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.
Core Innovation
The invention reinforces a tissue wall of a gastrointestinal tract lumen for anchoring a medical device directly or indirectly to the reinforced tissue wall. It embeds a body of an embedment device into a portion of a tissue wall defining a gastrointestinal tract lumen, where the body comprises a reinforcement material or structure that reinforces the tissue wall portion when embedded therein.
After embedding, the invention anchors the embedded body within the lumen by engaging the embedment device with one or more anchor structures of an anchor device. The anchor device does not completely overlap the body with a covered surface that applies outwardly directed pressure along the tissue wall portion sufficient to cause the body to unembed, and the anchor device comprises a medical device or a platform to which a medical device is coupled or subsequently coupled in situ.
The invention further includes embedding and anchoring approaches based on the reinforcement material or structure and the forces applied during embedding. These include embedding by threading a wire along the tissue wall portion or injecting a polymer, embedding via an embedment device that is delivered into the lumen and applies outwardly directed force along an interior side to embed the body, and using a positioning device with projections that penetrate the tissue wall but not puncture an exterior side, with the positioning device being absorbable or dissolvable or removed after embedding.
Claims Coverage
The provided excerpt contains three independent claims. Across these, the core claim coverage centers on embedding a reinforcement material or structure in a gastrointestinal tract lumen tissue wall and anchoring an anchor device via engagement or penetration into the tissue wall to secure the embedded reinforcement, including constraints on anchor-device overlap and outwardly directed pressure, and optional in situ coupling platforms and positioning devices.
Embedment of a reinforcement body in a gastrointestinal lumen tissue wall
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.
Anchoring by engaging embedment device with anchor structures
Engaging the embedment device with one or more anchor structures of an anchor device to anchor the anchor device within the lumen.
Anchor device does not completely overlap with pressure sufficient to cause unembedment
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.
Anchor device is a medical-device platform or coupled in situ
The anchor device comprises a medical device or a platform to which a medical device is coupled or subsequently coupled in situ.
Wire threading or polymer injection embedding of reinforcement
Embedding a reinforcement material or structure into a portion of a tissue wall defining a gastrointestinal tract lumen, 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.
Penetration-based anchoring engaging embedded reinforcement
Anchoring an anchor device to the portion of the tissue wall, wherein the anchoring comprises penetrating into the tissue wall with the one or more anchor structures of the anchor device and therein engaging the embedded reinforcement material or structure.
Embedding via outwardly directed force along an interior side
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.
Positioning device with projections that penetrate without puncturing exterior side
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.
Absorbable or dissolvable positioning device or removal after embedding
The body of the positioning device is absorbable or dissolvable or the positioning device is removed after the embedment device has embedded the tissue wall.
Across the independent claims, the inventive coverage is directed to embedding a reinforcement material or structure within a gastrointestinal tract lumen tissue wall and anchoring an anchor device by engaging the embedded reinforcement using one or more anchor structures that penetrate into the tissue wall. The coverage further specifies that the anchor device does not completely overlap the embedded body with a covered surface applying outwardly directed pressure sufficient to cause unembedment, and it includes embedding via threading a wire or injecting a polymer, as well as positioning-device projections that penetrate without puncturing the exterior side with optional absorbable or dissolvable positioning or removal.
