    摘要: A balloon catheter includes a flexible small-diameter guide wire provided with an enlarged-diameter distal end portion, and a flexible elongated tubular shaft with at least one dual-function fluid-conducting lumen adapted to both receive the guide wire extending therethrough, and to communicate pressurized inflation fluid to a distal balloon of the catheter. A distal orifice of the catheter communicates with the balloon and is provided with selective valving means for releasably engaging sealingly with the enlarged distal end portion of the guide wire. Apparatus is disclosed for axially moving the guide wire to effect engagement and disengagement of the enlarged distal end portion with the selective valving means of the catheter shaft. A torquer device is also provided by means of which the guide wire may be rotated relative to the catheter shaft for steering of the guide wire along a vascular pathway. A distal end tapered portion of the catheter shaft provides protection for a joint of the guide wire assembly. The tubular shaft of the catheter may extend through the balloon to provide better pushability for the catheter, especially in versions which employ a comparatively limp material for the balloon. Several alternative constructions for the selective valving means of the catheter shaft and for the enlarged distal end portion of the guide wire assembly are presented.

    摘要: An intramedullary lengthening device includes a housing and a distraction shaft. The intramedullary lengthening device is placed within a cavity of two bone sections (either already separated or purposely separated for insertion of the device). The distraction shaft of the intramedullary lengthening device is attached to the one of the bone sections using, for example, one or more attachment screws. The housing of the intramedullary lengthening device is attached to the second bone section using, for instance, one or more attachment screws. Over the treatment period, the bone is continually distracted, creating a new separation into which osteogenesis can occur. In one embodiment, the intramedullary lengthening device includes an actuator and an extension rod, which can be attached to one other.

    摘要: An ultrasound catheter is described herein for insertion into a cavity such as a blood vessel to facilitate imaging within a vasculature. The catheter comprises an elongate flexible shaft, a capacitive microfabricated ultrasonic transducer, and a sonic reflector. The elongate flexible shaft has a proximate end and a distal end. A capacitive microfabricated ultrasonic transducer (cMUT) is mounted to the shaft near the distal end. The reflector is positioned such that a reflective surface redirects ultrasonic waves to and from the transducer. In other embodiments, the catheter comprises a plurality of cMUT elements and operates without the use of reflectors. In further embodiments, integrated circuitry is incorporated into the design.

    摘要: A gastrointestinal implant system includes an adjustable restriction device having a contact surface configured for at least partially engaging a surface of a gastrointestinal tract of a mammal. The implant system further includes an implantable interface including a first driving element, the first driving element being moveable and operatively coupled to the adjustable restriction device by an actuator configured to change the dimension or configuration of the contact surface in response to movement of the first driving element. The system also includes an external adjustment device having a second driving element configured to non-invasively engage the first driving element of the implantable interface from a location external to the mammal. In the system, actuation of the second driving element of the external adjustment device produces movement in the first driving element of the implantable interface and results in a change in the dimension or configuration of the contact surface.

    摘要: Methods and apparatus useful for monitoring fluid flow past a gastric restriction device using noninvasive means are described. Some methods involve the use of acoustic energy, e.g., Doppler ultrasound, to monitor the passage of fluid past the restriction device, and apparatus to detect the acoustic energy. In some embodiments the method detects a sound-producing fluid using a microphone, stethoscope, or ultrasound probe and detector combination. In some embodiments, there are described methods of using Doppler ultrasound to monitor the flow of a fluid through a stomal opening, allowing a flow condition, e.g., a flow rate, to be determined, so that a physician can accurately adjust the gastric restriction device.
