Abstract
The disclosed invention provides a closed loop catheter system for treatment of pulmonary embolism with balloon tipped catheter insertion devices. The system includes a first catheter insertion device configured to be positioned at proximal segment of a designated pulmonary vein and a second catheter insertion device configured to be positioned at proximal segment of a designated pulmonary artery. The first and second catheter insertion devices each include a sheath defining at least one lumen therein and at least one balloon that is connected to the distal end of the sheath. The at least one balloon seals ostium of the pulmonary vein or ostium of the pulmonary artery when inflated and the first catheter insertion device is in use.
Claims19
A catheter system for pulmonary embolism with balloon tipped catheter insertion devices, comprising:
- a first catheter insertion device configured to be suitable for facilitating precise and safe cannulation of pulmonary veins, wherein the first catheter insertion device is configured to be connected to an infuser to supply fluid to the pulmonary veins, the first catheter insertion device comprising:
- a sheath that defines at least one lumen therein and has a distal end that is configured to be positioned at proximal segment of a designated pulmonary vein and a proximal end that is external to the patient;
- and
- at least one balloon that is positioned at the distal end of the sheath, wherein the at least one balloon is configured to seal ostium of the designated pulmonary vein when inflated;
- and
- a second catheter insertion device configured to be suitable for facilitating precise and safe cannulation of pulmonary arteries, wherein the second catheter insertion device is configured to be connected to an aspirator to aspirate materials from the pulmonary arteries, the second catheter insertion device comprising:
- a sheath that defines at least one lumen therein and has a distal end that is configured to be positioned at proximal segment of a designated pulmonary artery and a proximal end that is external to the patient;
- and
- at least one balloon that is positioned at the distal end of the sheath, wherein the at least one balloon is configured to seal the designated pulmonary artery when inflated.
A method of using a catheter system including a first catheter insertion device and a second catheter insertion device for pulmonary embolism, comprising:
- engaging a distal portion of a first catheter insertion device with an ostium and proximal segment of a designated pulmonary vein;
- inflating at least one balloon of the first catheter insertion device to seal the ostium of the designated pulmonary vein;
- positioning a distal portion of the second catheter insertion device within a proximal segment of a corresponding designated pulmonary artery;
- inflating at least one balloon of the second catheter insertion device to seal the designated pulmonary artery;
- performing infusion of fluid into the designated pulmonary vein through at least one lumen defined in a sheath of the first catheter insertion device by using an infuser connected to the first catheter insertion device;
- and
- performing aspiration of materials from the designated pulmonary artery through at least one lumen defined in a sheath of the second catheter insertion device by using an aspirator connected to the second catheter insertion device.
