A multi-disk spinning disk assembly for atomization and encapsulation applications. A number of disksand spacers () are stacked to form a disk stackhaving a feed wellin the center core of the stack. The fluid to be atomized or encapsulated is delivered to the feed well. The fluid then flows into spacer channels () within or on the surface of the spacers. The channels () communicate the fluid toward the outer edges of the disks. The disk surface past the spacers () can have various configurations, such as teeth, weirs, or a bigger or smaller diameter, as desired for particular atomization or encapsulation characteristics.

Multi-disk spinning disk assembly for atomization and encapsulation

A multi-disk spinning disk assembly for atomization and encapsulation applications. A number of patterned disks are stacked to form a disk stack having a feed well in the center core of the stack. Each patterned disk has channels defined by spacers, with the channels and spacers being of varying depths, heights, and/or widths. The fluid to be atomized or encapsulated is delivered to the feed well. The fluid then flows into the channels, which communicate the fluid toward the outer edges of the disks. The fluid exits the disk stack from a circumferential gap, which is created by interposing spacing disks between the patterned disks.

An access disconnection system includes an extracorporeal circuit; first and second contacts provided in the extracorporeal circuit; a current source communicating with the first contact and configured to generate a current within fluid flowing through the extracorporeal circuit; and an apparatus positioned to apply a signal at multiple points along a path from the extracorporeal circuit, the signals tending to prevent at least a portion of the current from traveling through a ground path in parallel to the extracorporeal circuit.

Enhanced signal detection for access disconnection systems

In general, various embodiments of the present invention comprise an external fixation device, an internal fixation device, and a lower extremity stabilizer. The external fixation device is connected to the lower extremity stabilizer and the external fixation device is adjustably connected to the internal fixation device. The internal fixation device is capable of being attached to at least one bone in a patient's foot, ankle, and/or lower extremity. The system is capable of simultaneously compressing and stabilizing at least one bone for treating Charcot neuroarthropathy, fractures, revisional foot and ankle surgery including but not limited to malunions, nonunions, delayed unions, fibrous unions, avascular necrosis, resected osteomyelitis, incorporated autogenous and/or allogenic bone grafts for arthrodesis procedures, pseudoarthrosis and bones with decreased mineral density and cortical stiffness, and/or the like for any reconstructive and/or elective foot and ankle surgery where a compression arthrodesis is needed. The external fixation device and/or lower extremity stabilizer can be removed after a certain period of time, leaving the internal fixation system within the body for prolonged stabilization and maintenance of the arthrodesis site(s).

Foot, ankle and lower extremity compression and fixation system and related uses

A coupler includes a conductive polymer material that is so constructed and arranged to join tubing, wherein the conductive polymer material includes a conductive polymer component selected from the group consisting of polyaniline, polypyrrole, polythiophenes, polyethylenedioxythiophene, poly(p-phenylene vinylene) and mixtures thereof.

Conductive polymer materials and applications thereof including monitoring and providing effective therapy

The present devices, systems and processes can simultaneously reduce a malady of the foot, ankle, and/or lower extremity and provide compression and stabilization through the use of a combined internal fixation device, external fixation device and a lower extremity stabilizing device. The various embodiments of the system are capable of providing adequate compression in the medial, central and/or lateral columns and/or sides of the foot, ankle, and/or lower extremity, as well as treating Charcot neuroarthropathy, fractures, revisional foot and combination of ankle surgeries. The external fixation device and/or lower extremity stabilizer can be removed after a certain period of time, leaving the internal fixation system within the body for prolonged stabilization and maintenance of the arthrodesis site(s).

An access disconnection method for a machine employing a blood circuit, the blood circuit having a machine segment and a patient access segment, the method comprising: injecting an electrical signal into the blood circuit between the machine segment and the patient access segment; attempting to cause the electrical signal to flow through only the patient access segment and to bypass the machine segment; and measuring the signal in the patient access segment and determining that an access disconnection event has occurred upon a threshold change in the measured signal.

Systems and methods for dialysis access disconnection

Apparatuses, devices, systems and methods for detecting access disconnection are provided. In one embodiment, a medical fluid system includes (i) a medical fluid machine and (ii) a device operable with the medical fluid machine, the device configured to provide electrical contact with a medical fluid, the device including (a) a tube used during dialysis therapy through which the medical fluid can flow, and (b) a conductive element configured to self-sealingly pierce the tube, the conductive element having a first portion exposed to the medical fluid and a second portion external to the tube.

Access disconnection systems and methods

Apparatuses, devices, systems and methods for detecting access disconnection are provided. The present invention includes electrical contacts in fluid and electrical communication with a fluid passing between a patient and a medical system during therapy. In this regard, the present invention can use a direct-contact measurement to detect access disconnection, such as dislodgment of an access device from the patient through which fluid can flow during therapy including, for example, medication delivery, dialysis therapy and the like.
