Single lumen drainage catheter with extendable and retractable drains

A catheter, comprising:

• a primary drainage catheter comprising a housing with a common drain, the primary drainage catheter providing continuous fluid drainage from a patient;
• wherein the housing has a distal end portion, a proximal end portion, an exterior, and an interior space comprising a single unpartitioned lumen;
• wherein the common drain is coupled to the proximal end portion of the housing and is adapted for a fluid to flow through the common drain, wherein the common drain is attached the exterior portion of the housing;
• and
• a plurality of drains arranged within the single unpartitioned lumen with each drain of the plurality of drains having a proximal end, a distal end, and an interior space between the proximal end and the distal end, wherein each drain of the plurality of drains is adapted for the fluid to flow through the interior space between the proximal end and the distal end;
• wherein the common drain is in fluid communication with the single unpartitioned lumen of the interior space of the housing and with the plurality of drains;
• wherein the plurality of drains are adapted to be movable within the single unpartitioned lumen between an extended position with at least the distal end portions of the plurality of drains extending to the exterior of the housing and a retracted position with the plurality of drains being enclosed within the single unpartitioned lumen of the housing;
• and
• wherein with the plurality of drains in the extended position the plurality of drains provide a first plurality of paths for the fluid to flow between the common drain and the exterior of the housing;
• an internal connector having a proximal end portion, a proximal end surface, a distal end portion, and a distal end surface, wherein:
• the internal connector is enclosed within the single unpartitioned lumen and is selectively movable within the single unpartitioned lumen substantially between the proximal end portion of the housing and the distal end portion of the housing;
• the plurality of drains are coupled to the internal connector with the proximal ends of the plurality of drains coupled to the distal end portion of the internal connector and the distal end of the drains extending into the single unpartitioned lumen;
• and
• movement of the internal connector between the proximal end portion of the housing and the distal end portion of the housing causes the plurality of drains to move between the retracted position and the extended position;
• and,
• an elongated stylet having a proximal end portion, a distal end portion, and a distal end tip.
