摘要： An intrathecal catheter for delivering fluid to, or withdrawing fluid from, the cerebrospinal fluid compartment of a patient, includes a proximal end and a distal portion. The distal portion has an outer diameter of about 1 mm or less, a bending stiffness of about 0.002 pounds per square inch or less, and a distal end. A delivery region is located between the proximal end and the distal end, and a lumen extends from the proximal end to the delivery region. The catheter may further include a coiled structure region to prevent dislodgement of the catheter from a tissue in which the coiled structure is implanted, for example the cisterna magna. The catheter may also include tines to anchor portions of the catheter, for example to a portion of the spinal canal.

摘要： The present invention is directed to methods and systems for the treatment of inborn genetic errors or other defects that cause deficiencies of active enzymes or proteins within the cells of the central nervous system. Such methods and systems generally comprise an implantable catheter system designed for the chronic delivery of specially formulated proteins to intrathecal, intracerebroventricular, and/or intraparenchymal regions of the central nervous system. The invention has application in the neuropathic aspects of the broad category of lysosomal storage diseases. These genetic based diseases are the result of insufficient enzyme activity to catabolize specific substances, which thereby accumulate in the cellular lysosomes.

摘要： A method for delivering a large molecule to the brain includes administering the large molecule via an intermittent bolus regimen intrathecally to a subject at a level of C3 or above. A method for delivering a large molecule to the brain includes rostrally advancing a catheter in the intrathecal space of a subject until a delivery region of the catheter is located at a level of C3 or above and delivering the large molecule via the delivery region. Employing aspects of such methods, a method for altering eating behavior is described.

摘要： Methods for delivering first and second fluid compositions to a target location of a subject include delivering the first composition from reservoir of an implantable infusion pump and delivering the second composition through a catheter access port of the implantable infusion device. The access port and reservoir are fluidly coupled to a catheter having a delivery region implanted in the target region. The methods more fully realize the therapeutic potential of infusion devices having both an access port and a reservoir. Strategic use of different agents that compliment the function of each other delivered via either the access port or the reservoir can result in enhanced therapeutic potential.

摘要： A lead and a lead system for dispersion of a cardioversion/defibrillation electrode formed of one or more small diameter defibrillation electrodes in a heart chamber and for attaching a pace/sense electrode in contact with the heart. The small diameter defibrillation electrode or electrodes extend distally from the distal end of the lead body. If multiple electrodes are employed, they are preferably biased to spread apart when unrestrained and have a cross-section size small enough to be inserted into interstices of trabeculae in the ventricular chamber. The distal ends of the defibrillation electrodes may be free of attachment to the lead body or may be attached by a weak bond to the distal portion of the lead.

摘要： A method of improving the breakdown strength of polymer multi-layer (PML) capacitors is provided. The method comprises removing metal, specifically, aluminum, from the cut edge. This is done by either etching back the metal electrode layers in either basic or acidic solution or by anodizing the metal to cover that portion of the metal at the edge with an oxide. Removing the metal from the cut edge increases the breakdown strength of the PML capacitors by a factor of two or more.
