Handle with features to secure a catheter assembly to an endoscope

A dilation catheter system, wherein the dilation catheter system comprises:

• (a) a body, wherein the body comprises an inner slot located between a distal end and a proximal end;
• (b) a guide member, wherein the guide member is coupled to the distal end of the body and extends distally therefrom;
• (c) a balloon dilation catheter, wherein the dilation catheter comprises an expandable balloon dilator;
• (d) an endoscope, wherein endoscope is disposed within the body and extends distally therefrom, wherein the endoscope extends alongside the guide member and exterior to the guide member;
• and
• (e) an actuator, wherein the actuator is slidably coupled with and surrounds an exterior surface of the body and a portion of the actuator protrudes radially inwardly within the inner slot, wherein the actuator is translatable along the inner slot of the body between a proximal position and a distal position, wherein the actuator is coupled with the balloon dilation catheter within the inner slot such that translation of the actuator is communicated to the balloon dilation catheter.

A dilation system, wherein the dilation system comprises:

• (a) a body, wherein the body includes an internal channel and an external surface;
• (b) a guide member, wherein the guide member is coupled to the distal end of the body and extends distally therefrom;
• (c) a dilation catheter, wherein the dilation catheter comprises an expandable balloon dilator, wherein the dilation catheter is configured to translate relative to the guide member;
• (d) an endoscope, wherein endoscope is disposed within the body and extends distally therefrom, wherein the endoscope extends alongside the guide member and exterior to the guide member;
• (e) an actuator, wherein the actuator surrounds the external surface of the body, wherein a portion of the actuator protrudes radially inwardly into the internal channel of the body to couple the actuator to the dilation catheter, wherein the actuator is configured to translate along the external surface and within the internal channel of the body from a proximal position to a distal position;
• wherein the balloon dilation catheter is coupled to the actuator within the internal channel such that the actuator is translatable to thereby advance the expandable balloon dilator;
• and
• wherein the expandable balloon dilator is configured to be disposed within the guide member when the actuator is in the proximal position, wherein the expandable balloon dilator is configured to extend beyond the guide member when the actuator is in the distal position.
