A device and method is provided for a suction tool combined with an optical probe. A suction device is provided having a tip with a hollow tubular body, a plurality of optical fibers embedded in the tip and a concentric ring attached to the tip, wherein the ring end has an inner beveled reflective surface opposing the optical fibers. A method is provided for optically measuring tissue in a medical procedure comprising suctioning a tissue using a suction device, sending optical signals along optical fibers through the suction device; directing the signals from the optical fibers onto the tissue using a beveled surface; receiving optical signals from the tissue in optical fibers via the beveled reflective surface; measuring the received optical signals in a spectrometer or detector; and releasing, resecting or ablating the tissue through the suction device.

The methods and devices disclosed herein promote temporal control of balloon inflation patterns. The devices include a covering for a portion of the balloon that compresses the balloon portion during the inflation process. This enables the distal portion of a balloon to be inflated prior to the proximal portion of a balloon, creating a tapered shape at lower inflation pressures. This is especially useful during transvascular implantation procedures, as it prevents dislodgement of an implant mounted on the balloon. As inflation continues, pressure exerted on the balloon by the covering is overcome such that the proximal region of the balloon inflates, forming a shape with generally straighter sides than the tapered shape, thereby expanding the cardiovascular device.

Method of endovascular intervention in neurovascular anatomy of a patient including deploying an anchor of a tethering device in an anchoring vessel of a neurovascular anatomy, the anchor coupled to a tether extending proximally from the anchor. Method includes advancing a guide-sheath over the tether of the tethering device anchored in the anchoring vessel and attached to the tether, the guide-sheath includes at least one lumen and a distal opening from the lumen. Method includes advancing a treatment device through the lumen of the guide-sheath and out the distal opening from the at least one lumen and through an entrance of a target intracranial vessel, and deploying the treatment device at a treatment site within the target intracranial vessel without a combined therapy of two or more anti-platelet therapeutic agents during a peri-procedural period. Related systems, devices, and methods are disclosed.
