Abstract

The disobstructor dilator device (1) is employed in the urinary obstructive pathology of the cervico-urethral portion of the male, in order to ensure the openness of the urethral channel between the vesical neck and the striated sphincter of the urethra. The device (1) consists of a tubular body (101) open at its ends, in which the lower end presents a section which is greater than the upper end. At the upper end there are provided anchoring elements (2) having the shape of hooks, which are intended to cooperate with the vesical neck (12).

Claims

1. A dilator device employed in the urinary tract of male to ensure the openness of the urethral channel in the cervicourethral zone between the vesical neck and the striated sphincter of the urethra, comprising a tubular body open at its ends, said ends being designated as the upper end and the lower end with reference to the position of the device in place applied to the patient in upright position, said tubular body having a length which is smaller than the distance between the vesical neck and the striated sphincter, in which the lower end has a greater cross section than that of the upper end, and anchoring means intended to cooperate with the vesical neck, being provided at the upper end of said tubular body.

2. A dialator device according to claim 1, wherein the tubular body is shaped substantially like the frustum of a cone.

3. A dialator device according to claim 1, wherein the anchoring elements consist of elastic hooks arranged along the circumference of the upper end of the tubular body.

4. A dialator device according to claim 3, wherein there are at least two hooks.

5. A dialator device according to claim 4, wherein there are four hooks arranged by diametrally opposed pairs, the angular distance between the hooks of each pair being between 45°

and 15°

.

6. A dialator device according to claim 5, wherein the angular distance between the hooks of each pair is of 25°

.
