Apparatus for performing an electrosurgical procedure
A surgical instrument is provided and includes a housing having a shaft. An end effector assembly is operatively connected to a distal end of the shaft and has a pair of first and second jaw members that are movable relative to one another. A drive assembly operably couples to a handle assembly associated with the housing and is configured to impart movement of a respective jaw member when the handle assembly is actuated. A spring component operably associated with each of the jaw members is configured to provide a sealing force at the jaw members.
Apparatuses and methods for cutting a tissue bridge and/or removing a heart valve clip or suture
A medical device for safely and effectively removing a clip or a suture from a heart valve is operable in association with a guidewire for positioning the device in proximity to the heart valve. The apparatus may include a blade for cutting a tissue bridge including the clip and an arrangement for removing the tissue bridge from the heart valve. The apparatus may include two arms that secure the clip. The blade may be deployed to core out a central portion of a tissue bridge, including the clip or the suture, from the heart valve. The blade may be activated by an actuator. A retrieval member may be configured to capture the tissue bridge and the clip or suture after excision by the blade.
Flexible wrist-type element
A flexible wrist-type element, comprising: a base housing extending along a first longitudinal axis towards a base end; an operational housing extending along a second longitudinal axis towards an operational end; an operational element moveably connected to the operational housing; a joint assembly movably connecting the base housing and the operational housing; wherein the joint assembly allows relative movement of the operational housing and the base housing between a first position and a second position, wherein a point of intersection between the second longitudinal axis and the first longitudinal axis moves during movement between the first position and the second position; a driver assembly moveably supported by the base housing and the operational housing; and wherein the driver assembly is configured to actuate the operational element relative to the operational housing.
METHOD FOR BONE ADJUSTMENT WITH ANCHORING FUNCTION
A method and a device for bone adjustment in a mammal is presented, wherein a device is implanted in the medullar cavity of a bone in the body of said mammal, said device being a device exerting a force to anchoring devices anchored in said bone. The method and device has utility in therapeutic and cosmetic bone adjustments, including the lengthening, reshaping and realigning of bones, for example in the correction of congenital deformations, restorative orthopaedic surgery and the like.
Surgical platform with motorized arms for adjustable arm supports
A motorized arm for a robotic medical system can include a shoulder coupled to a column of a table by a translational joint that allows translation of the shoulder along the column, a first link rotationally coupled to the column, a second link rotational coupled to the first link, and an arm support coupled to a distal end of the second link. The arm support can be configured to support one or more robotic arms usable during a robotic medical procedures. The motorized arm can include actuators for driving rotation of the links and arbors that can be engaged to increase the torsional stiffness of the motorized arm. The motorized arm can move the arm support between a stowed position below the table to a deployed position.
ROBOTIC ASSISTER FOR CATHETER INSERTION
Apparatus for controlling motion of an invasive probe relative to a sheath enclosing the probe. The apparatus includes an outer casing, configured for connection to the sheath. The apparatus further includes a drive mechanism, fixedly connected to the outer casing. The drive mechanism has a first set of components, configured to translate the probe along a direction parallel to as axis of the probe, in order to advance and retract the probe with respect to the sheath in a translational stepwise manner. The drive mechanism also includes a second set of components, configured to rotate the probe around the axis of the probe, in order to rotate the probe clockwise and counter-clockwise, with respect to the sheath, in a rotational stepwise manner.
Hydraulic instrument drive system for minimally invasive surgery
A robotic surgical system includes a hydraulic drive system and a surgical instrument removably positioned in operative engagement with the hydraulic drive system.
Adjustable devices for treating arthritis of the knee
A method of changing a bone angle includes creating an osteotomy between a first portion and a second portion of a tibia of a patient; creating a cavity in the tibia by removing bone material along an axis extending in a substantially longitudinal direction from a first point at the tibial plateau to a second point; placing a non-invasively adjustable implant into the cavity, the non-invasively adjustable implant comprising an adjustable actuator having an outer housing and an inner shaft, telescopically disposed in the outer housing, and a driving element configured to be remotely operable to telescopically displace the inner shaft in relation to the outer housing; coupling one of the outer housing or the inner shaft to the first portion of the tibia; coupling the other of the outer housing or the inner shaft to the second portion of the tibia; and remotely operating the driving element to telescopically displace the inner shaft in relation to the outer housing, thus changing an angle between the first portion and second portion of the tibia.
CONTROL MECHANISM FOR END EFFECTORS AND METHOD OF USE
A medical device includes a shaft including a longitudinal axis, an end effector connected to a distal end of the shaft to move from a first orientation, where a longitudinal axis of the end effector is approximately parallel to the longitudinal axis of the shaft, to a second orientation, where an angle is formed between the longitudinal axis of the end effector and the longitudinal axis of the shaft, and an elongated member attached to a proximal end of the end effector, wherein manipulation of the elongated member moves the end effector between the first orientation and the second orientation.
OPERABLE IMPLANT
An operable implant adapted to be implanted in the body of a patient, the operable implant comprising an operation device and a body engaging portion, wherein the operation device comprises a first unit comprising a receiving unit for receiving wireless energy and a first gear system adapted to receive mechanical work having a first force and first velocity, and output mechanical work having a different second force and a different second velocity. The operation device further comprises a second unit comprising an electrical motor adapted to transform electrical energy to the mechanical work, and a distance element adapted to separate the first and second units such that the receiving unit, when receiving wireless energy, is not substantially affected by the second unit.
