Systems, apparatus, and methods for treating medication refractory epilepsy are disclosed. In one embodiment, a method of treating epilepsy is disclosed comprising detecting, using a first electrode array coupled to a first endovascular carrier, an electrophysiological signal of a subject. The method further comprises analyzing the electrophysiological signal using a neuromodulation unit electrically coupled to the first electrode array and stimulating an intracorporeal target of the subject using a second electrode array coupled to a second endovascular carrier implanted within a part of a bodily vessel superior to a base of the skull of the subject.

A method for implanting a stent includes contracting a self-expanding/forcibly-expanding stent of a shape-memory material set to a given shape to a reduced implantation size with a delivery system having drive wires. The stent has a selectively adjustable assembly with adjustable elements operatively connected to the drive wires such that, when the adjustable elements are adjusted by the drive wires, a configuration change in at least a portion of the self-expanding stent occurs. The contracted stent is inserted into a native annulus in which the stent is to be implanted. The drive wires are rotated with the delivery system to forcibly expand the stent into the native annulus. While rotating the drive wires, a torque applied to the drive wires is determined with the delivery system. Rotation of the drive wires is stopped based upon a value of the determined torque.

An implantable ureteral stent for implanting in the ureter comprising a first end for placing in the renal pelvis and a second end for placing in the bladder, each said end including a pressure sensor arranged to measure urinary pressure. Each pressure sensor can include an electronic circuit with electronic components and a substrate for receiving the electronic circuit and electronic components, wherein said substrate is a flexible membrane. The flexible membrane can be a sleeve surrounding the stent or the flexible membrane can be a flexible tube that is part of a thin tube that forms the stent, in particular the flexible membrane may have a thickness of 80-150 μm. The electronic components can be connected by wire-bonding. Each pressure sensor can have a flexible PCB having soldered electronic components. A manufacturing method is disclosed to make said implantable ureteral stent.

Each pressure sensor can include an electronic circuit with electronic components and a substrate for receiving the electronic circuit and electronic components, wherein said substrate is a flexible membrane. The flexible membrane can be a sleeve surrounding the stent, or the flexible membrane can be a flexible tube that is part of a thin tube that forms the stent, in particular the flexible membrane can have a thickness of 80-150 μm. A manufacturing method is disclosed for providing said implantable biliary or pancreatic stent.

In part, the disclosure relates to systems and methods of detecting struts in a blood vessel. In one embodiment, an intravascular data collection system and an intravascular data collection probe are used. An exemplary method may include one or more of the following steps converting an image of a blood vessel into an image mask, the image includes struts of a bioresorbable scaffold; inverting the image mask to create an inverted image mask, detecting an insular group of bright/signal containing pixels; and filtering the insular group of bright/signal containing pixels using one or more morphological filters to identify candidate struts; and validating the candidate struts to identify one or more struts of the bioresorbable scaffold.
