  • Patent number: 8641609
    Abstract: A method of thermally treating tissue during a surgical procedure where a surgical access device, including a body member having walls with at least one conduit therein, is inserted into the patient. A chilled fluid is circulated through the at least one conduit such that the tissue that is located proximate the body member is cooled. Alternatively, the body member may be constructed from a highly thermally conductive material such that heat energy is transmitted through the body from the tissue located proximate the body member and into a heat sink. The surgical device may include a first or second blade portions constructed from an inner and an outer shell having walls. Ribs located on the inner shell sealingly coupled to the inner wall of the outer shell to create the at least one conduit within the walls of the blade portion.

  • Publication number: 20120146327
    Abstract: Adjustment of stresses within a threaded connection having radial thread interference is taught by forming the box and pin threads on different axial pitches before assembly, so as to result in a preferred stress pattern after assembly. Also taught, is how to shape thread forms so as to avoid galling while connecting or disconnecting the box and pin.

  • Patent number: 8083712
    Abstract: A flat-hose assembly has a proximal end and a distal end adapted for use with a negative pressure wound drainage system. The flat-hose assembly comprises a top layer, a bottom layer, and a filter layer. The bottom layer forms an opening at the distal end of the flat-hose assembly to allow exudates of a wound to flow into the flat-hose assembly. The filter layer is disposed between the top layer and the bottom layer. The top and bottom layer form a seal area along a periphery of the top layer and the bottom layer to seal the filter layer therebetween.

  • Patent number: 8034038
    Abstract: A portable closed wound drainage system that uses a pouch shaped dressing which is inserted into a wound. At least a portion of the outer surface of the pouch 1 is porous to allow exudates to enter. Exudates are removed from the pouch by flexible tubing which is secured inside the pouch at one end, and secured at the other end to a portable drain/suction unit. The pouch contains porous material, and may optionally contain beads and fillers which are antibacterial in nature. The tubing can have a single or multi-lumen structure with perforations in the side walls of the end of the tube that is inserted in the pouch to allow body fluids to enter laterally. The portable drain/suction unit is preferably a portable battery powered device. The pouch and the tube are sealed by a flexible sealing material which is applied to the outer surface of the skin around the periphery of the pouch and the tubing as it exits the pouch.

  • Patent number: 7842072
    Abstract: A device for spinal stabilization includes bone anchors, a metal cord, and a spacer. The materials of the cord and spacer are chosen to allow the physician to customize the stiffness of the stabilization device based on a particular patient's needs. Each bone anchor has a clamping mechanism for securing the cord to the bone anchor. In an assembled and implanted state of the device, the spacer is positioned between two neighboring bone anchors, thereby impeding the motion of the bone anchors toward each other; the cord is clamped to the bone anchors, thereby impeding the motion of the bone anchors away from each other. By increasing or decreasing the tension in the cord during implantation, the physician can create a stabilization device that is either relatively stiff or relatively flexible to accommodate the specific needs of the patient.

  • Publication number: 20100082323
    Abstract: Devices systems and methods are provided for providing a deterministic remote interface unit (RIU) based on a finite state machine. The RIU emulator uses a sequence controller that is configured to receive a synchronization input and to execute a fixed list of unconditional commands in an invariable order of execution based solely upon the synchronization input. The RIU emulator also uses pre-defined or pre-certified data structures that are specific to one or more interface devices to successfully execute the at least one unconditional command of the plurality when encountered in the invariable order. As such, peripheral devices may be added, removed or updated without recertification by merely inserting pre-certified data structures into memory or deleting them.
