Systems and methods for implementation of a disposable miniaturized implant for treatment of Post-Operative Ileums (POI),a miniaturized implant for treating chronic GI dysmotility (e.g., dysphagia, gastroesophageal reflux disease (GERD), nausea, functional dyspepsia, blockage of transit, and gastroparesis, inflammatory bowel disease) and obesity, by providing electrical stimulation to the part of bowel going through surgery to expedite the healing process while recording the smooth muscle activities simultaneously, or providing stimulation on a treatment location of the GI tract or the branch of the vagus nerve. Systems and methods are also provided for non-invasive, transcutaneous stimulation of anatomy within the abdomen of the patient.

Methods, systems, and devices for wireless signal transmission are described. A fractal antenna may be utilized to wirelessly communicate with a transmitter implanted within or located external to the patient. The fractal antenna may be implanted within the patient and may be coupled with a lead also implanted within the patient. The characteristics of the fractal antenna may allow for enhanced data transmission between the antenna and the transmitter while reducing the need for implanted wires to connect the transmitter and leads.

A device for securing an external transmitter of a cochlear implant to the head of the wearer. A pouch containing the external transmitter is secured using a plurality of straps coupled to a decorative shell worn on a person's head. The pouch and the decorative shell are designed to allow sound to pass unhindered from the environment to the inner ear. The plurality of straps are adjustable to allow precise placement of the external transmitter over the internal receiver. The external transmitter is also secured using a pouch coupled to a decorative shell. The external transmitter is further secured using a sealer coupled to the transmitter and further coupled to the head using an adhesive barrier. The sealer is made of a semi-transparent material. The device ensures that an external transmitter remains in place.

Generally discussed herein are systems, devices, and methods for providing a therapy (e.g., stimulation) and/or data signal using an implantable device. Systems, devices and methods for interacting with (e.g., communicating with, receiving power from) an external device are also provided.

A method for enhancing muscle function of skeletal muscles in connection with a planned spine surgery intervention in a patient's back is provided. The method includes implanting one or more electrodes in or adjacent to tissue associated with one or more skeletal muscles within a back of a patient, the one or more electrodes in electrical communication with a pulse generator programmed for enhancing muscle function of the one or more skeletal muscles. Electrical stimulation is delivered, according to the programming during a time period associated with the planned spine surgery intervention, from the pulse generator to the tissue associated with the one or more skeletal muscles via the one or more electrodes, thereby improving neuromuscular control system performance of the one or more spine stabilizing muscles in connection with the planned spine surgery intervention to reduce the patient's recovery time associated with the planned spine surgery intervention.

An antenna for electrical coupling to a wireless communication circuit includes a first conductive strip segment having a first length, a second conductive strip segment having a second length different from the first length and coupled to the first conductive strip segment at a feed point to be electrically coupled to the drive node, and a third conductive strip segment having a third length less than both the first length and the second length. A first end of the third conductive strip is coupled to the feed point and a second end is coupled to circuit ground. The first conductive strip segment provides a first specified operating frequency range at a fundamental resonance mode corresponding to the first length plus the third length, and the second conductive strip segment provides a second specified operating frequency range at a fundamental resonance mode corresponding to the second length plus the third length.

An improved stimulus coil for use in wireless stimulation of biological tissue (e.g., nerves, muscle tissue, etc.) and, in one exemplary implementation, to glaucoma therapy based on the wireless administration of energy to the eye of a mammalian subject (e.g., human, rodent, etc.) to reduce an elevated intraocular pressure (IOP) involving the use of an improved stimulus coil. The improved stimulus coil may be implanted in the eye of a mammalian subject or positioned on the exterior of the eye, such as (by way of example) by being disposed within a contact lens worn by a mammalian subject.

An implantable stimulator includes a housing, a plurality of electrodes positioned along the housing, and a printed circuit board positioned along the housing. The printed circuit board includes control circuit components, a plurality of electrode connector pads, an antenna, and a receiver relay positioned along the printed circuit board such that a portion of the receiver relay overlaps with the antenna.

The disclosure describes examples of antennas used for communication with an implantable medical device (IMD). As one example, the IMD includes a housing configured to house communication circuitry within an internal side of the housing, and a planar antenna, having a curved structure, that is stacked on an external side of the housing and coupled to the communication circuitry. As another example, the IMD includes a housing configured to house communication circuitry within an internal side of the housing and an antenna having a curved structure formed on an external side of the housing and coupled to the communication circuitry. A resonant frequency of the antenna is based on a dielectric constant of tissue surrounding the antenna when the IMD is implanted, and a current distribution of the antenna is in-phase in opposite sides of the antenna.

The implant comprises a tubular body housing an energy harvesting module adapted to convert external stresses applied to the implant into electrical energy, and a rechargeable battery adapted to be charged by the energy harvesting module. During the storage, an external source physically separated from the implant is coupled to the implant rechargeable battery to maintain a minimum battery charge level. An interface circuit of the implant couples surface electrodes to the battery, with switching between: i) a transport and storage configuration where the electrodes are connected to the external source to receive from the latter a battery charging energy and/or to exchange communication signals with the outside through the wire link of the coupling; and ii) a functional configuration in which the surface electrodes are decoupled from the external source after the implant has been implanted. At least one of the implant surface electrodes is an auxiliary electrode that is not a cardiac potential detection/pacing electrode. In the transport and storage configuration, the interface circuit couple the auxiliary electrode to the implant rechargeable battery, and in the functional configuration, the interface circuit decouples the auxiliary electrode from the implant rechargeable battery and put the auxiliary electrode to a floating potential.
