DIAPHRAGM ENTRY FOR POSTERIOR SURGICAL ACCESS
Methods and devices described herein facilitate improved treatment of body organs.
1 . An access device for creating a temporary cavity between organs in a body, the access device comprising:
an elongate member having a working channel extending therethrough, the elongate member having a distal portion adapted for insertion into the body and a proximal portion, the elongate member having a column strength to allow insertion of the distal portion between organs; and
a slot shaped opening at a distal end of the elongate member, where the working channel exits the elongate member at the slot shaped opening comprising a slotted portion extending along a wall of the elongate member.
2 .- 4 . (canceled)
5 . The access device of claim 1 , where the elongate member further comprises a second working lumen extending therethrough, the second working lumen being separate from the working channel and, where the working lumen exits the elongate member at a separate opening.
6 . The access device of claim 5 , where at the proximal portion of the elongate member, the working channel and second working lumen are staggered.
7 . The access device of claim 1 , where at the working lumen is smaller in size than the working channel.
8 . The access device of claim 1 , where at the working lumen is the same size as the working channel.
9 . (canceled)
10 . The access device of claim 1 , further comprising a braided support member along the distal portion of the elongate member.
11 . The access device of claim 1 , where the braided support member is located within a wall of the elongate member.
12 . The access device of claim 1 , further comprising a valve in fluid communication with the working lumen.
13 . The access device of claim 12 , where the valve is located over a proximal opening of the elongate member.
14 . The access device of claim 1 , where the proximal portion of the elongate member is adapted to allow manipulation of the access device outside of the body.
15 . The access device of claim 14 , where the proximal portion of the elongate member comprises a handle that allows for manipulation of the access device.
16 . The access device of claim 1 , where the elongate member is tapered towards the distal portion.
17 . The access device of claim 1 , where at the proximal portion, the working channel is tapered along a proximal end of the elongate member to increase an area through which instrumentation enters the working channel.
18 . The access device of claim 1 , where a length of the elongate member from a proximal end to the slot shaped opening is 30 cm.
19 . The access device of claim 1 , further comprising a shapeable support member located elongate member, where the shapeable support member causes the elongated member to retain a shape of the shapeable support member.
20 . The access device of claim 19 , where the elongated member further comprises a support lumen and where the shapeable support member is slidably located within the support lumen.
21 .- 22 . (canceled)
23 . The access device of claim 1 , where the elongate member further comprises at least a first inflation lumen therein, and where the first expandable member comprises a first balloon having an interior in fluid communication with the inflation lumen, where the first balloon is adapted to inflate to separate the body organs.
24 .- 36 . (canceled)
37 . The access device of claim 23 , where the elongate member comprises a shapeable material.
38 . The access device of claim 23 , where the distal portion of the member is curved or angled.
39 . The access device of claim 23 , where the elongate member further comprises at least one suction lumen located in a wall thereof, and where the suction lumen terminates in a suction port located at the distal end of the elongate lumen.
40 . The access device of claim 23 , where the elongate member further comprises at least one suction lumen located in the working channel, and where the suction lumen terminates in a suction port located at the distal end of the working channel.
41 . The access device of claim 1 , further comprising at least one visual element located in a distal portion of the elongate member.
42 . The access device of claim 25 , where the visual element is a fiber optic scope.
43 . The access device of claim 1 , where the elongate member comprises a non-circular cross-section.
44 . The access device of claim 43 , where the cross-section of the elongate member is oval.
45 . The access device of claim 43 , where the cross-section of the elongate member is rectangular.
46 . The access device of claim 43 , where the elongate member comprises at least a first planar surface.
47 .- 48 . (canceled)
49 . The access device of claim 46 , where the distal end of the elongate member comprises a slot in the planar surface.
50 . The access device of claim 1 , where the working channel of the elongate member comprises a non-circular shape having a height and width, such that the working channel width is not equal to the working channel height.
