CATHETER FOR THE TRANSFER OF HUMAN EMBRYOS WITH SECTION OF TRANSVERSE FOLDS AND ERGONOMIC HANDLE

摘要

This innovation refers to a catheter for the transfer of human embryos. These catheters should have the ability to adjust either automatically or by the operating clinician to the desired shape and angle, so that their entry and passage inside the outer cervical os, the cervical channel and the intrauterine cavity is facilitated. The proposed catheter has an integrated element of transverse folds in the shape of an "accordion", which is able to be configured in a way to facilitate the passage of the catheter inside the cervical channel and intrauterine cavity. The proposed catheter has the following advantages. Firstly, it is flexible at a specific section, so that it can automatically and on its own manage the shape of the cervical channel and navigate through it. Secondly, it can be configured to and maintain the desired shape and angle given to it by the operating clinician, in order to achieve an easier, faster and without micro-injuries entry and passage inside the cervical channel and intrauterine cavity. Thirdly, it makes possible the re-configuration of its shape and angle by the operating clinician if deemed necessary. Finally, the configuration at the section of transverse folds is achieved without narrowing the lumen of catheter (α) as to affect the functionality of catheter (β).
