Abstract

The present document relates to apparatus and methods for use in the minimally invasive creation of arteriovenous fistulas (AVF). In particular, the present invention relates to the use of catheters to create AVFs, and methods of alignment based on the detection of asymmetric electric fields. The present invention finds particular application in vascular access (VA) in the hemodialysis (HD) population.

Description

technical field [0001] The present invention relates to apparatus and methods for use in the minimally invasive creation of arteriovenous fistulas (AVFs). In particular, the present invention relates to the use of catheters and alignment methods to create AVFs. The invention has particular application in vascular access (VA) in the hemodialysis (HD) population. Background technique [0002] More than half of the million patients with kidney failure requiring hemodialysis in the United States and Western Europe are at significant risk. This risk is due to limitations and performance issues with current methods for dialyzers that are connected to the patient's circulatory system, known as vascular access (VA) sites. Obtaining long-term vascular access that remains patented and infection-free is extremely difficult (see Leermakers et al. (2013); US Dept. Health and Human Services Report (2014); and Al-Jaishi et al. (2014)). [0003] Vascular access can be obtained in one of ...
