Claims20
A medical device, comprising:
- an elongate tether comprising a flexible middle portion and substantially rigid proximal and distal portions;
- an anchor disposed along a distal end of the tether and configured to engage a tissue wall of a right ventricle of a patient;
- and
- a plug slidably disposed along a proximal segment of the flexible middle portion.
1 more element
A plug, comprising:
- a central spine defining a lumen therethrough configured to slidably receive a tether;
- a framework extending over the central spine;
- and
- an impermeable cover disposed around the framework;
- wherein the plug is configured to move from a first configuration to a second configuration;
- and
- wherein the framework, when in the second configuration, includes a varying outer diameter proximal portion and a constant outer diameter distal portion.
4 more elements
