Abstract

A medical device such as a catheter or endoscope device includes an illumination light source having one or more organic light-emitting diodes (OLEDs). The OLEDs are energized to produce illumination light that is received by an image sensor or camera to produce images of tissue within a patient'"'"'s body. A heat conductive polymer conducts heat away from the illumination light source.

Claims

1. A medical device for illuminating a body cavity of a patient, comprising:

an elongate member having a proximal end that remains outside the body cavity and a distal end that is insertable into the body cavity;

one or more LEDs that illuminate the body cavity; and

a heat conductive polymer that is thermally coupled to the one or more LEDs to dissipate heat from the one or more LEDs.

2. The medical device of claim 1, wherein the elongate member is at least partially formed of the heat conductive polymer.

3. The medical device of claim 1, wherein the elongate member includes a length of the heat conductive polymer in thermal contact with the one or more LEDs.

4. The medical device of claim 1, wherein the one or more LEDs are organic LEDs.

5. The medical device of claim 4, wherein the one or more organic LEDs produce light of the same wavelengths.

6. The medical device of claim 4, wherein the one or more organic LEDs produce light of different wavelengths.

7. The medical device of claim 1, wherein the one or more LEDs are disposed at or adjacent to the distal end of the elongate member.
