1. An apparatus comprising:
a support structure including a plurality of absorbable filaments configured to support a tissue and degrade within a defined time period; and
a membrane arranged about an entirety of the support structure including the plurality of absorbable filaments and an entirety of at least one of a proximal end and a distal end, the membrane configured to contain fragments of the plurality of absorbable filaments in response to a fracture or degradation of a filament, the membrane defining a first layer and a second layer, the plurality of absorbable filaments being arranged between layers of the membrane such that the first layer and the second layer of the membrane sandwich the plurality of absorbable filaments, wherein the proximal end is an integral portion of a proximal disk comprising a proximal expanded diameter portion such that the proximal end does not protrude beyond a proximal end of the proximal disk.
