Abstract
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 Analysis
Total Claims: 7
Claim 1
Independent Claim
126 words
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.
Claim 2
Dependent Claim
