Mucosal tissue adhesion via textured surface

摘要

The present specification discloses porous materials, methods of forming such porous material, biocompatible implantable devices comprising such porous materials, and methods of making such biocompatible implantable devices. The porous material may be used to fix to the interior mucosal lining of a patient's gastrointestinal tract.

主权项

1. A method for anchoring an implant device to a mucosal lining of a patient's gastrointestinal tract comprising:
inserting a pre-formed implant device into the patient's gastrointestinal lumen, which defines a passage that allows for passage therethrough of the pre-formed implant and food, at least a portion of the implant device being formed of a substantially non-resorbable, biocompatible, elastomer matrix defining an array of interconnected pores structured to receive tissue ingrowth from the mucosal lining of the patient's gastrointestinal lumen to anchor the implant device to the mucosal lining; and placing the implant device within the passage defined by the patient's gastrointestinal lumen such that the array of interconnected pores contacts the mucosal lining such that the implant rests against the mucosal lining and extends into the passage defined by the gastrointestinal lumen and receives tissue ingrowth from the mucosal lining to anchor the implant device to the mucosal lining.
