Medical devices and methods for making and using medical devices are disclosed. An example medical device may include an access valve that may be retrieved after implantation. The access valve may include a frame having a lumen, a self-expandable member extending through the lumen, and an elastic membrane extending through the lumen and a second end of the frame to releasably seal the lumen. The access valve may releasably attach to a wall of a patient and releasably seal an opening through the wall. The access valve may be attached to the wall by placing the frame adjacent the wall, extending the self-expandable member through the opening in the wall, and expanding the self-expandable member such that the self-expandable member applies a first force against the wall and a second force opposite the first force against the frame to sandwich the wall between the self-expandable member and the frame.

Retrievable access valve

The present disclosure relates generally to the field of medical devices and establishing fluid communication between body lumens. In particular, the present disclosure relates to devices and methods for establishing a controlled flow or access passage between body lumens.

Flow control valve

An esophageal stent may include an expandable framework having a first end, a second end, and a central longitudinal axis extending from the first end to the second end, the expandable framework being configured to expand from a radially collapsed configuration to a radially expanded configuration, and a polymeric outer sleeve disposed radially outward of and spaced apart from a body region of the expandable framework. The expandable framework may include a plurality of anti-migration supports extending radially outward from the body region of the expandable framework toward the polymeric outer sleeve.

Radial adjusting self-expanding stent with anti-migration features

The present disclosure relates generally to the field of medical devices and establishing fluid communication between body lumens. In particular, the present disclosure relates to devices and methods for establishing a controlled flow or access passage between body lumens. For example, a device may include an elongate tubular body defining a lumen along a length thereof. The elongate tubular body may have an unexpanded configuration and an expanded configuration. In the expanded configuration, a proximal portion of the elongate tubular body may expand into a proximal retention member and a distal portion of the elongate tubular body may expand into a distal retention member, leaving a cylindrical saddle region extending therebetween. The cylindrical saddle region may include a constricted portion configured to move between a first diameter configuration and a second diameter configuration larger than the first diameter configuration.

Flow control stent

A device for occluding flow of materials is formed as a simple structure permitting a compact delivery configuration which may shift to an expanded deployment configuration. The device has at least one expandable portion formed of a plurality of elongated longitudinally extending frame elements. The frame elements may be spaced apart to define spaces therebetween, and a flexible occlusive material may be provided to block flow of material through such spaces. A flexible occlusive material may form one of two expandable portions of the device without the need for frame elements.

Devices, systems, and methods for occluding an anatomical passage

A medical system includes a porous body positioned at a target site within a subject, a tube including a wall defining a tube lumen, where the tube is connected to the porous body at a first end of the tube, and a sealing device to seal the target site from a body lumen. When the sealing device seals the target site from the body lumen, the tube extends from the target site into the body lumen.

Endoluminal sealing devices and related methods of use

According to one aspect, an apparatus for treating tissue may include an elongate tube. The elongate tube may include a slot extending longitudinally along a first side of the elongate tube, a first elongate jaw member on a first side of the slot, and a second elongate jaw member on a second side of the slot. The apparatus may also include a shaft coupled to the elongate tube along a second side of the elongate tube. The first elongate jaw member may be movably coupled to the shaft, such that the first elongate jaw member may be movable toward the second elongate jaw member to converge tissue walls within the slot and cut the tissue walls within the slot.

Devices and related methods for gastrectomies

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.

Stent anchoring system

An illustrative stent includes an elongated tubular member comprising at least one strut or filament forming a tubular wall having a plurality of cells extending through a thickness of the tubular wall. The elongated tubular member may be configured to move between a radially collapsed configuration and a radially expanded configuration. A coating is disposed on the elongated tubular member and spanning the plurality of cells. The coating forms a pocket within at least some of the cells of the plurality of cells and extends radially inward of the tubular wall to define a void. In some instances, a partition or wall is positioned within at least some of the pockets and transects the void.

Anti-migration stent

An illustrative stent may comprise an elongated tubular member having a longitudinal axis, the elongated tubular member comprising at least one knitted filament forming a plurality of twisted knit stitches with intermediate rung portions extending circumferentially between radially adjacent twisted knit stitches. Each twisted knit stitch may be interconnected with a longitudinally adjacent twisted knit stitch forming a series of linked stitches. The elongated tubular member may be configured to move between a collapsed configuration and an expanded configuration, wherein in the collapsed configuration the series of linked stitches form longitudinal columns and in the expanded configuration the series of linked stitches extend helically around the elongated tubular member.

Stent with anti-migration feature

A medical device for treating esophageal atresia may include a woven tubular member having a first end, a second end, and a body portion extending between the first end and the second end. The first end may have a first flange extending radially outwardly from the body portion. The second end may have a second flange extending radially outwardly from the body portion. The woven tubular member may be configured to transition from an initially-deployed state toward an equilibrium state. In the initially-deployed state, the body portion may include an inner region extending from the first flange to a transition region and an outer region extending from the second flange to the transition region. The outer region may surround the inner region. The woven tubular member may be self-biased to be in the equilibrium state.
