A method of operating a blood pump that is purged with a purge solution that contains a pH controlling and buffering agent combined with aqueous dextrose and a reduced amount of heparin or no heparin. The blood pump has a gap between a shaft and housing through which the purge solution flows. In operation, the purge solution exits the housing and is discharged into the patient. The purge solution is therefore required to perform lubricating and heat transfer functions in the pump yet be biocompatible with the patient.
An access sleeve can be attached to a medical device having first and second ends, the first end being positioned inside of a patient and the second end being positioned external to a patient. The access sleeve can include a tubular sleeve body having first and second open ends that define a first lumen extending along a longitudinal axis of the sleeve body. An opening in the sleeve body can connect the first lumen to an outer surface of the sleeve body. The access sleeve can be selectively attached to the medical device (e.g., catheter of a heart pump) and inserted into the access site when the medical device is positioned in the patient. The access sleeve can maintain vascular access to a patient's access site such as an arteriotomy and can be removed without disturbing the position of the medical device.

A web-based interface enables medical personnel to remotely monitor medical devices. A monitoring system records operational data and alarms from the medical devices in a file. However, since network connections between the medical devices and the monitoring system are intermittent, the file does not contain a contiguous stream of data for each medical device. The file pauses recording during gaps in network connectivity. The system displays current data, as well as a list of alarms. If medical personnel wish to view more detail about an earlier time or one of the alarms, the system calculates where in the file the medical device data was recorded. This calculation accounts for the discontiguous nature of the data. The system uses times the network connection is made and broken to calculate an index into the file that corresponds to the time of the user-selected alarm.

A blood flow rate measurement system measures fluid flow rate in a blood vessel having a catheter-based heart pump inserted therein, without relying on measurements of electric current drawn by a motor that drives the heart pump. A turbine is disposed at or near a distal end of the heart pump catheter. Blood or other fluid flowing through the blood vessel urges blades of the turbine to rotate. The turbine is mechanically coupled to a signal generator, which generates a signal indicative of a rotational speed of the turbine, which is dependent, at least in part, on speed of the fluid flowing through the blood vessel. A tachometer, external to the body of the patient, calculates the blood flow rate from the rotational speed of the turbine. In some cases, the blades are collapsible, to reduce diameter of the turbine, thereby facilitating insertion of the system into the blood vessel.
