft.

  • Publication number: 20080091078
    Abstract: A medical device for managing tissue in an organ, such as the stomach, for retracting or positioning tissue and related organs to allow certain regions of the stomach to be acquired for a gastroplasty procedure. The medical device includes an elongated body having a proximal end and a distal end, and a tissue treatment device attached to the distal end of the elongated body. The tissue treatment device includes a first jaw opposite a second jaw, and each jaw is adapted to acquire tissue. A retractor is disposed along the tissue treatment device and adapted to be moveable from a delivery position to a retraction position to move or manage the tissue of the stomach. The medical device also includes a collapsible barrier disposed between the first and second jaws of the tissue treatment device to direct tissue into the first and second jaws separately.

  • Publication number: 20070203552
    Abstract: Methods and apparatuses for temperature modification of a patient, or selected regions thereof, including an induced state of hypothermia. The temperature modification is accomplished using an in-dwelling heat exchange catheter within which a fluid heat exchange medium circulates. A heat exchange cassette of any one of several disclosed variations is attached to the circulatory conduits of the catheter, the heat exchange cassette being sized to engage a cavity within one of various described re-usable control units. The control units include a heater/cooler device, a user input device, and a processor connected to receive input from various sensors around the body and the system. The heater/cooler device may be thermoelectric to enable both heating and 15? cooling based on polarity. A temperature control scheme for ramping the body temperature up or down without overshoot is provided.
