Devices, systems, and methods for facilitating flow from the heart to a blood pump

摘要

An apparatus includes a tubular member defining a lumen and a channel, and a support member. The tubular member has a connection portion configured to be coupled to an organ wall. An outer edge of the connection portion is configured to contact a first portion of an inner surface of the wall when the connection portion is in an expanded configuration such that an interior volume of the organ is in fluid communication with the lumen. The support member is movably disposed within the channel and is configured to minimize movement of the wall relative to the tubular member. An end portion of the support member is disposed within the channel when the support member is in a first configuration. The end portion of the support member configured to contact a second portion of the inner surface of the wall when the support member is in a second configuration.

1. An apparatus, comprising:
a tubular member defining a lumen therethrough, the tubular member including a connection portion configured to be coupled to a wall of a heart such that an interior volume of the heart is in fluid communication with the lumen; and a recirculation member disposed at least partially within the lumen of the tubular member, the recirculation member defining a flow pathway therethrough such that the interior volume of the heart is in fluid communication with the flow pathway, the flow pathway configured to convey a fluid into the volume of the heart to minimize movement of the wall relative to the tubular member, the recirculation member defining a plurality of apertures arranged along a distal portion of the recirculation member such that a portion of the fluid can exit each aperture from the plurality of apertures and into the interior volume of the heart, the plurality of apertures including a first aperture and a second aperture spaced apart longitudinally from the first aperture.
