Bored hollow lumen
11576797 · 2023-02-14 · ·

A manufacturing process forms a bored hollow lumen. The manufacturing process includes providing a solid rod of a bioresorbable material and boring a hole axially through the solid rod. The manufacturing process also includes modifying surface defects formed on a luminal surface by the boring, the luminal surface defining the hole, thereby forming the bored hollow lumen. A bored hollow lumen includes a lumen wall including a bioresorbable material. The lumen wall has an abluminal surface and a luminal surface. The luminal surface defines a bore through the bored hollow lumen. The bioresorbable material has a uniform crosslinking density.

THERMAL PROCESSING OF POLYMER SCAFFOLDS

Methods are disclosed including thermally processing a scaffold to increase the radial strength of the scaffold when the scaffold is deployed from a crimped state to a deployed state such as a nominal deployment diameter. The thermal processing may further maintain or increase the expansion capability of the scaffold when expanded beyond the nominal diameter.

ENVIRONMENTALLY FRIENDLY DRY CLEANING BAGS AND METHODS OF MAKING SAME
20180009148 · 2018-01-11 ·

A method of manufacturing a biodegradable dry cleaning bag is disclosed, the method including loading an environmentally friendly slurry into a hopper, extruding the environmentally friendly slurry, passing the environmentally friendly slurry through a die, inflating the environmentally friendly slurry into a cylindrical shape, thereby creating a cylindrical member, passing the cylindrical member over a first roller, and rolling the cylindrical member onto a roll.

IMPROVED IMPLANTABLE PLATE AND METHOD OF MANUFACTURING THEREOF

The present invention concerns a method for obtaining an implantable plate for healing a fractured joint of a patient, comprising the steps of: 1) providing a 3D representation of a bone structure in a zone around a joint fracture, the zone comprising essentially all fragments of broken or ruptured bones and at least the ends of unbroken bones which form part of the fractured joint; 2) identifying different bone fragments within said 3D representation; 3) simulating a reduction of said bone fragments into a full joint; 4) calculating optimal parameter values for an implantable plate; 5) obtaining the implantable plate taking into account the calculated parameter values, whereby in step 3, the reduction is simulated by automatedly fitting positions and orientations of said bone fragments to a 3D representation of a healthy joint of said patient.

THREE-DIMENSIONAL PRINTING

An example of a three-dimensional (3D) build material composition includes from about 70 wt % to about 95 wt % of polyamide particles, based upon a total weight of the build material composition; and from about 5 wt % to about 30 wt % of biodegradable polyester filler particles, based upon the total weight of the build material composition. The biodegradable polyester filler particles are present in the build material composition without any additional filler particles.

20230023495 · 2023-01-26 · ·

Disclosed is a support material for a fused deposition modeling. The support material has excellent adhesion to a variety of model materials and is easily dissolved and removed by washing with water. Also, the waste liquid (PVA-based aqueous solution) generated after the washing operation may be allowed to be drained as it is, in compliance with environmental regulations. The support material comprises (A) PVA-based resin having a group containing sulfonic acid or a salt thereof and (B) biodegradable polyester. The (A) PVA-based resin having a group containing sulfonic acid or a salt thereof and (B) biodegradable polyester have a sea-island structure in which one is dispersed in the other as a matrix.

Cellulose Ester Composition and Process For Producing Articles Therefrom
20230226734 · 2023-07-20 ·

A process is disclosed for combining a cellulose ester polymer with a plasticizer. The cellulose ester polymer is in the form of particles and is combined with a wetting agent and the plasticizer while mixing. The wetting agent dramatically improves the ability of the cellulose ester particles and plasticizer to form a homogeneous mixture. During melt processing, in one embodiment, the wetting agent is volatilized and does not remain in the final product.
