Catheter locking mechanisms and methods for same

A locking catheter system comprising:

• a first catheter;
• a second catheter;
• a locking mechanism coupled with the first and second catheters, the locking mechanism includes:
• a lock body having a system lumen extending through the lock body, wherein the first and second catheters are received in the system lumen;
• a system channel extending from the system lumen, the system channel configured to receive one or more of the first or second catheters;
• a locking channel extending from the system lumen, the locking channel including a lock element, the locking channel configured to receive one or more of the first or second catheters;
• and
• wherein the locking mechanism includes locked and unlocked configurations:
• in the unlocked configuration the first and second catheters are received in the system channel, and the first and second catheters are movable relative to the lock body;
• and
• in the locked configuration at least the second catheter is received in the locking channel, the second catheter is statically coupled with the lock body, and the first catheter is movable relative to the lock body.

A method of locking one or more catheters comprising:

• navigating first and second catheters to a specified location;
• conducting a procedure with one or more of the first or second catheters proximate the specified location;
• and
• withdrawing the second catheter from the specified location while maintaining the first catheter at the specified location, wherein withdrawing includes:
• moving a second catheter portion of the second catheter from a system channel to a locking channel of a locking mechanism;
• statically coupling the second catheter portion to the locking mechanism with a lock element associated with the locking channel;
• retracting the locking mechanism, and the second catheter is retracted with the locking mechanism based on the static coupling;
• moving the locking mechanism and the second catheter relative to the first catheter, the first catheter within the system channel.
