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： 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： Methods and systems for transvenously accessing the pericardial space via the vascular system and atrial wall, particularly through the superior vena cava and right atrial wall, to deliver a pharmacologic agent, particularly a NO-donor drug, to the heart are disclosed. A proximal connector of an infusion catheter is coupled to an infusion pump, and a distal catheter segment having a distal infusion catheter lumen end opening is disposed in the pericardial space. The implantable infusion pump is operable in conjunction with an implantable ischemia monitor to monitor the ischemic state and trigger delivery or regulate the periodic delivery of the pharmacologic agent to optimally treat ischemia. The patient may operate a patient activator that the patient when feeling ischemia symptoms to transmit a signal that is received by the implantable infusion pump and triggers delivery of a bolus and/or continuous infusion.

摘要： A medical system for electrical stimulation includes a first column of electrodes, a second column of electrodes, an expandable member disposed between first and second columns, and an expansion mechanism adapted to transmit an externally applied pressure to the expandable member. The pressure expands the expandable member in order to force the first column of electrodes apart from the second column of electrodes. The first and second columns, disposed side-by-side, may be inserted through a percutaneous needle and into a epidural space, alongside a spinal cord; after insertion, the first column may be forced apart from the second column by applying the pressure to the expandable member.

摘要： A multilumen catheter having tubings extending into lumens within the catheter. The lumens may be used for blood, drugs or other medicants. The lumens may also be used for sensors. The junction element, external to the patient, connects the tubings to the lumens. The tubings, also external to the patient, connect to infusion members, to which one or more infusion systems may be connected to deliver blood, drugs and other medicants to the patient. A sensor having a sensing element may extend through the sensor lumen and be positioned internal to the patient for physiological parameter sensing. An external portion of the sensor may be connected to associated electronics to provide automatic monitoring of the physiological parameters and automatic delivery and control of the infusants. Also, a central line catheter for delivering fluids directly into a main artery or vein near the heart, which contains a first lumen to deliver a fluid through the central line catheter and a second lumen containing a sensor capable indicating a characteristic level in blood. The first lumen delivers the fluid downstream of the sensor to prevent any interference between the fluid delivery and the sensor readings. In other versions, the central line catheter can have additional lumens for additional purposes. In addition, the central line catheter can further include a flush sleeve to remove debris around the sensor.

摘要： A cardiac transvenous defibrillation lead has a continuous coil conductor within a layer of insulation. A portion of the coil conductor is exposed as a defibrillation electrode. In order to enhance fluoroscopic visualization of the exposed electrode during implant, the end of the exposed electrode is marked with a radiopaque element. The element may be in the form of an adhesive filled with radiopaque material that is used to backfill under the layer of insulation. Alternatively, a tube made of radiopaque material may be installed between the layer of insulation and the coil conductor.
