  • Publication number: 20070027461
    Abstract: A tissue connector assembly having a flexible member and a surgical clip releasably coupled to the flexible member. A needle may be secured to one end portion of the flexible member with the surgical clip coupled to the other end portion of the flexible member. A locking device may be used to couple the flexible member to the surgical clip. A method for connecting tissues is also disclosed. The method includes drawing tissue portions together with a clip assembly and securing the tissue portions together with the clip assembly.

  • Publication number: 20050245862
    Abstract: A torque mechanism for interventional catheters provides direct control over rotary positioning of the distal end of a catheter by rotating a proximal handle of the catheter. The torque mechanism comprises a stiff tube within and running the length of a flexible catheter body tube. The stiff tube is bonded at its distal end to the catheter body tubing and at its proximal end to a rotary handle. Catheter body tubing is bonded at its proximal end to a catheter hub. The catheter hub and rotary handle rotate independently, thus torque and position are transmitted by the torque tube while the catheter tube acts as a torsional spring.

  • Publication number: 20050004471
    Abstract: Methods and apparatus are provided for improved administration of brachytherapy in the treatment of prostate disease. More particularly, a prostate visualization device is provided comprising a catheter coupled to at least one deployable member at the distal end of the catheter. The deployable member is preferably manufactured from a shape memory alloy having a petal-shaped configuration suitable for engaging and defining the proximal region of a patient's bladder. The deployable member may comprise tubing filled with air or other radiopaque agents to facilitate ultrasonic imaging of the deployable members near the bladder/prostate junction.

  • Patent number: 6378218
    Abstract: Methods and apparatus are provided for converting standard catheters or balloon catheters into drug infusion devices on an as-needed basis in a sterile environment, and which permit re-use of catheter devices previously used in a preceding non-invasive procedure. Apparatus is provided having a cavity for receiving a catheter device and a plurality of perforation pins or teeth for creating apertures in the catheter. Apparatus capable of converting a wide range of catheter devices into drug infusion devices is provided, which apparatus may be single-use disposable or re-sterilizable and re-usable.

  • Patent number: 5055109
    Abstract: A torque transmitting assembly for guidewires, steerable fixed wire catheters and the like with a drive mechanism wherein the rotational output is greater than the rotational input. The assembly has a supporting structure with proximal and distal end pieces and a connecting arm or strut extending between and secured to the end pieces. An outer cylindrical shaped housing is rotatably mounted about the connecting arm and between the ends. A ring gear or other torque transmitting element is secured to the interior of the housing. A pinion gear or other torque transmitting element having a smaller diameter than the ring gear is rotatably mounted within support structure and the housing and is adapted to engage the ring gear in a torque transmitting relationship. The proximal end of a guidewire or the guiding element of a steerable catheter is secured to the pinion gear so that rotation thereof by the rotation of the housing causes a much greater the rotation of the attached guidewire or guiding element.

  • Patent number: 4907332
    Abstract: A device to facilitate the joining of a male proximal end of a guidewire to the female end of an extension wire. The device has a relatively flat body with a guiding groove in the upper surface with two aligned sections, the goove sections tapering inwardly toward the intersection thereof. One of the groove sections is adapted to receive the male end of the guidewire and one groove is adapted to receive the female end of the extension. One, preferably two, flexible tabs are secured to the upper surface of the body to maintain one of the ends within its respective groove section. The device and/or the connecting wires can be disengaged by the rotation thereof with respect to each other.
