Abstract
Disclosed is a device for providing resuscitation or suspended state through redistribution of cardiac output to increase supply to the brain and heart for a patient. The device includes an electrically controllable redistribution component attachable to the patient to provide redistribution of the cardiac output to increase supply to the brain and heart. The redistribution component, following a predefined reaction pattern based on an electrical signal, and computer means configured to: receive a patient data which identifies physiological and/or anatomical characteristics of the patent; and provide the electrical signal for the redistribution component based on the patient data or a standard response. The device may provide mechanisms to protect the aorta and the remaining anatomy of the patient from inadvertent damage caused by the disclosed device in any usage scenario of either correct intended usage or unintended usage. Also disclosed is a method for providing resuscitation or suspended state.
Core Innovation
The invention provides a device for providing resuscitation or suspended state through redistribution of cardiac output to increase supply to the brain and heart. The device uses an electrically or manually controllable occlusion device in the form of an aortic expansion member attachable to the patient, together with an inflation means connected to expand the aortic expansion member. The aortic expansion member follows a predefined reaction pattern based on an electrical signal.
Computer means are configured to receive patient data that identifies physiological and/or anatomical characteristics of the patient. The computer means provides the electrical signal for controlling the aortic expansion member and/or presents the physiological and/or anatomical characteristics for a user based on the patient data. In this way, the control of redistribution is responsive to patient-specific characteristics.
An adaptable tissue protection mechanism is configured to determine a blood pressure or blood flow present in a blood vessel of the patient, determine a characteristic of the aortic expansion member defining a degree of expansion based on the determined blood pressure or blood flow, and provide an electrical signal for controlling the inflation means in accordance with the determined aortic expansion member characteristics so as to avoid damage to the patient. The expandable aortic occlusion member therefore supports redistribution while incorporating tissue protection based on blood pressure or blood flow.
The electrical signal specifies one or more of a degree of expansion, a timing of expansion, a duration of expansion, and/or a timing of contraction of the aortic expansion member. The device includes means for specifying degree of expansion and/or timing of expansion and/or determining duration of expansion and/or timing of contraction, enabling the aortic expansion member to be controlled by the electrical signal and predefined reaction pattern for resuscitation or suspended state.
Claims Coverage
The partial content provides two independent claims. Across these independent claims, the core inventive features are patient-data-driven electrical control of an aortic expansion member to redistribute cardiac output to increase supply to the brain and heart, a predefined reaction pattern for the aortic expansion member, adaptable tissue protection based on blood pressure or blood flow and expansion degree, and electrical-signal specification of expansion degree, timing, duration, and contraction timing.
A patient-data-controlled electrically or manually controllable aortic expansion member for resuscitation or suspended state
A device comprising an electrically or manually controllable occlusion device in the form of an aortic expansion member attachable to the patient and configured to interact with the patient to provide redistribution of the cardiac output to increase supply to the brain and heart; an inflation means connected to the aortic expansion member for expanding the aortic expansion member; and the aortic expansion member following a predefined reaction pattern based on an electrical signal.
Computer means for receiving patient data and providing the electrical signal and/or presenting patient characteristics
Computer means configured to receive a patient data which identifies physiological and/or anatomical characteristics of the patient; and provide the electrical signal for controlling the aortic expansion member and/or for presenting the physiological and/or anatomical characteristics for a user based on the patient data.
Adaptable tissue protection mechanism based on blood pressure or blood flow and expansion degree
An adaptable tissue protection mechanism configured to determine a blood pressure or blood flow present in a blood vessel of the patient; determine a characteristic of the aortic expansion member defining a degree of expansion of the aortic expansion member based on the determined blood pressure or blood flow; and provide an electrical signal for controlling the inflation means in accordance with the determined aortic expansion member characteristics so as to avoid damage to the patient.
Electrical-signal specification of expansion degree and/or timing and/or duration and/or contraction timing
A device where the electrical signal specifies 1) a degree of expansion of and/or 2) a timing of expansion of and/or 3) duration of expansion of and/or 4) a timing of contraction of the aortic expansion member; and the device comprises means for specifying a degree of expansion of the expansion member and/or means for timing of the expansion of the expansion member and/or means for determining duration of expansion of the expansion member and/or means for timing of contraction of the expansion member.
Taken together, the independent claims cover a resuscitation/suspended-state device that redistributes cardiac output to increase supply to the brain and heart by occluding the aorta with an electrically or manually controllable aortic expansion member. Control is driven by computer means receiving patient data and providing an electrical signal consistent with a predefined reaction pattern, with adaptable tissue protection based on determined blood pressure or blood flow. The electrical signal further specifies one or more of expansion degree, expansion timing, expansion duration, and contraction timing.
Stated Advantages
