Abstract: A tool for measuring a density of a clot within a vessel of a patient includes a first depth indicator wire disposed in the lumen of the flexible catheter. The second end of the first depth indicator wire extends distally beyond the second distal end of the catheter. A chamber has a piston disposed within the chamber. The proximal end of the first depth indicator wire is connected to the distal side of the piston. A spring is disposed within the chamber. A second depth indicator wire is connected to the proximal side of the piston. A proximal end of the second depth indicator wire extends proximally beyond the proximal end of the chamber and has a plurality of depth indicator markers on an exterior surface thereof.

Abstract: Advanced systems for endoscopic visualization with illumination for color visualization and advanced visualization. A device for connecting optical and electrical components of an imaging system includes a first fiber optic ferrule dedicated to receiving a first emission of electromagnetic radiation emitted by a first source, and a second fiber optic ferrule dedicated to receiving a second emission of electromagnetic radiation emitted by a second source. The device includes a data connection component configured to receive bidirectional data communications. The imaging system is such that the first source is tuned to pulse a different waveband of electromagnetic radiation than the second source.

Abstract: A method of delivering a catheter to a location of interest in the vasculature, the method including positioning a self-expanding sheath within a lumen of the catheter; advancing the catheter and the self-expanding sheath in tandem over a guidewire; and distally moving a distal end of the self-expanding sheath out from the lumen of the catheter thereby causing the self-expanding sheath to move from a collapsed state within the catheter to an expanded state outside the catheter, wherein when the self-expanding sheath is in the expanded state both the self-expanding sheath and the catheter are distally advanceable in tandem.

Abstract: Devices can generally include a fan portion for occluding an aneurysm neck, a channel orifice opening in the fan portion, and an agent channel for delivering a coagulating agent through the orifice into the aneurysm. Devices can be delivered through a catheter to the aneurysm, the fan portion can expand to occlude the aneurysm neck, and coagulating agent can be injected into the aneurysm. During injection of the coagulating agent, the fan portion can inhibit the coagulating agent from exiting the aneurysm. After injection of the coagulation agent, the fan portion can collapse and the device can be extracted from the patient.

Abstract: Systems and methods for delivering a catheter to a location of interest in the vasculature, the method including selectively positioning a guidewire at the location, positioning a self-expanding sheath within a lumen of the catheter, advancing the catheter and the self-expanding sheath in tandem over the guidewire, and distally moving a distal end of the self-expanding sheath out from an inner lumen of the catheter thereby causing the self-expanding sheath to move from a collapsed state within the catheter to an expanded state outside the catheter.
