  • Patent number: 10357656
    Abstract: Presented herein are objective techniques for determining the upper limit of the dynamic range (i.e., the comfort level) of implanted stimulating contacts through the use of electrocochleography (ECoG) measurements to indirectly detect the onset and duration of a recipient's stapedius reflex. In particular, stimulation is delivered to a recipient's cochlea to trigger the onset of the stapedius reflex and the resulting acoustic impedance change is detected by monitoring the acoustically evoked ECoG.

  • Patent number: 10328261
    Abstract: Embodiments described herein generally relate to devices and methods for stimulation or recording of accommodation of an eye. Accommodation of an eye naturally occurs through contraction of the ciliary muscle. Embodiments described herein can deliver electrostimulation to the ciliary muscle through a pair of electrodes which deliver power over an area of the sclera which is both positioned above and over an area which is substantially equivalent to the surface area of the ciliary muscle. In further embodiments, electrical impulses produced by the ciliary muscle can be received by one or more electrodes positioned proximate the ciliary muscle. Thus, by embodiments described herein, accommodation of the eye can be reproducibly achieved by external stimulation of the ciliary muscle or measured based on electrical impulses generated by or in conjunction with the ciliary muscle.

  • Patent number: 10328273
    Abstract: Medical devices include a separate enclosure that houses a battery and electrically isolates the battery from external conditions such as any metal enclosures and ultimately isolates the battery from body fluids. Thus, the separate enclosure attaches to a housing of a medical device and provides for modularity of the battery which allows, for instance, different size batteries to be used with the same medical device design. The separate enclosure further prevents stimulation current from leaking back to the battery housing by providing the electrical isolation.

  • Patent number: 10328257
    Abstract: An implantable medical device assembly includes a mounting structure, an electrode, and fixation tines. The electrode protrudes from a surface of the structure, offset proximally from a distal end of the structure, and approximately centered between first and second sides of the structure. Each tine extends away from the surface—a first adjacent the first side, and a second adjacent the second side. Each tine is elastically deformable from a relaxed condition, in which the tine extends toward a proximal end of the structure, to an extended condition, in which the tine extends away from the distal end of the structure. A delivery tool has first and second longitudinally extending sidewalls to receive passage of the structure therebetween. When the structure distal end is located between proximal ends of the sidewalls, a rail-like edge of each sidewall receives, and elastically deforms to the extended condition, a corresponding tine.

  • Patent number: 10321838
    Abstract: An active low impedance electrode (20) employing an electrical activity sensor (21) connected to a voltage sense contact (22), a current flow contact (23) and an active electrode coupler (24). In operation, responsive to the voltage sense contact (22) and the current flow contact (23) being attached to the anatomical region (13) of the patient, the electrical activity sensor (21) controls a directional flow of a sensor current between the electrical activity sensor (21) and the anatomical region (13) to establish an equivalence between a patient voltage at voltage sense contact (22) and a sensor voltage at active electrode coupler (24), and/or a patient contact impedance between the voltage sense contact (22) and the current flow contact (23) is greater than an active electrode impedance at the active electrode coupler (24).

  • Patent number: 10315026
    Abstract: A system and method for stimulating a user, the system comprising: a set of pads configured at head regions of the user; a band having a first end coupled to a first pad of the set of pads and a second end coupled to a second pad of the set of pads; a bridge coupled the band and to an electrode during use; and a set of links, each link coupled at a first region to an interior portion of its corresponding pad, and coupled at a second region to the bridge, having an elastic modulus above a threshold modulus such that: in a first mode, displacement of the set of pads produces displacement of the electrode away from the head region of the user, and in a second mode, release of the set of pads orients protrusions of the electrode approximately normal to the head region.

  • Patent number: 10307605
    Abstract: A gel deployment device for use with an electrotherapy system is provided. The device includes a plurality of gel reservoirs disposed on a substrate, each of the plurality of gel reservoirs containing conductive gel. Each of the gel reservoirs are positioned adjacent to at least one seal such that the seal restricts flow of the conductive gel. The seal can be configured to release the conductive gel from the gel reservoir in response to pressure being applied about a perimeter of the seal at, for example, multiple points about the perimeter or substantially equally about the perimeter of the seal. In an example, each gel reservoir can be shaped such that the gel reservoir partially or fully surrounds a seal. In another example, multiple gel reservoirs can be arranged in clusters such that the multiple gel reservoirs are positioned about a single seal.

  • Patent number: 10293156
    Abstract: Medical lead bodies that are paired each include a braided conductive shield. The braided conductive shield of one lead body has a value for a physical parameter that differs from a value for the physical parameter of the second lead body. The difference in values of the physical parameter for the paired lead bodies results in a reduction in heating from exposure of the lead bodies to radiofrequency energy at electrodes associated with the lead bodies. The lead bodies may be paired by being implanted adjacently to one another. The lead bodies may be further paired by being coupled to a same distal body, such as a paddle containing the electrodes.

  • Patent number: 10286214
    Abstract: An intracardiac ventricular pacemaker having a motion sensor is configured to produce a motion signal including an atrial systolic event and at least one ventricular diastolic event. The pacemaker is configured to set an atrial refractory period, detect a change in a ventricular diastolic event metric and adjust the atrial refractory period in response to detecting the change. The pacemaker sets set an atrioventricular pacing interval in response to detecting the atrial systolic event from the motion signal after expiration of the atrial refractory period.

  • Patent number: 10279092
    Abstract: A mounting ring for a ventricular assist device or other device used in the heart includes a plate adapted to be secured to the exterior of the heart by rigid anchors such as hook, pin, or screw. When hooks are used, they can be pivotally mounted to the plate so that the hooks can rotate from retracted positions to advanced positions. A tool can be included in a mounting ring kit to move the hooks from their retracted positions to their advanced positions so that the hooks secure the plate to the heart. Preferably, all of the hooks are advanced simultaneously. The VAD or other device is then secured to the plate. The plate can be mounted to the heart in less time than required to install a traditional mounting ring by suturing to the heart.
