1. A system for tissue resection in a body lumen of a patient, the system comprising:
an endoscope;
a backstop delivery device extendable through the endoscope and positionable in the body lumen at a location of selected tissue for resection;
a backstop including a covering deployable by the backstop delivery device; and
a tissue resecting device extendable through the endoscope for resecting the selected tissue for resection;
wherein the covering:
is deployable to an outer surface of the body lumen;
has one or more anchoring mechanisms disposed on an edge thereof and securable to the outer surface of the body lumen;
is-expandable to cover the selected tissue for resection; and
is configured, when expanded and secured to the body lumen, to define a space between the covering and the outer surface of the body lumen to provide clearance between the covering and the outer surface of the body lumen during tissue resection.
