Medical devices that include a trigger assembly for a rotatable catheter and methods of use are described. An example medical device includes a housing, a catheter, a drive assembly, and a trigger assembly. The trigger assembly is partially disposed within the housing and includes a trigger, a drive initiator, a drive member, a flip drive, and a biasing member. The trigger is moveable between a first position and a second position relative to the housing. The flip drive is moveable between a neutral position, a first drive position, and a second drive position. The drive assembly moves relative to the housing when the flip drive is in the first drive position and the trigger is moved from its first position to its second position.

A retractor tool apparatus and method of manipulation are described. The retractor tool may include one or more blades. The one or more blades may be cranial/caudal blades. The one or more blades may be a medial blade. One or more portions of the retractor tool may be adjustable.

A medical device includes a link, a first tool member, a second tool member and a third tool member, which each have a proximal end portion movably coupled to the link and a distal end portion. The distal end portion of the first tool member can engage a first object and be associated with a first medical function, the distal end portion of the second tool member can engage a second object and be associated with a second medical function, and the distal end portion of the third tool member can engage the first object or the second object and be associated with the first and/or second medical function. Each of the first, second and third tool members can move relative to the link independent of movement of the each of the other tool members.

An exemplary embodiment relates to an input unit (10) for operating a medical instrument (12) with a hollow shaft (14) extending along a longitudinal axis (L) for receiving guide wires (20), with a tool (16) arranged on the distal side of the shaft (14), extending along an extension axis (E) and a control unit (18) arranged proximally on the shaft (14) for handling the tool (16) by means of the guide wires (20), comprising first input means (22) for continuous, pivoting and rotation-true, preferably uninterrupted and/or absolute, conversion of an ergonomically limited user input, in particular a natural user movement of movable first operating means, into an adjustment movement of the tool (16) in a first handling mode, in order to pivot the tool (16) by means of the control unit (18) relative to the longitudinal axis (L) in a limited way and/or to rotate about the extension axis (E) in a limited way.

A surgical instrument includes a housing having a first handle and an elongated shaft extending therefrom. An end effector is disposed at a distal end of the elongated shaft and includes first and second jaw members, the first jaw member including a staple cartridge configured to house a series of staples therein. A second handle is operably coupled to the housing and is selectively moveable relative to the first handle to actuate the first and second jaw members between an open position and a closed position for grasping tissue. A first switch is activatable to supply energy to one of the jaw members. A stapler mode switch is actuatable between an unactuated position wherein movement of the second handle moves the jaws to the second position and an actuated position wherein movement of the second handle moves the jaws to the second position and drives the staples through tissue.

According to one example, an adjustable cut guide for resecting a bone can include a base, a cam, an actuator, and an insert. The base can include a channel extending between a first end and a second end and a slot intersecting the channel. The cam can extend into the slot, and the cam can be coupled to the base within the slot to rotate between a first position and a second position. The actuator can be disposed in the slot, where the actuator can be translatable by rotation of the cam between an extended position when the cam is in the first position and a retracted position when the cam is in the second position. The insert can be disposed within the channel of the base and the insert can be secured relative to the base by the actuator when the actuator is in the extended position.

Systems and methods for aspiration system retrievers that are configured to remove undesirable intravascular material. The retrievers can be utilized in connection with manually operated or automatic recirculation aspiration systems. The retrievers can be configured to transition between various configurations, including a collapsed configuration suitable for being advanced through a lumen of a catheter and an expanded configuration suitable for collecting or mechanically disrupting the undesirable intravascular material.

Embodiments of the invention include a tissue repair system and related components and associated methods that provide for suturing of tissue using three or more suture anchoring implants, including multiple pairs of connected implants in some embodiments, all of which may be deployed from a single device. Some embodiments achieve this by employing a push mechanism capable of being activated to advance the push mechanism incrementally to discrete positions within the device and deploy implants one at a time from the device.

A method of evaluating soft tissue of a human joint which includes two or more bones and ligaments, wherein the ligaments are under anatomical tension to connect the bones together, creating a load-bearing articulating joint, the method includes: inserting into the joint a tensioner-balancer that includes a means of controlling a distraction force; providing an electronic receiving device; moving the joint through at least a portion of its range of motion; while moving the joint, controlling the distraction force, and collecting displacement and distraction load data of the bones; processing the collected data to produce a digital geometric model of the joint, wherein the model includes: ligament displacement data along a range of flexion angles and ligament load data along a range of flexion angles; and storing the digital geometric model for further use.
