1. An implantable device for implantation into tissue adjacent to an urethra connected to a bladder, comprising: an expandable balloon capable of expansion in the tissue adjacent to the urethra connected to an elongate conduit, the elongate conduit configured to provide for a plurality of lumens including a first inner lumen for fluid communication between a first end of the elongate conduit at a proximal portion of the implantable device and the expandable balloon at a second end at a distal portion of the implantable device and a second inner lumen; and a plurality of distal hooks positioned at a distal tip of the elongate conduit to be deployed distally to the expandable balloon, wherein the implantable device is configured for implantation within the tissue with the expandable balloon adjacent the urethra for adjustable coaptation to the urethra, wherein the plurality of distal deployable hooks is configured to be deployed into the tissue adjacent the urethra after positioning the implantable device to provide fixation of the implantable device in the tissue adjacent the urethra, wherein the expandable balloon and the plurality of distal hooks are arranged for the expandable balloon to shield the bladder from being punctured by the plurality of distal hooks positioned at the distal tip of the elongate conduit when the expandable balloon is expanded, and wherein a stiffener comprising an aperture for filling the expandable balloon is disposed onto an expandable balloon portion of the elongate conduit.
