摘要:
The present invention provides a minimally-invasive percutaneous device that can be positioned within the body of a subject to aid in the movement or pumping of a bodily fluid. In one embodiment, the device comprises a plurality of pump units configured to transform from a first compressed configuration where the pump units are organized in a serial arrangement into a second expanded configuration where the pump units are reorganized into a parallel arrangement.

The present invention relates to systems and methods for in situ inspection, interrogation, and maintenance of heart pump function in subjects with an implanted heart pump. In certain embodiments, the system comprises a catheter assembly deliverable to the inflow port and outflow port of the implanted heart pump. The system comprises additional components used to examine pump function and prevent malfunction. In certain embodiments, the invention allows for temporary, mid-term, or permanent exclusion of the implanted heart pump from cardiac function without surgically removing the pump.

The present invention provides ventricular restoration devices and snare devices as part of a papillary muscle approximation and ventricular restoration (PAP-VR) system and methods for using the same to repair mitral regurgitation (MR). The ventricular restoration devices include two collapsible anchors positioned at opposing ends of a collapsible stent, wherein the devices are threaded through a subject's anatomy such that the anchors rest outside of tissue and are held taut by the stent inbetween. The snare devices comprise an out-of-plane curved construction to navigate magnetized trapping lines around difficult to reach anatomy to lasso and tighten anatomical structures.

A heart failure recovery device includes a fluid pump having an inlet and an outlet in fluid communication with a pump reservoir, and a pumping element disposed within the pump reservoir, the pumping element including a protrusion that in an active state is configured to rotate and move fluid away from the inlet and towards the outlet. A receiver coil can be electrically coupled to the fluid pump and is configured to subcutaneously absorb electromagnetic energy for powering the fluid pump. In certain embodiments, an implantable port provides fluid access to the pump reservoir for cleaning and maintaining the fluid pump. In other embodiments, a valve closes fluid access to at least one of the inlet and the outlet during periods when the device is not being used for treatment.

The present invention provides intracardiac devices and methods of implanting the same. The intracardiac devices have a collapsible stent design and include an axial pump to support cardiac function. The axial pump can feature a shaftless fluid actuator for enhanced efficiency in fluid transfer while reducing blood cell trauma. The intracardiac devices include valves that are closeable to seal implanted devices from a subject's anatomy. The intracardiac devices include a cleaning system configured to introduce and circulate cleaning solutions and therapeutics to implanted devices. The intracardiac devices are wirelessly powered and controlled. The intracardiac devices can be implanted using minimally invasive procedures without the need for open heart surgery.

A system for treating aortic dissection includes a sinotubular junction magnetic array having a first plurality of magnetic elements, a counter-magnetic array having a second plurality of magnetic elements, and an ascending aortic stent graft comprising a third plurality of magnetic elements. A method for treating aortic dissection includes the steps of positioning a sinotubular junction magnetic array at the sinotubular junction, advancing counter magnetic constructs from the femoral vein and positioning them in the right atrium, expanding the sinotubular junction ring at a target position, advancing the counter magnetic array to form an at least partial circumferential seal, and advancing and positioning an ascending magnetic graft within an interior of the sinotubular junction magnetic array. A system for treating aortic dissection, a fixation device for anchoring an ascending aortic stent graft, and a transcatheter device for treating aortic dissection are also described.
