  • Publication number: 20140303429
    Abstract: A system for supporting the urethra using an introducer needle, the ends of which are flattened and which have openings therethrough, a handle having a latch mechanism which engages the opening in the flattened portion of the first end of the introducer needle, an implant, and a connector joining the end of the implant to the flattened portion of one of the ends of the introducer needle. These components are used to draw the implant into position, either through vaginal or abdominal incisions, to form a U-shaped loop beneath the urethra. The ends of the implant are adjusted to provide proper support for the urethra. The implant can have slits that open under applied tensile force.

  • Patent number: 8845512
    Abstract: The present disclosure is generally directed to surgical articles useful for implanting support members in patients. The articles disclosed herein include a support member, such as a sling for urinary incontinence, tissue anchors, filamentary elements for associating the support member with the anchors, and introducer needles for placing the anchors in a patient. The support members can also be configured for use in pelvic floor repair, such as for treating cystoceles, rectoceles, and enteroceles.

  • Patent number: 8795364
    Abstract: A system for repairing a vertebral disc defect, such as hernia or bulge, a full or partial tear in the annulus, or a weakened annulus wall as a result of an excision procedure. The system introduces a treatment device arranged to repair the defect, and may prevent the leakage of fluid from the nucleus. The components of the device may be resorbable materials, and may induce the ingrowth of cellular material into the components. The system may feature a locating device to ensure proper placement of the treatment device.

  • Patent number: 8721626
    Abstract: In an embodiment, the invention provides a catheter suitable for use in performing a procedure within a vessel, lumen or organ of a living having a distal end which is steerable, such as upon the application of compression. The catheter may be of the over the wire type, or alternatively may be a rapid exchange catheter. The catheter may provide for a rotating element which may be used to open a clogged vessel, or alternatively to provide information about adjacent tissues, such as may be generated by imaging or guiding arrangements using tissue detection systems known in the art, e.g., ultrasound, optical coherence reflectometry, etc. For rapid exchange catheters having a rotating element, there is provided an offset drive assembly to allow the rotary force to be directed from alongside the guidewire to a location coaxial to and over the guidewire.

  • Patent number: 8623094
    Abstract: An implant for deployment in select locations or select tissue for regeneration of tissue is disclosed. The implant comprising collagen and or other bio-resorbable materials, where the implant may also be used for therapy delivery. Additionally, the implant may be “matched” to provide the implant with similar physical and/or chemical properties as the host tissue.

  • Publication number: 20130244856
    Abstract: Centrifuges are useful to, among other things, remove red blood cells from whole blood and retain platelets and other factors in a reduced volume of plasma. Platelet rich plasma (PRP) and or platelet poor plasma (PPP) can be obtained rapidly and is ready for immediate injection into the host. Embodiments may include valves, operated manually or automatically, to open ports that discharge the excess red blood cells and the excess plasma into separate receivers while retaining the platelets and other factors in the centrifuge chamber. High speeds used allow simple and small embodiments to be used at the patient's side during surgical procedures. The embodiments can also be used for the separation of liquids or slurries in other fields such as, for example, the separation of pigments or lubricants.

  • Patent number: 8377080
    Abstract: A system and method of use for effecting the bypass or other anastomosis, connection, or port in a portion of a native blood vessel, duct, lumen or other tubular organ within the body of a living being. The system includes a connector assembly and a deployment instrument for carrying the device to the desired position within the vessel, duct, lumen or tubular organ. The system includes a piercer-dilator instrument to form an opening in the wall of the vessel, duct, lumen or tubular organ into which a connector assembly may be deployed by the deployment instrument. The connector assembly may be at least partially formed of a resorbable material and includes movable members for securing it to the tissue of the vessel, duct, lumen or tubular organ contiguous with the opening. Other components may be included in the device for expediting the procedure, with or without the use of sutures.
