Embodiment Construction

[0101] The present technology provides devices, systems, and methods for sheathing and / or re sheathing intravascular deliverable therapeutic devices. Although many embodiments are described below regarding devices, systems, and methods for removing clot material / treating embolism (such as cerebral embolism), the sheathing tool of the present technology can be used to deliver any intravascular, expandable Reinstall the sheath of the treatment device. Other applications and other embodiments than those described herein are also within the scope of the present technology. For example, the sheathing tool of the present technology can be used to remove embolism from body cavities other than blood vessels (such as the digestive tract, etc.) and / or can be used to remove embolism from blood vessels outside the brain (such as lung blood vessels, in The blood vessels in the legs, etc.) can be used together with devices that remove embolism. In addition, the sheathing tool of the presen...

Abstract

Devices for loading intravascular treatment devices into a sheath and associated systems and methods are disclosed herein. A sheathing tool may include, for example, a first channel extending to a first opening, the first channel configured to receive a treatment device in a constrained state therethrough. The treatment device may include an elongated member and a first element and a second element at a distal region of the elongated member. The second channel extending to a second opening, the second opening surrounded by a sidewall and configured to receive the treatment device in the constrained state therethrough, wherein the second opening is spaced apart from the first opening by a gap, and wherein a length of the gap is great enough to allow the first element to self-expand over thesidewall while the second element generally maintains its diameter in the constrained state while crossing the gap.

Description

Technical field [0001] The present technology generally relates to sheathing tools and associated systems and methods. Some embodiments of the present technology relate to devices for loading endovascular treatment devices into sheaths. Background technique [0002] Many medical procedures use one or more medical devices to remove obstructions (such as clot material) from body cavities, vessels, or other organs. The inherent risk in this type of surgery is that moving or otherwise interfering with the obstruction can potentially cause additional injury when the obstruction or fragments thereof are removed from the acquisition device. If all or part of the obstruction leaves the device and flows downstream, it is highly likely that the free material will remain in the smaller and more tortuous anatomy. In many cases, the physician will no longer be able to use the same acquisition device to remove the obstruction again because the device may be too large and / or unable to move to...
