An instrument driver comprises a base and a jaw assembly coupled to the base. The jaw assembly includes a first jaw having a gripping surface and a second jaw having a gripping surface. The instrument driver further comprises a driver assembly operably coupled to the jaw assembly to advance an elongated member relative to the base by translating the first and second jaws toward each other, thereby closing the jaw assembly and gripping the member between the respective gripping surfaces of the first and second jaws, translating the jaw assembly in a first axial direction when the jaw assembly is closed, translating the first and second jaws away from each other, thereby opening the jaw assembly and releasing the member from between the respective gripping surfaces of the first and second jaws, and translating the jaw assembly in a second axial direction when the jaw assembly is opened.

CERVICAL TENACULUM DEVICE

A surgical device comprising a shaft comprised of a first end and a second end; a clamp configured to be locked or unlocked attached to the first end of the shaft; an actuator shaft that is removably coupled to the shaft and configured to open and close the clamp; and optionally an anchor.

Apparatus and method for heart valve repair

A device for gathering tissue of a heart valve leaflet may include an outer tube extending in an elongated direction, a capture tool moveable in the outer tube between a contained position and a use position, and a tissue securing component disposed at a distal end of the outer tube and adapted to be applied to tissue captured by the capture tool and to hold the captured tissue in a gathered configuration. The capture tool may include two grasping members that are moveable relative to one another in the elongated direction. Each grasping member may have a proximal portion and a plurality of fingers or barbs. The grasping members may be operable to capture tissue of the heart valve leaflet therebetween and to draw the captured tissue into the outer tube in the gathered configuration.

SURGICAL CLAMP

A surgical clamp including a pair of jaws, which may be used to ablate or create lesions in tissue. in an exemplary embodiment, the jaws are movable between an articulated position in which the jaws are separated and not parallel to one another, an opened position in which the jaws are separated and substantially parallel to one another, and a closed position in which the jaws are adjacent and substantially parallel to one another.

TREATMENT TOOL

Provided is a treatment tool including an elongated inserting section that is curvable or bendable, a wire that is disposed from an end effector to a proximal end side of the inserting section through the inserting section, the end effector being connected to a tip of the inserting section, and a power input section that is disposed on the proximal end side of the inserting section and configured to input power to a proximal end portion of the wire, and the wire transmits, to the end effector, power to drive the end effector, and the power input section is configured to increase the power to be input into the proximal end portion of the wire in response to displacement of the proximal end portion of the wire in a longitudinal direction, the displacement accompanying a curve or bend of the inserting section.

Expandable needle suture apparatus and associated handle assembly
10555731 · 2020-02-11 · ·

A surgical suturing device having an axis extending between a proximal end and a distal end is operable to move a suture through body tissue. An actuating rod extends between the handle assembly and the shaft. A needle assembly at the distal end of the actuating rod is movable with the actuating rod between an extended state and a retracted state. Bifurcated portions of the needle assembly define a suture slot, the bifurcated portions have a proximate relationship when the needle assembly is in the retracted state and having a separated relationship when the needle assembly is in the extended state. The needle assembly is biased to the retracted state and the bifurcated portions are biased to the separated relationship. A handle assembly is configured to releasably receive the needle assembly and is operable to move the needle assembly between a free suture state and a captured suture state.

10524817 · 2020-01-07 · ·

A device for removing an implanted object from a body vessel includes an actuator having an elongated sheath extending therefrom, the elongated sheath including a proximal portion and a distal portion. A tubular outer member has a proximal end attached to the distal portion of the elongated sheath, with a ramped surface at a distal end of the tubular outer member which constricts a diameter of a bore formed in the tubular outer member. A tubular inner member is located within the tubular outer member, the tubular inner member including a proximal end operably connected to the actuator and a distal end opposite the proximal end, the distal end of the tubular inner member including a plurality of resiliently flexible blades positioned to interact with the ramped surface of the tubular outer member such that the ramped surface is operable to deflect the resiliently flexible blades radially inwardly as the tubular inner member is advanced distally within the tubular outer member.

Tip for lead extraction device
10525261 · 2020-01-07 · ·

A tip engageable with an elongated sheath member for extracting a cardiac lead from an obstruction in a body vessel of a patient. The tip includes a tip body having a proximal end, a distal end, and a passageway extending therethrough. The tip body proximal end is engageable with the distal end of the sheath member distal end. The passageway of the tip is aligned with the passageway of the sheath such that the cardiac lead is receivable therein. The tip body distal portion has a plurality of sides extending circumferentially therearound, wherein the sides have respective ends and an inwardly directed radiused portion between the ends.

Surgical instrument for removing an implanted object
