A rigidizing device includes a plurality of layers and an inlet between the elongate flexible tube and the outer layer and configured to attach to a source of vacuum or pressure. The rigidizing device is configured to have a rigid configuration when vacuum or pressure is applied through the inlet and a flexible configuration when vacuum or pressure is not applied through the inlet.

Dynamically rigidizing composite medical structures

A rigidizing device includes an elongate flexible tube having a lumen extending therethrough, a variable stiffness layer, a bladder layer configured to push against the variable stiffness layer when pressure is applied, and a hemostasis valve integrated at a proximal end of the elongate flexible tube in fluid communication with the lumen wherein the rigidizing device is configured to change between a flexible configuration and a rigid configuration in which the bladder layer limits the plurality of strand lengths from moving relative to each other when pressure is applied.

Rigidizing overtube with hemostasis valve

A rigidizing overtube includes an elongate flexible tube, one or more mounting elements attached to the flexible tube, and a plurality of engagers connected to the one or more mounting elements. The rigidizing overtube has a flexible configuration in which the plurality of engagers are configured to move relative to other engagers to accommodate bending of the flexible tube. The rigidizing overtube also has a rigid configuration in which the plurality of engagers are fixed relative to other engagers to prevent the flexible tube from bending.

Dynamically rigidizing overtube

Method of performing one or more procedures within a patient's vasculature using a rigidizing device. The rigidizing device may be inserted through the patient's vasculature in a flexible configuration to a target region, and rigidized to form a stable base from which one or more procedures may be performed. Examples of procedures that may be performed include removing or bypassing an occlusion, placing a stent, mitral valve repair, access and/or treatment of chronic total occlusions, etc.

Methods of performing vascular procedures using a rigidizing device

A device for distending a body lumen for enhanced visualization with a capsule endoscope includes a plurality of struts configured to extend from the capsule endoscope, a retention mechanism configured to attach the plurality of struts to the capsule endoscope, and a trigger configured to release the retention mechanism.

Device and method for enhanced visualization of the small intestine

A rigidizing device includes an elongate flexible tube, a braid layer positioned over the elongate flexible tube, an outer layer over the flexible tube and the braid layer, and an inlet between the elongate flexible tube and the outer layer and configured to attach to a source of vacuum or pressure. The braid layer has a plurality of strands braided together at a braid angle of 5-40 degrees relative to a longitudinal axis of the elongate flexible tube when the elongate flexible tube is straight. The rigidizing device is configured to have a rigid configuration when vacuum or pressure is applied through the inlet and a flexible configuration when vacuum or pressure is not applied through the inlet. The braid angle is configured to change as the rigidizing device bends when the rigidizing device is in the flexible configuration.
