A self-closing device for implantation within a patient's body includes base material including an inner surface area for securing the base material to a tissue structure, and a plurality of support elements surrounding or embedded in the base material. The support elements are separable to accommodate creating an opening through the base material for receiving one or more instruments through the base material, and biased to return towards a relaxed state for self-closing the opening after removing the one or more instruments. The device may be provided as a patch, cuff, or integrally attached to a tubular graft or in various shapes.

An end effector assembly includes first and second jaw members movable between an open and closed position to grasp tissue therebetween. First and second proximal flanges extending proximally from the second jaw member and defining a space therebetween, a proximal flange extend proximally from a proximal portion of the first jaw member and define a cam slot. A cam driver operably is coupled to the proximal flange of the first jaw member to define a space between the cam driver and the proximal flange of the first jaw member. A cam bar is disposed within the space defined between the cam driver and the proximal flange of the first jaw member. The cam bar includes a cam pin configured to move within a cam slot of the cam driver to move the first jaw member relative to the second jaw member between the open position and the closed position.

Medical devices and methods for making and using medical devices are disclosed. An example medical device may include an elongate shaft having a proximal end region and a distal end region. A first lumen may be defined in the shaft. A second lumen may be defined in the shaft. The distal end region may include a common lumen region in fluid communication with the first lumen and the second lumen. A deflectable member may be disposed within the shaft. The deflectable member may be designed to shift between a first configuration where the deflectable member directs a first medical device disposed within the common lumen region into the first lumen and a second configuration where the deflectable member allows a second medical device to move between the common lumen region and the second lumen.

The present invention relates to implantable medical devices (dental and orthopedic) (osseointegrable implants) textured by the additive manufacturing process. Such implants are prepared in such a way as to comprise a larger surface area of contact between implant/adjacent tissues, porous microstructure with complex geometry with controlled and diversified pore size, which confers several technical advantages. In addition, the present invention relates to the process of preparing said implants and/or screws with an optimized structure for accelerating osseointegration. Finally, the present invention refers to the use of said implants as carriers of drugs or cells in order to treat the site, promote its healing, tissue regeneration or promote cell growth.

A concept for reliable and simple connection of a heat-resistant end piece (17) to a hose body (18) is described, and particularly a multiple lumen hose body (18). The connection technique is simple and reliable and leads to high quality probes having a long lifetime.

An integrated electrode structure can comprise a catheter shaft comprising a proximal end and a distal end, the catheter shaft defining a catheter shaft longitudinal axis. A flexible tip portion can be located adjacent to the distal end of the catheter shaft, the flexible tip portion comprising a flexible framework. A plurality of microelectrodes can be disposed on the flexible framework and can form a flexible array of microelectrodes adapted to conform to tissue. A plurality of conductive traces can be disposed on the flexible framework, each of the plurality of conductive traces can be electrically coupled with a respective one of the plurality of microelectrodes.

A number of orthopaedic surgical instruments are disclosed. A method, apparatus, and system for fabricating such instruments are also disclosed.

A system for rod bending for use in robotic spinal surgery, enabling the correct bending of a fusion rod to match the shape required to accurately pass through the heads of the pedicle screws. The system uses data generated by information provided to the robot by the surgeon's preoperative plan, optionally augmented by feedback from the robot control system of deviations encountered intraoperatively. Such deviations could occur, for example, when the surgeon decides intraoperatively on a different trajectory or even to skip screws on one vertebra, in which case, the robot will be commanded to perform the alternative procedure, with commensurate instructions relayed to the control system of the rod-bending machine. The system is also able to thin down the rod at predetermined locations along its length, adapted to be at selected intervertebral locations, for maintaining limited flexibility between vertebrae, instead of fixating them.

A vessel sealing device having a pair of electrodes that are maintained in spaced apart configuration when closed by non-uniform coating formed from a non-conductive material that has been applied to roughened electrodes so that the coating allows for the passage of a predetermined amount of radiofrequency (RF) energy between the electrodes. The coating has a predetermined thickness that spaces the electrodes apart while also having the predetermined non-uniformity that allows RF energy to pass between the electrodes when a vessel is trapped therein, thus desiccating the vessel positioned in the jaws. The electrodes may include a series of grooves in a herringbone pattern, with each electrode having the pattern oriented in the same direction or in opposite directions.

A surgical system includes a tubular shaft having a wall defining an outer surface and an inner surface disposed about an inner space, the tubular shaft having a proximal end and a distal end. The surgical system also includes at least one light emitter and at least one light sensor disposed at the distal end of the tubular shaft, and one or more leads or conductors electrically coupled to the at least one light emitter or the at least one light sensor. The one or more leads may be disposed in clearances defined by first and second jaws. Alternatively or in addition, the one or more conductors may be formed on a flexible substrate, and the flexible substrate may have a deformed state in which the substrate is disposed in the inner space.
