An implant delivery system can be configured to deliver an inflatable implant into a bladder via a urethra. The delivery system can comprise an elongate tubular body, an inflation tube and an implant decoupler. The tubular body can comprise a central lumen configured to hold an inflatable implant in an initial un-inflated state for delivery of the implant into the bladder. A method of use can include passing a distal tip of the elongate tubular body into the bladder. The implant can be inflated and released into the bladder.

1. An implant delivery system configured to deliver an inflatable implant into a bladder via a urethra, the delivery system comprising: an elongate tubular body sized to pass through a urethra into a bladder, the tubular body comprising: a central lumen configured to hold an inflatable implant in an initial un-inflated state for delivery of the implant into the bladder;an atraumatic tip at a distal most end; anda lateral opening in a sidewall of the elongate tubular body, the lateral opening positioned proximally from the atraumatic tip and operable to deliver the inflatable implant laterally from the central lumen and into the bladder away from a wall of the bladder;an inflation tube positioned within the central lumen of the tubular body, the inflation tube configured to couple with the inflatable implant to allow inflation of the inflatable implant from within the tubular body; andan implant decoupler positioned within the central lumen of the tubular body around the inflation tube, the implant decoupler configured to decouple the inflatable implant from the inflation tube after inflation of the inflatable implant from the un-inflated state to an inflated state. 2. The implant delivery system of claim 1, further comprising a syringe in fluid communication with the inflation tube. 3. The implant delivery system of claim 2, further comprising a quantity of gas within the syringe. 4. The implant delivery system of claim 3, further comprising a quantity of liquid within the syringe. 5. The implant delivery system of claim 4, wherein the liquid is at least one of a high vapor pressure medium and a therapeutic agent. 6. The implant delivery system of claim 4, wherein the liquid is a high vapor pressure medium that is a mixture of one or more PFCs. 7. The implant delivery system of claim 1, further comprising the inflatable implant. 8. The implant delivery system of claim 7, wherein when in the initial un-inflated state within the central lumen, the inflatable implant is compressed, folded and coupled to the inflation tube. 9. The implant delivery system of claim 1, further comprising at least one of a flap, door or retractable cover configured to be positioned over the lateral opening. 10. The implant delivery system of claim 1, further comprising a depth stop configured to provide visual and/or tactile feedback of when the lateral opening in the elongate tubular body is within the bladder. 11. The implant delivery system of claim 1, further comprising a slit in the atraumatic tip. 12. The implant delivery system of claim 1, wherein the inflation tube has an end configured to couple with the inflatable implant to allow inflation of the inflatable implant while the end is positioned within the central lumen. 13. The implant delivery system of claim 12, wherein the implant decoupler is configured to decouple the inflatable implant from the end of the inflation tube within the central lumen after inflation of the inflatable implant from the un-inflated state to an inflated state. 14. A method of delivering an inflatable implant into a bladder via a urethra comprising: inserting an elongate tubular body of a delivery device within a urethra, the elongate tubular body comprising a central lumen holding an inflatable implant in an initial un-inflated state for delivery of the implant into a bladder;passing a distal tip of the elongate tubular body into the bladder;inflating the implant while it is positioned in the central lumen, inflating the implant causes the implant to expand outward from the central lumen and into the bladder;disengaging the inflatable implant within the bladder from said delivery device; andremoving the delivery device from the bladder. 15. The method of claim 14, wherein inflating the implant while it is positioned in the central lumen further comprises expanding the implant laterally from the central lumen out of a lateral opening of the elongate tubular body. 16. The method of claim 15, wherein expanding further comprises expanding the implant out of the lateral opening in a direction substantially opposite to that of a trigone of the bladder. 17. The method of claim 15, wherein expanding further comprises expanding the implant out of the lateral opening so that the entire implant moves in a direction towards a dome of the bladder. 18. The method of claim 15, wherein expanding further comprises opening a flap covering the lateral opening. 19. The method of claim 15, further comprising removing a covering over the lateral opening. 20. The method of claim 14, wherein inflating the implant further comprises injecting at least one of a liquid and a gas into the implant. 21. The method of claim 20, wherein the liquid injected into the implant comprises at least one of a high vapor pressure medium and a therapeutic agent. 22. The method of claim 20, wherein inflating the implant further comprises injecting gas into the implant after injecting liquid. 23. The method of claim 14, wherein passing the distal tip further comprises passing the distal tip of the elongate tubular body into the bladder until there is at least one of visual and tactile feedback that the distal tip is within the bladder. 24. A method of delivering an inflatable implant into a bladder via a urethra comprising: inserting an elongate tubular body of a delivery device within a urethra, the elongate tubular body comprising a central lumen holding an inflatable implant in an initial un-inflated state for delivery of the implant into a bladder;passing a distal tip of the elongate tubular body into the bladder;inflating the implant and thereby advancing the implant from within the central lumen to outside of the central lumen and into the bladder, wherein inflating the implant comprises injecting a gas into the implant after injecting a liquid;disengaging the inflatable implant within the bladder from said delivery device; andremoving the delivery device from the bladder. 25. The method of claim 24, wherein inflating the implant comprises injecting the gas and the liquid into the implant from a single syringe. 26. An implant delivery system configured to deliver an inflatable implant into a bladder via a urethra, the delivery system comprising: an elongate tubular body sized to pass through a urethra into a bladder, the tubular body extending along a longitudinal axis and comprising: a central lumen configured to hold an inflatable implant in an initial un-inflated state for delivery of the implant into the bladder; anda lateral opening operable to deliver the inflatable implant out of a side of the central lumen substantially perpendicular to the longitudinal axis and into the bladder away from a wall of the bladder;an inflation tube positioned within the central lumen of the tubular body, the inflation tube configured to couple with the inflatable implant to allow inflation of the inflatable implant from within the tubular body; andan implant decoupler positioned within the central lumen of the tubular body around the inflation tube, the implant decoupler configured to decouple the inflatable implant from the inflation tube after inflation of the inflatable implant from the un-inflated state to an inflated state. 27. The implant delivery system of claim 26, wherein the inflation tube has an end configured to couple with the inflatable implant to allow inflation of the inflatable implant while the end is positioned within the central lumen.
