Vascular embolization device and production method therefor

A vascular embolization device includes a coil with a primary shape and an stretch resistant wire provided inside the coil, in which the stretch resistant wire is a multilayer strand including at least one core layer and at least one outer layer including one or more resin compositions and a biochemical active material, and the core layer is composed of a material with a tensile break strength higher than that of the outer layer. The vascular embolization device has the function of administering a biochemical active material and also has good flexibility.

Occlusive implant compositions

Disclosed are methods of delivering an agent to the lumen of the vas deferens under guidance of ultrasound imaging. The methods include vas-occlusive contraception in which the vas deferens is non-surgically isolated and an occlusive substance is percutaneously administered into the lumen of the vas deferens under ultrasound. Also disclosed are methods of reversal of vas-occlusive contraception and methods of delivering an agent to the lumen of the vas deferens. Also disclosed are compositions for use in the methods of the invention.

Biomimetic nanofiber tissue scaffolds

A biomimetic tissue scaffold for repairing an elongated tissue in need of repair can comprise a plurality of coiled flexible polymeric ribbons having a surface on which is formed an array of nanofibers, the ribbons forming a tubular body defining a first open end in which a first end of the elongated tissue is receivable, a second open end in which a second end of the elongated tissue is receivable, and a lumen extending between the first and second open ends.

POLYHYDROXYL-CONTAINING POLYMER, PREPARATION METHOD THEREFOR AND USE THEREOF
20210309765 · 2021-10-07 ·

A polyhydroxyl-containing polymer has good biocompatibility, strong binding performance with substances the same surface of which contains oxygen, nitrogen, and so on and that easily form hydrogen bonds. A solution formed by the polymer adheres poorly to an intubation microcatheter, but adheres strongly to blood vessels, skin, and glass, and may be used as a vascular embolization agent.
