Принадлежит: Paulos Lonnie E

A suture anchor assembly and methods of use will now are disclosed for the repair of human or animal tissue defects. The suture anchor assembly is capable of being inserted into a tissue or bone while also being able to create an expanded profile when subjected to a retrograde force. This expanded profile anchors the assembly into the tissue or bone by a changing of position of elements of the assembly relative to other assembly elements. Embodiments of the suture anchor assembly and methods are capable of precisely positioning assembly elements in the tissue or bone to effectively repair the defects.

Автор: Parviz Kambin, Sheila P. Kambin
Принадлежит: Individual

In endoscopic surgery, a retractor having independently spreadable retractor blades mounted at the distal end of a tube is introduced percutaneously. A balloon dissector is passed through the tube and expanded. Following dissection by expansion of the balloon, the balloon is contracted, the tube is advanced, and the dissected tissue is spread by moving the blades apart from each other. The balloon dissector is withdrawn and another instrument is then introduced to carry out surgery on the anatomical structure exposed by the dissection and spreading steps.

A device for immobilizing a patient for a medical test or operation includes a molding element that is convertible from a flexible, elastic form to a rigid form by the application of a vacuum. The molding element is attached to the patient by an elastic layer while in the flexible, elastic form where it conforms to the contours of the patient's body. Then the molding element is converted to its rigid form thereby immobilizing the patient. Auxiliary devices can be attached to the immobilizing device and these devices, such as a pivot arm suspension can be used to fix the immobilized patient to an operating table.

Knotless graft fixation using an implant having a pointed tip

Номер: US20130150885A1
Автор: Peter J. Dreyfuss
Принадлежит: Arthrex Inc

A method for securing soft tissue to bone which does not require the surgeon to tie suture knots to secure the tissue to the bone. Suture is passed through the graft at desired points. A cannulated plug or screw is pre-loaded onto the distal end of a driver provided with an eyelet implant at its distal end. Suture attached to the graft is passed through the eyelet of the implant located at the distal end of the driver. The distal end of the driver together with the eyelet implant is inserted into the bone. Tension is applied to the suture to position the graft at the desired location relative to the bone. The screw or plug is advanced into the pilot hole by turning the interference screw or tapping the plug until the cannulated screw or plug securely engages and locks in the eyelet implant, so that the cannulated plug or screw with the engaged eyelet implant is flush with the bone. Once the screw or plug is fully inserted and the suture is impacted into the bone, the driver is removed and any loose ends of the sutures protruding from the anchor site are then clipped short.

The present invention relates to devices and methods for the treatment of diseases in the vasculature, and more specifically, devices and methods for treatment of aneurysms found in blood vessels. In a first embodiment of the present invention, a two part prostheses, where one part is an expandable sponge structure and the other part is an expandable tubular mesh structure, is provided. In the first embodiment, the expandable sponge structure is intended to fill the aneurysm cavity to prevent further dilatation of the vessel wall by creating a buffer or barrier between the pressurized pulsating blood flow and the thinning vessel wall. In the first embodiment, the expandable tubular mesh structure is placed across the aneurysm, contacting the inner wall of healthy vessel proximal and distal to the aneurysm.

An applicator insertable into a living body includes a nozzle having an elongated nozzle main body and a nozzle head on a front end side of the nozzle main body and through which liquid together with gas is expelled, with the nozzle main body including a flexible curved section. The applicator also includes an outer tube in which is positioned a portion of the nozzle main body so as to be movable along a longitudinal direction. The angle or degree of curvature of the curved section is changed by inserting the curved section into the outer tube to thereby adjust the direction of the nozzle head relative to the axis of the nozzle main body. In addition, a longitudinally extending gap exists between the outer tube and the nozzle. The gap functions as a discharge path for discharging the gas within the body cavity.

Thermal, Electrosurgical and Mechanical modalities may be combined in a surgical tool. Potentially damaging effects in a first modality may be minimized by using a secondary modality. In one example, thermal hemostasis may thus help electrosurgical applications avoid the adverse tissue effects associated with hemostatic monopolar electrosurgical waveforms while retaining the benefits of using incising waveforms.
