  • Patent number: 8231579
    Abstract: A cannula sealing apparatus includes a housing having a central axially facing aperture. A surgical instrument of 10.5 mm may seal with that aperture. Alternatively, a sealing member having an aperture that will seal with a 12 mm surgical instrument can be swung up to be aligned with the aperture. If a 10.5 mm instrument is required then a seal member can be swung up to have its seal aperture located over the central aperture. Each seal member is pivotal about a common axis.

  • Patent number: 8231583
    Abstract: A blood collection assembly includes a needle cannula, a hub mounted on the needle cannula, and a spring biased pivoting shield pivotably mounted to the hub and moveable about a pivot axis between a retracted position and a shielded position encompassing a distal end of the needle cannula. A needle holder is mated at a first end with the hub, and is adapted for receiving a blood collection container such as an evacuated tube through the opposing end. A retaining member is attached to the pivoting shield and is releasably engageable with the hub to maintain the pivoting shield in the retracted position against the spring bias. Insertion of a blood collection tube into the needle holder causes the retaining member to release from engagement with the hub, thereby causing the pivoting shield to move toward the shielded position due to the spring bias.

  • Patent number: 8231601
    Abstract: A long catheter can be inserted into a patient while eliminating the need for a sterile field by incorporating the long catheter into an infusion tubing and carrying it in with the infusion. The long catheter has a structure that prevents it from leaving the infusion tubing when fully extended and therefore becomes a connector for fluids to transfer down the long catheter by infusion through the infusion tubing. Use of an adjustable seat connector allows the long catheter to be stopped at varying points during insertion and even to allow the long catheter to be reversed by pulling suction on the infusion tubing and retracting the long catheter back into the infusion tubing. The long catheter also remains within the sterile confines of the infusion tubing and therefore is prevented from becoming contaminated.

  • Patent number: 8231617
    Abstract: A radio-frequency thermal balloon catheter includes a catheter tube including an outer tube and an inner tube, a balloon connected to an end part of the outer tube and an end part of the inner tube, and capable of coming into contact with a target diseased part when inflated, a radio-frequency electrode placed in the wall of the balloon or inside the balloon to transmit radio-frequency current, a lead wire electrically connected to the radio-frequency electrode, a temperature sensor capable of measuring temperature inside the balloon, and a swirling current producing means for making a fluid contained in the balloon swirl in a vertical plane in the balloon so as to reduce an upper-lower temperature difference between an upper part and a lower part of the interior of the balloon due to convection of the fluid to naught.

  • Patent number: 8231619
    Abstract: Sterilization devices and methods for deploying porous implants within the fallopian tubes are disclosed. The devices include a catheter component including an external electrode sheath containing at least two deployable implants and a positioning member. Sliding the external sheath proximally disposes the implants within the fallopian tubes, while sliding both the positioning member and external electrode sheath distally reloads a second implant into the external electrode sheath. The devices further includes a handle component, which houses a chassis, external electrode sheath carrier, reciprocating shaft, positioning member carrier and first and second engaging members. The reciprocating shaft may be operated by a motor to slide distally and proximally along a long axis. The reciprocating shaft, external electrode sheath and its carrier, upon selective actuation, move together proportionally to deploy and reload the implants to facilitate occlusion of the fallopian tubes and complete sterilization.

  • Patent number: 8231621
    Abstract: The present invention provides an apparatus for, and a method of, accurate positioning of endoscopic instruments. Accurate positioning of the instruments is accomplished through the inclusion of a steering ability within the device. After the endoscopic instrument is properly positioned, the present invention may use rapid exchange technology, soft locks, and mechanical locks to maintain the position of the endoscopic instrument. Rapid exchange technology is used to minimize displacement forces present on the guidewire or catheters. Soft locks and mechanical locks resist movements caused by displacement forces.

  • Patent number: 8231622
    Abstract: The invention relates to a bipolar coagulation instrument having a hollow shaft configured as a suction and/or flushing tube and having two electrodes that are electrically insulated with respect to one another and extend beyond the distal end of the shaft. To provide a bipolar coagulation instrument that is both of simple structure and ensures an effective suction/flushing capacity, it is proposed with the invention that the hollow shaft should consist of two electrically conductive tubes coaxially mounted on one another that are electrically insulated with respect to one another and from the outside, so that the tubes constitute the electrodes.

  • Patent number: 8231623
    Abstract: A pair of clamps are attached to a damaged bone one each side of a fracture site during a surgical reduction, one clamp on each side of the fracture site, after which the two clamps are slidably engaged to a single pivotal alignment bar, with the clamps then being adjusted to properly align the bone for a surgical attachment using a bone plate which is secured between the respective bone and each respective clamp, holding the bone in place with the bone in proper alignment for the attachment of screws through the plate into the bone, stabilizing the fracture site during the plate attachment procedure.

  • Patent number: 8231624
    Abstract: A surgical implant device capable of conforming to a variety of surface topographies facilitates the growth and regeneration of site to which the device is applied. The device employs a plurality of elongate members supporting a column of discrete, rotatable elements in contact with each adjacent element. Anchor plates secure the respective ends of the elongate members, such anchor plates attachable to bone. The implant device provides and ordered array of individually rotatable elements to form a surface that permits bodily fluids to pass therethough.
