NON-THROMBOGENIC DEVICES FOR TREATING EDEMA
20210378676 · 2021-12-09 ·

The invention provides intravascular devices for treating certain medical conditions such as edema without causing thrombosis. The intravascular devices of the disclosure include non-thrombogenic surfaces that improve blood compatibility by reducing device-related thrombus formation and inflammatory reactions. The non-thrombogenic surfaces may include surface topographies (e.g., surface roughness) and modified chemistries (e.g., coatings and/or treatments), which prevent thrombosis by reducing local shear forces and inhibiting adhesion of blood clotting factors.

HYDROGEL CO-INJECTION AND REAL-TIME OPTO-ELECTROMAGNETIC MODIFICATION DEVICE FOR TUNABLE IN-VIVO DELIVERY

Described herein are systems, devices and methods that enable dynamic modification of the physicochemical properties of a hydrogel during its in vivo formation and delivery by a catheter. In some example embodiments, an extended endoluminal hydrogel delivery device is employed for delivering a hydrogel within given body cavity, such as within the lumen of a blood vessels. In some example embodiments, a hydrogel precursor, as a non-viscous liquid, is injected through an intravascular catheter and crosslinking of the hydrogel precursor is initiated within a distal region of the catheter. The crosslinking process is controlled, by a control means associated with a distal region of the catheter, to control or modify one or more properties of the hydrogel. The properties may be controlled such that a hydrogel is suitable to embolize the specific target or deliver drugs or other materials beneficial to the site.

DEVICES AND METHODS FOR ASPIRATION OF THROMBUS

An aspiration catheter for removing clot from a blood vessel includes a catheter body having a scaffold extending distally from a distal end of the body. An aspiration lumen runs from the distal end to a proximal end of the body, and a central clot-receiving passage in the scaffold is contiguous with the aspiration lumen of the catheter body. A vacuum-resistant membrane covers the scaffold and establishes a clot aspiration path from a distal end of the scaffold to a proximal end of the aspiration lumen, in the catheter body so that applying a vacuum to the proximal end of the aspiration lumen can draw clot into the central clot-receiving passage. The scaffold may have a comical configuration, a cylindrical configuration, or a combination thereof, and at least a distal portion of the scaffold is radially expandable from a delivery configuration to an extraction configuration.
