Abstract

A powered portable laser bandage having one or many vertical cavity surface-emitting laser arrays embedded therein may be worn by a patient and applied to an area of the patient'"'"'s body near the heart. The device supplies the patient with a preprogrammed laser therapy regimen. A physician programs the device and attaches the device to a patient who may then wear the device for several days without visiting a physician. The device is small enough to be worn under clothes and does not interfere with the patient'"'"'s normal activities. The low-level laser energy promotes angiogenesis of the heart myocardium. Alternatively, the device may be adapted to be implanted into a skin surface of the patient, or provided in a catheter that is inserted in the vasculature system of the patient.

Claims

1. An apparatus for performing laser biostimulation therapy comprising:

means for emitting at least one beam of laser energy; and

a catheter comprising

a housing having a main lumen defined within an inner edge of said housing,

an inflatable balloon surrounding said housing and communicating with said main lumen,

means for inflating said balloon coupled to said main lumen,

a flexible sleeve surrounding said balloon, and

at least one electrically conductive strip embedded within said flexible sleeve, said emitting means disposed on a surface of said at least one electrically conductive strip.

2. The apparatus of claim 1, wherein said emitting means further comprises at least one VCSEL operatively connected with said controlling means for generating said at least one beam of laser energy.

3. The apparatus of claim 1, further comprising means for storing a treatment regimen for the apparatus, said storing means being operatively connected to said controlling means.

4. The apparatus of claim 1, wherein said controlling means is programmable.

5. The apparatus of claim 1, wherein said flexible sleeve is comprised of an optically transparent material.

6. The apparatus of claim 1, wherein said optically transparent material is comprised of soft silicone.

7. The apparatus of claim 1, wherein said flexbile sleeve has a thickness in a range of approximately 0.25 to 0.50 millimeters.
