METHOD FOR SETTING UP A FLUID PROCESSING MEDICAL APPARATUS
A method for setting-up a fluid processing medical apparatus, the method includes: a) positioning a disposable component intended to be used for therapy with the fluid processing medical apparatus relative to a reader unit by a user; b) reading component related information provided on the disposable component by the reader unit; c) matching the read component related information with component related data stored in a database; and d) providing a selection of suitable therapies for the disposable component to the user based on the matching.
MANAGING PUMP SPEED WHEN POWER CONSTRAINED IN A FULLY IMPLANTED LVAD SYSTEM
A method of managing a speed of implantable blood pump. The implantable blood pump is in communication with an internal battery and a transcutaneous energy transfer system (TETS). The method includes starting the pump at a programmed set speed. The speed of the pump is decreased from the programmed set speed to a minimum set speed if either a capacity of the internal battery is less than a predetermined reserve level and TETS power is unavailable, or there is insufficient TETS power to maintain the programmed set speed. The speed of the pump is progressively decreased from the programmed set speed if there is insufficient power to maintain the programmed set speed.
Axial flow blood pump
An axial flow blood pump having a rotor rotatably mounted in a housing. The rotor includes at least two rotor blades having different configurations.
MEDICAL RESERVOIR LEVEL SENSOR
Devices can be used to detect a level of a fluid in a medical fluid reservoir. Methods for controlling the flow rate of a medical pump, and/or the occlusion amount of a medical fluid tube, that are based on the detected level of fluid in the medical reservoir can be used in a clinical setting.
Reduced rotational mass motor assembly for catheter pump
A catheter pump is disclosed. The catheter pump can include an impeller and a catheter body having a lumen in which waste fluid flows proximally therethrough during operation of the catheter pump. The catheter pump can also include a drive shaft disposed inside the catheter body. A motor assembly can include a chamber. The motor assembly can include a rotor disposed in the at least a portion of the chamber, the rotor mechanically coupled with a proximal portion of the drive shaft such that rotation of the rotor causes the drive shaft to rotate, the rotor including a longitudinal rotor lumen therethrough. The motor assembly can also comprise a stator assembly disposed about the rotor. During operation of the catheter pump, the waste fluid flows from the lumen into the chamber such that at least a portion of the waste fluid flows proximally through the longitudinal rotor lumen.
BLOOD PUMP SYSTEMS AND METHODS
The present invention relates to a rotary blood pump with a double pivot contact bearing system with an operating range between about 50 mL/min and about 1500 mL/min, wherein the force on the upper bearing is less than 3N during operating speeds up to 6000 rpm. The rotary blood pump is part of a blood pump system that includes blood conduit(s), a control system with optional sensors, and a power source. Embodiments of the present invention may include elements designed to increase the length of time the rotary blood system can operate effectively in vivo, including wear resistant bearing materials, a rotor back plate for magnetic attraction of the rotor to reduce bearing pivot bearing forces and wear, a rotor size and shape and a bearing gap that combine to create a hydrodynamic bearing effect and reduce bearing pivot bearing forces and wear, improved intravascular conduits with increased resistance to thrombosis, conduit insertion site cuffs to resist infection, and conduit side ports amenable to the easy insertion of guidewire and catheter-based medical devices to treat conduits and related blood vessels to maintain blood pump system function over time.
SYSTEMS AND METHODS FOR REDUCING PRESSURE AT AN OUTFLOW OF A DUCT
Various systems and methods are provided for reducing pressure at an outflow of a duct such as the thoracic duct or the lymphatic duct. In one embodiment, an indwelling catheter can be configured to be at least partially implanted within a vein of a patient in the vicinity of an outflow port of a duct of the lymphatic system. The catheter can include first and second restrictors each configured to at least partially occlude the vein within which the catheter is implanted and thus to restrict fluid flow within the vein when the restrictors are activated. The restrictors can each be configured to move between an activated configuration, in which the restrictor occludes the vein, and a relaxed configuration, in which the restrictor does not occlude the vein. The catheter can include a pump, such as an axial motor pump, configured to pump fluid through the catheter.
SYSTEM AND METHOD FOR CONTROLLING A CARDIAC ASSISTANCE SYSTEM
The invention relates to a system (100) and a method (500) for controlling a cardiac support system (10), comprising a first extracorporeal control device (110), wherein the first control device (110) is or can be connected to the cardiac support system (10) with a wire or a first coil (150) for communication and/or energy transfer, and comprising a second extracorporeal control device (120) which is wirelessly connected to the first control device (110). The invention also relates to a cardiac support system (10) having a control system according to the invention (100).
CARRYING CASE FOR CONTROLLER OF PATIENTS WITH VADS
