Abstract

A method for removably implanting in an implantable zone of a human body, preferably a vein, a divisible and flexible stem is disclosed. The stem includes a distal end and a proximal end, and may further includes a medical apparatus or implant fixed to one end of the stem. The method includes forming an access route to an implantation zone in a human body, followed by introducing a medical apparatus or implant into the body through the access route with the distal end of the stem first so as to implant the apparatus in the implantation zone, the stem having a length sufficient to extend along the route. The method further includes providing a locating member on a proximal end of the stem, the member being adapted to being disposed subcutaneously for locating the stem through the skin of the patients body. Thereafter, the locating member and the proximal end of the stem are disposed subcutaneously in the body in proximity to the access route. The step of disposing includes forming within the patients body in proximity to the access route, a small space for disposing therein the locating member fixed to the proximal end. After temporary implanting an implant, a removable strengthening cable can be inserted in the stem in order to displace the implant along the sheath during its positioning in an implantable zone such as a vein, in particular in the inferior vena cava of a patient. This implant can be easily removed after a certain period, when the risks of pulmonary embolism for example, is no longer feared. In the present invention, the medical apparatus may include at least one of a stent and a drug delivery means.
