  • Patent number: 11324547
    Abstract: Electrosurgical probes for treating tissue, and surgical procedures that make use of such probes. Such a probe includes a working element having a core member, a sheath secured to the working element, and a conductor disposed in a first internal longitudinal channel of the core member and having an active electrode coupled thereto. The sheath has a passage in which the core member is disposed, and the passage has an opening at a distal end of the sheath. The conductor is reciprocable within the sheath and adapted to carry a radio frequency current to and from the active electrode, which extends from the opening at the distal end of the sheath. An irrigation channel is defined by a second internal longitudinal channel of the core member. The electrosurgical probe is marked as disposable and not for reuse in a medical procedure performed on more than one patient.

  • Patent number: 9707112
    Abstract: A concentric tube catheter for positioning a polymeric urethral stent implementing resistance heating to make the stent malleable for insertion into a urinary tract. An inflatable bladder is mounted to one end of the concentric tube catheter with the stent positioned around the inflatable bladder. The concentric tube catheter charged with a quantity of fluid. A static pressure control assembly and a variable pressure control assembly are in fluid connection with the concentric tube catheter. The quantity of fluid is pressurized within the concentric tube catheter with the static pressure control assembly in order to expand the inflatable bladder. A heating control system is used to increase the temperature of the stent allowing to become more malleable. The variable pressure control assembly oscillates the quantity of fluid to distribute heat evenly to the inflatable bladder and therefore to the stent. As the inflatable bladder expands, the malleable stent also expands.

    Abstract: This disclosure is directed to a resilient interpositional arthroplasty implant for application into a knee joint to pad cartilage defects, cushion a joint, and replace or restore the articular surface, which may preserve joint integrity, reduce pain and improve function. The implant may endure variable joint compressive and shear forces and cyclic loads. The implant may repair, reconstruct, and regenerate joint anatomy, and thereby improve upon joint replacement alternatives. Rather than using periosteal harvesting for cell containment in joint resurfacing, the walls of this invention may capture, distribute and hold living cells until aggregation and hyaline cartilage regrowth occurs. The implant may be deployed into debrided joint spaces, molding and conforming to surrounding structures with sufficient stability to avoid extrusion or dislocation.

    Abstract: Provided is a surgical apparatus for transanal endoscopic microsurgery (TEM) in which a thin and long endoscope and surgical instruments are inserted through a natural orifice of a human body and the endoscope and surgical instruments are conveyed to the operation area in the body to perform the operation area in the body. According to the surgical apparatus for TEM, a rotation function is added to a barrel of the surgical apparatus for TEM to enable manual rotation of the barrel to a required extent and adjustment of an operation area, without separation of the surgical apparatus for TEM from a fixing frame during an operation. In addition, since the endoscope is disposed outside the barrel, it is possible to reduce the outer diameter of the barrel and uniformly maintain a visual direction of the endoscope even when the barrel is rotated. Further, since the rotation function is added to both the barrel and the surgical instrument insertion hole, more convenient operation is possible.

  • Patent number: 8159549
    Abstract: An in-vivo imaging device including a camera may include a frame storage device. Systems and methods which vary the frame capture rate of the camera and/or frame display rate of the display unit of in-vivo camera systems are discussed. The capture rate is varied based on physical measurements related to the motion of the camera. Alternatively, the frame capture rate is varied based on comparative image processing of a plurality of frames. The frame display rate of the system is varied based on comparative image processing of a multiplicity of frames. Both the frame capture and the frame display rates of such systems can be varied concurrently.

  • Patent number: 7894882
    Abstract: A miniature ingestible capsule has multiple therapeutic or diagnostic operations that can be performed. These functions are controlled by a combination of an outside control, a pose beacon and through information relayed from an imagining array and transmitter. These functions can be in a separate capsule without an imaging array or within the same capsule with an imaging array. Typically, there is one function performed in addition to imaging. These functions can include suction and spray capabilities, ultrasound sensor, lithotripsy, laser, heat, electrocautery, BICAP, biopsy forceps, a needle knife snare cautery (cold and hot with continuous or pulsed current for cutting and coagulation), with a basket, and fine needle aspiration with various wheels and fins and motors controlled externally and other tools to be used in humans. All of these tools can be attached to a retractable arm. Also, they can be used on an elevator device that lifts them, allowing for an extra 180° of movement.

  • Publication number: 20100331621
    Abstract: An improved bipolar resection device provides an intuitive finger grip control in a smaller sheath package. Bipolar electrode wires occupy less space by extending in a closely abutting relationship along the sheath and exiting in a one above the other orientation that provides a reduced profile, allowing for better visualization during resection. In various embodiments, resection motion is provided through a rotational sweep transverse to the longitudinal axis of the resection device and may include push/pull motion. The sheath may be oval in shape and the bipolar electrode connected to the bipolar electrode wires having a narrow cross-section to improve resection site visualization.

  • Publication number: 20100312053
    Abstract: A surgical instrument has a channel dimensioned to receive a viewing instrument and enable the viewing instrument to be moved to or from a position near an optically transparent portion of a blunt, enclosed distal end of a shaft to provide unobstructed viewing through the distal end, and a position to the proximal side of an enclosed working area to provide viewing of the enclosed working area. A surgical instrument also or alternatively has a fluid routing switch within a shaft which can selectively connect a fluid infusion channel to at least one fluid export pore or a return channel. A method involves moving a viewing instrument to or from a position near an optically transparent portion of a blunt, enclosed distal shaft end and a proximal side of an enclosed working area. A method also or alternatively involves changing a position of a fluid routing switch within the shaft.
