Abstract

Systems and methods for selective auto-retroperfusion along with regional mild hypothermia. In at least one embodiment of a system for providing a retroperfusion therapy to a venous vessel of the present disclosure, the system comprises a catheter for controlling blood perfusion pressure, the catheter comprising a body having a proximal open end, a distal end, a lumen extending between the proximal open end and the distal end, and a plurality of orifices disposed thereon, each of the orifices in fluid communication with the lumen, and at least one expandable balloon, each of the at least one expandable balloons coupled with the body, having an interior that is in fluid communication with the lumen, and adapted to move between an expanded configuration and a deflated configuration, and a flow unit for regulating the flow and pressure of a bodily fluid, and a regional hypothermia system operably coupled to the catheter, the regional hypothermia system operable to reduce and/or regulate a temperature of the bodily fluid flowing therethrough.

Claims (45)

1. A system, comprising:

a catheter for controlling blood perfusion pressure, the catheter comprising:

a body having a plurality of orifices, each of the orifices in fluid communication with a lumen of the body, and

at least one expandable balloon, each having an interior that is in fluid communication with the lumen, and adapted to move between an expanded configuration and a deflated configuration;

a flow unit comprising at least one sensor and configured to regulate pressure of a bodily fluid and configured to be regulated by a remote module based upon data obtained by the at least one sensor; and

a regional hypothermia system operably coupled to the catheter, the regional hypothermia system operable to reduce and/or regulate a temperature of the bodily fluid flowing therethrough.

2. The system of claim 1 , wherein the regional hypothermia system is further operable to reduce and/or regulate a temperature of a portion of a mammalian body, the portion selected from the group consisting of a vessel, a tissue, and an organ.

3. The system of claim 1 , wherein the regional hypothermia system comprises a heat exchanger configured to reduce and/or regulate the temperature of the bodily fluid.

4. The system of claim 1 , wherein one or more components of the regional hypothermia system uses a cooling product to reduce and/or regulate the temperature of the bodily fluid.

5. The system of claim 1 , further comprising:

one or more temperature sensors coupled to the catheter, the one or more temperature sensors operable to detect the temperature of the bodily fluid.

6. The system of claim 5 , further comprising the remote module in wired or wireless communication with the one or more temperature sensors and operable to receive and process the detected temperature(s) to regulate, reduce, and/or increase the temperature of the bodily fluid by way of altering an operation of the regional hypothermia system.

7. The system of claim 1 , further comprising:

an arterial blood flow device comprising a proximal end, a distal end configured to couple with a proximal end of the flow unit, and an interior extending between the proximal end and the distal end, wherein the proximal end, the distal end and the interior each configured to allow arterial blood to flow therethrough.

8. The system of claim 1 , wherein the flow unit further comprises:

an elongated body having an open proximal end, an open distal end coupled with the open proximal end of the body of the catheter, an interior extending between the open proximal end and the open distal end of the elongated body, and a chamber surrounding at least a portion of the elongated body, the chamber adapted to expand and deflate and comprising an interior and at least one port in fluid communication with the interior of the chamber and adapted to couple with a fluid source, and

wherein the remote module automatically adjusts the flow unit to regulate the flow of pressure of the bodily fluid by automatically expanding or deflating the chamber of the elongated body based on the data gathered by the at least one sensor.

9. The system of claim 8 , wherein at least one of the at least one sensors of the flow unit is adapted to transmit the gathered data to the remote module.

10. The system of claim 1 , further comprising:

a connection assembly for providing a sterile environment, the connection assembly comprising:

a cover comprising a body portion, a limb component extending from the body portion, and an interior extending between the body portion and the limb component, the interior configured to encase the distal end of the elongated body of the flow unit and the proximal end of the body of the catheter therein;

at least one flushing port in fluid communication with a gas supply and the interior of the cover; and

at least one valve in fluid communication with the interior of the cover, the at least one valve adapted to drain gas from within the interior of the cover.

11. A system, comprising:

a catheter for controlling blood perfusion pressure, the catheter comprising:

a body having a plurality of orifices, each of the orifices in fluid communication with a lumen of the body, and
