Apparatus and method for continuously producing reinforced plastic pipe using transfer film
11383467 · 2022-07-12 ·

An apparatus and a method enable continuous production of a reinforced plastic pipe using a transfer film. The transfer film moves at a predetermined speed in the longitudinal direction and is arranged to be in close contact with a circumferential surface of a base mold which winds glass fiber wound around the outer circumferential surface thereof using a filament winding method to mold a reinforced plastic pipe, such that the reinforced plastic pipe molded with the moving transfer film is moved forward, thereby being capable of continuously producing a reinforced plastic pipe with a desired length without breakage. The apparatus includes a rotary axial pipe; a base mold; a transfer film feeding part; and a transfer film withdrawing part. The method for continuously producing a reinforced plastic pipe includes a transfer film adhering step; a transfer film forced moving step; and a pipe cutting and separating step.

Bioresorbable scaffold having sustained drug delivery
11147696 · 2021-10-19 ·

A multilayer bioresorbable stent having sustained drug delivery is disclosed herein. The bioresorbable stent releases a therapeutic substance from the body of the bioresorbable stent starting when the bioresorbable stent is implanted within an anatomical lumen and ending when the entire mass of the bioresorbable stent is no longer present within the anatomical lumen. The bioresorbable stent releases the therapeutic substance gradually during the treatment as the mass of the each layer of the bioresorbable stent erodes. Methods of making the therapeutic layers within the bioresorbable sent are further disclosed. Sustained drug delivery reduces the risk of late and very late stent thrombosis.

Container

A container, in particular in ampoule form, and consists entirely or predominantly of plastic materials and has a container body (10) for receiving a filling product (12). The filling product can be removed via a releasable container opening (22) after a closure part (18) has been removed, which closure part is detachably connected to the neck part (14) of the container body (10) along a separation line (20) in an unopened position. In the unopened position, a conically extending wall (36) on the neck part (14) on the container body (10) and a conically (38) or cylindrically extending wall (38a) on the closure part (18) adjoin the separation line (20). These walls (36, 38, 38a) delimit at least part of an annular space (40, 40a), one end of which opens out into the environment and the other end of which opens out into the separation line (20).

Curved heat shrink tubing and methods of making the same
11034079 · 2021-06-15 · ·

Curved heat shrink tubing and methods of making the same are described herein. An example method includes inserting heat shrink tubing into a tube, curving the tube, and deforming the heat shrink tubing, inside of the tube, to have a curved shape along a length of the heat shrink tubing where a first length of the heat shrink tubing along an outer radius of the curved shape is longer than a second length of the heat shrink tubing along an inner radius of the curved shape.

Method for precise control of manufacture of non-rigid thin-walled tube products

A method for correcting non-rigid thin-walled tubular elements having geometric deficiencies, wherein, following correction, the tubular elements may perform over a wide range of pressure and temperatures, for example as a rocket motor beaker, from about −70 C to about 1000 C. Correction is required to remove asperities, maximize cylindricity, squaring a forward end wall and a rearward end wall, so that the forward end wall of the tube product may be fitted, bonded and sealed to a circular planar element using a labyrinth-joint closure. The method provides uniformity so that both the tubular elements and the circular planar elements are interchangeably uniform in size, shape and performance, and may be readily assembled into non-rigid thin-walled tube products.

INTRALUMINAL VASCULAR DEVICE, PARTICULARLY FOR SCLEROTHERAPY, AND METHOD
20230404606 · 2023-12-21 ·

A vascular device for treating a tract of a blood vessel has an intraluminal element having at least one dispensing opening for dispensing a pharmacological agent in the tract of the blood vessel, and an abrasion element coming into contact with an inner wall of the blood vessel to remove material from the inner wall. The abrasion element has a contact portion for removing the material and a collection portion for collecting the removed material. and is configured to expand between a rest configuration and a contact configuration. The abrasion element has a first surface facing the intraluminal element and configured to face a fluid inside the blood vessel. The first surface in the contact configuration forms a concave portion adapted to face the fluid inside the blood vessel. The collection portion includes the concave portion to collect the material removed from the inner wall treated with the pharmacological agent.

Crimping methods for thin-walled scaffolds

A medical device includes a balloon expanded scaffold crimped to a catheter having a balloon. The scaffold has a network of rings formed by struts connected at crowns and links connecting adjacent rings. The scaffold is crimped to the balloon by a process that includes using protective polymer sheaths or sheets during crimping, and adjusting the sheaths or sheets during the crimping to avoid or minimize interference between the polymer material and scaffold struts as the scaffold is reduced in size.
