COLLAGEN CONSTRUCTS AND METHODS OF MAKING THE SAME
The present disclosure describes a medical construct. The medical construct includes a first layer comprising an array of collagen fibers, the first layer forming a core of the medical construct, and a second layer comprising a plurality of braided collagen fibers, wherein the second layer surrounds the core of the medical construct. In some embodiments, the medical construct may further include a third layer comprising a plurality of braided collagen fibers, wherein the third layer surrounds the second layer. Methods of manufacturing a medical construct also provided.
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.
Surgical instruments
In one form, a surgical needle has a curved needle body having a first end and a second end and defines an interior region between the first and second ends. The interior region contains a center of curvature of the needle body. The first and second ends each terminate in a point. The needle body has an intermediate portion between the first and second ends, and defines an internal surface facing the interior region and an external surface facing away from the interior region. A recess is thrilled within the external surface of the needle body. In another form, the needle is provided in a sterilized package together with one or more elongate filaments each having a proximal end coupled to the needle body within the recess. A container holds the surgical needle and the filament.
WOUND CLOSURE DEVICE
A wound closure device for closing a surgical wound in a tissue, wherein the wound closure device includes a first jaw, a second jaw and a handle. The first jaw is arranged for receiving a first cartridge including a plurality of slots for holding wound closers and wherein the second jaw is provided with a plurality of tracks. The plurality of tracks guide a respective one of the male ends and a respective one of the female ends towards each other and to an interlocked state where the respective one of the male ends and the respective one of the female ends are interlocked with each other.
SUTURE NEEDLE FOR UTERINE HEMOSTATIC COMPRESSION
A suture needle for uterine hemostatic compression comprises at least one suture needle and a suture thread. The at least one suture needle includes a body portion extending linearly in a lengthwise direction and a puncture portion provided at a tip of the body portion in the lengthwise direction to be thrust into a uterus. The suture thread is attached to a base end portion that is on an opposite side of the puncture portion in the suture needle. The puncture portion is formed as a spherical surface that bulges toward a tip side of the lengthwise direction. The spherical surface has a radius in a connection portion with the body portion substantially identical to a radius of the body portion.
Method for intra-abdominally moving an organ
A surgical tissue connector system for moving a first internal body tissue to a position away from a second internal body tissue and then holding the first internal body tissue in the position. Tissue connectors are secured to cords such that the length of cord between the tissue connectors can be easily adjusted in a laparoscopic work space.
METHODS AND DEVICES FOR CAPTURING AND FIXING LEAFLETS IN VALVE REPAIR
The present invention provides methods and devices for grasping, and optional repositioning and fixation of the valve leaflets to treat cardiac valve regurgitation, particularly mitral valve regurgitation. Such grasping will typically be atraumatic providing a number of benefits. For example, atraumatic grasping may allow repositioning of the devices relative to the leaflets and repositioning of the leaflets themselves without damage to the leaflets. However, in some cases it may be necessary or desired to include grasping which pierces or otherwise permanently affects the leaflets. In some of these cases, the grasping step includes fixation.
Method and apparatus for forming a self-locking adjustable loop
An apparatus can include a first flexible member having first and second ends and a first body extending therebetween that defines a first passage portion. A second flexible member can include first and second ends and a second body extending therebetween that defines a second passage portion. The first end of the first flexible member can pass into and through the second passage portion in a first direction such that the first end extends outside of the second passage portion. The first end of the second flexible member can pass into and through the first passage portion in a second direction such that the first end of the second flexible member extends outside of the first passage portion to form a self-locking adjustable flexible member construct. Applying tension to the first ends can draw the passage portions and corresponding second ends toward each other.
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.
SUTURING DEVICES AND METHODS FOR SUTURING AN ANATOMIC VALVE
A device for suturing an anatomic valve can comprise an elongate body, a suture catch mechanism and a suture clasp arm. The suture catch mechanism can be operatively coupled to the elongate body for movement between a retracted position and an advanced position. The suture clasp arm can be attached to the elongate body for movement between a retracted position and an extended position. The suture clasp arm can comprise a suture clasp configured to releasably retain a suture portion. In some embodiments, the suture clasp is positioned on the suture clasp arm such that the suture catch mechanism retrieves the suture portion from the suture clasp arm while the arm is at least partially retracted. In some embodiments, the suture clasp arm can be closed about a tissue portion without damaging the tissue portion.
