A system for detecting whether a vascular access has been interrupted in an arrangement in which two catheters or needles are present in a blood vessel, fistula or graft. A fluid line leading to a pump is connected via a first connector to a first indwelling catheter, and a fluid line leading from a pump is connected via a second connector to a second indwelling catheter. Each connector is equipped with an electrode in contact with the lumen of the connector, the electrodes electrically connected to an electronic circuit that measures the impedance or conductivity of fluid between the first connector and second connectors via a fluid path through the blood vessel, fistula or graft. An electronic controller receives the impedance or conductivity data and processes the data to determine whether a vascular access disconnection has occurred. The processing may involve filtering the signal received by the controller, and/or setting provisional flags for a disconnection event that may be cleared if the signal changes before the expiration of a counter.

Systems and methods for detecting vascular access disconnection

A system and method for growing and maintaining biological material including producing a protein associated with the tissue, selecting cells associated with the tissue, expanding the cells, creating at least one tissue bio-ink including the expanded cells, printing the at least one tissue bio-ink in at least one tissue growth medium mixture, growing the tissue from the printed at least one tissue bio-ink, and maintaining viability of the tissue.

System and method for creating tissue

A force transmission system as part of a surgical system which may be configured to be a minimally invasive and/or computer assisted surgical system. Operation of the system may be controlled by transmission of a force from a first section to a second section of the system. The first section and the second section may be separated by a partition or a barrier. The first section may be a non-sterile section and the second section may be a sterile section of the surgical system.

Robotic surgery system, method, and apparatus

A valved manifold module is disclosed, constructed and arranged to be readily connected in a chain with similar modules to form a manifold assembly. The modular manifolds allows for expansion or modification of the manifold assembly to control a group of pneumatically or hydraulically driven pumps, valves or combinations thereof in a liquid flow control apparatus. The valved manifold module can be configured to accept a group of four substantially identical valve assemblies, and can be controlled by a local controller mounted to the manifold module, thus forming an independently programmable valved manifold module. The resulting modular system is expandable to allow for coordinated operations of a liquid flow control system, using substantially independent controller functions originating at the manifold assembly level.

Modular valve apparatus and system

A system for control of a device includes at least one sensor module detecting orientation of a user's body part. The at least one sensor module is in communication with a device module configured to command an associated device. The at least one sensor module detects orientation of the body part. The at least one sensor module sends output signals related to orientation of the user's body part to the device module and the device module controls the associated device based on the signals from the at least one sensor module.

System, method and apparatus for orientation control

Dialysis systems are disclosed comprising new fluid flow circuits. Systems may include blood and dialysate flow paths, where the dialysate flow path includes balancing, mixing, and/or directing circuits. Dialysate preparation may be decoupled from patient dialysis. Circuits may be defined within one or more cassettes. The fluid circuit fluid flow paths may be isolated from electrical components. A gas supply in fluid communication with the dialysate flow path and/or the dialyzer able to urge dialysate through the dialyzer and urge blood back to the patient may be included for certain emergency situations. Fluid handling devices, such as pumps, valves, and mixers that can be actuated using a control fluid may be included. Control fluid may be delivered by an external pump or other device, which may be detachable and/or generally rigid, optionally with a diaphragm dividing the device into first and second compartments.

Blood treatment systems and methods

A robotic assembly control system is disclosed. The robotic assembly control system includes an exoskeleton apparatus adapted to be worn by a user, at least one robotic assembly, the at least one robotic assembly controlled by the user by way of the exoskeleton, and at least one mobile platform, the at least one mobile platform controlled by the user and wherein the at least one robotic assembly is attached to the at least one mobile platform.

System and apparatus for robotic device and methods of using thereof

A syringe pump includes a lead screw, a motor, and a sliding block assembly. The lead screw has threads and the motor is coupled to the lead screw to rotate it. The half-nut housing has a half nut and a barrel cam. The half nut is disposed within the half-nut housing. The half nut has half-nut threads at an end adjacent to the lead screw void. The half nut engages or disengages with the threads of the lead screw. The half nut includes a half-nut cam-follower surface and a half nut slot. The barrel cam is disposed within the half-nut housing and engages with the half-nut cam-follower surface. The barrel cam includes a pin to fit within the half nut slot such that the barrel cam rotates between a first position and a second position to actuate the half nut between the engagement position and the disengagement position, respectively.

Syringe pump and related method

A syringe pump is disclosed that includes a pressure sensor assembly, a plunger, first and second pressure sensors, and a processor. The pressure sensor assembly senses a force and includes the plunger having a sensing surface configured to receive the force, the first pressure sensor operatively coupled to the plunger and configured to estimate the force applied to the sensing surface, and the second pressure sensor operatively coupled to the plunger and configured to estimate the force applied to the sensing surface. The processor is coupled to the first and second pressure sensors to estimate a magnitude of the force.

Syringe pump having a pressure sensor assembly

A pump for pumping fluid includes a tube platen, a plunger, a bias member, inlet and outlet valves, an actuator mechanism, a position sensor, and a processor. The plunger is configured for actuation toward and away from the infusion-tube when the tube platen is disposed opposite to the plunger. The tube platen can hold an intravenous infusion tube. The bias member is configured to urge the plunger toward the tube platen.

Apparatus for infusing fluid

A powered balancing mobility device that can provide the user the ability to safely navigate expected environments of daily living including the ability to maneuver in confined spaces and to climb curbs, stairs, and other obstacles, and to travel safely and comfortably in vehicles. The mobility device can provide elevated, balanced travel.

Mobility device

A system for powering a prosthetic arm is disclosed. The system includes at least one internal battery located in the prosthetic arm, at least one external battery connected to the prosthetic arm, and a master controller configured to connect either the at least one internal battery or the at least one external battery to a power bus to power the prosthetic arm.
