Device and method for enhanced visualization of the small intestine
A device for distending a body lumen for enhanced visualization with a capsule endoscope that includes a camera lens includes an attachment element configured to attach to the capsule endoscope and a plurality of struts extending from the attachment element and meeting at an apex. The plurality of struts are configured to extend both axially and radially away from the camera lens so as to form a frame therearound.
1. A device for visualization of a body lumen, comprising:
a capsule endoscope comprising a camera lens;
a plurality of struts extending from the capsule endoscope radially outwardly from a longitudinal axis of the capsule endoscope and axially along the longitudinal axis of the capsule endoscope and connecting at an apex and configured to maintain a field of view around the camera lens while the device is providing visualization of the body lumen, wherein the plurality of struts extend away from the camera lens so as to form a frame therearound.
2. The device of claim 1 , wherein the plurality of struts is configured to distend tissue as the capsule endoscope travels through the body lumen.
3. The device of claim 1 , further comprising an attachment element configured to attach to the capsule endoscope, wherein the plurality of struts extend from the attachment element.
4. The device of claim 1 , wherein there are between 4 and 6 struts in the plurality of struts.
5. The device of claim 1 , wherein each of the plurality of struts is self-expandable.
6. The device of claim 5 , wherein each of the plurality of struts is formed of a shape memory material.
7. The device of claim 1 , wherein the frame includes a biodegradable portion.
8. The device of claim 1 , wherein the frame includes a tapered tip.
9. The device of claim 8 , wherein an angle of the taper is between 30° and 60° .
10. A device for visualization of a body lumen, comprising:
a capsule endoscope comprising a camera lens;
a plurality of struts extending from the capsule endoscope and connecting at an apex and configured to maintain a field of view around the camera lens while the device is providing visualization of the body lumen, the plurality of struts forming a frame around the capsule endoscope and configured to distend tissue as the capsule endoscope travels through the body lumen.
11. The device of claim 10 , further comprising an attachment element configured to attach to the capsule endoscope, wherein the plurality of struts extend from the attachment element.
12. The device of claim 10 , wherein there are between 4 and 6 struts in the plurality of struts.
13. The device of claim 10 , wherein each of the plurality of struts is self-expandable.
14. The device of claim 13 , wherein each of the plurality of struts is formed of a shape memory material.
15. The device of claim 10 , wherein the frame includes a biodegradable portion.
