The invention relates to a defibrillator system having means for transferring electrical energy coupled to tranvenously implantable cardiac leads and methods for transvenous implantation. The cardiac lead has an elongated first member having a tip on one end thereof, an implantable object coupled to the first member, such as a defibrillator electrode, expandable from a collapsed position to an extended position generally away from the lead and means for expanding the object from the collapsed position to the extended position. The transvenous implantation method of the present invention involves entering a vein of a patient, translating through the vein to the patient's cardium atrium, puncturing the atrial lateral wall and forming a hole therein, exiting the atrium through the hole to the pericardial space and inserting the object into the pericardial space.

Defibrillator system with cardiac leads and method for transvenous

The improved transvenous implantation method of the present invention involves entering a vein of a patient, translating through the vein to the patient's cardium atrium, anchoring onto the atrial lateral wall, puncturing the atrial lateral wall and forming a hole therein, exiting the atrium through the hole to the pericardial space and inserting the object into the pericardial space. The present invention also includes a method for the transvenous repair of a wound in the atrial lateral wall.

Method for transvenous implantation of objects into the pericardial

A sensing system for detecting the frequency and amplitude of motion of a patient's diaphragm, having a transducer for detecting movement, transvenously implantable in a patient's cardiovascular system; a lead coupled to the transducer, transvenously implanatable in a patient's cardiovascular system; and a sensing instrument coupled to the lead for correlating transducer movement with the frequency and amplitude of diaphragm motion. A method for sensing the frequency and amplitude of motion of a patient's diaphragm including transvenously implanting in a patient's cardiovascular system a transducer capable of measuring movement frequency and amplitude; detecting the frequency and amplitude of movement of the transducer; and correlating transducer movement with the frequency and amplitude of the patient's diaphragm movement.

Sensing system and method for sensing minute ventilation

The invention relates to an angioplasty guiding catheter and methods for performing coronary angioplasty on a patient, to dilate constrictions in blood vessels. The guiding catheter has an elongated first member having at least one lumen therethrough and a tip, at least one leg member, coupled to the first member, radially extendable from a retracted position generally in contact with the first member to an extended position generally away from the first member, for abutment against an internal wall of patient's cardiovascular system, and means for extending the leg member from the retracted position to the extended position, coupled to the leg member. The angioplasty methods of the present invention involves entering the patient's cardiovascular system, pericutaneously patient's cardiovascular system to a desired translating through the location proximate a constriction in a blood vessel, abutting against an internal wall of the cardiovascular system, advancing towards the constriction in a direction generally opposite the abutting, for overcoming resistance by the constriction to the advancing and dilating the vessel at the constriction site.
