The embodiments provide a method for treating an intervertebral disc having a nucleus pulposus and an annulus fibrosis, using one or more superabsorbent polymers. Additionally, the embodiments provide a method for bulking up an intervertebral disc having a nucleus pulposus and an annulus fibrosis, using one or more superabsorbent polymers. The methods comprise introducing an amount of the superabsorbent polymers into the intervertebral disc space without removing nucleus pulposus or annulus fibrosis material.

A method of seating a fluid reservoir in a housing of a fluid infusion device is presented here. The method is performed prior to establishing an outgoing fluid flow path from the fluid reservoir. The method begins by detecting insertion of the fluid reservoir into the housing of the fluid infusion device. In response to detecting the insertion, the method determines whether the fluid reservoir is in need of depressurization. When the fluid reservoir is in need of depressurization, the drive motor assembly of the fluid infusion device is rewound to depressurize the fluid reservoir. After depressurizing the fluid reservoir, an equalization state for the fluid reservoir is achieved. After achieving the equilibrium state, the drive motor assembly is advanced to obtain an initial seated state for the fluid reservoir.

Methods of treating glaucoma are disclosed, such as a method that includes inserting a stent through an incision in an eye; the stent having an inflow portion that is in fluid communication with an outflow portion of the stent; transporting the stent from the incision through the anterior chamber of the eye to an aqueous cavity of the eye, such that the inflow portion of the stent is positioned in the anterior chamber and the outflow portion of the stent is positioned at the aqueous cavity; and infusing fluid from the inflow portion to the outflow portion of the stent.

An apparatus and method are provided to verify the composition of a medical fluid in a fluid infusion channel by comparison with clinician-entered input. Light is transmitted through the channel and detected by a sensor that generates signals representative of the spectral data of the light detected. A processor compares the spectral data of the light detected to the spectral data associated with the expected contents of the channel to verify that the correct fluid is being infused.

A patient hydration system including an infusion device for administering hydration fluid to a patient, and a hydration fluid measurement device responsive to a source of hydration fluid, a patient urine output measurement device. A controller is responsive to the hydration fluid measurement device and the patient urine output measurement device. The controller operates the infusion device, in response to the patient urine output measurement device and the hydration fluid measurement device, to hydrate the patient based on the patient's urine output. The controller also monitors the operation history of the infusion device thereby providing redundancy in the measurement of the amount of hydration fluid administered to the patient.

A fluid infusion device and a method of using the same. The device includes an outer, flexible guide catheter having a distal end for introduction beneath the skull of a patient and a proximal end remaining external of the patient. A flexible infusion fiber is located within the guide catheter and has a distal end extending outwardly from the guide catheter to be located in a target area within the patient's brain. The infusion fiber can be fixed or axially movable within the guide catheter. In the latter embodiment, the proximal end of the infusion fiber extending outwardly from the guide catheter can be manipulated to locate the distal end of the infusion fiber in the target area. An infusion pump is connected to the proximal end of the infusion fiber to infuse a minute quantity of fluid at an extremely low flow rate into the brain of the patient.

A System manages IV pumps so that clinicians automatically receive alerts, decisions, and actions required to maintain a patient IV medication therapy according to a prescribed treatment protocol. An infusion pump monitoring system, includes an acquisition processor for acquiring fluid infusion parameters comprising a patient identifier, infusion fluid identifier and a rate of fluid infusion, for administration of an infusion fluid to a patient at a point of care using an infusion pump. The system also includes a repository of patient medical record information. A fluid infusion monitor uses acquired fluid infusion parameters for automatically searching a patient medical record in the repository for information concerning rate of fluid infusion of a particular infusion fluid and determining if a rate of a previously administered dose of the particular infusion fluid was lower than a rate indicated in the fluid infusion parameters. An interface processor automatically initiates generation of a message indicating a potential adverse reaction to the particular infusion fluid in response to a determination of a lower rate being employed for previously administering the particular infusion fluid.
