A surgical instrument includes a handle assembly and a shaft portion extending distally from the handle assembly and configured to rotate relative to the handle assembly. The handle assembly includes an actuator and a gear that operably couples the actuator to the shaft portion. The gear is configured to transform a rotational motion of the actuator into a rotation of the shaft portion at a greater angular velocity than an angular velocity of the actuator.

Devices for assisting with the functioning of a tricuspid valve of a heart include a shaft, a flow optimizer, and an anchoring mechanism. A tilting mechanism can be configured to tilt the shaft relative to a central axis of the anchoring mechanism. Leaflets (e.g., multi-layer leaflets) of the flow optimizer can include a membrane and a rim, and the rim can have a higher stiffness than the membrane. A delivery system can be configured to deliver the device and adjust the position of the flow optimizer with respect to the anchoring mechanism.

Suture passer devices and methods of using the devices having one or more protective interlocks preventing or limiting operation of the suture passer when deployment of the needle may damage the apparatus or harm the patient. For example, described herein are suture passer devices that include an interlock preventing deployment of the tissue penetrator (needle) when the jaws are not clamped onto a tissue. Also described herein are interlocks preventing retraction of a jaw axially until the needle is retracted.

An inserter for attaching a modular yoke to a bone screw and for providing an indication of attachment, comprises a tubular body having a central lumen, distal and proximal ends, and an attachment portion for releasable attachment to a yoke having a bottom opening for receipt of a head of said bone screw. The inserter includes an inner shaft having a distal end configured to be received into the yoke, the shaft being axially movable within the lumen from first to second axial positions in response to the introduction of the bone screw head into the yoke bottom opening. An indicator button supported by the body is movable in response to axial movement of the shaft from a first indicator position indicating the first axial position of the shaft relative to the body to a second indicator position indicating the second axial position of the shaft relative to the body.

An orthopedic fixation system includes an implant and an implant insertion device. The implant transitions between a natural shape and an insertion shape. The implant includes a bridge defining a slot with a first end and a second end and first and second anchoring members extending from the bridge. The implant insertion device moves between a loaded position and an unloaded position. The implant insertion device in its loaded position inserts through the slot of the bridge and engages the bridge at the first and second ends of the slot such that the implant insertion device constrains the implant in its insertion shape. The implant insertion device in its unloaded position releases the implant.

A joint clamp for a surgical retractor system includes clamps, a cam bolt, and a cam lever. The cam bolt passes through the clamps. A cam lever comprising a cam head pivotally attached an upper portion the cam bolt to permit rotation about a pivot axis that is perpendicular to a longitudinal axis of the cam bolt. The cam head includes an outer surface that results in a distance between the pivot axis and an upper surface of the clamps being greater when the cam lever is rotated about the pivot axis to a clamping position than when the cam lever is rotated about the pivot axis to a non-clamping position. The clamping force may be calibrated or set via a cam bolt having an adjustable length and/or via a setting screw.

A system for treating a patient having thrombus including an aspiration catheter having an aspiration lumen configured to be coupled to a vacuum source and configured for aspirating thrombus therethrough, an elongate member having a straight distal portion configured to extend from the aspiration lumen into a thrombus within the blood vessel, and a manipulation device selectively coupled to the elongate member, the manipulation device being configured to apply motive force to the elongate member, wherein the motive force comprises a combination of motive force components comprising an alternating clockwise motion and counter-clockwise motion.

An articulated arm for support of an extended flexible medical instrument includes: a segment rotationally mobile around an axis of rotation, where the mobile segment can either be rotationally locked or unlocked, a handgrip including: a distal holding part to be hand held, a proximal support part connecting the distal holding part to the remainder of the structure, and an actuator on the distal holding part locking and unlocking mobility of the segment in rotation around the axis. The locking and unlocking actuator extends over the main part of the length of the distal holding part such that: pressure of the user's hand griping the distal holding part directly creates contact with the actuator, sufficient for automatically unlocking mobility of the segment in rotation and release of the distal holding part terminates contact with the locking and unlocking actuator, sufficient for automatically locking mobility of the segment in rotation.

A modular retractor may include a first body portion that houses a distraction mechanism for opening and closing a first arm and a second arm. A first pivoting member may be coupled to a distal end of the first arm and a second pivoting member may be coupled to a distal end of the second arm, for example. A first blade attachment mechanism may be coupled to the first pivoting member and a second blade attachment mechanism may be coupled to the second pivoting member. The first and second blade attachment mechanisms may be configured to couple to first and second blades and be independently inclinable. Various embodiments may include at least one connection point for connecting to at least one additional retractor module. Various embodiments may include at least one quick connect coupler for connecting to a snap on table mount.

A system for passing suture through biological tissue using a cannula, introducer or other minimally invasive means, to approximate, ligate, fixate, and/or close biological tissue. The system includes a hand actuator mechanism, an elongated tubular member housing a deformable tubular needle therein in operative communication with the hand actuator mechanism, and a jaw mechanism disposed on the tubular member distal end. The jaw mechanism having top and bottom members and a floating pivot mechanism, the top and bottom members in operative communication with the floating pivot mechanism. The floating pivot mechanism providing pivotal and axial articulation of the top member with respect to the bottom member.
