摘要： The present technology relates to interatrial shunting systems and methods. In some embodiments, the present technology includes interatrial shunting systems that include a shunting element having a lumen extending therethrough that is configured to fluidly couple the left atrium and the right atrium when the shunting element is implanted in a patient. The system can also include an energy receiving component for receiving energy from an energy source positioned external to the body, an energy storage component for storing the received energy, and/or a flow control mechanism for adjusting a geometry of the lumen.

摘要： Disclosed herein is an inflow cannula for an implantable blood pump assembly. The inflow cannula includes a tubular body that extends from a proximal end to a distal end. The tubular body includes a proximal portion adapted for connection to a pump housing, and a distal portion adapted for positioning within an opening formed in a heart. The inflow cannula further includes an expandable sleeve coupled to an exterior surface of the distal portion. The sleeve has a first portion coupled to the distal portion of the tubular body, and a second portion extending from the distal end of the tubular body. The second portion is deployable from a first, stored configuration to a second, deployed configuration in which the second portion expands radially to engage and conform to an endocardial surface of the heart.

摘要： A blood circulation assist system includes a ventricular assist device (VAD) and a controller. The VAD is attachable to a heart of a patient to pump blood from a ventricle of the heart into a blood vessel of the patient. The VAD includes an impeller, a motor stator operable to rotate the impeller, and an accelerometer generating an accelerometer output indicative of accelerations of the VAD. The controller is configured to process the accelerometer output to generate patient monitoring data for the patient.

摘要： A kit including a sheath having a tubular body with proximal and distal ends, an axis extending between the ends and a wall defining a bore extending along the axis to the distal end of the body. A delivery tube having proximal and distal ends and a lumen is adapted for disposition within the bore of the sheath in sealing engagement with the sheath, the delivery tube being slideable distally relative to the sheath. An elongated cannula having proximal and distal ends and a lumen is adapted for disposition inside the lumen of the delivery tube and an elongated dilator is adapted to fit within the lumen of the cannula with a proximal portion of the dilator extending proximally beyond the proximal ends of the cannula and delivery tube and in sealing engagement with the delivery tube proximal to the cannula.

摘要： An intravascular blood pump having a drive section (11), a catheter (14) fastened to the drive section proximally and a pump section (12) fastened to the drive section distally possesses an electric motor (21) whose motor shaft (25) is mounted in the drive section (11) with two radial sliding bearings (27, 31) and an axial sliding bearing (40). During operation, purge fluid is conveyed through the bearing gap of the axial sliding bearing (40) and farther through the radial sliding bearing (31) at the distal end of the drive section (11). The purge fluid is highly viscous, for example 20% glucose solution.

摘要： The invention relates to a fluid pump device, in particular for the medical application, with a compressible pump housing and rotor, as well as with an actuation means which runs in the sleeve and on whose end the fluid pump is arranged. In order to utilize all possibilities of a space-saving arrangement of the respective pump housing of the rotor, which is compressible per se, and as the case may be, a bearing arrangement, the mentioned elements are displaceable to one another in the axial direction compared to an operation position. In particular these elements may be end-configured by way of an axial movement of the drive shaft after the assembly.
