Devices, systems and methods for treating benign prostatic hyperplasia and other conditions

Abstract

Extra-urethral implants and methods of use are disclosed. Implants can treat disorders or diseases of the prostate by, for example, enlarging the lumen of the prostatic urethra.

         23 . A system for implantation in a lumen of a urethra, comprising:
 a delivery device configured to carry and deliver an implant; and   an implant having a non-circular cross-sectional shape such that the cross-sectional shape substantially conforms to the cross-sectional shape of the urethra.   
     
     
         24 . The system of  claim 23  wherein the non-circular cross-sectional shape of the implant is a triangular shape. 
     
     
         25 . The system of  claim 23  wherein the implant is configured to have a first configuration to a second configuration. 
     
     
         26 . The system of  claim 25  wherein the first configuration is a constrained configuration and the second configuration is an expanded configuration. 
     
     
         27 . The system of  claim 25  wherein the implant self-expands from the first configuration to the second configuration. 
     
     
         28 . The system of  claim 25  wherein the delivery device causes the implant to change from the first configuration to the second configuration. 
     
     
         29 . The system of  claim 23  wherein the implant is configured to provide an outward radial force on the urethra. 
     
     
         30 . The system of  claim 25  wherein the implant is configured to provide an outward radial force on the urethra in the second configuration. 
     
     
         31 . The system of  claim 26  wherein the implant is configured to provide an outward radial force on the urethra in the expanded configuration. 
     
     
         32 . An implant for treating a urethral lumen, comprising a plurality of legs arranged in triangular shape, wherein the implant has a delivery configuration and a deployed configuration. 
     
     
         33 . The implant of  claim 32  wherein the delivery configuration has a smaller cross-section than the deployed configuration. 
     
     
         34 . The implant of  claim 32  wherein the implant self-expands from the delivery configuration to the deployed configuration. 
     
     
         35 . The implant of  claim 32  wherein the implant is expanded from the delivery configuration to the deployed configuration using a delivery tool. 
     
     
         36 . The implant of  claim 32  wherein the implant is configured to provide an outward radial force on the urethra. 
     
     
         37 . The implant of  claim 32  wherein the implant is configured to provide an outward radial force on the urethra in the deployed configuration.
