A method for providing at least partial bypass of the heart to supplement the pumping function of the heart to thereby enable the surgeon to perform various surgical procedures thereon includes providing a circulatory assist system having a portable extracorporeal axial flow pump with a pump housing, a rotating pumping member disposed in the pump housing and inlet and outlet cannulated tubes respectively connected to inlet and outlet ports of the pump housing, accessing the patient's left atrium of the heart with the inlet cannulated tube, accessing the aorta with the outlet cannulated tube, actuating the rotating pumping member to draw oxygenated blood from the left atrium of the heart through the lumen of the inlet cannulated tube and into the inlet port of the pump housing whereby the pumping member imparts mechanical energy to the oxygenated blood passing through the pump housing and directs the oxygenated blood through the outlet port and through the lumen of the outlet cannulated tube to be transferred by the aorta to the systemic arteries and permitting the right side of the heart to function whereby oxygen-depleted blood returning through the systemic veins to the right atrium is directed through the right ventricle to the patient's lungs for oxygenation and subsequent pulmonary circulation.

Circulatory support system

An apparatus for servicing a removable RAM package of an ambulatory medical monitor is disclosed. The RAM package comprises a RAM for storing blood pressure data and operating parameters and a real time timer. Both are coupled to a multipin edge connector by parallel multibit data and address buses. An adapter for servicing the RAM package by a scanner controller through a standard serial interface is provided. The adapter comprises a microcomputer chip coupled between an RS-232 serial interface and a multipin edge connector for mating engagement with the edge connector on the RAM package. Servicing includes writing and reading data from the RAM package, and reading and setting the time in the real time timer. The apparatus further includes means for controlling access to the adapter by the scanner controller using an identification and unlocking scheme. The system will not unlock if a RAM package is not coupled to the adapter.
