Abstract: An embolization device may include a fiber section having a plurality of polymeric electrospun fibers and, optionally, a contrast agent. An embolization device may further include a plurality of fiber sections, wherein each fiber section is separated by a linker. A method of deploying such an embolization device may include inserting the embolization device into a vessel. The method may further include applying an electrical current to one or more of the linkers, applying electrothermal heat to at least a portion of the device, or applying force to at least a portion of a delivery vehicle for the device. A method of manufacturing the device may include electrospinning a fiber section, and processing the fiber section by straining, twisting, heating, or shaping it.

Abstract: Systems and methods of fabricating corrugated electrospun fiber assemblies are disclosed herein. The method can include placing an electrospun fiber scaffold on a corrugation rod, wherein the corrugation rod comprises a helical structure; applying a monofilament fiber about the electrospun fiber scaffold and the corrugation rod from a dispenser as the dispenser is translated longitudinally and the corrugation rod is rotated such that the monofilament fiber is wrapped about the electrospun fiber scaffold at a defined threads per inch (TPI) to form a wrapped electrospun fiber assembly; and longitudinally compressing the corrugated electrospun fiber assembly until it has been compressed from a first length to a second length to form the corrugated electrospun fiber assembly. The corrugated electrospun fiber assemblies can be kink-resistant as compared to conventional electrospun fiber scaffolds. The corrugated electrospun fiber assemblies can be used in, for example, biological applications within a subject.

Abstract: A mandrel for forming a mold may comprise a rod having an outer surface, and a spiral component disposed around the outer surface of the rod, wherein the mandrel may be configured to receive an electrospun fiber. A method of making a kink-resistant electrospun fiber mold may comprise configuring such a mandrel to receive an electrospun fiber, applying a charge to one or more of the rod, the spiral component, and a polymer injection system, and depositing a polymer solution ejected from the polymer injection system onto the mandrel. A mold formed from such a method may comprise an inner wall extending axially, and an outer wall adjacent to the inner wall, having a plurality of axially adjacent, outwardly extending peaks separated by a plurality of valleys.
