An intra-aortic balloon pump (IABP) is provided that has a series of spiral pleats that function to control the wash of blood associated with an inflation cycle. Additionally, the torsional expansionincreases the net efficiency of the IABP relative to a conventional cylindrically shaped balloon. The inflating membrane is textured to promote natural growth of a biologic lining on the surface of the indwelling pump to reduce the need for anticoagulation and the risk of thromboembolic events; promote washing of the surface to minimize stasis and thrombus formation; minimize strain on the IABP; minimize elongation radially and longitudinally to avoid fatigue of the IABP; minimize stretching and stress distribution along a balloon; promote a sweeping effect through the channels in the non-expanded state to wash the surface; or a combination thereof.

An electric balloon pressure pump, which relates to a medical instrument. The electric balloon pressure pump comprises: a motor (3), a push rod (5) provided with an external thread; a push rod sleeve (7); and a control device, provided with an internal thread. One end of the push rod is fixedly mounted to the motor, and the other end of the push rod is a free end and extends into the push rod sleeve. The control device provided with an internal thread is fixedly mounted on the push rod sleeve. The push rod and the control device provided with an internal thread form a spirally connected fit. The motor drives the push rod, so that the push rod can go forwards and backwards in the push rod sleeve along the axial direction of the push rod sleeve. According to the pump, during the pressurization, the pressurization is implemented by means of the motor, thereby bringing labor saving and high efficiency. During the pressure relief, the rotatable fit of the push rod is removed by means of a pressure relief device, thereby allowing the push rod to directly move back. By controlling the running of the motor, linear pressurization, secondary curve pressurization and segmental pressurization can be performed, and data can be stored, shared and rechecked.
