Abstract

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.

Claims

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 an organ such that an interior volume of the organ is in fluid communication with the lumen; and

a support member coupled to the tubular member, the support member configured to minimize movement of the wall relative to the tubular member.

2. An apparatus, comprising:

a tubular member defining a lumen therethrough, the tubular member including a connection portion configured to move from a collapsed configuration to an expanded configuration, an outer edge of the connection portion configured to contact a first portion of an inner surface of a wall of an organ when the connection portion is in its expanded configuration such that an interior volume of the organ is in fluid communication with the lumen and is fluidically isolated from a volume outside of the organ; and

a support member coupled to the tubular member, the support member configured to minimize movement of the wall relative to the tubular member, the support member configured to move between a first configuration and a second configuration, the support member configured to contact a second portion of the inner surface of the wall when the support member is in its second configuration.
