  • Patent number: 9706900
    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: 9675759
    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: 9549799
    Abstract: Surgical procedures, kits and implants for alleviating human incontinence, and particularly providing improved methods and apparatus to secure a urethral sling (30) to pubic bone (24, 26) to support the urethra and alleviate incontinence are disclosed. Bone anchors (64) are driven into pubic bones with elongated bone anchor sutures (84) configured to be passed through openings of a urethral sling. Suture retainers are applied to the sutures to apply retentive force to the urethral sling to maintain the fixation of the urethral sling proximate to the pubic bone.

  • Patent number: 8864650
    Abstract: Surgical procedures, kits and implants for alleviating human incontinence, and particularly providing improved methods and apparatus to secure a urethral sling to pubic bone in a sub-urethral location to support the urethra and alleviate incontinence are disclosed. Bone anchors, e.g., bone screws, are driven into pubic bones with exposed bone anchor heads and necks configured to receive and support a urethral sling applied to the bone anchors with and without retainers applied against the urethral sling to retain portions of the urethral sling between the bone anchor heads and the pubic bones.
