SYSTEMS, DEVICES AND METHODS OF MAKING HIGHLY ELASTIC SUTURE NEEDLES FOR MINIMALLY INVASIVE SURGERY

An elastic suture needle for passing through a smaller cannula used in minimally invasive surgery includes an elongated body having a proximal end, a distal end, a length extending from the proximal end to the distal end, a top surface extending along the length of the elongated body, and a bottom surface extending along the length of the elongated body. The elongated body has dimensions that are calculated using the equation T/L.sub.N < (2*.sub.σ)/(πE), where T is the thickness of the elongated body, L.sub.N is the length of the neutral axis of the elongated body, σ is the yield strength of the elongated body, and E is the Young’s modulus of the elongated body. The elongated body is made of stainless steels such as martensitic stainless steels, austenitic stainless steels, martensitic-aged (mar-aged) stainless steels, and stainless steels sold under the registered trademark ETHALLOY® Needle Alloy.

Surgical suturing instruments

Side bite surgical suturing instruments or portions thereof for endoscopic, laparoscopic, endoluminal, and/or transluminal suturing facilitate the use of larger needles to get a bigger bite while suturing.

MENISCAL REPAIR DELIVERY DEVICE

Tissue repair devices include an advancement assembly comprising a rod portion configured to advance through a needle to expel first and second implants from the needle, a ratchet coupled to a proximal section of the rod portion and configured to advance the rod through the needle by axial and rotational movement, and an advancement member having a linear travel axis including a first bore connected to a second bore. A diameter of the first bore is smaller than a diameter of the second bore such that the first bore and the second bore comprise a stop. The rod portion has mechanical properties optimized to both conform to a needle curvature and provide sufficient compressive strength to expel implants from the devices.

METHOD AND APPARATUS FOR PASSING SUTURE

A device can pierce and hold tissue and then pass suture through tissue. The device can have a shuttle that can removably attach to a suture and jaws that can be rotatably opened and closed with respect to each other. A method for using the device to repeatedly pass the suture through the tissue without removing the suture or device from the target site is also disclosed.

TISSUE REPAIR SYSTEM

A tissue repair system for securing a first tissue to a second tissue is disclosed including an instrument with a handle, a shaft extending distally from the handle and a housing having a locked cover. A tissue anchor is disposed at a distal end of the shaft, and operatively coupled to an actuation member of the handle via a deployment member. The actuation member is configured to actuate the deployment member, deploy the tissue anchor and thereby couple the tissue anchor with the first tissue. The system also includes a repair member, for coupling the tissue anchor to the second tissue. Repair member has a first end operatively coupled to the tissue anchor and a second end attached to at least one coupling means. The repair member second end and coupling means are housed within the instrument housing. Actuation of the actuation member is configured to unlock the housing cover.

DEVICE AND METHOD OF PERFORMING CERCLAGE SACROCERVICOPEXY
20170360543 · 2017-12-21 ·

A medical device and method of use comprising a base portion having a length extending from proximal end and a distal end and a width extending from a first side to a laterally opposed second side. At least one arm extending from at least one of the first or second sides, the at least one arm extending a distance greater than the width of the base portion. The arm being configured to extend around at least a portion of a cervical isthmus.

SURGICAL CLOSURE APPARATUS AND METHOD
20170360435 · 2017-12-21 ·

A surgical closure apparatus includes an outer member dimensioned for positioning within a wound opening, a needle assembly at least partially positioned within the outer member and a suture configured for at least partially closing the wound opening within the tissue. The needle assembly includes an elongate member defining a longitudinal opening, a suture needle coupled to the elongate member and extending to a needlepoint and being configured for movement between an unarmed condition where the needlepoint is in a relative radial inward position and an armed condition where the needlepoint is in a relative radial outward position and a deployment member extending at least partially through the longitudinal opening of the elongate member and coupled to the suture needle. The deployment member is movable within the longitudinal opening to permit the suture needle to move between the unarmed condition and the armed condition.

LOADER FOR SURGICAL SUTURING
20170360432 · 2017-12-21 ·

A loader for a surgical suturing instrument is disclosed. The loader has a head having a protrusion configured to be releasably held by a tissue bite area of a surgical suturing instrument. The loader also has a tube interface. The loader further has one or more ferrule holders. The loader also has one or more ferrules, each corresponding to and held by one of the one or more ferrule holders and coupled to a suture end that leads from a tube releasably held by the tube interface.

Skin suturing device using rotating needles

A medical device for installing sutures to close an incision in tissue or human skin is disclosed. The suturing device may provide first and second arcuate needles. Once properly positioned, the first and second arcuate needles are driven through the sub-dermal layer, or alternatively through a superficial surface, of two sections of skin to be joined. This is done in arcuate fashion and at identical and symmetrical rates of angular displacement. During the driving or retraction process of the first and second arcuate needles, a suture is positioned within both the first and second sections of skin and transformed from a planar or a multi-planar serpentine orientation to a helical orientation. The resulting suturing process is thus much faster than conventional or manual suturing and results in superior wound approximation/alignment that will lead to decreased scarring compared to prior art devices.

AUTOMATED ROTATION OF A NEEDLE IN A COMPUTER-ASSISTED SYSTEM
20230190262 · 2023-06-22 ·

Techniques for automated rotation of a needle in a computer-assisted system include an end effector having a drive mechanism configured to be coupled to a curved needle and configured to rotationally actuate the curved needle along an arcuate path and a control unit coupled to the drive mechanism. The control unit is configured to, in response to receiving a first input, cause the drive mechanism to rotationally actuate the curved needle by a first preset rotation amount along the arcuate path, and, in response to receiving a second input, cause the drive mechanism to rotationally actuate the curved needle by a second preset rotation amount along the arcuate path.
