Abstract: A low profile wearable infusion device comprises a generally cylindrical reservoir having a diameter greater than its height and a drive that causes a piston to move an incremental distance within the reservoir to cause the device to dispense a dose of medicament.

Abstract: A wearable infusion device comprises a component that causes a piston to move an incremental distance to cause the device to dispense a dose of medicament from a reservoir.

Abstract: Systems and methods for delivering medication to a patient are disclosed. The system has a reservoir, a sequencer/monitor, and an insertion set which are mated during use.

Abstract: Systems and methods for storing and dispensing a fluid on-demand includes a reservoir; an energy storage device coupled to the reservoir to store energy, wherein the energy is mechanically generated by a user's action; a cannula assembly adapted to be positioned on a patient and coupled to the reservoir prior to use; and a sequencer coupled to the reservoir and the energy storage device to allow the fluid to be dispensed upon command.

Abstract: A method treats a patient for adult-onset dementia of the Alzheimer's type by removing a portion of the patient's cerebrospinal fluid, preferably (although not necessarily) by transporting the fluid to another portion of the patient's body. An apparatus for removing cerebrospinal fluid includes (1) a conduit with a first opening and a second opening, the first opening of the conduit being disposed in fluid communication with a space within a patient's subarachnoid space, the second opening being disposed in fluid communication with another portion of the patient's body; and (2) a flow rate control device attached to the conduit.

Abstract: Devices and methods for removing cerebrospinal fluid (CSF) from a CSF space of a patient at relatively constant flow rates for patients having normal intracranial pressures, e.g. patients not suffering from hydrocephalus. The devices and methods provide drainage paths which permit the removal of CSF at relatively low flow rates, usually below, 0.2 ml/min, at normal intracranial pressures, e.g. an intracranial pressure between ?170 mm of H2O in upright patients and 200 mm of H2O in reclining patients. The removal of CSF at relatively low, constant rates is particularly suitable for treating Alzheimer's disease and other conditions related to the presence of toxic and/or pathogenic substances in the CSF.

Abstract: Devices and methods for removing cerebrospinal fluid (CSF) from a CSF space of a patient at relatively constant flow rates for patients having normal intracranial pressures, e.g. patients not suffering from hydrocephalus. The devices and methods provide drainage paths which permit the removal of CSF at relatively low flow rates, usually below 0.2 ml/min, at normal intracranial pressures, e.g. an intracranial pressure between −170 mm of H2O in upright patients and 200 mm of H2O in reclining patients. The removal of CSF at relatively low, constant rates is particularly suitable for treating Alzheimer's disease and other conditions related to the presence of toxic and/or pathogenic substances in the CSF.

Abstract: Apparatus and methods for removing cerebral spinal fluid (CSF) from a CSF space of a patient at constant volumetric rates rely on the intermittent timed or controlled opening of on-off and other control valves. When using valves, the volume of fluid drained may be measured to time the opening and closing of the valves. Alternatively, the valves can be used to control into and/or out of an accumulator, where the accumulator is drained on a periodic timed basis to achieve constant drainage over a one day or other predetermined time period. Such controlled flow volumes may also be achieved using positive displacement pumps which are operated for predetermined time intervals during each one day or other predetermined time period.
