Abstract: The present disclosure relates generally to stents, systems, and methods for anchoring devices within a body lumen by cooperation between the device and the body musculature. A device comprising an elongate tubular member may be deployed within a body lumen, where the body lumen includes a sphincter that regulates flow through the body lumen. The elongate tubular member includes a sleeve formed from a flexible membrane and one or more stents disposed at either or both ends of the sleeve. In some embodiments, the stents may be treatment stents configured to treat a portion of the body lumen. The elongate tubular member may be deployed within the body lumen such that the flexible membrane aligns with and moves in coordination with the sphincter, thereby increasing retention forces acting upon the elongate tubular member when the sphincter is closed to minimize treatment stent migration.

Abstract: The present disclosure relates generally to stents, systems, and methods for gastrointestinal treatment. In some embodiments, a stent may include a tubular scaffold having a first end opposite a second end, wherein a lumen extends between the first and second ends. The tubular scaffold may include a flared section and a medial section extending from the flared section, wherein a first diameter of the flared section is greater than a second diameter of the medial section. The stent may further include a liner extending partially along a surface of the tubular scaffold, wherein the liner is spaced from an anchoring region of the flared section to promote tissue ingrowth with the flared section.

CPC classification number: A61F5/0079
Abstract: An occlusion device including a first component configured to anchor the occlusion device with respect to a deployment site, and a second component configured to occlude a lumen through the occlusion device. The first component may be in the form of a stent. The second component may be in the form of a stent or in the form of a liner within the first component. The second component includes an occlusion structure configured to extend across (e.g., transverse to the longitudinal axis of) the lumen of the first component. The occlusion structure may be on a retention member of the second component which engages with a retention member of the first component. Additionally or alternatively, the occlusion structure may be a portion of a liner cinched to occlude the lumen through the occlusion device.

Abstract: An example medical device for treating a body lumen is disclosed. The medical device includes an expandable scaffold including first and second regions, each of the first and second regions include a plurality of interstices located therein. The medical device also includes a covering spanning each of the plurality of interstices of the first region. The second region is free of the covering. A biodegradable gripping material is disposed on an outer surface of the covering. Further, the expandable scaffold is configured to shift from a collapsed state to an expanded state and the second region is configured to contact an inner surface of the body lumen in the expanded state. Additionally, the gripping material is designed to initially prevent migration of the expandable scaffold upon implantation in the body lumen until the second region is secured to the inner surface of the body lumen.

Abstract: The present disclosure relates generally to the field of medical devices and medical device delivery. In particular, the present disclosure relates to medical devices and delivery systems for positioning and delivering medical devices with an unsupported structure, for example, within a distant and/or tortuous portion of body lumen. For example, a delivery system may position a supported structure of a medical device within a proximal portion of a body lumen and an unsupported structure of the medical device within a distal portion of the body lumen. Examples include delivery systems within an unsupported structure of a medical device to be delivered, wherein a number of balloons are arranged un-inflated within the unsupported, with a distal balloon removably attached to a distal portion of the unsupported structure, and the balloons are inflatable in series to deploy the unsupported structure linearly from the distal end of the delivery system.

Abstract: An illustrative stent may comprise an elongated tubular member having a first end and a second end and an intermediate region disposed therebetween. The elongated tubular member may include at least one barb attached thereto. The barb may be configured to be tucked under a filament of the stent during delivery of the stent and protrude radially from the stent, when the stent is deployed.

Abstract: A system for treating a body lumen including a first stent configured to be positioned in a body lumen and a second stent configured to be positioned in the lumen of the first stent prior to removing the first stent from the body lumen. The first stent includes a liner disposed radially inward of the tubular scaffold of the first stent to permit tissue ingrowth within a tissue ingrowth region defined between the liner and the tubular scaffold. The retrieval stent is configured to be expanded within the previously implanted first stent to cause tissue to recede from the tissue ingrowth region to facilitate removal of the first stent from the body lumen.

Abstract: A braided stent having a plurality of retrieval and/or repositioning levers includes a stent body formed of a plurality of wires interbraided in a braided pattern. The repositioning and/or retrieval levers have a loop portion extending radially away from the stent body and first and second legs extending along the stent body. The levers are configured to be actuated radially inward toward the central longitudinal axis of the stent by a radially inwardly directed force to radially collapse the stent.
