A catheter apparatus can include a first magnet coupled to a catheter and a second magnet configured to couple to a patient's skin. When the catheter and the first magnet are positioned within a patient's body, the second magnet can exert a magnetic force on the first magnet that stabilizes the catheter relative to the second magnet. The second magnet can be directly attached to the patient's skin or secondary devices such as straps can be used to place the second magnet in a fixed position relative to the patient's body. In some implementations, a plurality of magnets can facilitate holding the catheter in a substantially fixed position within the patient.

Magnetic fixation apparatus for percutaneous catheter

A heart pump assembly includes an elongate catheter with a proximal portion and a distal portion, a rotor at the distal portion of the elongate catheter, a driveshaft, and a bearing. The rotor can include an impeller blade shaped to induce fluid flow in a first axial direction. The drive shaft may be coupled to or integrally formed with a proximal end of the rotor and can include a pump element formed in a surface of the drive shaft. The bearing can include a bore into which the drive shaft extends. The pump element is shaped so as to induce fluid flow through the bore in a second axial direction which can be the same or opposite to the first axial direction.

Heart pump with passive purge system

A flowpath wall is provided for bounding hot combustion gases in a gas turbine engine. The wall includes opposite outer and inner surfaces and a plurality of cooling holes extending therebetween. A thermal barrier coating is bonded to the outer surface and covers blind the holes thereat.
