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.

First claim

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

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.

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

3. The medical device of claim 2 , wherein each of the one or more LEDs produces light of the same wavelength.

4. The medical device of claim 2 , wherein the one or more LEDs comprises at least two LEDs, and one of the LEDs produces light of a different wavelength than at least one other LED of the at least two LEDs.

5. 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.

6. The medical device of claim 1 , further comprising:
at least one of an image sensor and an imaging light guide configured to capture images of the body cavity.

7. The medical device of claim 1 , wherein the elongate body defines a lumen extending through each of the one or more LEDs.

8. The medical device of claim 1 , further comprising:
a second electrode positioned distally to the first electrode, wherein the one or more LEDs extends between the first electrode and the second electrode.

9. The medical device of claim 1 , wherein the one of more LEDs comprises only one LED, and the only one LED completely encircles a length of the outer surface of the elongate member.

10. 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, wherein each of the one or more LEDs extends distally of an electrode on the elongate member; and
a heat conductive polymer that is thermally coupled to the one or more LEDs to dissipate heat from the one or more LEDs;
wherein the elongate member defines one or more lumens extending through each of the one or more LEDs.

11. The medical device of claim 10 , wherein the one or more LEDs encircle a length of the outer surface of the elongate member.

12. The medical device of claim 10 , wherein the one or more LEDs are organic LEDs.

13. The medical device of claim 10 , further comprising:
at least one of an image sensor and an imaging light guide configured to capture images of the body cavity.

14. The medical device of claim 10 , wherein each of the one or more LEDs is organic and produces light of the same wavelength.

15. The medical device of claim 10 , wherein the one or more LEDs comprises at least two LEDs, and is organic and produces light of a different wavelength than at least one other LED of the at least two LEDs.

16. 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, wherein each of the one or more LEDs extends distally of an electrode on the elongate member;
at least one of an image sensor and an imaging light guide configured to capture images of the body cavity; and
a heat conductive polymer that is thermally coupled to the one or more LEDs to dissipate heat generated by the one or more LEDs.

17. The medical device of claim 16 , wherein the one or more LEDs are strip-shaped organic LEDs extending along an exterior surface of the elongate member.

18. The medical device of claim 17 , wherein the one or more strip-shaped organic LEDs include a plurality of indicia spaced at predetermined distances.

19. The medical device of claim 16 , wherein each of the one or more LEDs encircles a length of an outer surface of the elongate member.

20. The medical device of claim 16 , wherein the elongate body defines a lumen extending through the one or more LEDs.
