摘要:
A device and method consisting of conductive, non-conductive, and support materials. These materials when dispensed or extruded onto a multitude of temporary structures will create an implantable conductive and non-conductive structure suitable for neurological electrical stimulation and neurological electrical recording. This structure may also be suitable for delivering fluid and/or contain optical structures suitable for physiological sensing.

The present invention relates to a percutaneous insertion-capable lead, wherein insertion made through a percutaneous insertion structure. For one embodiment of such lead, the electrode-supporting stimulation portion of the lead includes at least one waisted region, relative to a transverse dimension of the lead, to facilitate lead steerability.
摘要:
A torque wrench comprising a shaft, a shaft cam configured to rotate with the shaft around the longitudinal axis, a groove defined in the shaft cam, a ramp positioned within the groove at a position below the groove upper surface, an outer cam comprising an engaging member configured to selectively contact a ramp upper surface or groove upper surface. The wrench also comprises a spring to apply a downward force on the outer cam and a void defined in the groove between the ramp and a side wall of the groove to allow the engaging member to escape the groove when not contrained by the ramp.

Disclosed are systems and methods which provide a header assembly for interfacing a medical device with a lead, wherein the header assembly includes a strain relief portion integral thereto. The strain relief portion may be adapted to facilitate a user visually verifying when a lead has been fully inserted into the header. Structure, such as a band or ring, may be provided upon the strain relief portion in order to provide a readily identifiable visual aid for determining when a lead is fully inserted.
摘要:
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.

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.
