Benefits of technology

Enables reliable and efficient suturing in confined areas, reducing the need for large openings and minimizing tissue damage, thereby shortening recovery time and reducing the risk of infection.

Problems solved by technology

Suturing of tissue during surgical procedures is time consuming and can be particularly challenging in difficult to access body regions and regions that have limited clearance, such as regions partially surrounded or covered by bone.
However, in many cases, accessing the tissue in this manner is undesirable, increasing recovery time, and exposing the patient to greater risk of infection.
Although many such devices are available for endoscopic and / or percutaneous use, these devices suffer from a variety of problems, including limited ability to navigate and be operated within the tight confines of the body, risk of injury to adjacent structures, problems controlling the position and / or condition of the tissue before, during, and after passing the suture, and difficulties loading the suture into the device, particularly for threading multiple suture loops.
For example, some surgical instruments used in endoscopic procedures are limited by the manner in which they access the areas of the human body in need of repair.
In particular, the instruments may not be able to access tissue or organs located deep within the body or that are in some way obstructed.
In addition, many of the instruments are limited by the way they grasp tissue, apply a suture, or recapture the needle and suture.
Furthermore, many of the instruments are complicated and expensive to use due to the numerous parts and / or subassemblies required to make them function properly.
Suturing remains a delicate and time-consuming aspect of most surgeries, including those performed endoscopically.
Unfortunately, such devices cannot be adequately positioned for use in hard to navigate body regions such as the joints of the body, including the knee (e.g., meniscus) and the shoulder because there is not room within the confines of the body (e.g., joint region) to open the scissoring jaws.
The knee joint is one example of a tissue region that is notoriously difficult to access.
Typically, when the meniscus is damaged, a torn piece of meniscus may move in an abnormal fashion inside the joint, which may lead to pain and loss of function of the joint.
Early arthritis can also occur due to these tears as abnormal mechanical movement of torn meniscal tissue and the loss of the shock absorbing properties of the meniscus lead to destruction of the surrounding articular cartilage.
While this may be done arthroscopically, surgical repair using a suture has proven difficult to perform because of the hard-to-reach nature of the region and the difficulty in placing sutures in a way that compresses and secures the torn surfaces.

Embodiment Construction

[0061]In general, described herein are suture passer apparatus and methods of making and using them. Any of the suture passer apparatuses described herein may include features or elements that may be adapted for use with any of the other features or elements of the suture passers, except where specifically noted.

[0062]For example, described herein are suture passers that are particularly well adapted for insertion and manipulation in tight, narrow and difficult to access regions. Suture passers previously described, and illustrated in FIGS. 36A-36B, included an elongate body 3601 with a proximal handle region having controls for operating the apparatus. The distal end included a lower jaw member 3605 that is axially (distally-to-proximally) slideable relative to the elongate body, and an upper jaw member 3603 that is bent or bendable relative to the elongate body and / or the lower jaw. For example, the upper jaw may be pivotably attached 3613 to the end region of the elongate body 36...

Abstract

Described herein suture passer apparatus (devices and systems) that may be used to suture tissue within a narrow, confined space. In particular, described herein are suture passers having an elongate body and a lower jaw member that houses a tissue penetrator that is adapted to extend laterally from the lower jaw member and be deflected by a second jaw member? The second jaw member typically deflects the tissue penetrator either distally or proximally.
