• a treatment device with a proximal end, a distal end, and a longitudinal extent therebetween, and comprising a wall defining a lumen therethrough and having an interior side and an exterior side and at least one wall region configured to permit tissue ingrowth, and a liner having a liner wall extending through at least a portion of the treatment device wall lumen and defining a liner lumen therethrough;
• and
• a removal device configured to fit within the liner lumen;
• wherein:
• said removal device has an exterior shape configured to correspond with the shape of said interior side of said treatment device when said removal device is within the liner lumen;
• and
• said liner includes a disruption zone longitudinally along and spaced radially inwardly of the treatment device wall region configured to permit tissue ingrowth, the disruption zone configured to facilitate disruption of said liner wall by at least one of breaking, tearing, or rupturing of said liner wall.
