Abstract
A tissue wall of a biological lumen may be reinforced by embedding a material or structure into the tissue wall. The reinforcement material or structure may embed by application of outwardly directed force along an interior side of the tissue wall, threading, or injection. The reinforcement material or structure may act as an embedded scaffold that limits expansion or contraction of the tissue wall to pushing or pulling forces. An anchor device, such as a medical device, may anchor to the reinforced portion of the tissue wall.
Claims26
A method of reinforcing a tissue wall of a gastrointestinal tract lumen for anchoring a medical device directly or indirectly to the reinforced tissue wall, the method comprising:
- embedding a body of an embedment device into a portion of a tissue wall defining a gastrointestinal tract lumen, the body comprising a reinforcement material or structure that reinforces the portion of the tissue wall when embedded therein;
- and
- engaging the embedment device with one more anchor structures of an anchor device to anchor the anchor device within the lumen, wherein the anchor device does not completely overlap the body with a covered surface that applies outwardly directed pressure along the portion of the tissue wall sufficient to cause the body to unembed, and wherein the anchor device comprises a medical device or a platform to which a medical device is coupled or subsequently coupled in situ.
A method of reinforcing a tissue wall of a biological lumen, the method comprising:
- embedding a reinforcement material or structure into a portion of a tissue wall defining a gastrointestinal tract lumen, and wherein embedding the reinforcement material or structure comprises threading a wire along the portion of the tissue wall or injecting a polymer into the portion of the tissue wall;
- and
- anchoring an anchor device to the portion of the tissue wall, wherein the anchoring comprises penetrating into the tissue wall with the one more anchor structures of the anchor device and therein engaging the embedded reinforcement material or structure.
A method of reinforcing a tissue wall of a biological lumen, the method comprising:
- embedding a reinforcement material or structure into a portion of a tissue wall defining a gastrointestinal tract lumen, wherein the reinforcement material or structure comprises an embedment device having a body, wherein embedding the reinforcement material or structure comprises delivering the embedment device into the lumen and applying outwardly directed force along an interior side of the tissue wall to embed the body therein;
- delivering a positioning device into the lumen and positioning the positioning device within the lumen, interior of the reinforcement material or structure, to secure the body of the embedment device along the interior side of the tissue wall during the embedding, wherein the positioning device comprises a body and one or more projections, and wherein the one or more projections penetrate the tissue wall but not puncture an exterior side of the tissue wall;
- and
- anchoring an anchor device to the portion of the tissue wall, wherein the anchoring comprises penetrating into the tissue wall with the one more anchor structures of the anchor device and therein engaging the embedded reinforcement material or structure,
- wherein the body of the positioning device is absorbable or dissolvable or the method further comprises removing the positioning device after the embedment device has embedded the tissue wall.
