Abstract: A plug for coupling to a suture ring may include a distal portion extending from a distal end toward a proximal end of the plug, and a proximal portion coupled to the distal portion and extending from the proximal end toward the distal end of the plug. The distal portion may include a distal cylindrical body centered on a central axis of the plug and configured for being received at least partially within a central opening of the suture ring, and the distal cylindrical body may have a first outer diameter. The proximal portion may include a proximal cylindrical body centered on the central axis of the plug and configured for extending over a proximal end of the suture ring when the distal cylindrical body is received at least partially within the central opening of the suture ring, and the proximal cylindrical body may have a second outer diameter that is greater than the first outer diameter.

Abstract: A percutaneous circulatory support system includes an impeller and a motor operably coupled to the impeller. A controller is operably coupled to the motor, and the controller is configured to: drive the motor, the motor thereby rotating the impeller to cause blood to flow; determine that an operating parameter of the system deviates from a symmetric waveform; and in response to determining that the operating parameter deviates from the symmetric waveform, provide an alert of aortic valve insufficiency.

Abstract: A cardiac assist system includes a pneumatic effector which is implanted beneath a pericardial sac and over a myocardial surface overlying the patient's left ventricle. A port is implanted and receives a percutaneously introduced cannula. The port is connected to supply a driving gas received from the cannula to the pneumatic effector. An external drive unit includes a pump assembly and control circuitry which operate the pump to actuate the pneumatic effector in response to the patient's sensed heart rhythm. A connecting tube has a pump end connected to the pump and a percutaneous port-connecting end attached to the implantable port.

Abstract: The invention relates to a feed line (105) for a pump unit (110) of a cardiac support system (100). The feed line (105) is embodied to guide a fluid flow to a pump unit (110) of the cardiac support system (100). The feed line (105) comprises a feed head portion (130) with at least one introduction opening (140) for introducing the fluid flow into the feed line (105) and a contoured portion (135) with an inner surface contour. The contoured portion (135) is disposed adjacent to the feed head portion (130). An inner diameter of the contoured portion (135) at a first position is greater than the inner diameter at a second position. The inner surface contour has a rounded portion at the second position for reducing the inner diameter.

Abstract: A rotary pump housing having a cylindrical bore, a pumping chamber and a motor stator including an electrically conductive coil located within the housing and surrounding a portion of the cylindrical bore. A rotor has a cylindrical shaft with an impeller and one or of magnets located within the shaft that are responsive to the motor stator to drive actuation of the rotor. The housing bore is closely fitted to the outer surface of the shaft forming a hydrodynamic journal bearing with an annular clearance defining a leakage flow path. One or more of radial or axial thrust bearings may be provided to provide rotation stability to the rotor and flow within the leakage flow path. The relative orientation of positions of the inflow, outflow, and leakage flow paths may be varied within the pump, such as to accommodate different intended methods for implantation and/or use.

A delivery tube passes through the subject's aorta, from outside the subject into the left ventricle. The delivery tube includes an outer layer that varies along a length of the delivery tube such that a flexural rigidity of the delivery tube at a first portion of the delivery tube, which is configured to traverse the aortic valve, is less than the flexural rigidity at a second portion, which is configured to traverse at least a portion of the aortic arch, and the flexural rigidity at the second portion is less than the flexural rigidity at a third portion, which is configured to traverse the descending aorta. Other applications are also described.
