Systems and methods for providing cavopulmonary support

摘要

Systems and methods for providing cavopulmonary support to a subject are provided that include and make use of a first inflatable extravascular cuff configured to be placed around a superior vena cava in the subject and a second inflatable extravascular cuff configured to be placed around an inferior vena cava in the subject. The system further includes a pump that is operably connected to both the first inflatable extravascular cuff and the second inflatable extravascular cuff, as well as a controller that is in communication with the pump. The controller receives one or more user-defined parameters and, in response to the user-defined parameters, independently controls the inflation and deflation of the first inflatable extravascular cuff and the second inflatable extravascular cuff to provide cavopulmonary support.

主权项

1. A system for providing cavopulmonary support to a subject, comprising:
a first inflatable extravascular cuff configured to be placed around a superior vena cava in the subject; a second inflatable extravascular cuff configured to be placed around an inferior vena cava in a subject; a pump operably connected to the first inflatable extravascular cuff and the second inflatable extravascular cuff; and a controller in communication with the pump, the controller for receiving one or more user-defined parameters and for independently controlling the inflation and deflation of the first inflatable extravascular cuff and the second inflatable extravascular cuff in response to the user-defined parameters, wherein the user-defined parameters are directed to a selected timing for inflating and deflating the first inflatable extravascular cuff, the second inflatable extravascular cuff, or both; and wherein the first inflatable extravascular cuff and the second inflatable extravascular cuff are configured to inflate and deflate peristaltically in response to the user-defined parameters to provide cavopulmonary support.
