摘要： A needle and needle system that aids in determining needle position with respect to an implanted device. The system determines needle position by detecting changes in electrical characteristics and the system further may generate a cue to indicate proper needle placement within an implanted device. Methods for detecting needle position with respect to an implanted infusion device are also disclosed.

摘要： A method for adjusting delivery of a therapeutic fluid to a patient suffering from or at risk of pulmonary arterial hypertension includes introducing the therapeutic fluid to a patient via a catheter at a predetermined rate. The catheter is positioned to deliver the fluid to the right ventricle or the pulmonary artery. The catheter a one-way valve configured to allow the fluid to flow from the catheter to the target location. The method further includes monitoring pressure of the target location by monitoring internal catheter pressure, and adjusting the rate at which the therapeutic fluid is introduced to the catheter based on the monitored pressure. The rate at which the fluid is introduced to the catheter is increased if internal catheter pressure increases, and the rate at which the fluid is introduced to the catheter is decreased if the internal catheter pressure decreases.

摘要： A catheter system and method for intracranial infusion of therapeutic substances to a patient. An anchor formed of generally flexible, elastomeric material is used to mount the catheter to the outer surface of the skull of the patient. The anchor has a through hole for receiving the catheter, a channel, extending substantially from the through hole, into which a portion of the catheter may be inserted to retain the portion substantially parallel to the surface of the skull, and at least one flange for engaging the outer surface of the skull. An anchor clip may be provided to engage the anchor adjacent the through hole to further stabilize the catheter.

摘要： A medical electrical lead system featuring a medical electrical lead which features an improved anchoring sleeve. The medical electrical lead and anchoring sleeve cooperate with an introducer sheath to minimize the flow of blood through the introducer sheath during the introduction of the lead into the blood vessel. Specifically, the lead has a connector assembly, a conductor attached thereto and an electrode electrically coupled to the conductor. An insulative sleeve covers the conductor and an annular anchoring sleeve is movably positioned over the insulative sleeve. The anchoring sleeve has a distal end and a proximal end and further has an annular or circumferential seal within the inner lumen at the distal end. The distal end is further tapered along its exterior portion. The taper of the distal end cooperates with an introducer sheath to provide a seal between the outer portion of the anchoring sleeve and the introducer sheath. The circumferential seal on the same distal end cooperates with the medical electrical lead to create a seal between the anchoring sleeve and the medical electrical lead. In such a manner, a hemostatic seal is accomplished such that blood will not flow through the introducer sheath while the lead is within the introducer sheath and being positioned into the body.
