The inventors note that the device described herein includes several features intended to provide a positive user experience.

With respect to structure, a therapeutic tip may include a screw thread to hold a case together with no external screws. According to an embodiment, a device includes a metal or metal-coated plastic return electrode on a case structure portion that occupies an area selected to make it nearly impossible for a user to hold the device without completing a circuit. In an embodiment, the device uses metal-plated plastic. In an embodiment, the device uses punched aluminum for an exposed portion of the return electrode.

Referring to FIGS. 1-3, according to an embodiment, a microcurrent sinus treatment device 100, 200 includes a circuit 202 configured to deliver a sequence of voltage pulses carrying a therapeutic current, and a therapeutic electrode 104 operatively coupled to the circuit 202. In an embodiment, the therapeutic electrode 104 may be configured to apply the sequence of voltage pulses to a user's skin surface adjacent to a region of relatively low electrical impedance through the user's skin and to a return electrode on a surface of the microcurrent sinus treatment device 100, 200. According to embodiments, the region of relatively low electrical impedance corresponds to one of a plurality of nerve nodes subjacent to the user's skin surface. In an embodiment, the therapeutic electrode 104 may be in electrical continuity with a therapeutic current output node of the circuit 202. According to an embodiment, the microcurrent sinus treatment device 100, 200 includes a hand holdable case 106 configured to substantially contain active portions of the circuit 202. In an embodiment, the hand holdable case 106 includes a forward end 108 terminating in the therapeutic electrode 104, and a return electrode 110 comprising a portion of or disposed on a surface of the hand holdable case 106. In an embodiment, the return electrode 110 may be in electrical continuity with a current return node of the circuit 202. In an embodiment, the hand holdable case 106 includes a dielectric spacer 112 disposed between the therapeutic electrode 104 and the return electrode 110, and a rearward portion 114 of the hand holdable case 106 terminating at an end 120 a distance selected to comfortably fit in an adult human hand, typically less than about four inches from the therapeutic electrode 104 tip. In an embodiment, the dielectric spacer 112 and the return electrode 110 form a tapered surface 116 narrowing toward the therapeutic electrode 104 from a point of maximum girth 118 disposed between the forward end 108 and the rearward end 120 of the hand holdable case 106.

According to an embodiment, the therapeutic electrode 104 is configured to clamp the return electrode 110 against the rearward portion 114 of the hand holdable case 106 to hold the dielectric spacer 112 and the return electrode 110 together with the rearward portion 114 of the hand holdable case 106. In an embodiment, the therapeutic electrode 104 includes a threaded portion 222 configured to screw into a hole (not shown) formed inside the rearward portion 114 of the hand holdable case 106. In an embodiment, the placement of the therapeutic electrode 104, the dielectric spacer 112, and the return electrode 110 are configured to cause the user's body to complete a circuit between the therapeutic electrode 104 and the return electrode 110.

In an embodiment, the tapered case is adaptable to a large range of hand sizes. In an embodiment, the rearward end 120 of the hand holdable case 106 is less than three inches from the therapeutic electrode 104 tip. In an embodiment, the tapered surface 116 is conducive to cause the user's hand to naturally contact the return electrode 110. In an embodiment, the tapered surface 116 is conducive to provide satisfactory control for holding the therapeutic electrode 104 against the user's skin superjacent to each of the plurality of nerve nodes.

According to an embodiment, in FIGS. 1-3, the hand holdable case 106 forms a surface having an indentation 302 larger than an average user's thumb on a back side 304 of the hand holdable case 106 such that a front portion 306 of the indentation 302 extends toward the therapeutic electrode 104 and away from the point of maximum girth 118 of the hand holdable case 106. In one embodiment, the indentation 302 is disposed with at least a majority of its area between the therapeutic electrode 104 and the point of maximum girth 118. In another embodiment, the indentation 302 is disposed partially extending beyond the point of maximum girth 118 toward the rearward end 120 of the hand holdable case 106.

According to an embodiment, the dielectric spacer 112 defines a concave insulated surface near the therapeutic electrode 104 to make clearance for the user's cheek and/or nose.

According to an embodiment, the hand holdable case 106 defines a tapered surface 122 on a top 124, between the point of maximum girth 118 and the forward end 108, configured to provide a finger hold. In an embodiment, the tapered surface 122 forms a facet relative to other portions of the top 124. According to an embodiment, the hand holdable case 106 defines a convex curved surface 126, on the top 124 between the point of maximum girth 118 and the rearward end 120, configured to fit into a hollow of the user's palm.

According to a embodiment, the hand holdable case 106 defines a tapered side 116 to accommodate finger placement. According to an embodiment, the hand holdable case 106 further includes a light pipe 128 disposed between the forward end 108 and the return electrode 110, the light pipe 128 being configured to output an illumination indicator from a light emitting diode (LED) 230 disposed on the circuit 202 to indicate an operating condition to the user. According to an embodiment, the microcurrent sinus treatment device 100, 200 further includes a button 130 configured to cause the circuit 202 to enter a low current, nerve node finding mode, the circuit 202 being further configured to enter a high current therapeutic voltage pulse mode when a nerve node is found and to automatically shut off when a dose of therapeutic voltage pulses have been delivered. According to an embodiment, the therapeutic electrode 104 may be configured to maximize comfort for the user. This may be accomplished by keeping a diameter and radius of the therapeutic electrode 104 tip at the forward end 108 of the hand holdable case 106 large enough to avoid applying undue pressure against the user's skin. The inventors have found that maximizing the diameter and radius for comfort should be balanced against localization of current flow across the user's skin. In an embodiment, an exposed portion of the therapeutic electrode 104 may have a diameter greater than or equal to 1/16 of an inch (0.0625″) ( 1/32″=0.031″ radius) and less than ¼″ (0.25″) diameter (⅛″ =0.125″ radius). In another embodiment, the exposed portion of the therapeutic electrode 104 may have a diameter greater than or equal to 3/32″ (=0.094″) ( 3/64″=0.047″) and less than or equal to 3/16″ (0.188″) diameter and 3/32″ =0.094″ radius. In another embodiment, the exposed portion of the therapeutic electrode 104 may have a diameter equal to about 5/32″ (0.16″) and 5/64″ (0.078″ radius). Relevant dimensions, according to an embodiment, are shown in FIG. 5.

According to embodiments, the inventors have noted three primary ways users hold the device:

1. Thumb directed—the user puts his/her thumb in the indentation 302 and points toward the user's face. The user's fingers wrap around the hand holdable case 106.

2. Finger directed—the user places his/her index finger on the tapered surface 116 and points toward the user's face. The user's fingers and thumb wrap around the hand holdable case 106.

3. Hybrid—the user places his/her thumb on the indentation 302 and places his/her index finger on the side, both thumb and index finger point toward the user's face. The user's middle finger stabilizes along the front. (Some users were found to be unable to use this technique.)

All three approaches are amenable to right-handed or left-handed use. Users naturally fell into one of the three grips. Features on the hand holdable case 106 enable one or more of the grips.
