17 results about "Vas deferens" patented technology

The vas deferens (Latin: "carrying-away vessel"; plural: vasa deferentia), also called ductus deferens (Latin: "carrying-away duct"; plural: ductus deferentes), is part of the male reproductive system of many vertebrates; these ducts transport sperm from the epididymis to the ejaculatory ducts in anticipation of ejaculation. It is a partially coiled tube which exits the abdominal cavity through the inguinal canal.

A comprehensive surgical clip for improved vasectomy and its operation method

ActiveCN116350420BFallopian occludersAgainst vector-borne diseasesPre-operative evaluationVas deferens
The present invention relates to a comprehensive surgical clip for improving vasectomy and an operating method thereof, comprising a comprehensive surgical clip; the comprehensive surgical clip comprises two clamps for clamping and fixing the two ends of the vas deferens, the two clamps being connected to the same scissors structure and being synchronously opened and closed by the scissors structure; and further comprising: a syringe, which is obliquely and slidably arranged on the comprehensive surgical clip and is used for injecting a mixed liquid into the vas deferens and promoting the discharge of semen. The present invention has a compact and reasonable structure and is easy to operate. By adopting a special surgical clip and a specific operating technique, work efficiency is improved. At the same time, on the basis of traditional vasectomy surgery, a special flushing technology is added to improve the efficiency of residual semen discharge, greatly shortening the patient's postoperative contraception time compared with traditional surgery, and can also judge the patency of the vas deferens according to the color of the discharged semen, providing preoperative evaluation guidance for some patients who need to restore fertility and undergo vasectomy.

Methods for reversible male birth control

ActiveUS12496270B2Organic active ingredientsPharmaceutical delivery mechanismVas deferensDeferent duct
Contraceptives and methods for reversible male birth control are disclosed herein. One method includes providing a polymer including a viscosity and reducing the viscosity of the polymer to create a polymer solution. The method further includes injecting the polymer solution into the vas deferens of a male subject while the viscosity of the polymer is reduced. The polymer solution forms a polymer barrier in the vas deferens to physically block the outflow of sperm in the vas deferens subsequent to injection.
