Abstract

A medical device introduction system is adapted to be at least partially insertable into an interior body region of a patient. The system includes a medical imager including a body member having a handle, an elongate member extending from the handle, an imaging device carried at a distal portion of the elongate member, and an introducer enclosing the elongate member. A manipulator is configured for imparting displacement of the introducer to form an angled end portion to define a line of sight extending from the angled end portion. The manipulator is further configured for altering the line of sight to increase a viewing angle of the imaging device.

Claims

1-21. -21. (canceled)

22. A medical apparatus, comprising:

an disposable elongate sheath having a proximal end and a distal end and including at least four lumens, the at least four lumens including a working channel, a viewing channel, a fluid inflow channel, and a fluid outflow channel;

the working channel extending between an opening at the proximal end of the elongate sheath and an opening at the distal end of the elongate sheath, the working channel being configured to receive a surgical tool therethrough from the proximal end of the elongate sheath and to extend from the distal end of the elongate sheath;

the viewing channel extending between the proximal and distal ends of the elongate sheath; and

the fluid inflow and fluid outflow channels each defining a fluid passage therethrough and each extending proximally from the distal end of the elongate sheath to a point at least partway along the elongate sheath, the fluid inflow channel being configured to provide inflows of fluid for disposition in the body cavity, the fluid outflow channel being configured to receive outflows of fluid from the body cavity.

23. The medical apparatus of claim 22, further comprising an engagement hub on the proximal end of the elongate sheath, the engagement hub being configured to removably engage an imaging device.

24. The medical apparatus of claim 23, wherein the engagement hub is configured to prevent relative movement between the introducer and the imaging device.

25. The medical apparatus of claim 23, wherein the engagement hub has a plurality of engagement features extending proximally therefrom that are configured to mate with corresponding features on the imaging device.

26. The medical apparatus of claim 22, wherein the viewing channel terminates at the distal end of the elongate sheath in a transparent member.

27. The medical apparatus of claim 22, wherein the viewing channel is configured to receive an imaging device therein.

28. The medical apparatus of claim 27, wherein the imaging device includes a Complementary Metal-Oxide Semiconductor (CMOS) sensor.

29. The medical apparatus of claim 22, wherein the elongate sheath has an angled distal region that is angled at a non-zero angle relative to the longitudinal axis of the elongate sheath.

30. The medical apparatus of claim 22, wherein the fluid inflow and fluid outflow channels are each configured to engage an irrigation tube external to the introducer.

31. The medical apparatus of claim 22, wherein the elongate sheath has a diameter that is less than 6 mm.

32. The medical apparatus of claim 22, wherein the viewing channel is sealed at the distal end of the elongate sheath and being open at the proximal end of the elongate sheath

33. An imaging system for imaging a body cavity, comprising:

an introducer sleeve including an elongated shaft having a proximal end and a distal end and including at least four lumens, the at least four lumens including a working channel, a viewing channel, a fluid inflow channel, and a fluid outflow channel, each of the working channel, the fluid inflow channel, and the fluid outflow channel having openings at proximal and distal ends thereof to create open channels therethrough, the viewing lumen having a sealed end at the distal end of the elongated shaft; and

an imaging device including a handle and an elongated member extending distally from the handle, the elongated member being configured to be inserted into the viewing lumen of the introducer sleeve and being configured to collect images therefrom, the handle being configured to releasably engage with the introducer sleeve to prevent relative movement therebetween.

34. The imaging system of claim 33, further comprising an imaging member disposed at a distal end of the elongated member of the imaging device, the imaging member being configured to be positioned in the viewing lumen and being configured to collect images through the sealed end of the viewing lumen.

35. The imaging system of claim 34, wherein the imaging member includes an active-pixel sensor array or a Complementary Metal-Oxide Semiconductor (CMOS) sensor.

36. The imaging system of claim 33, further comprising a transparent member configured to seal the sealed end of the viewing lumen.

37. The imaging system of claim 33, wherein the working channel is configured to receive a surgical tool through the proximal end of the elongated shaft and extendable out of the distal end of the elongated shaft.

38. The imaging system of claim 33, wherein the imaging device includes a power source operably engaged with the imaging device.

39. The imaging system of claim 33, wherein the imaging device includes a light source.

40. An imaging system, comprising:

an inserter sleeve including an elongate shaft having distal and proximal ends and at least four lumens extending therebetween, the sleeve having an engagement member positioned on the proximal end of the elongate shaft, and the at least four lumens including a working channel, a viewing channel, and two fluid channels; and

an imaging device including a handle and an elongate imaging member extending distally from the handle, the elongate imaging member being configured to be inserted into the viewing channel of the elongate shaft of the biopsy sleeve and being configured to take images therefrom, the handle being configured to engage with the engagement member of the sleeve.

41. The system of claim 40, wherein the imaging device includes a flexible CMOS fiberscope with an internal light source.

42. The system of claim 40, wherein each of the at least four lumens have openings on proximal and distal ends thereof to create open channels therethrough.
