摘要： An endoluminal punch and introducer sheath are described wherein the endoluminal punch comprises a guidewire lumen through which a user is capable of placing a guidewire. The endoluminal punch system further comprises a mechanism affixed to the hub which is capable of controlling the axial positioning of the guidewire relative to the endoluminal punch distal end. The control mechanism can be released so that the endoluminal punch can be removed from a patient while retaining the guidewire in place within the patient. The endoluminal punch introducer, including a sheath and dilator, can comprise energy emitting electrodes or transducers for cutting larger size holes in stubborn (friable, scarred, or fibrotic) tissue. In other embodiments, the endoluminal punch can comprise a guidewire or stylet, wherein the guidewire or stylet is capable of emitting energy to cut through tissue.

摘要： A transvascularly placed steerable microcatheter, further including internal steerability and the ability to articulate in a direction at right angles to its longitudinal axis at or near its distal end. The steerable microcatheter is generally fabricated from stainless steel, nitinol, or other metal and includes an outer tube, an inner tube, hub structures, and a distal articulating region. The steerable microcatheter can be advanced through a body lumen in its straight configuration and then be selectively articulated or curved to permit negotiation of tortuous curvature. The microcatheter is especially suited to robotic or powered control applications with user intervention or using artificial intelligence (AI).
