Abstract: 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. 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 such as 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.

Abstract: The present disclosure 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 disclosure also relates to a method of using a blood pump system for persistently increasing the overall diameter and lumen diameter of peripheral veins and arteries by persistently increasing the speed of blood and the wall shear stress in a peripheral vein or artery for period of time sufficient to result in a persistent increase in the overall diameter and lumen diameter of the vessel.

Abstract: An end effector for use and connection to a robot arm of a robotic surgical system, wherein the end effector is controlled and/or articulated by at least one cable extending from a respective motor of a control device of the robot surgical system, is provided. The end effector includes a jaw assembly defining a longitudinal axis and including a pair of jaws. Each jaw includes a proximal portion pivotally connected to the distal hub assembly; and a distal portion extending distally of the proximal portion thereof. The end effector additionally includes an actuation cable having a distal end operatively connected to the pair of jaws and a proximal end operatively connected to the at least one motor. In use, axial translation of the actuation cable results in one of an opening and a closing of the jaw assembly.

Abstract: Tracheal tubes having an integrated calorimetric CO2 indicator are provided. In certain embodiment, the integrated CO2 indicator is selectively sealed from the remainder of the tracheal tube by a removable sterilization barrier. Also provided are CO2 indicators that exhibit long lasting, breath-to-breath dynamic color change and are storage stable. The devices and compositions of the invention find use in a variety of applications, e.g. in emergent intubation of a subject. Also provided are methods of making the devices and compositions, as well as kits that include the devices and/or compositions of the invention.
