The present invention relates to an implantable infusion pump having a refillable infusate reservoir in fluid communication with a delivery site via a flow path. This flow path includes a flow resistance. The infusion pump includes a sensing device(s), positioned relative to the flow path, to provide data regarding a flow rate along the flow path. The infusion pump effects a division of a total flow period into at least a plurality of unit dose periods, each unit dose period effecting delivery of a unit dose of infusate. The cumulative effect of delivering the total number of unit dose periods is the delivery of a desired dose over the total flow period. The present invention permits a reservoir pressure to vary over any portion of total flow period but effects a constant-pressure state over each unit dose cycle.

A neuromodulation therapy system includes a programmer and a stimulation system. The stimulation system is capable of storing multiple data sets, each data set effecting an independent therapy. The stimulation system includes a display mechanism that can display certain imagery to distinguish visually one therapy from another therapy.

The present invention relates to an epidural stimulation lead having at least one electrode that substantially encircles another electrode. Operatively, the encircling electrode can be set as an, anode and the encircled electrode can be set as a cathode to generate an electrical field therebetween. The encircling electrode functions in this capacity as an anode guard, which among other things, concentrates the electrical field about the designated cathode and limits the lateral range of a generated electrical field.

The invention is directed to a dose control apparatus. The apparatus has two armatures pressed against a valve seat by at least one spring. A coil induces a magnetic field that motivates the armatures against the force of the spring, thereby opening the valve. The armatures may move along a common axis in opposite directions. The apparatus may also include a core located between the armatures and a casing about the coil. The core and casing act to guide the magnetic field, reducing the power requirements for creating the field. Current may be periodically reversed in the coil to provide a degaussing field. In addition, a signal may be produced by the coil in the presence an externally applied magnetic field such as an MRI. An opposing magnetic field may be produced by the coil or the current provided to the coil may be adjusted.

The present invention relates to a percutaneous insertion-capable lead, wherein insertion is made through a percutaneous insertion structure. For one embodiment of such lead, the electrode-supporting stimulation portion of the lead includes at lease one waisted region, relative to a transverse dimension of the lead, to facilitate lead steerability.

The invention is directed to a dose control apparatus for manipulating the dosage of one or more pharmaceutical solutions emanating from an implantable drug infusion pump. The dose control apparatus has a movable core that is held in a desired position by a magnet. The apparatus has at least one coil that, when activated, motivates the core to move to a new position. The core may be held in the second position by another magnet. The apparatus may have more that one coil provide various control options. In addition, the coils may be used to determine core position or the presence and strength of an externally applied magnetic field such as that produced in an MRI. The coils may also be used to produce a magnetic field counteracting the externally applied field or to produce a degaussing field.

The invention is directed to a method and circuitry for controlling dosage rates of a treatment solution. An electric pulse is directed through a coil, inducing a magnetic field and causing a valve to open. A subsequent set of pulses is directed through the coil to maintain the position of the valve. Between pulses, the coil motivates current to flow. Energy associated with the current is captured in a collection circuitry. The method and circuitry may also interpret a signal induced in the coil by an externally applied magnetic field such as that produced by an MIR. The method and circuitry may provide an electric signal to counteract the externally applied magnetic field or to produce a degaussing field.

An implantable, substantially isodiametric, low resistance implantable lead having at least one electrode positioned in a stimulation/sensing portion of the lead as well as a method of manufacturing the same. At least the stimulation/sensing portion is unitized through partially surrounding and supporting insulation and conductive element(s) of the stimulation/sensing portion with a fused matrix of material having mechanical properties consistent with a body of the lead.
