Abstract: This invention concerns a device for gynaecological transfer or insemination with shape memory comprising a catheter comprising a polymer tube open at its ends, characterised in that this tube is comprised of a medium-density polymer associated with mineral filler. Such a device presents an adaptable diameter and a structure not enlarged by the presence of a metallic mesh without imposing fastidious handling such as can be the case of a flexible introducer catheter associated with a metallic rod for positioning.
