  • Patent number: 8491525
    Abstract: A needleless fluid delivery system for delivering therapeutic fluids to treatment sites within a patient. The fluid delivery system can include an automated injector source and a needleless access device. The access device can include a delivery scope and a treatment specific applicator. The automated injector source, delivery scope and applicator can be operably coupled with quick-connect style fittings so as to allow for quick replacement and maintenance of used or damaged components. The automated injector source can include a hands-free input mechanism allowing a medical professional to use both hands in manipulating the delivery scope and needleless applicator at the same time an injection is desired. The delivery scope and needleless applicator can comprise flexible or rigid lengths of tubing based on the accessibility of the treatment site. The needleless delivery system can include an imaging system for precisely position the applicator with respect to the treatment location.

  • Patent number: 8425540
    Abstract: A surgical tool including an elongated body having a proximal end and a distal end, first and second sets of tissue approximating structures having deployed and retracted positions relative to the elongated body, an actuating mechanism at the proximal end of the elongated body for independently deploying and retracting each of the first and second sets of tissue approximating structures, and a drainage lumen extending from a drainage aperture at the distal end of the elongated body to the proximal end. The tool further includes a main balloon adjacent to the distal end of the elongated body, and a second balloon spaced from the main balloon toward the proximal end of the elongated body, wherein the second balloon has an expanded condition in which it diverts one of the set of tissue approximating structures away from the main balloon.

    Abstract: A needleless fluid injection device including a flexible shaft with a proximal end, a distal end, an injection lumen extending from the proximal end to the distal end of the shaft, and at least one injection orifice extending through a wall of the injection lumen at the distal end of the shaft. The injection lumen can include a depth-limiting system (462) at its distal end for controlling the depth of insertion of the injection lumen relative to a target tissue of a patient. The injection lumen can alternatively or additionally include at least one guidance feature. The injection lumen can alternatively or additionally include at least one flow-modifying protrusion extending from the inner tubular wall of the injection lumen and toward a longitudinal axis of the injection lumen.

  • Patent number: 8066725
    Abstract: An anastomosis device providing increased functionality, reliability and safety through the use of designs addressing potential puncture of an inflation balloon being used to hold and approximate tissue. The anastomosis device can include bladder retention structures configured to engage and retain tissue without pointed or sharpened surfaces that can rupture the inflation balloon. The anastomosis device can include a reinforced or otherwise protected inflation balloon to resist puncturing by a bladder retention structure. The anastomosis device can include a catheter wall profile selected to physically prevent bladder retention structures from being forcibly bent back so as to avoid potential contact with and puncture of the inflation balloon. The anastomosis device can include a catheter funnel with an internal spring for preventing kinking of the catheter lumen while providing for flexibility and stretch of the funnel to absorb pulling or shock force which can rupture the inflation balloon.
