Abstract: A device for performing chest compressions for CPR in coordination with applying electro-stimulus for additional resuscitative actions such as electro-ventilation, electro-counterpulsion, and defibrillation. The device includes a chest compression mechanism, electrodes and power supply for electro-stimulus, and a control system for applying electro-stimulus in coordination with the action of the chest compression mechanism.

Abstract: The present invention relates to a medical device for placement at a predetermined location within a passageway of the human body, and more particularly, relates to a flexible embolization device which may be delivered by a catheter to a pre-selected position within a blood vessel to thereby embolize a blood vessel or a blood vessel defect, such as an aneurysm or fistula. Specifically, the embolization device comprises an elongated coil having a lumen, the coil and lumen being at least partially embedded in an elongated foam member comprising, in some embodiments, a flexible, biodegradable, water insoluble, open, interconnecting-cell foam material having embolic characteristics, and capable of allowing cell proliferation into the open cell foam interior.

Abstract: Catheter shaft tubes and methods for making them are described, in which a tubular member has two or more polymer layers, with some kind of reinforcement between at least two of the polymer layers. An inner polymer layer has a lower melting temperature than an outer polymer layer.

Abstract: A medical device for placing an embolic device, such as an embolic coil, at a predetermined site within a vessel of the body including a delivery catheter and a flexible pusher member movably disposed within the catheter. An embolic device is detachably coupled to the pusher member and is retained in place on the distal end of the pusher member by a detachment filament. When the embolic device is advanced to the predetermined site within the vessel, the detachment filament is decoupled from the embolic device to thereby release the embolic device.

Abstract: Improved automatic chest compression systems which use constricting belts, repeatedly inflating bladders, or reciprocating pistons to compress the chest. A bladder is placed between the chest and the particular mechanism used to compress the chest during CPR. The bladder maximizes the effectiveness of chest compressions.

Abstract: A balloon catheter for medical treatment of a patient, including therapeutic dilatation or deployment of medical devices such as stents or grafts. The balloon catheter has an “over-the-wire configuration, including a proximal hub defining an inflation port and a guidewire port, a flexible shaft defining an inflation lumen and a guidewire lumen, a balloon near a distal end of the catheter, and a distal guidewire port. At least a portion of the shaft has an inner tubular body defining at least a portion of the guidewire lumen, surrounded by an outer tubular body defining at least a portion of the inflation lumen. A proximal portion of the inner body is reinforced by a hypotube, which provides much greater column strength and torsional stiffness. A distal end of the hypotube provides a graduated flexibility transition with a distal spiral-cut segment, in which the pitch of the spiral cut pattern decreases to provide increasing flexibility.

Abstract: A resuscitation device for automatic compression of victim's chest using a compression belt which exerts force evenly over the entire thoracic cavity. The belt is constricted and relaxed through a motorized spool assembly which repeatedly tightens the belt and relaxes the belt to provide repeated and rapid chest compression. An assembly includes various resuscitation devices including chest compression devices, defibrillation devices, and airway management devices, along with communications devices and senses with initiate communications with emergency medical personnel automatically upon use of the device.

Abstract: A vascular occlusive device, such as an embolic coil, having thrombogenic fibers extending from the coil and having an outer barrier which encapsulates and flattens the fibers along the sides of the embolic coil for preventing activation of the coil until the outer barrier has been dissolved, or removed, from the embolic coil.

Abstract: A system for performing chest compression and abdominal compression for Cardiopulmonary Resuscitation. The system includes a motor and gearbox including a system of clutches and brakes which allow for controlling and limiting the movement of compressing mechanisms operating on the chest and the abdomen of a patient.

Abstract: A vascular occlusive device which includes a support structure and a bioactive coating disposed onto the support structure and an outer barrier coating which serves to prevent a reaction between the bioactive agent and bodily fluids until the outer barrier is activated by applying an external agent to the outer barrier.

Abstract: A method of treating cardiac arrest patients using epinephrine and a device that uses a belt to perform anterior-posterior closed chest compressions. In animal experiments the combination of epinephrine and a belt-driven anterior-posterior chest compression device produced high levels of coronary perfusion pressure, myocardial blood flow and cerebral blood flow relative to both pre-arrest levels and relative to conventional CPR techniques.

Abstract: A catheter device for creating linear lesions in endocardial tissue or other body tissue is described. The catheter includes an inner shaft telescopically received within an outer shaft. The inner shaft has one or more spaced apart electrodes along its distal section. The outer shaft member includes a fluid permeable window positionable to selectively overlay some or all of the electrodes when the relative positioning of the inner and outer shaft members is adjusted. During use, the window is positioned adjacent to the body tissue which is to be ablated and at least a portion of the electrodes are exposed through the window. RF energy is delivered to the electrodes while saline or other conductive fluid is simultaneously delivered through the infusion tube.
