Abstract: A laser crafting apparatus for directing electromagnetic radiation toward a workpiece may include various features. For example, the laser crafting apparatus may include a material support tray that is removably supported within an internal volume of the laser crafting apparatus. Further, the apparatus may include pre-filter disposed in a ventilation pathway between a workspace region of the internal volume and an extractor fan. The laser crafting apparatus may include a laser carriage assembly that houses a laser module and the assembly may include a lens tray detachably coupled to the support structure of the laser carriage assembly. In various embodiments, the laser crafting apparatus includes a lid having a radiation attenuation layer and a fire suppression layer.

Abstract: A method of creating a digital activity may include selecting an interactive digital design element to be added to the digital activity, the interactive digital design element configured to allow multiple users to interact with the interactive digital design element when deploying the digital activity. The method may include generating a data structure, the data structure representative of a repository into which data representative of user inputs are stored when interacting with the interactive digital design element when deployed. The method may include deploying the interactive digital design element in a visual space shared between the multiple users.

Abstract: A retrieval catheter and methods of use are described for removing a heart valve therapy such as a leaflet clip or artificial leaflet cord. The retrieval catheter can include a cutting element and a basket, piercing element, clamping mechanism, or similar grasping device. The method includes delivering a catheter to the region of the heart valve therapy and then manipulating the catheter and associated instruments to cut tissue as necessary and then remove the heart valve therapy and withdraw the catheter.

Abstract: Elongate flexible medical devices can be capable of axial elongation through the mechanism of eversion or toposcopic expansion. In general, this may be accomplished by providing a flexible tubular device having a proximal end and a distal end. Retraction of the distal end in a proximal direction through the tubular body inverts the tube upon itself, causing an axial shortening of the overall length of the device. An original length of the device can be restored by coupling a pressurized media to the proximal end of the sleeve. If the distal end of the sleeve is temporarily restricted or closed, the pressurized media causes the distal end of the sleeve to travel distally until the full length of the sleeve has been restored.

Abstract: Luminal devices are described. In one embodiment, a luminal device includes an esophageal stent and an anchoring membrane coupled to the esophageal stent. The anchoring membrane may be configured to be coupled to an esophageal wall with a tissue anchor placed through the anchoring membrane. The anchoring membrane may be configured to be pierced to allow the tissue anchor to be placed through the anchoring membrane. Methods for attaching a luminal device to the esophageal wall are described. In one embodiment, a method may include forming a bulge in an anchoring membrane of the luminal device and the esophageal wall, piercing the bulge from a first side of the anchoring membrane and a first side of the esophageal wall, placing a second retention element of a tissue anchor on a second side of the esophageal wall; and placing a tension element of the tissue anchor through the anchoring membrane and the esophageal wall. The tension element may be coupled to the second retention element.

Abstract: Gastrointestinal bypass devices are described. In one embodiment, a gastrointestinal bypass device may include an anchoring membrane configured to be attached to a wall of an esophagus with a tissue anchor placed through the anchoring membrane. The anchoring membrane may be configured to be pierced to allow the tissue anchor to be placed through the anchoring membrane. Methods for attaching a device to a tissue wall are described. In one embodiment, a method may include forming a bulge in an anchoring membrane of the device and the tissue wall, piercing the bulge from a first side of the anchoring membrane and a first side of the tissue wall, placing a second retention element of a tissue anchor on a second side of the tissue wall, and, placing a tension element of the tissue anchor through the anchoring membrane and the tissue wall. The tension element may be coupled to the second retention element. The method may further include placing a first retention element on the first side of the anchoring membrane.

Abstract: Delivery devices are described. In one embodiment, a delivery device includes a catheter and a sealing pad coupled to an outer surface of the catheter. The delivery device may further include a recess formed in an outer surface of the catheter. The sealing pad may be coupled in the recess. Methods for delivering a tubular device are described. In one embodiment, a method may include inserting a distal end of a catheter into a lumen of a tubular device. The catheter may include a sealing pad coupled to an outer surface of the catheter. The method also includes positioning the sealing pad inside a drawstring coupled circumferentially to the tubular device, and cinching the drawstring around the catheter at the sealing pad to couple the tubular device to the catheter.

Abstract: Gastrointestinal bypass devices are described. A gastrointestinal bypass device may comprise a cuff configured to be placed at least partially in an esophagus of the patient, and a sleeve configured to be placed at least partially in a stomach of the patient. In one embodiment, the gastrointestinal bypass device may also comprise a tether coupled to the cuff and/or the sleeve. The tether may be configured to be placed through a fistula between an esophagus and a skin of the patient. The tether may have a length sufficient to extend from the cuff and/or the sleeve to the skin.

Abstract: Devices and methods for gastrointestinal bypass are described. A gastrointestinal bypass device includes a gastrointestinal cuff and a gastrointestinal sleeve. The cuff may be configured to be attached in the esophagus, and may be sufficiently flexible to expand and collapse to conform with the inside of the esophagus to allow the esophagus to function substantially normally. The sleeve is configured to be coupled to the cuff, and may be made of a material that is floppy or flaccid but does not substantially expand radially.

Abstract: A gastrointestinal bypass device for directing food and liquids from an esophagus and/or a proximal portion of a stomach into an intestines is described. The device comprises a receiver, a sleeve, and a device coupling. The receiver may be configured to be positioned in the esophagus and/or the stomach. A proximal portion of the receiver may be configured to open and close to at least partially conform to an inside of the esophagus and/or a proximal portion of the stomach. The receiver may be configured to receive food and liquids from the esophagus and/or a proximal portion of the stomach into a lumen of the receiver. The sleeve may be coupled to a distal portion of the receiver. The sleeve may be configured to be positioned in the stomach and the intestines. The sleeve may have a lumen in communication with the lumen of the receiver. The sleeve may be configured to direct the food and the liquids from the receiver into the intestines.
