  • Publication number: 20240041480
    Abstract: A catheter system with integrated fluidics management includes a first elongate, flexible tubular body having a proximal end, a distal end and at least one lumen, a hub on the proximal end of the tubular body, a valve system in communication with the hub, and a first port, a second port, and a third port in communication with the valve system. The valve system is configured to selectively place any one of the first port, the second port and the third port into communication with the lumen while simultaneously blocking the other two ports from communicating with the lumen.

  • Publication number: 20240033486
    Abstract: A method of priming an interventional device assembly includes providing the interventional device assembly including a first interventional device coupled to a first hub and a second interventional device coupled to a second hub arranged in a concentric stack, the second interventional device being positioned within a lumen of the first interventional device. The method includes coupling the interventional device assembly to a drive system while arranged in the concentric stack, axially advancing the first interventional device and the first hub relative to the second hub to decrease a depth of insertion of the second interventional device within the lumen of the first interventional device while maintaining a distal end of the second interventional device within the lumen of the first interventional device, and flushing the first interventional device with fluid after decreasing the depth of insertion of the second interventional device within the lumen of the first interventional device.

  • Publication number: 20100152531
    Abstract: An apparatus and method of preparing a cardiac harness for use in controllably delivering a medicament such as an mTOR inhibitor or aldosterone blockade from the surface of the cardiac harness to the epicardium of a patient's heart for the site-specific treatment of cardiac and non-cardiac maladies. The delivery of the medicament from the cardiac harness is achieved by: coating the medicament on the surface of the cardiac harness; coating the cardiac harness with a polymer material or dielectric material and impregnating the coating with the medicament; or by loading the medicament into an implant attached to the cardiac harness.

  • Publication number: 20090043152
    Abstract: A delivery system for providing and deploying a cardiac harness over a heart. The delivery system includes an introducer tube having a plurality of distal fingers biased into a compressed delivery diameter. A dilator tube is slidably mounted within the introducer tube for dilating the fingers into an expanded diameter for deploying a suction cup into secure attachment with the heart. The suction cup is used to manipulate the heart as the cardiac harness is also deployed from the dilator tube over the suction cup, and over the heart. The suction cup is shaped to securely attach to the apex of the heart in one embodiment.
