摘要： An implantable lead includes a lead body, having a distal end and a proximal end, configured to be implanted in a patient. An electrode assembly is provided at the distal end of the lead body, wherein the electrode assembly includes an electrode that is configured to deliver stimulating pulses. The electrode extends between a base and a tip at a distal end of the electrode. A shielding member is provided on the electrode assembly and is positioned to cover at least a portion of the electrode to electrically shield the electrode from RF fields. Optionally, the shielding member may include a shielding conductor that wraps about and extends longitudinally along a length of the electrode from the base to the tip. The shielding conductor may extend from the proximal end of the lead body at least to the distal end of the lead body.

摘要： An implantable lead assembly includes an elongated body, a bobbin, and a conductor. The elongated body includes a distal end having an electrode and a proximal end having a header connector portion for coupling the elongated body with an implantable medical device. The bobbin is disposed in the elongated body. The conductor is disposed in the elongated body and is electrically coupled with the header connector portion and the electrode. The conductor is wound around the bobbin to form first and second inductive coils that are axially separated from each other by an inter-coil gap formed from the bobbin. The first and second inductive coils have different self resonant frequencies.

摘要： An implant tool for use with an endocardial or other implantable lead having an extendable/retractable active fixation tip includes a housing, a shaft rotatably supported by the housing, and a shaft rotation mechanism for rotating the shaft through a predetermined angular travel. The shaft includes a lead attachment portion for selectively coupling a lead to the shaft such that the lead is rotatable with the shaft. The implant tool may include a control tab slidably supported by the housing, wherein longitudinal movement of the control tab actuates the shaft rotation mechanism. The shaft rotation mechanism may include a gear train, an electric motor, a double acting spring mechanism, or a retractable tape wound around the shaft. The gear train includes an input member coupled to the control tab and an output gear coupled to the shaft. The input member meshes with an input gear supported by the housing.

摘要： A medication infusion pump is provided of the type adapted for implantation into the body of a patient, and for programmable delivery of a selected medication through a catheter to the patient over an extended period of time. A side port assembly is mounted quickly and easily onto the pump and defines a flow path through which the medication is discharged to the catheter. The side port assembly includes an access port to permit transcutaneous needle access to the discharge flow path, in combination with a check valve to prevent backflow within the discharge flow path. The discharge side access port can be used to flush residue from the catheter, or in combination with a primary refill port on the pump to flush the pump and/or to determine actual pump stroke volume.
