Construction for an implantable medical device having a battery affixed to the case

Designs and methods of construction for an implantable medical device employ an internal support structure. The single-piece support structure holds various electronic components such as a communication coil and a circuit board, and further is affixed to a battery, thus providing a subassembly that is mechanically robust. The support structure further provides electrical isolation between these and other components. A method of construction allows for the subassembly to be adhered to a case of the implantable medical device at the battery, and possibly also at the support structure. The battery includes an insulating cover having holes. An adhesive is used consistent with the location of the holes to affix the battery to the case without electrically shorting the battery to the case.

Stimulation devices and methods for treating dry eye

Described herein are devices and methods of use thereof for treating dry eye, tired eye, or other forms of ocular discomfort such as from contact lenses. The methods generally include applying spatially and/or temporally patterned stimulation to one or more anatomical structures located in an ocular or nasal region. The electrical stimulation may elicit a reflex that activates the lacrimal gland or may directly activate the lacrimal gland or nerves innervating the lacrimal gland to produce tears. The devices may be implantable or handheld, and may be configured to deliver the spatially and/or temporally patterned stimulation patterns described.
