The present invention relates to a laparoscopic surgery instrument that does not require a trocar, the laparoscopic surgery instrument including: a first part inserted into the body of the abdominal cavity and provided with a surgical instrument; and a second part placed outside the body of the abdominal cavity and coupled to the first part to manipulate the operation state of the surgical instrument, wherein the first part and the second part are primarily coupled to each other by magnetic force while the first part is inserted into the body.

An end effector assembly of a surgical instrument includes a clevis defining a longitudinal axis and including first and second arms spaced-apart relative to one another and first and second jaw members supported by the clevis. At least one of the jaw members is movable relative to the other and the clevis between a spaced-apart position and an approximated position for grasping tissue between the jaw members. The clevis includes first and second locating features on outwardly-facings sides of the first and second spaced-apart arms, respectively. The first and second locating features are configured to facilitate engagement and alignment of the end effector assembly within a test fixture.

A device and method is provided for a trackable suction tool for surgical use. The suction tool provides multiple configurations for the tip and reference tree, while allowing tracking by a navigation system. The tip and reference tree are attached to the suction tool handle by a snap fit, a threaded ring with key and slot connections or semi-Allen key connections, providing specific rotational configurations of the tip, handle and reference tree with each other. The handle may include a rotatable outer sleeve with a tear-shaped orifice for suction regulation and an inner sleeve with a corresponding opening, allowing variable placement of the tear-shaped orifice relative to the longitudinal axis of the suction tool. The features of the device allow a suction tool with multiple configurations to be trackable with a navigation system.

An example anchor-manipulation tool includes (i) at a distal portion of the tool, an anchor-engaging element and an actuator, (ii) at an extracorporeal proximal portion of the tool, a controller, and (iii) a flexible longitudinal member extending between the proximal portion and the distal portion. The distal portion of the tool can be transluminally advanced to an anchor that is intracorporeally implanted in a subject. Subsequently, the anchor-engaging element can be engaged with an eyelet defined by a head of the anchor. Subsequently, the controller can be used to transition the tool into an articulatably-coupled state in which: (i) the eyelet at least in part inhibits movement of the anchor-engaging element away from the anchor, and (ii) the distal portion of the anchor-manipulation tool is deflectable with respect to the anchor. Subsequently, the anchor can be de-anchored by using the anchor-manipulation tool to apply a de-anchoring force to the eyelet.

A device for delivering an agent that includes a housing configured to store an agent and a cone assembly at least partially received within the housing. The cone assembly including an inner wall configured to be adjacent to the agent, an outlet channel extending from the inner wall, an inlet channel, and an intermediate channel between the outlet channel and the inlet channel. The inlet channel is in fluid communication with the outlet channel via the intermediate channel. The device includes a filter disposed within the inlet channel and positioned adjacent to the intermediate channel. The filter including a plurality of pores configured to permit a fluid received by the inlet channel to pass through the intermediate channel to mix with the agent adjacent to the inner wall.

A device and method is provided for a trackable suction tool for surgical use. The suction tool provides multiple configurations for the tip and reference tree, while allowing tracking by a navigation system. The tip and reference tree are attached to the suction tool handle by a snap fit, a threaded ring with key and slot connections or semi-Allen key connections, providing specific rotational configurations of the tip, handle and reference tree with each other. The handle may include a rotatable outer sleeve with a tear-shaped orifice for suction regulation and an inner sleeve with a corresponding opening, allowing variable placement of the tear-shaped orifice relative to the longitudinal axis of the suction tool. The features of the device allow a suction tool with multiple configurations to be trackable with a navigation system.

In a first aspect of the subject invention, an iris expander is provided which includes a non-metallic, unitary, multi-segmented body which is expandable from a first state to a second state. The second state defines a larger footprint than the first state with the body being defined by a plurality of segments connected by living hinges. In a further aspect, an iris expander is provided which includes a multi-segmented body that is expandable from a first state to a larger-footprint second state. At least one aperture is formed in the body with a channel extending therefrom embedded in the body such that no portion thereof is exposed externally of the body. The channel is formed to accommodate a portion of an instrument for causing adjustment of the body with avoidance of direct contact of the instrument with the tissue of the iris.

System for use with tissue of a heart comprises a tissue anchor comprising an engaging head that has a coupling eyelet that defines an eyelet plane, and a helical tissue-coupling element, reversibly anchorable to the tissue, and having a central helix axis that lies on the eyelet plane. The system also comprises an anchor driver, having a distal portion that has a casing that defines a slot, the slot defining a slot plane, and dimensioned to receive at least part of the eyelet therein in a manner in which the eyelet plane is coplanar with the slot plane. The anchor driver also comprises a detent, configured to reversibly inhibit movement of the eyelet with respect to the slot. The anchor driver is configured to anchor the tissue anchor to the tissue by rotating the tissue anchor by applying a rotational force to the eyelet. Other embodiments are also provided.

A surgical instrument is disclosed. The instrument includes a handle portion, a body portion extending distally from the handle portion and defining a first longitudinal axis and an articulating tool assembly defining a second longitudinal axis and having a proximal end. The articulating tool assembly is disposed at a distal end of the body portion and is movable from a first position in which the second longitudinal axis is substantially aligned with the first longitudinal axis to at least a second position in which the second longitudinal axis is disposed at an angle with respect to the first longitudinal axis. The instrument also includes an articulation mechanism configured to articulate the articulating tool assembly, the articulation mechanism including an articulation sensor assembly configured to transmit a sensor signal to a microcontroller which is configured to determine an articulation angle of the articulation assembly.
