  • Publication number: 20230019873
    Abstract: A method of generating a custom three-dimensional (3D) model of a patient bone from one or more 2D images is disclosed. The method includes obtaining a 2D image of a bone, optionally of a joint, and identifying a 3D bone template for a candidate or representative bone from a pre-aligned library of representative bones. The method further includes repositioning one or more views of the 3D model or 2D images (e.g., with respect to rotation angle or caudal angle). In an iterative process, another 3D bone model for another candidate bone can be identified based on the repositioning until an accuracy threshold is satisfied. When the accuracy threshold is satisfied, surface region(s) of the current 3D bone model can then be modified to generate the resulting 3D model for the patient bone. The process can then be repeated for other bone(s) associated with the joint of the patient.

  • Publication number: 20220409198
    Abstract: Anchor delivery systems include anchors having a generally cylindrical body with a rail on top for positioning within a delivery device slot. The rail incorporates a side-bulge as a retaining feature which axially extends along a majority of the length of the rail. The bulge interferes with a corresponding hourglass cutout in the delivery device slot to prevent the anchor from stripping out of the delivery device when the delivery device is retracted through tissue. The anchors are symmetrical along a length and width to facilitate loading within the delivery device. The distal portion of the delivery device includes a series of distally-extending barbs that intentionally change the penetration force required to push the device tip through tissue.
