SWAGING SYSTEMS FOR ATTACHING SURGICAL NEEDLES TO SUTURES HAVING ON-PRESS TESTING OF SUTURE ATTACHMENT STRENGTH
A swaging system for attaching surgical needles to sutures and testing the attachment strength includes a frame, a bottom swaging die mounted on the frame, and a top swaging die mounted on the frame and being moveable up and down along a swaging axis that is aligned with the bottom swaging die. The bottom swaging die includes a hinge mechanism with a bottom plate mounted to the frame and a top plate overlying the bottom plate. The top and bottom plates are pivotally connected for enabling the top plate to pivot relative to the bottom plate. The bottom swaging die includes a swaging tool that extends toward the top swaging die along the swaging axis, and a load cell disposed between the top and bottom plates for monitoring load. The system includes a control system having one or more pull test programs stored therein for evaluating pull tests on armed surgical needles to determine if the armed surgical needles are acceptable or unacceptable.
Reconfigurable suture needles being transformable between higher profile configurations and lower profile configurations
A reconfigurable suture needle includes an elongated body having a curved proximal section and a curved distal section. The curved proximal section is hollow and includes an elongated conduit extending from a proximal end to a distal end thereof. The curved distal section includes a needle point at a distal end thereof and a hollow post projecting proximally from a proximal end thereof. A suture thread passes through the elongated conduit of the curved proximal section and has a distal end that passes through the hollow post of the curved distal section for being secured to the proximal end of the curved distal section. The elongated body has a first configuration with a higher profile in which the hollow post of the curved distal section is inserted into the elongated conduit at the distal end of the curved proximal section, and a second configuration with a lower profile in which the hollow post of the curved distal section is uncoupled from the elongated conduit at the distal end of the curved proximal section.
CIRCULAR NEEDLE APPLIER WITH ARTICULATING AND ROTATING SHAFT
A surgical suturing device has an elongate shaft has a proximal end, a distal end, and a longitudinal axis between the proximal and distal ends. An actuator is connected to the proximal end of the elongate shaft. A circular needle applier is on the distal end of the elongate shaft. The circular needle applier has an arced needle and a needle driver operatively connected to the actuator to rotate the arced needle in a circular path. A joint is positioned between the proximal and distal ends of the elongate shaft. The joint is operatively connected to the actuator to selectively articulate the shaft. A bearing is on the shaft positioned distally of the joint. The bearing is operatively connected to the actuator to selectively rotate the circular needle applier about the longitudinal axis.
METHODS OF SURGICAL FASTENING
An apparatus and a method for surgical fastening is disclosed. An illustrative apparatus for tissue suturing includes a cartridge having a suturing needle having a pointed end and a blunt end, the suturing needle capable of rotating about an axis, a reciprocating needle drive, and an actuator capable of releasably engaging the needle drive to rotate the needle. A method for suturing tissue is provided that includes placing a suturing device having a cartridge containing a suturing needle to span at least one tissue segment, activating an actuator to cause rotational movement of the suturing needle through the at least one tissue segment, and deactivating the actuator to stop an advancing movement of the suturing needle to cause a suturing material to be pulled through the at least one tissue segment forming a stitch.
DEVICES AND METHODS FOR MINIMALLY INVASIVE SUTURING
Devices and methods for minimally invasive suturing are disclosed. One suturing device for minimally invasive suturing includes a proximal section a distal end, and an intermediate region therebetween. The device includes a suture head assembly having a suturing needle with a pointed end and a second end. The suturing needle is capable of rotating about an axis approximately perpendicular to a longitudinal axis of the device, wherein the pointed end of the suturing needle is positioned within the suture head assembly prior to deployment of guides that are adapted and configured to guide the needle around a circular path when advanced by a drive mechanism having a needle driver for engaging and rotating the suturing needle.
ARTHROSCOPIC SURGICAL DEVICE
An arthroscopic bone channel forming and suturing system useful following formation of a first and a second generally straight channel in a bone, the second channel not intersecting the first channel, the system including a curved bone puncture needle configured to be insertable into the first channel, a curved needle driving assembly configured to manipulate the curved needle to form a curved junction between the first channel and the second channel, a suture snare wire assembly configured to insert a suture snare wire to a suture snare wire pick-up location via the second channel in the bone and a coordinated multi-function driving assembly operative to operate the curved needle driving assembly and the suture snare wire assembly in coordinated operation to cause the suture snare wire to be pulled from the suture pick up location and through the first channel via the junction.
SUTURING DEVICES FOR HEART VALVE SURGERY
Disclosed are devices and methods for delivering several sutures accurately and simultaneously around the perimeter of an annular prosthetic device (prosthetic heart valve, annuloplasty ring, etc.) to secure the prosthetic device within a native heart valve region. Devices can comprise a proximal handle portion including an actuator and a distal suturing portion including several curved and straight needles arrayed around the shaft axis. The straight needles and the curved needles are configured to simultaneously guide a plurality of sutures through the native tissue and through the annular prosthetic device. The actuator can cause the straight needles to move axially relative to the curved needles and can also cause the curved needles to rotate, such that the motions are coordinated to simultaneously place all the sutures.

Perfect Closure Surgical Needle
This surgical needle may reduce unwanted and unanticipated tissue distortion and/or tearing and undesirable scar tissue during wound healing. The surgical needle will guide tissue separation more properly along planes of tissue stress, minimizing tissue distortion and improving tissue apposition.
ANCHOR ASSEMBLY
An anchor assembly includes: an elongate and flexible anchoring implant for inserting into a bore of bone or tissue, the implant having proximal and distal ends with sidewalls extending therebetween, a suture having: first and second segments between the proximal and distal ends of the implant and, passed through a first and second side wall portions of the implant, respectively; A bridging loop between the two segments, and at or adjacent an in-use upper portion of the implant that includes the proximal end; wherein each of the segments has respective terminal ends of the suture extending from the implant; Applying tension to the terminal ends, when implant is in bone or tissue, causes the proximal end to be drawn towards the distal end to effect change of the implant shape from elongate and radially narrow into axially shortened and radially extended configurations to deploy the implant in the bore.
