Friction-based therapeutic light penile device

A friction-based therapeutic light penile device comprising:

• a) a sleeve comprising:
• i) an outer shell;
• ii) a friction sleeve configured within the outer shell and forming a hollow channel along an inside surface of the friction sleeve with an insertion opening configured for insertion of a penis;
• iii) a length of the hollow channel from said insertion opening to an extended end;
• and
• iv) a plurality of light devices configured to emit an emitted light into the hollow channel;
• wherein the plurality of light devices are attached to the outer shell at an offset distance from the hollow channel to produce emitted light producing substantially full coverage over at least 80% of said inside surface along said length of the friction sleeve;
• and
• wherein the plurality of light devices are configured to produce overlapping emitted light on the inside surface of the sleeve, wherein a first light device of the plurality of light devices emits a first emitted light that overlaps with a second emitted light from a second light device of the plurality of light devices;
• b) a power source to power the light devices;
• wherein the friction sleeve is translucent to allow light to pass through the friction sleeve and into the hollow channel;
• wherein the friction sleeve comprises an elastomeric material that is configured to be deformed by said penis and return to an original shape after being deformed;
• wherein the plurality of light devices are configured circumferentially around the sleeve, wherein the first light device is configured a circumferential offset angle from the second light device.
