At least part of the locking member is held to the receiving part between the downwardly and upwardly facing surfaces, and wherein the receiving part and the locking member are only separable from one another by permanently deforming or damaging at least one of the receiving part or the locking member.

METHOD OF PRODUCING INJECTION MOLDED ARTICLES
20230045578 · 2023-02-09 ·

Injection molded articles and methods of making injection molded articles. The methods include the use of a first plasticizing unit and a second plasticizing unit on a common frame feeding a first mold and a second mold on the common frame. Separating the production of each part of a two-part article into separate plasticizers and molds allows for the tuning of production parameters on a per-part basis, improving part flatness and part-to-part weight variance.

Soft Tissue Graft Preparations and Methods of Use

In one embodiment, the present disclosure may be a method for preparing a soft tissue graft, comprising: passing a suture material through the soft tissue graft adjacent to a graft support filament at a first longitudinal location along the filament and graft, such that the suture material passes through the graft on a first side of the filament; passing the suture material over the filament and back through the graft adjacent to the filament at a second longitudinal location spaced longitudinally along the filament and graft from the first longitudinal location, such that the suture material passes through the graft on the first side of the filament; and tensioning the suture material to secure the filament to the graft along a length of the suture material between the first longitudinal location and the second longitudinal location.

NON-BRAIDED BIODEGRABLE FLOW DIVERTING DEVICE FOR ENDOVASCULAR TREATMENT OF ANEURYSM AND ASSOCIATED FABRICATION METHOD
20230039246 · 2023-02-09 ·

A biodegradable flow diverting device (BFDD) that will regulate blood flow into an aneurysmal sac, act as a scaffold for endothelization at the neck of an aneurysm, and degrade after successful dissolution of aneurysm and remodeling of blood vessel. This BFDD and associated fabrication method have the following features: (1) This is a non-braided FDD. The pore shapes, sizes, architectures (especially at the inlet and outlet of the pores), pore densities and porosities can be controlled for the optimum performance depending on the blood vessel and aneurysmal morphologies from patient MRI images, (2) BFDD is developed on a rotary arm with programmable variable speed and diameter in conjunction with a micromotion stage (3) Fabrication system can take any material including blended/composite biomaterials by adjusting temperature of the electro-melt extruder/needle and (4) Fabrication system is compatible with CAM (computer aided manufacturing) software and able to operate based on the adapted G-code.
