    摘要: The invention relates to an implantable stomach prosthesis for surgically replacing or augmenting all or part of the antrum and/or pylorus of a stomach. The prosthesis controls the passage of food from the stomach to the small intestine. The prosthesis may be configured to churn ingested material and release it from the stomach through a prosthetic pyloric valve. At least one expandable member is arranged to be expanded to control the passage of food and/or to mimic the churning action of a patient's stomach. The prosthesis includes an outer support structure, a flexible inner member forming a conduit for the movement of material, and at least one expandable member located between the outer support structure and inner member. An implantable pump system is provided for inflating and deflating the expandable member(s).

    摘要: A method for diagnosing and treating gastric disorders is provided. A functional device resides within the patient?s stomach and is secured to the stomach wall by an attachment device. The functional device may be a sensor for sensing various parameters of the stomach or stomach environment, or may be a therapeutic delivery device. The functional device in one embodiment provides a method for gastric electrical stimulation where stimulating electrodes are secured to the wall of the stomach by the attachment device or otherwise. A preferred device includes: at least one stimulating electrode in electrical contact with the stomach wall; an electronics unit containing the electronic circuitry of the device; and an attachment mechanism for attaching the device to the stomach wall. The functional devices may be programmed to respond to sensed information or signals. An endoscopic delivery system delivers the functional device through the esophagus and into the stomach where it is attached the stomach wall. The endoscopic instruments attach or remove the attachment devices and functional devices from the stomach and may be used to assist in determining the optimal attachment location.

    摘要: Ultrasound apparatus for examining tissue in a region of interest in a body comprising a housing having a viewing aperture. An ultrasonic transducer is provided comprised of an array of ultrasonic elements disposed in the viewing aperture. Electrical pulses are supplied to the transducer for transducer excitation to introduce ultrasonic signals into the body for reflection from the tissue in the region of interest. The transducer is capable of converting ultrasonic signals reflected from the tissue within the body to the transducer to provide electrical signals. The electrical signals are gain corrected in accordance with time. In-phase and out-of-phase components of the electrical signals are provided and then digitized. The digitized electrical signals are collected to form one image for a single frame of the tissue in the region of interest in the body from transducer excitations less than thirty-three in number which is then displayed.
