  • Publication number: 20110034954
    Abstract: A method of treating a heart condition includes dispensing first and second sealant components to a myocardial infarction via an introducer extending through a percutaneous puncture in a subxiphoid region. The first and second sealant components combine to form a medical sealant material that bonds to the myocardial infarction to form a reinforcement for the myocardial infarction, wherein the reinforcement does not include a patch.

  • Patent number: 7881810
    Abstract: A chamber or vasculature of a heart may be accessed via the pericardial space of the heart. Initially, the pericardial space may be accessed via a transmyocardial approach or a subxiphoid approach. A lead or other implantable apparatus may thus be routed into the pericardial space, through myocardial tissue and into the chamber or vasculature. The lead or other apparatus may be used to sense activity in or provide therapy to the heart.

  • Patent number: 7397166
    Abstract: A peristaltic pump for conveying a fluid comprises a flexible tube having an outer surface and a lumen for carrying the fluid such as a therapeutic agent. The tube has a length defined by opposed ends of the tube, the outer surface of the body carrying a plurality of longitudinally spaced-apart electroactive polymer actuators. The plurality of actuators are adapted to be responsive to electrical signals for energizing the actuators sequentially along the length of the tube to move a lumen pinch-off along the length of the tube to thereby convey the fluid from one end of the tube to the other end by means of a peristaltic pumping action. The peristaltic pump may be incorporated into a medical lead, such as an endocardial pacing lead, carrying at least one electrode.

  • Patent number: 7313444
    Abstract: An implantable cardiac lead system suitable for placement in the coronary sinus region of the heart. The lead system comprises a lead having two or more non-helical bends in its distal portion. The two or more non-helical bends cooperate to prevent the lead from dislodgment or displacement inside the coronary sinus. The lead system may further comprise a stylet suitable for steering the lead into at least one of the coronary sinus vein, great cardiac vein, left marginal vein, left posterior ventricular vein, and small cardiac vein. The stylet is tapered in its distal portion to provide enhanced maneuverability and steerability inside the coronary sinus region. The lead system may also comprise an introducer which aids in introducing the lead into the heart.

  • Publication number: 20070239244
    Abstract: The intrapericardial lead includes a lead body having a proximal portion and a flexible, pre-curved distal end portion. The distal end portion carries at least one electrode assembly containing an electrode adapted to engage pericardial tissue. The distal end portion further carries a pre-curved flexible wire member having ends attached to spaced apart points along the distal end portion of the lead body, the flexible wire member having a normally expanded state wherein an intermediate portion of the wire member is spaced apart from the distal end portion, and a generally straightened state wherein the wire member and the distal end portion are disposed in a more parallel, adjacent relationship so as to present a small frontal area to facilitate delivery into the pericardial space. The wire member re-expands to its normal state after delivery into the percaridal space to anchor the distal end portion of the lead body relative to the pericardial tissue.

  • Patent number: 7272448
    Abstract: The lead body of a medical lead comprises a distal end portion carrying at least one electrode for placement in the pericardial sac of a human heart. The distal end portion of the lead body includes a multi-turn section having opposed ends, opposing forces applied to the ends tending to flatten the multi-turn section, the multi-turn section being thereby adapted to be retained within the pericardial sac. The turns of the multi-turn section may become progressively smaller from one end of the section to the other end of the section. The multi-turn section may have, in a relaxed state thereof, a generally conical, helical configuration. The at least one electrode may be carried adjacent to the end of the multi-turn section having the larger turns. Alternatively, the at least one electrode may be carried adjacent to the end of the multi-turn section having the smaller turns.
