20130015229 | Articulation and Firing Force Mechanisms - There is provided a surgical instrument incorporating driving force mechanisms capable of transmitting a driving force through an articulated section of the surgical instrument. In one embodiment, a series of racks connect with a transfer gear to pass forces around the articulated section. In an alternative embodiment a series of cable sections and wheels or pulleys are provided to transmit a driving force through the articulated section of the surgical instrument. | 01-17-2013 |
20130015233 | Tool Assembly for Surgical Stapling Device - The present disclosure describes a surgical device with a body portion defining a longitudinal axis, a tool assembly including an anvil, a cartridge assembly housing a plurality of staples, a dynamic clamping member movable relative to the tool assembly to eject the staples, and an articulation and firing actuator extending at least partially through the body portion and the tool assembly. The tool assembly is pivotally attached to the body portion for movement from a position aligned with the longitudinal axis to a position oriented at an angle thereto. The articulation and firing actuator extends at least partially through the body portion and the tool assembly, is operably associated with the dynamic clamping member and the tool assembly, and is movable in relation thereto to selectively pivot the tool assembly relative to the body portion and move the dynamic clamping member relative to the tool assembly to eject the staples. | 01-17-2013 |
20130018392 | MULTIPLE MEMBER INTERCONNECT FOR SURGICAL INSTRUMENT AND ABSORBABLE SCREW FASTENER - An absorbable screw fastener and a method of firing with an applicator capable of applying a surgical fastener to tissue in order to form tissue connection to secure objects to tissue, the fastener including a body portion having a helical thread, a head portion disposed at the proximal end of the body portion. The head portion includes a driver receiving configuration on its outer surface. The screw fastener further includes a cannulated center lumen with an opening extending from the head portion through the longitudinal length of the body portion. | 01-17-2013 |
20130018397 | MATERIAL REMOVAL DEVICE HAVING IMPROVED MATERIAL CAPTURE EFFICIENCY AND METHODS OF USE - The present invention provides an improved atherectomy catheter having means for directing particles generated by a cutting element into a collection chamber. Methods of directing the cut material from a blood vessel lumen into a collection chamber are also provided. | 01-17-2013 |
20130020012 | Welded Knot End Effector - An apparatus for forming an end effector includes a welding device having a welder positioned adjacent to a base, and a die coupled to one end of the welder. The base and the welder are movable relative to each other. The welder, base or die includes a source of heat that is applied to a portion of the suture disposed between the welder and the base. | 01-24-2013 |
20130020374 | Surgical Fastener Applying Apparatus with Controlled Beam Deflection - A surgical fastener applying apparatus including an anvil half-section having a distal end and a longitudinal axis; a cartridge receiving half-section having a distal end and operatively couplable with the anvil half-section such that the distal ends of the half-sections are in juxtaposed relation; and a deflection control system operatively engaged with and reinforcing the distal end of the anvil half-section when a force is applied to the distal end of the anvil half-section in a direction transverse to the longitudinal axis. | 01-24-2013 |
20130023869 | Electrosurgical Apparatus With High Speed Energy Recovery - A circuit for controlling the discharging of stored energy in an electrosurgical generator includes a pulse modulator which controls an output of a power supply. At least one comparator is configured to provide an error signal to the pulse modulator based on a comparison between an output signal generated by the power supply and a feedback signal generated in response to the application of energy to tissue. A discharge circuit is configured to control the discharge of the output of the power supply to an inductive load disposed in parallel with the output of the power supply based on the comparison between the output signal and the feedback signal. The discharge circuit provides a rapid response and time rate control of the delivered electrosurgical energy by controlling the power supply and delivered RF energy in real time, based on a feedback signal generated in response to the application of energy to tissue. | 01-24-2013 |
20130035668 | CLOSABLE MALE LUER CONNECTOR - A male luer connector is disclosed, the male luer connector being attached to a first tube and connectable to a female luer connector for providing a flow channel from said first tube to said female luer connector. The male luer connector includes a male luer part, which includes a tapered outer peripheral wall, a side wall, and an outlet opening. A tube member is also provided, the tube member having a flow channel therein. The tube member has openings at first and second ends thereof, the first end being movably inserted into an inner space of the side wall and the second end being connected to the first tube. The tube member further includes a male luer part sealing arrangement for sealing the outlet opening. | 02-07-2013 |
20130035688 | Apparatus, System, and Method for Performing an Electrosurgical Procedure - A bipolar forceps includes a shaft extending from a housing and includes an end effector assembly at its distal end. The end effector assembly has a pair of jaw members movable between an open position and a closed position. A knife assembly includes a cutter having a generally circular cross-section. The cutter is configured to cut tissue when the jaw members are in the closed position. One or more electrically conductive tissue sealing plates are disposed on each of the jaw members. The tissue sealing plates are adapted to connect to an electrosurgical energy source configured to deliver electrosurgical energy to tissue held between the jaw members to effect a tissue seal. An actuator is operably coupled to the knife assembly and is configured to selectively reciprocate the cutter relative to the jaw members. | 02-07-2013 |
