Abstract: Several unique intracardiac pressure vents, placement catheters, methods of placement and methods of treating heart failure are presented. The intracardiac pressure vents presented allow sufficient flow from the left atrium to the right atrium to relieve elevated left atrial pressure and resulting patient symptoms but also limit the amount of flow from the right atrium to the left atrium to minimize the potential for thrombus or other embolic material from entering the arterial circulation. Retrievability during deployment is improved, in part, by providing at least one segment or portion of the device that is retained within the placement catheter while all other segments or portions of the device are deployed.

Abstract: The present disclosure relates to devices and methods for implanting a prosthesis into a heart of a mammal, such as a person. The disclosure includes a prosthesis that acts as a pressure vent between the left and right atria of the heart. The intracardiac pressure vents disclosed allow sufficient flow from the left atrium to the right atrium to relieve elevated left atrial pressure and resulting patient symptoms. The devices also limit the amount of flow from the right atrium to the left atrium to minimize the potential for thrombi or other embolic material from entering arterial circulation.

Abstract: A medical infusion fluid handling system, such as an APD system, may be arranged to de-cap and connect one or more lines (30) (such as solution lines) with one or more spikes (160) or other connection ports on a fluid handling cassette (24). This feature may reduce a likelihood of contamination since no human interaction is required to de-cap and connect the lines and spikes. For example, an APD system may include a carriage (146) arranged to receive a plurality of solution lines (30) each having a connector end (31a) and a cap (31). The carriage may move along a first direction so as to move the connector ends of the solution lines along the first direction, and a cap stripper (149) may be arranged to engage with caps on the solution lines on the carriage. The cap stripper may move in a second direction transverse to the first direction, as well as to move with the carriage along the first direction.

Abstract: Several unique intra-cardiac pressure vents, placement catheters, methods of placement and methods of treating heart failure are presented. The intra-cardiac pressure vents presented remain partially open under normal intra-cardiac pressures to allow sufficient flow from the left atrium to the right atrium to enable the relief of elevated left atrial pressure and resulting patient symptoms, and also limit the amount of flow from the right atrium to the left atrium by closing when the pressure in the right atrium exceeds the pressure in the left atrium by a predetermined amount.
