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;
a substrate having a first electrode formed thereon;
one or more LEDs that illuminate the body cavity, each of the one or more LEDs radially surrounding a length of an outer surface of the elongate member and extending distally of the substrate and first electrode; and
a heat conductive polymer that is thermally coupled to the one or more LEDs to dissipate heat from the one or more LEDs.

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.
