[0072] initial symmetrical weave

[0073] In one instance, the computing device is configured to determine needle layout and pattern knitting. In this regard, the computing device first takes two (2) principal dimensions: front to back (AP) length; and inside to outside (ML) width. Based on these dimensions (obtained from X-ray, MRI, CT or predictive modeling methods), an ellipse is constructed with n nodes equally spaced around a perimeter from +225 degrees (left) to -45 degrees (right).

[0074] Such as Figure 11 As shown in (a), twenty-five (25) nodes are used with a spacing of 11.25 degrees. This method was adapted from the initial sheep study (AP: 26mm, ML: 20mm) and scaled up (AP: 45mm, ML: 32mm). During the manufacture of the implant, a platform is constructed with holes at specific locations. Place the needle through the hole. Such as Figure 11 As shown in (b), an 86-pattern weaving method was used to fabricate the scaffold. Due to the fibers wrapped around th...

Abstract

Systems (500, 1000) and methods (1700) for fabricating a soft tissue implant (100, 400). The methods generally involve: receiving implant data representative of the target implant; determining a planned weaving path for forming the soft tissue implant; and communicating the planned weaving path to an output device.

Description

[0001] Cross References to Related Applications [0002] This patent application claims the benefit of US Provisional Application Serial No. 62 / 262,544, filed December 3, 2015, which is incorporated herein by reference. technical field [0003] The present invention relates to systems and methods for fabricating fibrocartilage, and in particular, to systems and methods for personalizing the structure of and forming implants. Background technique [0004] Meniscus injuries are common in the general population as a result of workplace accidents and sports-related activities, with an incidence ranging from approximately 60 to 70 cases per 100,000 individuals. Approximately 1.5 million knee arthroscopic procedures were performed, over 50% of which involved meniscus surgery. There are few alternative treatment options for extensive meniscal loss. An alternative treatment option is a meniscal allograft. While this procedure has proven promising for short-term results, long-term...
