METHOD OF EXTRACORPORAL FERTILISATION Russian patent published in 2010 - IPC A61B17/435 A61K38/24 A61K31/573 A61P15/08 A61B1/05 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, in particular to gynecology, and deals with extracorporal fertilisation. After induction of superovulation for puncture of follicle into vagina cavity introduced is heated to body temperature tubular element with ball-like tip, which has guide canal on axis for puncture-biopsy needle. By means of it respective side of posterior vaginal fornix is pressed into abdominal cavity for maximally possible distance. Ovary is moved with side of mature follicles to contact of selected mature follicle with posterior fornix wall. Follicle centre is superposed with axis of tubular element canal, follicle is fixed in said state, distance from place of puncture of vaginal mucous membrane from the side of its cavity to follicle centre is determined and needle is moved out of the canal for said distance. After that follicular fluid is aspirated.

EFFECT: method ensures targeted puncturing of follicle centre, which results in reduction of traumaticity and increase of extracorporal fertilisation efficiency.
