APPARATUS AND METHOD FOR MINIMALLY INVASIVE SUTURING
An apparatus and method for minimally invasive suturing is disclosed. A suturing device for minimally invasive suturing includes proximal section having a proximal end, a distal end, and a longitudinal axis therebetween, a suture head assembly extending from the distal end of the proximal section; a suturing needle having a pointed end and a blunt end, the suturing needle capable of rotating about an axis approximately perpendicular to a longitudinal axis of the proximal section, wherein the pointed end of the suturing needle is positioned within the suture head assembly prior to and after rotation of the suturing needle, and an actuator extending from the proximal end of the proximal section to actuate a reciprocating needle drive having a needle driver for engaging and rotating the suturing needle.
Dural repair device
A dural repair device operable with a single hand. The device comprises a handle and an outer arm having an end opening and a mechanism for holding a needle within the outer arm. The device also comprises an inner arm including a heel, a platform, an end opening, and a mechanism for catching a needle. The handle is activatable such that the inner and outer arms couple, the needle is caught by the mechanism for catching a needle within the inner arm, and when the inner and outer arms are uncoupled, the needle is transferred from the outer arm to the inner arm.
METHOD AND APPARATUS FOR CARDIAC PROCEDURES
Described herein are methods and apparatus for approximating targeted tissue using locking sutures. The locking sutures can be configured to receive suture ends that are interweaved through portions of the locking sutures. In a pre-deployment configuration, a locking suture can slide along suture tails and can be positioned at a target location within a target region. Once a desired position and/or tension is achieved, the locking suture can be transitioned to a post-deployment configuration where the locking suture constricts around the suture tails to inhibit relative movement between the suture tails and the locking suture.
Knot delivery device
A knot delivery device for securing a suture comprises an elongated body having a proximal end and a distal end, a pre-configured knot disposed at the distal end of the elongated body, a suture snare having a snare configured to capture suture material, wherein the snare extends through the pre-configured knot and a suture locker secured to one end of material forming the pre-configured knot, wherein tension applied to the suture locker tightens the pre-configured knot.
SYSTEM FOR MENISCAL REPAIR USING SUTURE IMPLANT CINCH CONSTRUCT
A system for repairing tears in soft tissue, e.g., meniscal tissue, by employing cinch stitching. More specifically, the present invention provides an apparatus for meniscal repair using a suture implant construct. The suture implant construct includes a first and second implant which are connected to each other via a length of suture. The implants are designed to be loaded on external surfaces of the first and second trocars.
System And Method For All-Inside Suture Fixation For Implant Attachment And Soft Tissue Repair
A system for repairing a meniscus includes a suture that includes a first anchor, a second anchor, and a flexible portion connecting the first anchor and the second anchor. The flexible portion includes a self-locking slide knot between the first anchor and the second anchor. The system also includes a needle having a longitudinal extending bore and an open end. The bore is configured to receive the first anchor and the second anchor. The system further includes a body portion operatively connected to the needle at a distal end of the body portion. The body portion has a lumen. The system also includes a pusher configured to rotate and slide within the lumen of the body portion and the longitudinal extending bore of the needle. The pusher has first and second stop surfaces, each of which is constructed and arranged to engage a proximal end of the body portion.
Specialized knot pusher for surgical port closure and suturing devices
A knot pusher device for surgical port closure includes a head portion having at least one suture guide inlet and at least one suture retainer, the head portion being configured to contact a suture knot inside an incision to close a portion of a surgical port made by the incision, and a coupling member operatively connected to the head portion, the coupling member enabling releasable connection of the knot pusher device to a suturing device.
SUTURE NEEDLE DEVICES AND SUTURE ATTACHMENT METHODS
According to one aspect, a medical device including a needle configured for use in suturing tissue is described. The needle may include a cylindrical body having a longitudinal axis extending between first and second ends of the cylindrical body. The needle may also include a lumen extending through the cylindrical body transverse to the longitudinal axis. The needle may further include a first end portion at the first end of the cylindrical body. The first end portion may include a sharp point configured to pierce tissue. An outer surface of the cylindrical body may define a first recess in communication with an opening of the lumen and configured to receive an end of a suture.
SUTURING CATHETER AND RELATIVE SYSTEM FOR PERCUTANEOUSLY REDUCING MITRAL INSUFFICIENCY
A suturing catheter for reducing mitral insufficiency by applying suturing points percutaneously is provided. The suturing catheter has a catheter body provided with a distal end and at least one internal lumen, at least one U-folded suture filament with two free ends, each provided with a suture needle, a pair of stylets, each provided with a catch needle, the suture and catch needles being provided with a connecting portion that allows a catch needle to mechanically engage with a suture needle, and a lever having a stapling arm, from which the suture needles protrude. The stapling arm, together with the catheter body, from which the catch needles protrude, defines a catch zone for a flap of a mitral valve. An opposite operating arm, together with the catheter body, defines an operating zone of the lever.
Suturing Device and Suturing Method
A suturing device includes a plurality of suture needles, a first-thread holding mechanism, a needle moving mechanism, and a thread turning structure. The thread turning structure is configured to locally turn a portion of a first thread hooked on a distal end portion of each of a plurality of suture needles in the first thread stretched in a first direction around a needle axis thereof such that the portion of the first thread extends in a direction along a third direction intersecting the first direction and a second direction, in a state where the plurality of suture needles have been moved in the second direction. Each of the plurality of suture needles has a side surface formed with a threading recessed groove extending through the side surface in the first direction in a state where each of the plurality of suture needles has been moved in the second direction.
