A minimally invasive system for a wireless circulatory support pump that utilizes a low profile catheter-based techniques and provides temporary and chronic circulatory support depending on the needs of the subject. The system includes a wireless circulatory assist pump, a deployment catheter, and a retrieval catheter for inserting and removing the wireless circulatory assist pump from a subject. The wireless circulatory support pump is relatively easy to place, has high flow rates, and provide improvements in the subject's renal function.

A connector for a medical device. The connector including an elongate body having a proximal end and a distal end. The connector further including a strut, a plurality of conductors, and a plurality of electrical contacts. The strut being disposed within the elongate body and defining a plurality of channels. Each of the plurality of channels having a proximal end and a distal end opposite the proximal end. The plurality of conductors being disposed within the elongate body and are sized and configured to be received within the plurality of channels and extend between the proximal end and the distal end. The plurality of electrical contacts being coupled to an outer surface of the elongate body and in communication with the plurality of conductors.

A header for a controller for an implantable medical device. The header includes at least one bore sized and configured to receive a corresponding connector for the implantable medical device. At least one elongate thermally conducting element is disposed within the header and proximate the at least one bore, the at least one elongate thermally conducting element being configured to conduct heat away from the at least one bore and spread heat within the header when the corresponding connector is received within the at least one bore and is communication with the implantable medical device.

A coupling for a circulatory assist device includes a first coupler and a second coupler. The first coupler including a first inner portion configured to be secured to a first shaft, a first body extending from the inner portion, and first magnets joined to the body. The second coupler offset from and separate from the first coupler with a gap therebetween. The second coupler including a second inner portion configured to be secured to a second shaft, a second body extending from the second inner portion, and second magnets joined to the body. The second magnets magnetically coupled to the first magnets and configured to transfer a torque applied to one of the first shaft and the second shaft to an other of the first shaft and the second shaft.

Mechanical circulatory supports configured to operate in series with the native heart are disclosed. In an embodiment, an intravascular propeller is installed into the descending aorta and anchored within via an expandable anchoring mechanism. The propeller and anchoring mechanism may be foldable so as to be percutaneously deliverable to the aorta. The propeller may have foldable blades. The blades may be magnetic and may be driven by a concentric electromagnetic stator circumferentially outside the magnetic blades. The stator may be intravascular or may be configured to be installed around the outer circumference of the blood vessel. The support may create a pressure rise between about 20-50 mmHg, and maintain a flow rate of about 5 L/min. The support may have one or more pairs of contra-rotating propellers to modulate the tangential velocity of the blood flow. The support may have static pre-swirlers and or de-swirlers. The support may be optimized to replicate naturally occurring vortex formation within the descending aorta.
