Abstract
Disclosed herein are devices and methods for introducing a plurality of instruments to a target site through a working channel. The working channel can include a surface adapted to guide one or more instruments into select positions. The working channel can be defined by a portion of a guide tube or tip that may be coupled with an endoscope.

A distal tip of a medical instrument, comprising:
- a body having a proximal end, a distal end, and a channel extending along a longitudinal axis therebetween, wherein the channel is at least partially defined by an instrument directing surface that is transverse to a longitudinal axis of the body, proximate to a distal end of the body, and proximal of the distal end of the body;
- wherein the body is configured such that, when a first instrument is inserted into the channel, the instrument directing surface contacts the first instrument and guides the first instrument into a first area, wherein, if a second instrument is inserted into the channel while the first instrument is present in the first area, the second instrument is guided to a second area, and wherein the instrument directing surface is deformable, such that, when the second instrument is inserted into the channel, contact between the second instrument and the instrument directing surface causes the instrument directing surface to change shape and allow passage of the second instrument into the second area.
A distal tip of a medical instrument, comprising:
- a body having a proximal end, a distal end, and a channel extending along a longitudinal axis therebetween, wherein the channel is at least partially defined by an instrument directing surface that is transverse to a longitudinal axis of the body and proximal of the distal end of the body, and wherein a portion of the channel distal to the instrument directing surface includes a first area for receiving a first instrument and a second area for receiving a second instrument;
- wherein, when the first instrument is inserted into the channel, the instrument directing surface contacts the first instrument and guides the first instrument into the first area, and wherein the instrument directing surface limits the first instrument from entering the second area, wherein, if the second instrument is inserted into the channel while the first instrument is disposed in the first area, the second instrument is guided into the second area by at least one of the first instrument or the instrument directing surface, and wherein the instrument directing surface is deformable, such that, when the second instrument is inserted into the channel, contact between the second instrument and the instrument directing surface causes the instrument directing surface to change shape and allow passage of the second instrument into the second area.
A distal tip of a medical instrument, comprising:
- a body having a proximal end, a distal end, and a channel extending along a longitudinal axis therebetween, wherein the channel is at least partially defined by an instrument directing surface that is transverse to a longitudinal axis of the body and proximal of the distal end of the body, and wherein a portion of the channel distal to the instrument directing surface includes a first area for receiving a first instrument and a second area for receiving a second instrument;
- wherein, when the first instrument is inserted into the channel, the instrument directing surface is configured to obstruct the first instrument from entering the second area, wherein, if the second instrument is inserted into the channel while the first instrument is disposed in the first area, the second instrument is guided into the second area by at least one of the first instrument or the instrument directing surface, and wherein the instrument directing surface is deformable, such that, when the second instrument is inserted into the channel, contact between the second instrument and the instrument directing surface causes the instrument directing surface to change shape and allow passage of the second instrument into the second area.
