HAR-1 In one embodiment, the distal end 120, or a part of the distal end 120, such as a surface of the distal end 120, may serve as an engagement feature 140. The engagement feature 140 maintains contact between the fixation device 100 and a part of the body in response to tension applied to the tissue 114 in the second direction 118 opposite the first direction 116. As the tension applied to the tissue 114 in the second direction 118 increases the pressure that the engagement feature 140 applies to the part of the body in contact with the engagement feature 140 increases. 29 Added by DJM 9 2021 9/2/21, 12:00 AM

HAR-1 Next, the surgeon slides 610 the tissue graft through the opening 112 in a first direction 116 such that one or more teeth 220 within the opening 214 engage the tissue graft and the one-way tissue fixation device (e.g., fixation device 400) contacts bone (e.g., the cortex) at the proximal end of the bone tunnel 416. 62 Added by DJM 9 2021 9/2/21, 12:00 AM

HAR-1 Next, the surgeon threads 608 the tissue graft through an opening in the fixation device. For example, in one embodiment, a surgeon may pass a free end of the tissue through the opening 414 starting from the distal end 410 and threading 608 the tissue 408 through until the free end exits the fixation device 400 at the proximal end 412. 61 Added by DJM 9 2021 9/2/21, 12:00 AM

HAR-1 Next, the surgeon fixes 606 the tissue graft at a first end of the bone tunnel 416 (e.g., at a distal end of the bone tunnel 416). Conventional tools and techniques may be used to deploy tissue graft within the bone tunnel 416. Alternatively, or in addition, a fixation device according to the embodiments disclosed herein may be used to fix 606 the tissue graft at the first end of the bone tunnel 416 (e.g., the distal end). 60 Added by DJM 9 2021 9/2/21, 12:00 AM

HAR-1 Figure 6 illustrates one example of a method 600 for securing tissue within, or to, a body part of a patient, according to one embodiment. Referring to Figures 4 and 6, the method 600 starts with a user, such as a surgeon, forming 602 a bone tunnel 416 within a bone of a patient. Conventional tools and techniques may be used to form the bone tunnel 416. Next, the surgeon deploys 604 a tissue graft within the bone tunnel 416. A tissue graft is one example of a tissue that can be used with embodiments of the disclosed solution. Conventional tools and techniques may be used to deploy tissue graft within the bone tunnel 416. 59 Added by DJM 9 2021 9/2/21, 12:00 AM

HAR-1 Figure 5F is an end view of a one-way tissue engagement feature, according to one embodiment. Figure 5F illustrates a different type of one-way tissue engagement feature. The one-way tissue engagement feature may include a single tooth 510 that extends from a wall of an opening 512 in the fixation device 500f. The single tooth 510 may extend beyond a radius of the opening 512. The single tooth 510 may be shaped as a polygon with a broad base and a flat top that does not come to a point. 58 Added by DJM 9 2021 9/2/21, 12:00 AM

HAR-1 Figure 5E is an end view of a one-way tissue engagement feature, according to one embodiment. Figure 5E illustrates a different type of one-way tissue engagement feature. The one-way tissue engagement feature may include four teeth 508 that extend from a wall of an opening in the fixation device 500e. The teeth 508 may be align longitudinally within the opening or may be offset with respect to each other. The teeth 508 have be shaped as a polygon with a broad base and a flat top that does not come to a point. 57 Added by DJM 9 2021 9/2/21, 12:00 AM

HAR-1 Figure 5D is a side perspective view, end perspective view, opposite end perspective view, and a side perspective view of a fixation device 500d having a square longitudinal cross-section in four different orientations, according to one embodiment. Or course, other polygonal longitudinal cross-sections can be used to implement embodiments of the solution in this disclosure. In the illustrated embodiment, the teeth 502 are shaped to come to a point. From left to right, the first orientation is with the fixation device 500d on its side. The next orientation shows the fixation device 500d from the proximal end 212. The next orientation shows the fixation device 500d from the distal end 210. The next orientation shows the fixation device 500d standing on end. 56 Added by DJM 9 2021 9/2/21, 12:00 AM

HAR-1 The embodiment of Figure 5C includes an engagement feature 506 integrated into the body of the fixation device 500c. In certain embodiments, the engagement feature 506 is a shoulder formed in a wall of the body and circumscribing the opening. The shoulder may be sized to engage the cortex of a bone to fix a tissue and the fixation device 500c to the bone. 55 Added by DJM 9 2021 9/2/21, 12:00 AM

HAR-1 Various surgical procedures in people and animals include a fixation step, procedure, use of a device (also referred to as a fixator), of the like. The fixation feature, or function, may be between two pieces of bone, soft tissue and bone, soft tissue and hard tissue, soft tissue and soft tissue, and/or a combination of these. Unfortunately, many known fixation techniques, steps, procedures, devices, or components are complicated, involve multiple parts, are not easy to revise, become loose over time, are difficult to tension, and have other limitations. 2 Added by DJM 9 2021 9/2/21, 12:00 AM
