Abstract: A transcatheter blood pump implantable within a subject's lumen defined by a subject's lumen wall. The transcatheter blood pump includes an impeller having an axis of rotation, a shroud having a first shroud end portion, a second shroud end portion, and a shroud internal passage extending between the first shroud end portion and the second shroud end portion, the impeller disposed within the shroud internal passage, an electric motor configured to rotate the impeller, the electric motor having a first motor end portion and a second motor end portion, the first motor end portion coupled to the second shroud end portion, and an electric driveline configured to transmit operating power to the electric motor to rotate the impeller. The electric driveline extends along at least one of the shroud and the electric motor and is coupled thereto.

Abstract: Embodiments described herein include a modular transcatheterly implantable medical device. The medical device includes a plurality of assemblable blood pumps. Each one of the blood pumps includes a pump unit and an electrical wire configured for the pump unit to be electrically operated through the electrical wire. The medical device also includes an anchor having a first end portion and a second end portion, and the anchor is configured to intraluminally assemble to and intraluminally unassemble from the blood pumps. The medical device also includes a catheter. The catheter is configured to be in a slidable relationship with each one of the electrical wires for intraluminally assembling the blood pumps to the anchor and for intraluminally unassembling the blood pumps from the anchor. The medical device further includes a flexible linker configured to couple the catheter and the anchor.

Abstract: An implantable medical device includes a functional unit, an introducer unit for introducing and/or navigating the functional unit in a lumen of body conduit(s) of a subject, and an elongated operable element connectable to a controller for operating the functional unit though the elongated operable element in a lumen of body conduit(s) of the subject. The functional unit, introducer unit, and elongated operable element may be in a slidable relationship for assembling and unassembling the implantable medical device in vivo. The implantable medical device is implantable, explantable, and operable in a lumen of body conduit(s) of a subject according to related methods.

Abstract: System for assisting vascular fluid flow body comprising: Fluid pump having an inlet for fluid in the vascular system to enter and an outlet for discharging pumped fluid into the vascular system at a fluid pump outlet pressure. Occluder placed into the vascular system at a location downstream of the outlet of the fluid pump. Occluder having a configuration in which the occluder occludes the vascular system and a configuration in which pumped is capable of flowing past the occluder. In use, the occluder being actuatable to alternate between the occluded configuration, in which pumped fluid accumulates in the vascular system becoming increasingly under pressure via elastic deformation of vessels, and the flow configuration, in which accumulated pumped fluid under pressure flows past the occluder at a greater pressure than the fluid pump outlet pressure, returning the elastically deformed vessels towards their original state.
