Abstract: Provided herein are catheter assemblies with detachment means for delivering implants. A method for coil embolization using a catheter includes: inserting a catheter into a patient intravenously or intraarterially; navigating the catheter to an aneurysm, the catheter defining an outer wall; placing a tip of the catheter at an opening of the aneurysm; delivering into the aneurysm, via pusher wire, through a lumen of the catheter, a coil; determining a user defined detachment point at which a distal coil segment of the coil should be detached from the coil; aligning the user defined detachment point of the coil with a designated detachment zone at the tip of the catheter; and toggling a laser source connected to the embedded optical fiber, thereby detaching the distal coil segment from the coil via an embedded laser beam emitted from the optical fiber at the designated detachment zone at the tip of the catheter.

Abstract: Techniques and mechanisms for providing anisotropic etching of a metallization layer of a substrate. In an embodiment, the metallization layer includes grains of a conductor, wherein a first average grain size and a second average grain size correspond, respectively, to a first sub-layer and a second sub-layer of the metallization layer. The first sub-layer and the second sub-layer each span at least 5% of a thickness of the metallization layer. A difference between the first average grain size and the second average grain size is at least 10% of the first average grain size. In another embodiment, a first condition of metallization processing contributes to grains of the first sub-layer being relatively large, wherein an alternative condition of metallization processing contributes to grains of the second sub-layer being relatively small. A grain size gradient across a thickness of the metallization layer facilitates etching processes being anisotropic.

Abstract: Isotropic (amorphous) elastomers and methods of preparation are described. The isotropic elastomer may include a first monomer having an alkene functionality and a second monomer having a thiol functionality. The first monomer may be a liquid crystal monomer and the second monomer may be an isotropic monomer. Unlike polydomain LCEs, the isotropic elastomers may rapidly recover after deformation and have increased toughness relative to conventional elastomers prepared from wholly isotropic precursors.

Abstract: The systems and methods described herein use at least one etchant and at least one photochemically active material in conjunction with electromagnetic energy applied simultaneous with the etchant and photochemically active material during the etching process. The interaction between the electromagnetic energy and the photochemically active material preferentially increases the etch rate in a direction along the axis of incidence of the electromagnetic energy, thereby permitting the anisotropic formation of voids within the semiconductor substrate. These anisotropic voids may be more closely spaced (i.e., arranged on a tighter pitch) than the isotropic voids produced using conventional etching technologies. By placing the voids in the semiconductor substrate on a tighter pitch, greater component density may be achieved.
