摘要

Peripheral arterialization devices and methods of using the same. In an exemplary embodiment of a catheter for facilitating venous arterialization of the present disclosure, the catheter comprises an elongated body extending from a proximal end to a distal end and having a lumen defined therethrough along a longitudinal length of the elongated body, the elongated body configured to attach to a graft at or near the proximal end of the elongated body and further configured to permit fluid to flow through the graft, through the lumen, and out of one or more apertures defined within the elongated body at or near the distal end to facilitate venous arterialization upon at least partial implantation of the catheter into a vein of a patient.

1. A catheter for facilitating venous arterialization, comprising:
an elongated body extending from a proximal end to a distal end and having a lumen defined therethrough along a longitudinal length of the elongated body, the elongated body configured to attach to a graft at or near the proximal end of the elongated body and further configured to permit fluid to flow through the graft, through the lumen, and out of one or more apertures defined within the elongated body at or near the distal end to facilitate venous arterialization upon at least partial implantation of the catheter into a vein of a patient; wherein the catheter further comprises one or more nodes defined along the longitudinal length of the catheter, the one or more nodes configured to at least partially occlude the vein when at least part of the catheter is implanted therein; and wherein a first node of the one or more nodes is located proximal to the one or more apertures and has a first resorption rate, wherein a second node of the one or more nodes is located proximal to the first of the one or more nodes and has a second resorption rate, wherein the first resorption rate is faster than the second resorption rate.
