Medical device with integrated instrument and related methods

A medical device, comprising:

• a tube having a proximal end and a distal end, and comprising a lumen extending from the proximal end to the distal end;
• a cap at the distal end of the tube, the cap having a distal opening corresponding to the lumen;
• a sheath at least partially disposed within the lumen;
• an instrument disposed within the sheath, wherein the sheath and the instrument are non-removable from the medical device;
• an instrument actuation mechanism comprising a sheath actuator and an instrument actuator;
• and
• a single handle connected to the proximal end of the tube and housing the instrument actuation mechanism,
• wherein a proximal end of the sheath is affixed to the sheath actuator and the sheath actuator is configured to move between a first position and a second position on the single handle to control an extension and retraction of the sheath in which the instrument is disposed relative to the tube via the distal opening, and
• wherein a proximal end of the instrument is affixed to the instrument actuator and the instrument actuator is configured to move between a third position and a fourth position on the single handle to control an extension and retraction of a distal end of the instrument relative to the sheath to transition the distal end of the instrument between a collapsed state and an expanded state.

A medical device, comprising:

• a tube having a proximal end and a distal end, and comprising a lumen extending from the proximal end to the distal end;
• a cap at the distal end of the tube, the cap having a distal opening corresponding to the lumen;
• a handle connected to the proximal end of the tube and housing an actuation mechanism configured to be moved between a first position and a second position on the handle;
• and
• a wire having a first end and a second end, wherein the wire is at least partially disposed in the lumen, the first end of the wire is attached to a fixation point on a distal-facing surface of the cap, the wire extends from the fixation point through a second distal opening of the cap, different from the distal opening corresponding to the lumen, into the handle via the tube, and a second end of the wire opposite the first end of the wire is affixed to the actuation mechanism,
• wherein, when the actuation mechanism is in the first position, a first portion of the wire from the fixation point to the second distal opening forms a loop in a collapsed state that at least partially contacts the distal-facing surface, and
• wherein, when the actuation mechanism is in the second position, a second portion of the wire is extended from the tube via the second opening to transition the loop to an expanded state.
