Benefits of technology

Enables rapid, reliable, and efficient tissue ligation and fixation, reducing the time spent on suturing and minimizing the risk of errors, while allowing for adjustable suture length and depth, suitable for both open and minimally invasive surgeries.

Problems solved by technology

Placing a number of stitches can be tiring and time-consuming which can lead to suturing errors that can compromise the integrity of repair.
In addition, manipulation of a suture needle as well as access to the suturing location can be difficult especially in minimally invasive surgery due to the nature of the minimally invasive surgery and / or the limited anatomical space around the target tissues, while tying knots with a desired amount of tension requires precise manipulation of the suture ends further complicating and slowing open, and in particular, minimally-invasive surgeries.
Although tissue stapling devices and adhesives as well as devices which employ a combination of anchors and sutures can traverse these limitations of suturing by enabling rapid ligation of tissue, the tissue ligation / fixation created thereby is oftentimes less reliable or does not involve easy access and large number of sutures.

Prototype Bench Testing 1

[0141]Initial experiments were performed with a prototype that includes the anchoring elements 24, threads 26and insertion device 12 in order to determine feasibility of delivering an anchored suture through excised tissue. A 0.8 mm O.D. hollow alloy 8 mm in length was curved at the tips to form a groove for locking the suture. The tube was also tapered at the ends to facilitate penetration through a tissue access site. Ten individual anchoring elements were threaded over a 2-0 silk thread and the thread with threaded anchors was inserted into a 10 cm long hollow needle with a sharp tapered distal end capable of tissue piercing. A rod was fitted into the needle through the proximal end to serve as a plunger for expulsion of a suture anchor.

[0142]A standard 4×4 cm poly-propylene mesh was used along with a 20×20 cm piece of bovine abdominal muscle as the tissue model. The mesh was placed over the tissue and the needle was inserted through the mesh and into the...

Prototype Bench Testing 2

[0143]A second prototype including handle was fabricated by 3D printing the handle and actuating mechanism and attaching it to concentrically arranged tubes (FIG. 8A). The prototype was tested by sequentially delivering several anchoring elements through a 3 cm thick foam board forming a running stitch (FIG. 8B-8C). The prototype was then used to deliver two anchoring elements (each with attached suture loop) through fascia of excised bovine muscle tissue to simulate fascia anchoring (FIG. 9A). The load capacity of a single anchor point exceeded 600 grams (FIG. 9B).

[0144]Reference is now made to FIGS. 10A-10H which are illustrations of apparatus 10 in several positions illustrating 8 steps in the insertion and / or delivery of a single anchoring element 24 using insertion device 12. FIGS. 10A-10H shows the advancing and positioning of the various elements of apparatus 10 (with respect to each other), discussed and disclosed above during the insertion of insert...

Abstract

An apparatus for suturing a tissue. The apparatus includes an outer tube, a thread threaded in the outer tube and at least one anchoring element located inside the outer tube and configured to be inserted into the tissue from an outlet end of the outer tube. The outer tube is configured to freely accommodate the thread and the at least one anchoring element, and the anchoring element includes a body adapted to be threaded on the thread and having at least locking element for locking the thread to the anchoring element.
