A disposable surgical instrument includes an instrument grip forming a receiving housing. A separate handle is mounted in the instrument grip in the manner of a rocker. A shaft tool includes a shaft having at least two relatively axially movable bar or rod components and an instrument head having patient engagement elements which can be actuated by the bar or rod components, of which one bar or rod component is fixed at the proximal end thereof to the instrument grip and the other bar or rod component has an articulation point on which the handle is directly articulated in such way that a manually actuated rocker movement of the handle about the articulation point on the handle side is transformed directly into an axial movement of the other bar or rod component on the articulation point on the shaft side.

The present disclosure provides an access system having a maneuverable catheter assembly configured for providing access to and navigating a desired vessel for subsequent treatment thereof. The access system includes an adjustable delivery handle assembly and an access catheter subassembly having a maneuverable access catheter configured to be delivered to desired site (e.g., within duodenum) to assist in treatment of a condition (e.g., drainage of a bile ducts via Endoscopic Ultrasound Guided Biliary Drainage (EUS-BD) techniques). The access catheter includes at least a distal section having an adjustable portion along a length thereof configured to transition to a pre-defined arcuate shape to provide directional control over the distal end of the catheter as it is navigated through a vessel (e.g., bile duct). The handle assembly includes additional elements configured to allow a clinician to maneuver and manipulate the distal end of the access catheter.

A device may include a sheath including a lumen, a distal end, and a proximal end. The device may further include an end-effector unit and an elongate member connected to the end-effector unit. The end-effector unit and the sheath may be movable relative to each other to achieve a first state of the end-effector unit and a second state of the end-effector unit. Moreover, the medical device may include a handle having a first handle portion connected to the proximal end of the sheath, a second handle portion connected to the proximal end of the elongate member, and a compliant member longitudinally aligned with the sheath between the first handle portion and the second handle portion. The first and second handle portions may be configured such that relative movement of the first and second handle portions causes the end-effector to move between the first and second states.

A method of preparing a distal femur for a knee joint implant includes mounting a patient-specific bone engagement surface of a femoral alignment guide on a complementary surface of a distal femur of a patient. A plurality of alignment pins is inserted through a corresponding plurality of guiding bores of the femoral alignment guide into the distal femur. A cutting guide is mounted on first and second alignment pins of the plurality of alignment pins, and a first resection of the distal femur is made using the cutting guide while cutting through the femoral alignment guide.

An articulating instrument including a distal assembly having first and second configurations and intermediate configurations between them. At least one of the first and second configurations is substantially stable such that the distal assembly of the instrument has a tendency to remain in the stable configuration when placed in that configuration by a user of the instrument. Preferably, the distal assembly terminates in a distal tip unit defining at least one distal feature that is useful for manipulating tissue.

A surgical tool handle for holding, securing and portioning orthopedic tools is described. The surgical tool handle having a tool attachment mechanism comprising a bias member connected to an actuator. The bias member is positioned within a distal end opening within the handle. Rotation of the actuator causes rotation of the bias member such that when a connection member of a tool, such as a broach, rasp or other cutting tool, is positioned within an opening of the bias member, the bias member wraps around and tightens onto the connection member. Rotating the actuation cable in an opposite direction rotates the bias member in the opposite direction, which thereby releases the tool connection member, and the tool, from the handle.

A surgical tunneler assembly is used to pass a cable or other elongate member through the skin. A surgical tunneler may include a lance including a first segment, a second end segment, and a connector on each one of the first end segment and the second end segment. A cable adapter includes a lance connection portion and a cable connection portion. The lance connection portion engages and disengages the connectors. The cable connection portion engages and disengages a cable. A handle engages and disengages the lance.

A sleeve clamp has a body with a through bore for receiving a sleeve, and a clamping element. The clamping element includes a clamping edge and may be arranged at the body so as to be movable between two positions, i.e. a neutral position and a deflected position. In the neural position, the clamping edge protrudes laterally into a lumen which is occupied by the sleeve when the sleeve is received in the through bore. In the deflected position, the clamping element may be elastically deformed and the clamping edge does not protrude into the lumen which is occupied by the sleeve when the sleeve is received in the through bore.

An extractor for removing an implanted lead from a patient. The extractor includes a lumen dimensioned to receive the lead therein, a cutter at the distal portion for cutting tissue adjacent the lead, a distal clamping structure and a proximal clamping structure The proximal clamping structure and lead are relatively movable to extract the lead.

In one representative embodiment, a gripping and pushing device for a medical instrument comprises an elongated main body defining a lumen. The elongated main body comprises one or more deflectable portions that can be pressed radially inwardly toward a shaft of the medical instrument extending through the lumen. One or more elastomeric gripping layers can be secured to the inner surface of a respective deflectable portion at axially spaced apart attachment locations. The one or more gripping layers are axially deformable relative to the one or more deflectable portions between the attachment locations when manual pressure is applied to the one or more deflectable portions to press the one or more gripping layers against the shaft and move the shaft longitudinally into a patient's body.
