DEVICE FOR SECURING HEART VALVE LEAFLETS

A fixation device for securing together leaflets of a heart valve is provided. The fixation device may comprise two plates that are disposed on either side of the tricuspid valve. The plates may be secured to one another by a locking clip, thereby securing the valve leaflets between the plates.

ORGAN SUCKING AND GRASPING TOOL

Disclosed is an organ sucking and grasping tool capable of reducing the height of the sucking and grasping tool, capable of reserving a viewing field for an endoscope, capable of reserving space for operations, and including a suction cup responsive to the deformation of an organ and unlikely to be detached. An organ sucking and grasping tool includes a suction tube body and a plurality of suction cups for organ suction provided at a front end portion of the suction tube body. The organ sucking and grasping tool sucks, elevates, and grasps an organ using suction force generated by the suction cups. The suction cups are held by a ring-shaped holder provided at the front end portion of the tube body, and an annular flange is provided at an open end portion of each of the suction cups.

Method and apparatus for passing suture through tissue

A suture passer comprising: a hollow tube, the hollow tube comprising a distal end, a proximal end, and a lumen extending from the distal end to the proximal end; and a clamping rod slidably received in the lumen of the hollow tube, the clamping rod comprising a distal end and a proximal end, the distal end being bifurcated into a first arm and a second arm, one of the first and second arms extending distally of the other of the first and second arms and including a clamping surface; wherein at least one of the first arm and the second arm comprises a friction-enhancing surface for facilitating manipulation of a suture via engagement of the suture with the friction-enhancing surface.

Arthroscopic devices and methods

An electrosurgical probe includes an elongated shaft assembly having a proximal end, a distal end, and a longitudinal axis. A distal housing is mounted on the distal end of the shaft and optionally includes a laterally open window where a plane of the window is generally perpendicular to the longitudinal axis of the shaft. An interior channel extends axially through the shaft and further through an interior of the housing to the window in the housing. An electrode member with a serrated or other elongated edge may extend longitudinally across the window and may be configured to reciprocate the elongated edge longitudinally relative to the window.

Ophthalmological apparatus for the breakdown of eye tissue

An ophthalmological apparatus includes a handle for manually holding and applying the ophthalmological apparatus, fastening abilities for fixing the ophthalmological apparatus at an eye, a light source, and a light projector for the focused projection of light pulses for punctiform tissue breakdown at a focal point in the interior of the eye tissue. The ophthalmological apparatus also includes a movement driver for moving the light projector. The movement of the light projector and therefore that of the focal point with the assistance of the movement driver permits a dimensioning of the optical projection system of the light projector which is substantially smaller than in the case of an ophthalmological apparatus where the focal point is moved exclusively by an optical projection system.

DEVICES AND METHODS FACILITATING SLEEVE GASTRECTOMY AND OTHER PROCEDURES

A device for use in bariatric surgery includes a flexible hollow tube extending from a proximal end to a distal end and defines a channel therebetween. A series of openings is defined in a distal portion of the tube allowing for fixation of tissue using suction. A flexible member has an initial position disposed alongside the tube and is deployable to a subsequent position in which the flexible member engages a greater curvature of a stomach. The flexible member is configured to be deployable to automatically assume a shape of a greater curvature of a stomach. The flexible member includes a bulging region and a tapering region when deployed. The flexible member is releasably attached to the distal end of the tube.

PARTIAL EVERSION ANASTOMOSIS JUNCTURE FORMATION AND SUTURING

Disclosed embodiments include apparatuses, systems, and methods for facilitating surgical anastomosis between bodily passages. In an illustrative embodiment, an eversion mechanism is configured to partially evert a distal portion of an opening of a receiving passage and further configured to leave a proximal portion of the opening of the receiving passage in a non-everted position. A donor support mechanism is configured to partially evert a distal portion of an opening at an end of a donor passage and further configured to leave a first proximal portion of the end of the donor passage in a non-everted position. The donor support mechanism is further configured to form a passage juncture at the end of the donor passage and the opening of the receiving passage. A suturing mechanism is configured to motivate a filament through a generally helical path around the passage juncture to suture the donor passage to the receiving passage.

Devices, systems, and methods for accessing the internal and external tissues of the heart are disclosed. At least some of the embodiments disclosed herein provide access to the external surface of the heart through the pericardial space for localized delivery of substances to the heart tissue. In addition, various disclosed embodiments provide access to the internal surface of the heart for aspiration and delivery of substances to a targeted region without disturbing or interfering with nearby structures or surfaces.

Suturing System

A suturing system including apparatus and methods for disposing stitches in a substrate comprising a thread carrier which inserts a thread in the substrate at a first location and withdraws the thread from the substrate at a second location.

Systems and methods of tissue closure
11369374 · 2022-06-28 · ·

Apparatus, systems, and methods are described for closing the base of a left atrial appendage or other tissue structure. A tissue closure device comprises a pair of legs having compliant surfaces for engaging against opposite sides of the tissue structure. A plurality of axially spaced-apart tissue-penetrating fasteners are delivered from one leg to the other to pierce the intervening tissue and hold the closure device in place on the tissue structure.
