Devices and methods for endoscopic patch delivery

A method of delivering a patch to a target site of a patient, the method comprising:

• introducing a system comprising an endoscope into a gastrointestinal tract of a patient, wherein the system includes a patch comprising a biocompatible material and
• a cap fixedly coupled to a distal end of the endoscope, wherein the patch is secured to an outer surface of the cap with a flexible band, covers a distal opening of the cap, and is releasable from the cap;
• positioning a distal end of the endoscope proximate a target site;
• and
• applying the patch to the target site while releasing the patch from cap;
• wherein releasing the patch from the cap includes actuating a wire to release the flexible band.

A medical system comprising:

• an endoscope defining at least one working channel;
• a patch comprising a biocompatible material;
• and
• a cap coupled to a distal end of the endoscope, the patch covering a distal end of the cap and being releasable from the cap;
• wherein the patch is secured to an outer surface of the cap with a flexible band;
• wherein a wire extending through the at least one working channel is coupled to the flexible band;
• wherein the distal end of the endoscope includes an optical device, and the patch includes an opening aligned with the optical device.
