Patent number: 11925552Abstract: A stent device with skirt folds and a processing method thereof, a skirt folding method, and a heart valve. The stent device comprises a stent (1, 105) and a flexible skirt (2, 107), the skirt (2, 107) having an expanded state, in which the skirt is axially extended and surrounds the stent (1, 105) before release thereof, and a folded state, in which the skirt is driven by the deformation caused when the stent (1, 105) is released, collapses and folds axially along the released stent (1, 105) so as to form an annular peripheral leakage-blocking portion. The peripheral leakage prevention technology enables an interventional stent to fit to the inner wall of a vessel more snugly, such that the stent does not easily move and is more stable, thereby being suitable for more people, reducing additional risks of surgery and preventing complications such as peripheral leakage and thrombus.Type: GrantFiled: September 30, 2022Date of Patent: March 12, 2024Assignee: VENUS MEDTECH (HANGZHOU), INC.Inventors: Dajun Kuang, Jesse Jun Qi, Min Frank Zeng, Jincheng Yu, Lo Pham, Lai Nguyen

Patent number: 11926709Abstract: A method for recycling waste polyester, in particular to a method for recycling waste polyester by a modified alcoholysis method to recycle waste polyester to prepare dimethyl terephthalate (DMT), is provided and belongs to waste polyester recycling technology field. The waste polyester after dewatering and deoxygenation treatment is used as a raw material, in the step of feeding in melted state the alcoholysis agent is added in the melted waste polyester for preliminary alcoholysis, and the alcoholysis agent is ethylene glycol. On one hand, alcoholysis reaction occurs when the waste polyester raw material are melted, and at the same time, the viscosity of the melted material is reduced. Thus, the melted material remains melted at the alcoholysis temperature and is not easy to solidify again after entering the alcoholysis tank, ensuring that the alcoholysis is carried out under homogeneous conditions.Type: GrantFiled: September 7, 2020Date of Patent: March 12, 2024Inventors: Huayu Fang, Enbin Zhu, Dubin Wang, Guoqing Yu, Jincheng Chen, Tianyuan Li, Jiantong Wu, Jianhua Chen, Shengyao Lin

Publication number: 20210268151Abstract: A pre-loadable biological heart valve capable of rapid rehydration and a preparation method thereof. The preparation method comprises a cross-linking treatment, wherein a biological valve is cross-linked by soaking in an aqueous glutaraldehyde solution; a hydrophilic treatment, wherein the biological valve is soaked in a solution containing a hydrophilic molecule and a condensing agent, to allow the hydrophilic molecule to be immobilized on the biological valve by chemical grafting; and a drying treatment, wherein the biological valve after the hydrophilic treatment and the cross-linking treatment is dried to obtain a pre-loadable biological heart valve capable of rapid rehydration. The pre-loadable biological heart valve prepared by the preparation method of the present disclosure achieves rapid rehydration, and the crease can be quickly flattened after rehydration, bringing convenience during use.Type: ApplicationFiled: May 6, 2021Publication date: September 2, 2021Applicants: VENUS MEDTECH (HANGZHOU), INC., Sichuan UniversityInventors: Yunbing Wang, Gaocan Li, Yang Lei, Li Yang, Hou-Sen Lim, Dajun Kuang, Jincheng Yu

Publication number: 20210260247Abstract: A pre-loadable dried biological heart valve and a preparation method thereof. The preparation method includes: Step A: soaking a fresh animal pericardium in an aqueous solution of soluble elastin or glycosaminoglycan, and then subjecting the pericardium to a first cross-linking reaction in a mixed solution of carbodiimide or N-hydroxysuccinimide to allow the soluble elastin or glycosaminoglycan to bind to the pericardium via a chemical bond; and Step B: subjecting the pericardium after the first cross-linking to a second cross-linking reaction in an aqueous glutaraldehyde solution, and then drying the pericardium after the second cross-linking, to obtain the pre-loadable dried biological heart valve. The dried biological heart valve obtained by the above preparation method has good toughness, and is rapidly flattened out in a simulated folding and pressing test.Type: ApplicationFiled: May 6, 2021Publication date: August 26, 2021Applicants: VENUS MEDTECH (HANGZHOU), INC., Sichuan UniversityInventors: Yunbing Wang, Yang Lei, Gaocan Li, Li Yang, Hou-Sen Lim, Dajun Kuang, Jincheng Yu
