Abstract

A medical device may comprise a handle portion; an insertion portion having a proximal end portion at the handle portion, wherein the insertion portion includes a lumen therein and a distal end having a distal opening in communication with the lumen; and a member disposed within the lumen, the member having a distal end portion with an imaging device. The member may be configured to transition between a first configuration and a second configuration. In the first configuration, the imaging device may face distally, and, in the second configuration, the imaging device may face proximally. Extending the distal end portion of the member distally past the distal opening may cause the member to transition from the first configuration to the second configuration.

First claim

We claim:

1 . A medical system comprising:
an endoscope, including:
a handle and a shaft extending from the handle, wherein the shaft of the endoscope includes a working channel; and
a medical device, including:
a member having a shaft, an imaging device, and an anchor member;
a tool having a shaft; and
a tether, comprising:
a first surface configured to slidably engage with the shaft of the member, wherein the first surface defines a first lumen for engaging the shaft of the member and the first lumen includes a first opening; and
a second surface, wherein the second surface defines a second lumen and the second lumen includes a second opening, wherein the second surface fixedly engages with the shaft of the tool to secure the tether to the tool as the tether slides relative to the member;

wherein each of the first opening and the second opening is on a side surface of the tether and extends from a proximal portion of the tether to a distal portion of the tether; wherein the member, the tool, and the tether are configured to be inserted together through the working channel of the shaft of the endoscope, such that an entirety of the tether is distal of a distalmost opening of the working channel of the endoscope.

2 . The medical device of claim 1 , wherein the shaft of the member is keyed to the first surface of the tether.

3 . The medical device of claim 1 , wherein the shaft of the tool is keyed to the second surface of the tether.

4 . The medical device of claim 1 , wherein a width of the first opening is smaller than a diameter of the shaft of the member, and wherein a width of the second opening is smaller than a diameter of the shaft of the tool.

5 . The medical device of claim 1 , wherein the anchor member includes at least one of an inflatable member, a clip, and a coil.

6 . The medical device of claim 1 , wherein the member includes a lumen, wherein a second member is disposed within the lumen, the second member including at least one of an inflatable member, a forceps, a snare, a clip, a basket, a tome, a suction device, and a probe.

7 . The medical device of claim 1 , wherein the imaging device is disposed on a side surface proximal to a distal end of the member.

8 . The medical device of claim 1 , wherein a steering mechanism is disposed along an external surface of the shaft of the tool for a portion of a length of the shaft of the tool.

9 . The medical device of claim 8 , wherein the steering mechanism of the tool is disposed within a lumen of the shaft of the tool for a portion of a length of the shaft of the tool and is disposed outside of the shaft of the tool at another portion of a length of the shaft.

10 . The medical device of claim 1 , wherein the shaft of the tool includes a surface defining a lumen, wherein the lumen includes an opening extending along an entire length of the shaft of the tool, and wherein the second surface of the tether is configured to engage with the surface of the shaft of the tool.

11 . The medical device of claim 1 , wherein the shaft of the tool includes a surface defining a lumen, wherein the lumen includes an opening extending along a distal portion of the shaft of the tool, and wherein the second surface of the tether is configured to engage with the surface of the shaft of the tool.

12 . A medical device comprising:
a member having a shaft, an imaging device, and an anchor member; a tool having a shaft and a steering mechanism, wherein at least a portion of the steering mechanism is disposed within a lumen of the shaft of the tool; and a tether comprising:
a first lumen, wherein the first lumen is configured so as to slidably engage with the shaft of the member; and
a second lumen, wherein the second lumen fixedly engages with the shaft of the tool to secure the tether to the tool as the tether slides relative to the member, such that the tether is stationary with respect to the tool and longitudinal movement of the tool causes longitudinal movement of the tether, wherein the second lumen includes an opening, wherein the opening extends from a proximal portion of the tether to a distal portion of the tether, wherein a width of the opening is smaller than a diameter of the shaft of the tool.

13 . The medical device of claim 12 , wherein the steering mechanism is disposed along an external surface of the shaft of the tool for a portion of a length of the shaft of the tool.

14 . The medical device of claim 12 , wherein the anchor member includes at least one of an inflatable member, a clip, and a coil.

15 . The medical device of claim 12 , wherein the opening is on a side surface of the tether and extends from a proximal portion of the tether to a distal portion of the tether.

16 . The medical device of claim 12 , wherein the imaging device is disposed within a lumen of the shaft, and wherein the member, the tool, and the tether are configured to be inserted through a working channel of a shaft of an endoscope and extended out of a distalmost opening of the working channel of the shaft of the endoscope, such that an entirety of the tether is distal to the distalmost opening of the working channel of the shaft of the endoscope.

17 . A medical device comprising:
a member having a shaft, an imaging device, a steering mechanism, and an anchor member; a tool having a shaft, wherein the steering mechanism of the tool is disposed within a lumen of the shaft of the tool for a portion of a length of the shaft of the tool and is disposed outside of the shaft of the tool at another portion of the length of the shaft; and a tether coupled to only a portion of the shaft of the member and only a portion of the shaft of the tool, comprising:
a first surface, wherein the first surface is configured so as to slidably engage with the shaft of the member, and wherein the first surface defines a first lumen for engaging the shaft of the member; and
a second surface, wherein the second surface is configured so as to fixedly engage with the shaft of the tool to secure the tether to the tool as the tether slides relative to the member and the second surface defines a second lumen for engaging the shaft of the tool;
wherein the first lumen includes a first opening, wherein the second lumen includes a second opening, wherein each of the first opening and the second opening is on a side surface of the tether, and wherein each of the first opening and the second opening extends from a proximal portion of the tether to a distal portion of the tether, wherein the shaft of the member has a distalmost end that is proximal of or even with the second opening;
wherein a width of the first opening is smaller than a diameter of the shaft of the member, and wherein a width of the second opening is smaller than a diameter of the shaft of the tool.

18 . The medical device of claim 17 , wherein the anchor member includes at least one of an inflatable member, a clip, and a coil.

19 . The medical device of claim 17 , wherein the imaging device is disposed within a lumen of the shaft and on a side surface proximal to a distal end of the member.
