Access devices and related methods of use
A system for accessing a patient's body may include an elongate member having a proximal end, a distal end, and two lumens. The elongate member may include two lumens and a thickness of material extending between external and internal surfaces of the elongate member. The system may also include a first illumination device associated with a first of the two lumens such that a portion of the first illumination device may extend into the thickness of material. A second illumination device may be associated with the second of the two lumens such that a portion of the second illumination device may extend into the thickness of material. Further, the system may include an imaging device having a first portion extending into the thickness of material, a second portion protruding into the first of the two lumens, and a third portion protruding into the second of the two lumens.
1. A system for accessing a location within a body, the system comprising:
an elongate member having a proximal end, a distal end, and two lumens extending therebetween, wherein the elongate member includes an external surface, an internal surface that surrounds the two lumens, and a thickness of material extending between the external and internal surfaces;
a first illumination device associated with a first of the two lumens, wherein a portion of the first illumination device extends into the thickness of material and the remaining portion of the first illumination device protrudes into the first of the two lumens;
a second illumination device associated with the second of the two lumens, wherein a portion of the second illumination device extends into the thickness of material and the remaining portion of the second illumination device protrudes into the second of the two lumens; and
an imaging device having a first portion extending into the thickness of material, a second portion protruding into the first of the two lumens, and a third portion protruding into the second of the two lumens;
wherein the first illumination device is disposed in a first channel, the second illumination device is disposed in a second channel, and the imaging device is disposed in a third channel, wherein each of the first channel, the second channel, and the third channel is separated from the respective lumens by an expandable divider.
2. The system of claim 1 , wherein the imaging and illumination devices are spaced from one another.
3. The system of claim 1 , wherein a portion of the elongate member is steerable.
4. The system of claim 1 , wherein the first and second illumination devices include light sources.
5. The system of claim 1 , wherein the first and second illumination devices include light guide tubes having light sources at proximal ends of the light guide tubes.
6. The system of claim 1 , wherein the imaging and illumination devices are fixedly embedded within the thickness of material.
7. The system for claim 1 , wherein the imaging and illumination devices are slidably received within the thickness of material.
8. The system of claim 1 , wherein the divider is configured to collapse so as to not protrude into the respective lumens when the imaging and illumination devices are removed from the respective channels.
9. The system of claim 1 , further including a surgical tool within the lumen.
10. The system of claim 1 , wherein each of the two lumens are axially fixed with respect the elongate member.
11. A system for accessing a location within a body, the system comprising:
an elongate member having a proximal end, a distal end, and two lumens extending therebetween, wherein the elongate member includes an external surface, an internal surface that surrounds the two lumens, and a thickness of material extending between the external and internal surfaces;
a first illumination device associated with a first of the two lumens, wherein at least a portion of the first illumination device extends into the thickness of material;
a second illumination device associated with the second of the two lumens, wherein at least a portion of the second illumination device extends into the thickness of material; and
an imaging device having a first portion extending into the thickness of material;
wherein a portion of the elongated member is steerable; and
wherein the first illumination device is disposed in a first channel, the second illumination device is disposed in a second channel, and the imaging device is disposed in a third channel, wherein each of the first channel, the second channel, and the third channel is separated from the respective lumens by an expandable divider.
12. The system of claim 11 , wherein the first and second illumination devices include light sources.
13. The system of claim 11 , wherein the first and second illumination devices include light guide tubes having light sources at proximal ends of the light guide tubes.
14. The system of claim 11 , wherein the imaging and illumination devices are fixedly embedded within the thickness of material.
15. The system for claim 11 , wherein the imaging and illumination devices are slidably received within the thickness of material.
16. The system of claim 11 , wherein the divider is configured to collapse so as to not protrude into the respective lumens when the imaging and illumination devices are removed from the respective channels.
17. The system of claim 11 , wherein each of the two lumens are axially fixed with respect the elongate member.
