摘要： A bifurcated catheter and methods of use are disclosed herein. The bifurcated catheter can include a fixed flat wire that is configurable as a stabilization wire. The bifurcated catheter can be configured to improve the initial access and directability by application of a pull force to the stabilization wire, in addition to a push force from the proximal end of the bifurcated catheter. The stabilization wire is anchored once the bifurcated catheter is positioned. The anchored, bifurcated catheter provides stability and pushability to assist the procedural catheter in traversing the tortuous peripheral vasculature.

摘要： A device suitable for use in a body lumen and comprises an elongated control member having a distal and a proximal end, and a radially expansible member disposed at or near the distal end and adapted for collection and/or shearing of matter (i.e. thrombus) from a wall of the body lumen (i.e. a vein or an artery). The radially expansible member has a proximal end and a distal end and is adjustable between a contracted orientation and an expanded orientation. The elongated control member comprising a proximal arm connected at or adjacent to the proximal end of the radially expansible member and a distal arm connected at or adjacent to the distal end of the radially expansible member such that movement of one arm relative to the other arm effects adjustment of the diameter or radial strength of the radially expansible member. The device comprises a control mechanism operatively connected to both arms and adapted to provide resistance to the movement of one arm relative to the other. The control mechanism may be a biasing means, a brake means, or both.

摘要： The present technology relates to systems and methods for removing a thrombus from a blood vessel of a patient. In some embodiments, the present technology is directed to systems including an elongated catheter having a distal portion configured to be positioned within the blood vessel of the patient, a proximal portion configured to be external to the patient, and a lumen extending therebetween. The system can also include an imaging element at the distal portion, an illumination source at the distal portion, a capture element at the distal portion and configured to engage the thrombus, a fluid delivery mechanism within the lumen and configured to apply fluid to (1) at least partially fragment the thrombus and (2) provide an optical path for the imaging element, and an aspiration mechanism fluidly coupled to the lumen and configured to aspirate the fragmented thrombus.
