Devices and methods for suture placement
A suturing device includes a curved needle, a suture, an elongate body, an actuator and a curved needle holder. The suture connects with the curved needle. The actuator is operable between a first operating position and a second operating position. The curved needle holder extends away from a distal end portion or is provided as part of the distal end portion of the elongate body. The curved needle holder includes a distal end section having a distal-most tip. The curved needle holder defines a curved needle passage and a distal opening. Movement of the actuator from the first operating position toward the second operating position moves the curved needle with respect to the curved needle holder toward a released condition. The distal end section is configured to allow the curved needle to release from the curved needle holder at a location offset from the distal-most tip.
BI-DIRECTIONAL BARBED SUTURE WITH TAILORED SUTURE SEGMENTS
A wound closure device can be provided as described herein. In an example, the wound closure device includes a first suture segment having a first suture configuration and a second suture segment having a second suture configuration. The first and second suture configurations can be different from each other. For example, the first suture configuration can includes a first set of characteristics such as barbed or non-barbed, barb sizes, filament sizes, colors, materials, and/or the like and the second suture configuration can include a second set of characteristics such as barbed or non-barbed, barb sizes, filament sizes, colors, materials and/or the like that can be different from the first set of characteristics. The wound closure device can further include connecting section configured to provide a transition from the first suture segment to the second suture segment.
SUTURE METHODS AND DEVICES
A barbed suture including a body with barbs on the periphery, a pointed end, and an anchor at one end to resist movement of the suture in the direction of the pointed end is provided. One or more limbs on the anchor may be provided, which may be arcuate, of varying lengths, and of varying distribution about the periphery of the suture body. Other anchor designs are provided. Methods of placing single-directional and bi-directional barbed sutures to approximate the tissue on each side of a wound and to position and support tissue in the absence of a wound, as in cosmetic surgery, are provided, and may include terminal J-stitches or S-stitches. Methods of placement may be made with sharp, pointed ends, which may be needles, or Insertion devices. Sinusoidal patterns of sutures that have amplitudes generally perpendicular to the resultant holding force of the suture are provided.
Devices and methods for suture placement
A suturing device includes an elongate body, an actuator, a needle holder and a knot pusher. The elongate body includes a proximal end portion and a distal end portion. The actuator interacts with the elongate body and is operable between a first operating position and a second operating position. The needle holder extends away from the distal end portion or is provided as part of the distal end portion of the elongate body, and includes a distal end section having a distal-most tip. The needle holder defines a needle passage and a distal opening adjacent the distal-most tip. The knot pusher connects with and extends away from at least one of the elongate body and the needle holder.
Suturing kit and package
A suturing kit includes a suture and a suture holder for holding the suture. The suture has a first end and a second, opposite, end. The suture holder includes an elongated wall defining a suture receiving passage that is elongated along a longitudinal axis and terminates at a suture exit opening. The suture receiving passage has a width at least twice the diameter of the suture and receives the suture such that the suture is folded over forming a half loop section spaced from the suture exit opening. A first second of the suture extends from the half loop section toward the first end and a second section of the suture extends from the half loop section towards the second end. The first section and the second section of the suture within the suture receiving passage are aligned parallel to the longitudinal axis.
Fixation devices, systems and methods for engaging tissue
System for fixation of leaflets of a heart valve including a delivery catheter having an elongated shaft, a proximal end portion and a distal end portion configured to be positioned proximate native leaflets of a heart valve from a remote vascular access point, the delivery catheter further includes a rotatable actuator rod having a threaded fastener at a distal end thereof, and a fixation device releasably coupled by a threaded connection to the threaded fastener of the actuator rod. The fixation device includes a first arm moveable between a closed position and an open position, a second arm moveable between a closed position and an open position. The fixation device further includes a first gripping element movable relative to the first arm in the open position, the first gripping element biased toward the first arm to capture a first leaflet of the heart valve therebetween, and a second gripping element movable relative to the second arm in the open position, the second gripping element biased toward the second arm to capture a second leaflet of the heart valve therebetween. The first gripping element and the second gripping element each includes a plurality of barbs extending therefrom, the plurality of barbs of each of the first gripping element and the second gripping element being aligned transversely in at least one row. The fixation device further includes a covering disposed on each of the first gripping element and the second gripping element, wherein the plurality of barbs of the first gripping element and the second gripping element, respectively, protrude through the covering.
Method of repairing aortic valve
A method of repairing an aortic valve includes, in a following order: an aortic wall incision step; an aortic valve forming step; and an aortic wall suturing step. In the aortic wall incision step, an aortic wall is cut so as to expose an aortic valve side in the inside of an aortic duct to an open atmosphere. In the aortic valve forming step, the aortic valve is formed by restricting a distance between commissures disposed adjacently to each other by placing a thread between the plurality of commissures disposed adjacently to each other. In the aortic wall suturing step, the aortic wall cut in the aortic wall incision step is sutured so as to close the aortic wall.
SURGICAL DEVICE
This disclosure relates to a surgical device with a single trigger configured to rotate and slide. The disclosure also relates to a method of repairing damaged tissue.
ANASTOMOSIS ASSEMBLY
Provided is a device for use in anastomosis particularly (although not exclusively) suitable for anastomosis of tubular organs within the body, particularly small tubular organs (such as blood vessels, bile duct, lymph duct, nerve ducts, epididymis, etc.).
Method and apparatus for double loop stitching
A sewing needle having a needle tip configured to pass through a sewing material and a first needle portion that follows the needle tip. A second needle portion is removably connected to the first needle portion and includes an end that is inserted into an elongate hollow receiver located on the first needle portion. The second needle portion follows the needle tip through said sewing material substantially simultaneously with the first needle portion. A first thread connection formed on the first needle portion is configured to carry a first portion of said thread through the sewing material and a second thread connection formed on the second needle portion is configured to carry a second portion of said thread through the sewing material. After passing through the sewing material, the first and second needle portions are separated, brought around outside edges of the sewing material and reconnected for subsequent stitching.
