Abstract
This document relates to the apparatus and methods used in the minimally invasive creation of arteriovenous fistula (AVF). In particular, the invention relates to the creation of an AVF using catheters and an alignment methodology that is based upon detection of asymmetric electric fields. The invention finds particular application in vascular access (VA) in the hemodialysis (HD) population.
Claims17
A method of connecting two adjacent vessels within the body of a patient, said method comprising the steps of:
- a) introducing a first source device into a first vessel, the first device comprising at least one signal electrode for generating an asymmetric electric field;
- b) introducing a second sensing device into a second vessel, the second device comprising at least one detector for detecting the asymmetric electric field;
- c) aligning the first and second device relative to each other based on the asymmetric electric field generated by the first device that is detected by the detector on the second device;
- d) forming a conduit between the first vessel and the second vessel;
- and
- e) removing the first and second devices to leave the first and second vessels connected via the conduit.
