AI Technical Summary
Soft tissues, tendons, and ligaments, such as the ACL and MCL, often fail to heal properly due to the inhibition of fibrin clot formation within synovial joints, leading to joint degeneration and limited functionality in patients.
Development of an implant device with preformed channels and preloaded sutures, made from materials like collagen, to facilitate secure connection and stabilization of tissue repairs, utilizing a substrate that can absorb blood to form a clot and scaffold for healing.
The implant device enhances tissue repair by maintaining a blood clot at the wound site, promoting healing through growth factors and proteins, while minimizing damage during suture loading and ensuring stable tissue connections.

Abstract
Description
[Background technology]
[0001] [Citation to Related Applications] This application claims priority to and the benefit of U.S. Provisional Patent Application No. 63 / 217,197, filed June 30, 2021, which is incorporated by reference in its entirety.
[0002] Soft tissues, tendons, and / or ligaments may be injured during sports activities, strenuous exercise, physically demanding work, and / or normal, everyday physical activities. However, this injury is inevitable, and patients who have suffered such injuries may be restricted, perhaps significantly, from employment functioning, sports activities, physical activity participation, and / or some social involvement.
[0003] Patients with such injuries may typically seek surgical intervention to repair such damage. While soft tissues, tendons, and / or ligaments, particularly the anterior cruciate ligament (ACL), medial collateral ligament (MCL), Achilles tendon, and meniscus, may heal adequately and / or completely on their own, this may not be the case. For example, if a natural clot / scaffold develops at all, the clot / scaffold may not develop in a timely or structurally appropriate manner.
[0004] Tissues found outside of joints heal by forming fibrin clots that connect broken tissue ends together and then remodel to form scars that heal the tissue. Inside the synovial joint, fibrin clots either fail to form or dissolve quickly after knee joint trauma, thus preventing joint degeneration and stiffness after minor trauma. Joints contain synovial fluid that naturally prevents clot formation within the joint as part of normal joint activity. This fibrinogen degradation process results in premature loss of the fibrin clot scaffold and disruption of the healing process for tissues within the joint or intra-articular tissue. Surgical procedures to repair such trauma / injuries may involve removing the damaged tissue and replacing it with a point-to-point tissue graft. Summary of the Invention

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0034] For the purposes of promoting an understanding of the principles of the present disclosure, reference will now be made to the embodiments illustrated in the drawings, and specific language will be used to describe the same, nevertheless it will be understood that no limitation of the scope of the present disclosure (invention) is thereby intended.
[0035] Described herein is the art of an implant device that may be configured to repair tissue. FIG. 1 is an exemplary diagram of an implant device. Referring to FIG. 1, an implant device 102 may have a distal end 104 that may be configured to be connectable to at least a first portion of tissue (not shown). The device may have a distal end 106 that may be configured to be connectable to at least a second portion of tissue (not shown). The device may have a base or substrate 108 that may be configured to form an interface between the first portion of tissue and the second portion of tissue. The implant device 102 may have a longitudinal axis that may extend between the distal end and the proximal end within the base.
[0036] The substrate 108 may be porous and / or may absorb blood. The implant device 102 may immobilize autologous blood within the tissue wound site. The patient's blood may (e.g., spontaneously) form a clot and / or a (e.g., temporary) scaffold. The implant device 102 may protect the clot and / or maintain the clot within the tissue wound site. The clot may release wound healing growth factors and / or proteins that may help heal the damaged tissue. The implant device 102 may keep the blood within the tissue wound site and / or protect the blood from being prematurely washed away.
[0037] The implant device 102 can have at least one preformed channel (not shown) disposed in the substrate 108. The implant device 102 can have at least one suture (not shown) that can be at least partially preloaded into the at least one channel. In one or more scenarios, the implant device 102 can be configured such that the tissue for repair can be, for example, soft tissue, tendons, and / or ligaments, among other tissues.
[0038] In one or more scenarios, the substrate 108 may be comprised (e.g., partially and / or substantially) of, for example, collagen (e.g., human, porcine, bovine, equine, avian, fish, etc.), bovine (e.g., subcutaneous) connective tissue, and / or extracellular matrix proteins. In one or more scenarios, the substrate 108 may be comprised of one or more substances that may be saturable by human blood (e.g., 10 milliliters (mL) of a patient's blood). While dimensions may vary for a variety of reasons, an exemplary implant device 102 and / or substrate 108 may be approximately 45 millimeters (mm) in length along a longitudinal axis and approximately 22 mm in diameter.
[0039] In one or more scenarios, the implant device 102 may be (e.g., partially and / or substantially) cylindrical, (e.g., partially and / or substantially) oval (not shown), (e.g., partially and / or substantially) round (not shown), (e.g., partially and / or substantially) rectangular (not shown), (e.g., partially and / or substantially) square (not shown), or (e.g., partially and / or substantially) trapezoidal (not shown), among other shapes.
[0040] It may be useful to provide one or more preformed channels in the implant device 102 and / or to provide the implant device 102 with one or more preformed channels so that a surgical suture, for example, can be threaded through the one or more preformed channels. For example, the one or more preformed channels of the implant device 102 may facilitate the insertion / loading of a surgical suture into the implant device 102 that can be used to connect the implant device 102 to damaged tissue. The one or more preloading channels may facilitate avoiding damage to the implant device 102 during loading of a suture without the one or more preloading channels.
[0041] Techniques that allow for pre-loading of one or more sutures into the implant device 102 and / or provide the implant device 102 with one or more pre-loaded sutures may be useful. For example, one or more sutures at least partially pre-loaded into the implant device 102 can facilitate coupling of the implant device 102 to, for example, damaged tissue. The one or more pre-loaded sutures can facilitate avoiding damage to the sutures during loading of the implant device 102 and / or the sutures without the one or more pre-loaded sutures.
[0042] In one or more scenarios, the at least one preformed channel (not shown) may be formed during formation of the implant device 102 and / or at a time (e.g., substantially) proximate in time to post-shaping of the implant device 102. In one or more scenarios, the at least one suture (not shown) may be a #2 absorbable suture or may be a #2 suture. For example, a #2 Ethibond suture may be used, among other suture types and / or sizes.

[0056] 6 is an illustration of a mold (e.g., an injection mold) for molding an implant device using one or more methods. With reference to FIG. 6, the one or more methods may include providing a (e.g., injection mold) mold 602. The mold may have an interior space 604. The one or more methods may include placing one or more needle-like elements 606 within the interior space 604. The needle-like elements 606 (e.g., each) may have a first end that extends outside the interior space 604. The one or more methods may include injecting / adding a substrate-forming material (not shown) into the interior space 604.
[0057] In one or more scenarios, the injection / addition of the substrate forming material may be performed under pressure or without pressure (e.g., gravity feed), perhaps for example to speed up / control the injection / addition / filling. The injection / addition of the substrate forming material may be performed at a temperature below 37° C., for example between 0° C. and 10° C. In one or more scenarios, the viscosity of the substrate forming material may provide information regarding the injection / addition / filling process.
[0058] The one or more needle elements 606 can provide one or more negative molding voids within the interior space 604. One or more methods can include processing or treating (e.g., freezing, etc.) the formed substrate to form an implant device (not shown). In one or more scenarios, the viscosity of the substrate forming material can be adjusted (e.g., increased to a "gel-like consistency," among other consistencies) by heat treatment, for example at 37° C. (e.g., 20° C.-40° C.), for a period of time, for example, 2-4 hours (e.g., 15 minutes-12 hours). In one or more scenarios, the viscosity adjustment can be based on other techniques, including energy transfer into the mold 602, which results in thermal energy that can increase the viscosity (e.g., "gelation" etc.).
