Methods for performing endovascular procedures are described herein. The methods may comprise advancing an expandable member of a blood flow control device to a target location in a blood vessel of a patient, and rotating a circular gear positioned at least partially within a housing of a controller via the controller communicably coupled to the blood flow control device. Rotating the circular gear may translate a linear gear of a syringe pump fluidly coupled to the expandable member thereby adjusting a volume of the expandable member. Various blood flow control devices, control systems, and fluid delivery systems are also described herein. The fluid delivery systems may include a pump configured for manual or automated delivery of fluids, or configured to switch between automated and manual modes of delivery. The pump may be a syringe pump that utilizes a rack and pinion system, a motor, and a sensor to track the position and/or movement of a component of the syringe pump during fluid transfer. Alternatively, the pump may be a pressure differential pump that includes a flow restrictor and a pressure sensor that controls delivery of fluid from a fluid reservoir. Systems and methods including the syringe and pressure differential pumps are also described.

Systems and methods for blood flow control are described herein. In some variations, a blood flow control system may comprise a blood flow control device. The blood flow control device may be placed within a body of a patient and may comprise an expandable member and a sensor. The sensor may be configured to measure at least one of a physiologic condition of the patient and a pressure associated with the expandable member. The blood flow control system may include at least one controller communicably coupled to the sensor to: receive data indicative of at least one of the physiologic condition of the patient and the pressure associated with the expandable member from the sensor, compare the received data with target data, identify at least one error based on the comparison, and in response to identifying the error, inhibit at least one function of the blood flow control system.

Disclosed are systems and methods for reducing blood pressure variability in a patient. The system includes an endovascular catheter having an expandable element and one or more blood pressure sensors, and a computer/processing unit configured to receive blood pressure measurements and determine a blood pressure variability metric. Upon determining that the blood pressure variability metric exceeds a given blood pressure variability threshold or falls outside a predefined range, the computer/processing unit directs a catheter controller to adjust the size of the expandable element of the catheter, thereby modulating blood pressure and reducing blood pressure variability.

Devices and methods for visibly highlighting areas of a region including an imager configured to image the region with a sensitivity to at least one of wavelength, light level, or contrast greater than the human eye, an overlay element configured to visibly highlight areas of the region and registered to the imager to produce alignment of imaged features with highlighted features at the same location on the region, and at least one of a controller executing a program or logic configured to process acquired images from the imager to identify areas of the region determined not visible to the human eye, and control the overlay element to visibly highlight those areas on the region.

Devices and methods for producing a highlighted overlay of a region, including an illumination source configured to illuminate the region at a bandwidth containing a first wavelength at a working distance, an imager at a working distance configured to image the illuminated region at a bandwidth containing a second wavelength, where the first and second bandwidths and wavelengths are not visible, a visible light projector configured to illuminate the region and registered to the imager to produce alignment of imaged feature with projected features at the same location on the region, and a controller executing a program configured to filter acquired images from the imager to identify areas of the region of a predetermined light intensity, and control the projector to visibly highlight those areas on the region.
