Systems and methods for percutaneous drainage

A catheter for percutaneous drainage of a drainage site, comprising:

• a catheter wall extending from a proximal end portion of the catheter to a distal end portion of the catheter, the distal end portion of the catheter configured for placement within the drainage site;
• a septum disposed within the catheter wall and extending from the proximal end portion of the catheter to the distal end portion of the catheter;
• wherein the distal end portion includes a distal tip of the catheter, the septum extending completely to the distal tip of the catheter;
• a drain lumen defined by a first portion of the catheter wall and the septum, and extending from the proximal end portion of the catheter to the distal end portion of the catheter;
• and
• a flush lumen defined by a second portion of the catheter wall and the septum, and extending from the proximal end portion of the catheter to the distal end portion of the catheter, wherein the flush lumen is separated from the drain lumen by the septum;
• wherein the septum has at least one septal hole disposed therein proximate to the distal end portion of the catheter such that the drain lumen and the flush lumen are in communication via the at least one septal hole;
• wherein the catheter wall has at least one wall hole disposed therein proximate to the distal end portion of the catheter such that the drain lumen is in communication with the drainage site when the distal end portion is placed within the drainage site;
• wherein each wall hole has a corresponding septal hole;
• and
• wherein each wall hole is aligned with each corresponding septal hole such that each wall hole is positioned between 1 mm and 6.5 mm of the corresponding septal hole along the longitudinal axis.

A method of percutaneous drainage of a drainage site, comprising:

• inserting a catheter into the drainage site, the catheter including
• a catheter wall extending from a proximal end portion of the catheter to a distal end portion of the catheter, the distal end portion of the catheter configured for placement within the drainage site;
• a septum disposed within the catheter wall and extending from a proximal end portion of the catheter to a distal end portion of the catheter;
• a drain lumen defined by a first portion of the catheter wall and the septum, and extending from the proximal end portion of the catheter to the distal end portion of the catheter;
• and
• a flush lumen defined by a second portion of the catheter wall and the septum, and extending from the proximal end portion of the catheter to the distal end portion of the catheter, wherein the flush lumen is separated from the drain lumen by the septum;
• wherein the septum has at least one septal hole disposed therein proximate to the distal end portion of the catheter such that the drain lumen and the flush lumen are in communication via the at least one septal hole;
• wherein the catheter wall has at least one wall hole disposed therein proximate to the distal end portion of the catheter such that the drain lumen is in communication with the drainage site when the distal end portion is placed within the drainage site;
• wherein each of the wall holes has a corresponding septal hole;
• and
• wherein each wall hole is aligned with the corresponding septal hole such that each wall hole is positioned between 1 mm and 6.5 mm of the corresponding septal hole along the longitudinal axis;
• withdrawing fluid from the drainage site via the drain lumen;
• identifying an occlusion in the drain lumen and;
• flushing a flush fluid through the flush lumen and into the drain lumen via the at least one septal hole and thereby removing the occlusion.

A system for percutaneous drainage of a drainage site, comprising:

• a catheter having
• a catheter wall extending from a proximal end portion of the catheter to a distal end portion of the catheter, the distal end portion of the catheter configured for placement within the drainage site,
• a septum disposed within the catheter wall and extending from a proximal end portion of the catheter to a distal end portion of the catheter, wherein the distal end portion includes a distal tip of the catheter, the septum extending completely to the distal tip of the catheter;
• a drain lumen defined by a first portion of the catheter wall and the septum, and extending from the proximal end portion of the catheter to the distal end portion of the catheter, and
• a flush lumen defined by a second portion of the catheter wall and the septum, and extending from the proximal end portion of the catheter to the distal end portion of the catheter, wherein the flush lumen is separated from the drain lumen by the septum, wherein the septum has a plurality of septal holes in the septum along a longitudinal axis of the catheter;
• a drain tube having a first end portion coupled to the drain lumen at the proximal end portion of the catheter, and a second end portion coupled to a waste collection container;
• a first pump coupled to the drain tube between the first end portion of the drain tube and the second end portion of the drain tube;
• a flush tube having a first end portion coupled to the flush lumen at the proximal end portion of the catheter, and a second end portion coupled to a flush material container having a flush material disposed therein;
• a second pump coupled to the flush tube between the first end portion of the flush tube and the second end portion of the flush tube;
• and
• a controller coupled to the first pump and the second pump for controlling the first pump and the second pump;
• wherein the first portion of the catheter wall has at least a first wall hole disposed therein proximate to the distal end portion of the catheter such that the drain lumen is in communication with the drainage site when the distal end portion of the catheter is placed within the drainage site;
• wherein the second portion of the catheter wall has at least a second wall hole disposed therein proximate to the distal end portion of the catheter such that the flush lumen is in communication with the drainage site when the distal end portion of the catheter is placed within the drainage site;
• wherein each wall hole has a corresponding septal hole of the plurality of septal holes;
• and
• wherein each wall hole is aligned with the corresponding septal hole such that each wall hole is positioned between 1 mm and 6.5 mm of the corresponding septal hole along the longitudinal axis.
