The present disclosure relates to the field of medical devices. In particular, the present disclosure relates to devices with a shaft having an effective working length that is adjustable relative to a connector of the device and/or a working channel of an endoscope, and methods for their use, such as devices and methods for delivery of a stent.

Devices with an adjustable effective working shaft length

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 esophageal atresia bridge device including a proximal anchor, a distal anchor, and a brace extending between the proximal anchor and the distal anchor. The brace permits the proximal anchor to move toward the distal anchor to apply a controlled tension that pulls the esophagus together and stretches the esophagus over time. A method of treating esophageal atresia may include inserting an elongate member of an esophageal atresia device into a mouth of a patient, the esophageal atresia device including a rotatable member including a threaded region, and rotating the rotatable member relative to the elongate member to longitudinally move the distal end of the elongate member relative to the rotatable member in order to apply a force to a proximal pouch of the patient's esophagus.

Esophageal atresia bridge device and methods of treating esophageal atresia

The present disclosure relates to the field of medical devices. Specifically, the present disclosure relates to devices, systems and methods for extending a working channel of an endoscope, such as for delivery of a stent.

Devices and methods for extending a working channel

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.

Stent including anti-migration capabilities

A lumen-apposing access system may include a catheter and a cauterization tip. The cauterization tip may include a biasing member and a cautery element. The cauterization tip may move relative to the catheter between a first position in which the cautery element is electrically inactive, and a second position in which the cautery element is electrically active. The biasing member biases the cautery element in the first position.

Cauterizing device for use with stents

A medical instrument may include a tube, a sheath provided around and coaxial with the tube, and an inflatable balloon at a distal end of the sheath. The balloon may receive a fluid from a lumen of the sheath, and may have a central opening along a longitudinal axis thereof, and into which the tube extends, a proximal portion, a middle portion adjacent to and distal of the proximal portion, and a distal portion adjacent to and proximal of the middle portion. When the balloon is inflated with the fluid, a maximum diameter of the middle portion may be less than a maximum diameter of the proximal portion, and less than a maximum diameter of the distal portion. The medical instrument may also include an extraction member provided at a distal end of the tube, distal to the balloon, and movable axially relative to the balloon.

Medical instrument having a balloon and an extraction member

An example medical device is disclosed. The example medical device includes a tubular scaffold. The scaffold includes a longitudinal axis, an inner surface and an outer surface. The medical device also includes a flexible valve extending radially inward from the inner surface of the scaffold. The valve includes an annular chamber extending circumferentially around the inner surface of the scaffold and is configured to shift from a closed configuration to an open configuration.

Esophageal stent including a valve member

The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to devices and methods for controlled delivery of a stent, such as a self-expanding stent, and more particularly for controlling the full deployment of a stent in incremental steps from a sheath and for controlling the reconstrainment of a stent in incremental steps within a sheath.

Devices and methods for controlled delivery of a 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 may include a tubular sleeve configured for implantation in a body lumen, the sleeve having a first configuration with a first rigidity and a second configuration with a second rigidity greater than the first rigidity, the sleeve including: a flexible membrane defining an interior lumen; and a channel extending along the membrane.

Deployable sleeves and related methods

An esophageal atresia bridge device including a proximal anchor, a distal anchor, and a brace extending between the proximal anchor and the distal anchor. The brace permits the proximal anchor to move toward the distal anchor to apply a controlled tension that pulls the esophagus together and stretches the esophagus over time.
