Abstract
A dilating device for the prostatic urethra comprising: at least three, laterally connected ridges, wherein each ridge is configured to longitudinally engage with a different substantially longitudinal groove of the prostatic urethra of a patient, and wherein the at least three laterally connected ridges are configured to laterally compress to enable insertion into the prostatic urethra in a compressed configuration, and wherein the at least three laterally connected ridges are configured to laterally expand to a normally-open configuration upon deployment within the prostatic urethra, to exert a radially outwards force that dilates the prostatic urethra.
Claims16
A dilating device for dilating a prostatic urethra, the device comprising:
- a central ridge longitudinally oriented and positioned on an anterior peripheral edge of the dilating device to engage an anterior inter-lobar groove of the prostatic urethra;
- and
- a first closed form positioned on a first side of the central ridge including a first peripheral ridge;
- said first peripheral ridge forming a postero-lateral edge of the device on said first side of the central ridge;
- a second closed form symmetrically positioned on a second side of the central ridge laterally opposite said first side;
- said second closed form including a postero-lateral second peripheral ridge;
- said second peripheral ridge forming a postero-lateral edge of the device on said second side of the central ridge;
- wherein the dilating device is configured to be laterally expandable in the prostatic urethra to a normally-open configuration wherein
- said first peripheral ridge is extended away from said central ridge by
- a first distal connector connecting a distal portion of the first peripheral ridge to a distal portion of the central ridge and
- a first proximal connector connecting a proximal portion of said first peripheral ridge to a proximal portion of the central ridge, and
- said second peripheral ridge extended away from said central ridge by
- a second distal connector connecting a distal portion of the second peripheral ridge to said distal portion of the central ridge and
- a second proximal connector connecting a proximal portion of said second peripheral ridge to said proximal portion of the central ridge;
- such that said first distal connector and said second distal connector form lateral edges of a distal cross section of the dilating device, the lateral edges connected on their anterior ends to said central ridge of the device;
- wherein in said normally-open configuration, a posterior side of said dilating device is open;
- and said first peripheral ridge delimits a first edge of the posterior opening of the dilating device and said second peripheral ridge delimits a second edge of the posterior opening of the dilating device on an opposite lateral side of said posterior opening from said first edge;
- wherein each of said first closed form and said second closed form is laterally compressible to a compressed configuration configured for insertion into the prostatic urethra.
