Device for treating bleeding
A system for treating internal bleeding via application of a heated irrigant, such that the heated irrigant is delivered at a flow rate of between 2 cc/s and 12 cc/s and at a temperature of between 46 degrees Celsius and 52 degrees Celsius.
1 . A system for treating internal bleeding, comprising:
a reservoir configured to hold an irrigant;
a first impeller disposed within the reservoir, and configured to recirculate the irrigant within the reservoir;
a second impeller disposed within the reservoir and configured to motivate the irrigant from the reservoir;
a motor that simultaneously spins both the first impeller and the second impeller;
a heating element configured to heat the irrigant to generate a heated irrigant as the irrigant flows through and recirculates within the reservoir, wherein the heated irrigant is configured to arrest the internal bleeding upon delivery of the heated irrigant to a treatment area; and
a treatment catheter configured to receive the heated irrigant from the reservoir, the treatment catheter having an irrigant outlet and an irrigant inlet located at a distal portion of a catheter body of the treatment catheter, wherein the irrigant outlet is located farther distally on the catheter body than the irrigant inlet;
wherein the system is configured to deliver the heated irrigant from the irrigant outlet to the treatment area where there is the internal bleeding such that the heated irrigant is delivered at a flow rate of between 2 cc/s and 12 cc/s and a temperature of between 46 degrees Celsius and 52 degrees Celsius.
2 . The system of claim 1 wherein the heating element is configured to heat the irrigant via volumetric heating.
3 . The system of claim 1 wherein the heating element is configured to heat the irrigant via application of radio-frequency energy.
4 . The system of claim 1 wherein the treatment catheter, the heating element, or both include one or more sensors.
5 . The system of claim 4 further comprising a controller, wherein the controller is configured to receive data feedback from the one or more sensors.
6 . The system of claim 5 wherein the controller controls the heating element using the data feedback.
7 . The system of claim 5 , wherein the controller controls the motor using the data feedback.
8 . The system of claim 1 wherein the flow rate is between 2 cc/s and 6 cc/s.
9 . The system of claim 1 wherein the temperature is between 48 degrees Celsius and 52 degrees Celsius.
10 . The system of claim 1 , wherein the second impeller is configured to motivate the heated irrigant from the reservoir into the treatment catheter.
11 . A system for treating internal bleeding, comprising:
a treatment catheter having an irrigant outlet and an irrigant inlet located at a distal portion of a catheter body of the treatment catheter, wherein the irrigant outlet is located farther distally on the catheter body than the irrigant inlet; and
a heating apparatus connected the treatment catheter, wherein the heating apparatus includes:
a reservoir configured to hold an irrigant;
a first impeller disposed within the reservoir and configured to recirculate the irrigant within the reservoir;
a second impeller disposed within the reservoir and configured to motivate the irrigant from the reservoir into the treatment catheter;
a motor that simultaneously spins both the first impeller and the second impeller; and
a heating element configured to heat the irrigant to a temperature suitable to arrest the internal bleeding as the irrigant flows through the heating element to the treatment catheter;
wherein the system is configured to deliver heated irrigant from the irrigant outlet to a treatment area where there is the internal bleeding such that the heated irrigant is delivered at a flow rate of between 2 cc/s and 12 cc/s and at a temperature of between 46 degrees Celsius and 52 degrees Celsius.
