摘要: A jacket of biological compatible material has an internal volume dimensioned for an apex of the heart to be inserted into the volume and for the jacket to be slipped over the heart. The jacket has a longitudinal dimension between upper and lower ends sufficient for the jacket to surround a lower portion of the heart with the jacket surrounding a valvular annulus of the heart and further surrounding the lower portion to cover at least the ventricular lower extremities of the heart. The jacket is adapted to be secured to the heart with the jacket surrounding at least the valvular annulus and the ventricular lower extremities. The jacket is adjustable on the heart to snugly conform to an external geometry of the heart and assume a maximum adjusted volume for the jacket to constrain circumferential expansion of the heart beyond the maximum adjusted volume during diastole and to permit unimpeded contraction of the heart during systole.

摘要: A cardiac support device comprising a jacket of flexible and biocompatible material having a first axis for alignment generally parallel to a longitudinal axis of a patient's heart and a second axis that is transverse to the first axis. The material exhibits an amount of expansion in response to a force applied to the material along the first axis that is different than an amount of expansion in response to the force applied to the material along the second axis.

摘要: An assembly and method for effecting the condition of a mitral valve annulus of a heart includes a guide wire configured to be fed into the coronary sinus of the heart, and a mitral valve annulus therapy device configured to be slidingly received on the guide wire and advanced into the coronary sinus of the heart on the guide wire. A guide tube may further be employed for guiding the device into the coronary sinus. An introducer which may be employed for pushing the device into or pulling device out of the heart has a mechanism for releasably locking to the device. This enables substitution of the device if needed. Also, the crossover point of the circumflex artery and coronary sinus may be determined and avoided when the device is deployed.

摘要: In a method for substantially isolating cardiac circulation from systemic circulation, flow between the coronary sinus and the right atrium is occluded. A venous collection device having a collection lumen and a support structure is located in the coronary sinus. The support structure is used to maintain patency of the coronary sinus during collection of fluid through the collection lumen. An artificial flow path is provided between the collection lumen and the one or more coronary arteries, thus isolating the cardiac circulation. According to the method, cardiac pumping for systemic circulation can be maintained during isolation of the cardiac circulation.

摘要: A method for delivering a polynucleotide to cardiac tissue, including substantially isolating the coronary venous circulation from systemic circulation, and introducing a polynucleotide into the isolated coronary venous circulation to effect localized transfection of cardiac tissue. The polynucleotide advantageously produces a therapeutic effect, such as increasing or decreasing the expression level of a protein in the cardiac tissue.

摘要: Methods and apparatus for correlating event notifications between agents in a management network are provided. An agent constructs a network notification in response to receiving an event notification. If the received event notification is associated with a prior notification already received and stored by the agent, a correlation attribute is added to the constructed network notification. If the received notification matches a peer agent notification category that another agent in the management network is interested in receiving, the constructed network notification is sent to the other agent.
