A urinary pumping device (1) for generating a fluid flow through an urethra (22; 220) of a patient (2; 20), comprises an implantable activation arrangement (11) and a control unit (12). The implantable activation arrangement (11) is configured to induce intermittent compression and release of the urethra (22) when being implanted into the patient (2). The control unit (12) is coupled to the activation arrangement (11). The control unit (12) is configured to operate the activation arrangement (11) such that the fluid flow through the urethra (22) is generated by the activation arrangement (11) inducing intermittent compression and release of the urethra (22).

Systems, devices, methods, and techniques are described for phase misalignment correction for evoked compound action potential (ECAP) measurement from alternating polarity stimulation. An example system includes processing circuitry that receives a first ECAP signal elicited by a first polarity configuration of stimulus electrodes and receives a second ECAP signal elicited by a second polarity configuration of the stimulus electrodes opposite the first polarity configuration. The processing circuitry also generates an adjusted second ECAP signal by temporally aligning at least a portion of the second ECAP signal to at least a portion of the first ECAP signal, and generates a composite ECAP signal based on the first ECAP signal and the adjusted second ECAP signal. Additionally, the processing circuitry outputs the composite ECAP signal.

In some examples, a technique for delivering electrical stimulation therapy to a patient includes determining, by processing circuitry, one or more cycle settings associated with delivery of the electrical stimulation therapy, determining, by the processing circuitry, a cycle time period associated with each cycle setting, and delivering, by a medical device, electrical stimulation therapy based on the determined cycle settings and the determined cycle time periods. Each cycle setting may define an on-cycle, during which electrical stimulation is delivered, and an off-cycle, during which electrical stimulation is not delivered. The technique further may include delivering electrical stimulation to the patient to provide one or more reminders to the patient, such as a reminder to void or a reminder of the existence of electrical stimulation.

An apparatus for the treatment of urinary incontinence includes a probe, processing electronics, and a display. The probe includes a balloon, an electrode, and an internal cavity defined by the balloon. An electrode is coupled to an outer surface of the balloon, and is configured to transmit an electrical pulse to cause a contraction of a muscle in communication with the electrode. The internal cavity does not include a structural support element. The processing electronics are in communication with the electrode and configured to receive a signal indicative of a force of the contraction of the muscle and determine a value of the force of the contraction based on the signal. The display is in communication with the processing electronics and configured to receive the value of the force of the contraction from the processing electronics and present the value of the force of the contraction on the display.

An apparatus for the treatment of urinary incontinence includes a balloon configured for movement between an inflated state and a deflated state, and the balloon includes bellows. An electrode is coupled to an outer surface of the balloon, and is configured to transmit an electrical pulse to cause a contraction of a muscle in communication with the electrode. A control device is configured to be operable by a user to cause the balloon to selectively move between the inflated state and the deflated state and to cause the electrode to transmit the electrical pulse. The bellows and the electrode are configured to cooperate to maintain the structural integrity of the balloon. The bellows and the electrode are further configured to cooperate to cause the balloon to inflate in a radially non-uniform manner.

A stimulator device for controlling waste storage for a subject, having one electrode placed in proximity to a portion of each of the right and left pudendal nerves, which contains efferent fibers that, when stimulated, produce contraction of the urethral or anal sphincter. The stimulator device having a pulse generator connected to electrodes, bilaterally, to provide stimulation for each electrode to stimulate pudendal efferent axons. The pulse generator adapted to provide a first type of stimulation to cause waste to be stored within the subject. The pulse generator adapted to provide a second type of stimulation, different from the first type of stimulation, to allow waste to be voided from the subject by blocking nerve impulses that accompany sphincter dyssynergia. An input device to allow an end user to select the first type of stimulation, the second type of stimulation, or no stimulation. Variations of the concept are disclosed.

An external intra-pelvic fundus vesicae support disposed at the outer fundus vesicae position and fixing the front end to the pelvic pecten pubis position to lift internal organs. An injection channel is provided inside an external intra-pelvic fundus vesicae support structure, and a screw hole is formed at an input hole, so that the support can be connected to an in-vitro device. According to the external intra-pelvic fundus vesicae support, a tomoscan three-dimensional modeling technology is used to generate a model file which completely conforms to physiological shapes of the pelvic pecten pubis and the outer fundus vesicae and the spatial form of the abdominal cavity of a typical person, and the external intra-pelvic fundus vesicae support of a frame structure and medical material quality is obtained using 3-D printing technologies. Before a surgery is conducted, a virtual reality technology is used to simulate and verify a surgical safety scheme.

An implant unit configured for implantation into a body of a subject is provided. The implant unit may include a flexible carrier unit including a central portion and two elongated arms extending from the central portion, an antenna, located on the central portion, configured to receive a signal, at least one pair of electrodes arranged on a first elongated arm of the two elongated arms. The at least one pair of electrodes may be adapted to modulate a first nerve. The elongated arms of the flexible carrier may be configured to form an open ended curvature around a muscle with the nerve to be stimulated within an arc of the curvature.

A device for the treatment of snoring is provided. The device may include a flexible substrate configured for removable attachment to a subject's skin, a primary antenna disposed on the flexible substrate, an interface configured to receive a feedback signal that varies based upon a breathing pattern of the subject; and at least one processing device. The processing device may be configured to analyze the feedback signal and determine whether the subject is snoring based on the analysis of the feedback signal, and if snoring is detected, cause a hypoglossal nerve modulation control signal to be applied to the primary antenna in order to wirelessly transmit the hypoglossal nerve modulation control signal to a secondary antenna associated with an implant unit configured for location in a body of the subject.
