Multi-channel catheter connection for anatomical manometry

A connector assembly for an anatomical manometry system, the anatomical manometry system comprising a catheter being generally elongate in shape, the catheter having a distal end and a proximal end, the distal end being configured for insertion into a patient lumen for measuring a pressure, the proximal end being opposite to the distal end, the catheter further including a plurality of catheter lumens permitting passage of a pressure transmission medium, the catheter further comprising a plurality of balloons on the distal end, each balloon being fluidly coupled to one of the plurality of catheter lumens so as to receive the pressure transmission medium, each balloon being configured to be inflatable and/or deflatable, the connector assembly comprising:

• a connector interface that receives the proximal end of the catheter therethrough;
• a manifold having a plurality of channels, each channel being aligned with a respective catheter lumen when the catheter is connected to the connector interface permitting passage of the pressure transmission medium toward the catheter lumen,
• the connector interface being rotatable relative to the proximal end of the catheter to lock the catheter to the manifold;
• and
• a charging mechanism coupled to the catheter and the connector assembly, the charging mechanism comprising a plurality of chargers commonly housed on a charger housing, each charger being fluidly coupled to plurality of channels of the manifold,
• the rotation of the connector interface relative to the manifold axially displacing the manifold relative to the charger housing so as to actuate each charger positioned on the charger housing, each charger displacing a fluid in the fluid chamber when actuated by the manifold,
• the chargers discharging the displaced fluid to charge a corresponding balloon, whereby displacement of the fluid is caused by movement of the charger when actuated by the manifold,
• the commonly actuated chargers further permitting charging each balloon of the plurality of balloons.

An anatomical manometry catheter system, comprising:

• a catheter being generally elongate in shape and having
• a central axis,
• a distal end and a proximal end, the distal end being configured for insertion into a patient lumen for measuring a pressure, the proximal end being opposite to the distal end,
• a plurality of catheter lumens permitting passage of a pressure transmission medium,
• a plurality of balloons on the distal end, each balloon being fluidly coupled to one of the plurality of catheter lumens so as to receive the pressure transmission medium, each balloon being configured to be inflatable and/or deflatable;
• a connector assembly coaxially aligned with the catheter, the connector assembly being connectable to the proximal end of the catheter, the connector assembly having:
• a connector interface that receives the proximal end of the catheter, a manifold comprising a plurality of channels configured to deliver the pressure transmission medium therethrough toward a respective catheter lumen for inflating one or more balloons,
• the connector interface being rotatable relative proximal end of the catheter to lock the catheter to the manifold, and
• a charging mechanism fluidly coupled to the catheter, the charging mechanism comprising a plurality of chargers,
• whereby actuation of the plurality of chargers facilitates inflating each balloon of the plurality of balloons,
• each charger having a fluid chamber, the rotation of the connector interface relative to the manifold axially moving each charger of the plurality of chargers along the central axis and thereby displacing a fluid in the fluid chamber,
• the chargers discharging the fluid to charge a corresponding balloon, whereby rotation of the connector interface permits charging of each balloon of the plurality of balloons.
