Abstract: The present specification discloses methods of assessing the extent of capsular contracture around an implantable device and methods of monitoring fibrous capsular formation relating to an implantable device.

Abstract: Devices and methods for positioning an implant at a target location in the body. The methods include testing an implant while within an injection device at a target location to determine whether the implant is functioning effectively. The methods also include testing from or delivery of materials to the target location during implantation, and loading the injection device for use. The device may be configured to permit the longitudinal and/or axial position of the implant to be maintained relative to an injection device during implantation. The device may also be configured to permit testing of the implant. Implants configured for use in the injection devices may also be included.

Abstract: The subject invention teaches the use of electrical stimulation of specific sensory nerves, such as the proximal urethral afferents to control urination. A wireless, injectable microstimulator may implanted into the soft tissues through which the sensory nerves pass. The sensory nerves supplying the proximal urethra are stimulated by a microstimulator implanted adjacent to the prostatic urethra within the substance of the prostate gland in males, and distal to the bladder neck in females. The activity induced in these nerves causes the spinal cord to generate reflex responses that result in contractions of the detrusor muscle and relaxation of the sphincter, emptying the bladder. The invention also includes methods of implanting and/or testing microstimulators at a target location. The invention also includes the use of sensory devices to effect the microstimulators or alert the user as to the status of the bladder.
