Is an external device for receiving and positioning the male penis in a simulation of an erection to overcome impotence which includes a flexible hollow cylindrical body enclosed at one end and having the other end open for receiving the penis. After the penis is inserted into the cylindrical body, means are provided for introducing a negative pressure in the interior of the body and drawing the penis into the body to its anatomic limit to achieve an erection, the improvement comprising a sealing member integrally extending from the open end of the cylindrical body and comprising a thin-walled flexible sleeve-like sealing portion having a predetermined substantially constant inner circumferential measurement which is a function of the circumference of the stretched non-erect penile shaft, the predetermined inner circumferential measurement being less than the inner circumferential measurement of the cylindrical body for functioning as a seal about the penile shaft to maintain the negative pressure introduced therein, but not engaging the penile shaft tightly enough to restrict venous blood flow therein, and a flexible transition portion integrally interconnecting one end of the sleeve-like sealing portion and the open end of the body for positioning the sleevelike sealing portion in concentric axial alignment with the cylindrical body. |
