## Abstract

A device (100) for performing vascular access of the arteriovenous fistula type in a dialysis treatment comprising a first vertical branch (1), arterial, and a second vertical branch (2), venous, both branches being hollow and arranged parallel to each other while their lumens communicate via a horizontal branch (7). The device (100) comprises at least two blood flow interception means (10, 11) in which the first interception means (10) is arranged on the horizontal branch (7) and the second interception means (11) is disposed in a distal portion (2′) of the second vertical branch (2), venous.

## Claims

### Claim 1

A device (100) for performing vascular access of the arteriovenous fistula type in a dialysis treatment comprising a first vertical branch (1), arterial, and a second vertical branch (2), venous, both branches being hollow and arranged parallel to each other while their lumens communicate via a horizontal branch (7); said device (100) comprises at least two blood flow interception means (10, 11) in which the first interception means (10) is arranged on the horizontal branch (7) and the second interception means (11) is disposed in a distal portion (2 ‘) of the second vertical branch (2), venous.

### Claim 2 (depends on 1)

The device (100) according to claim 1, further comprising a third diaphragm (12) arranged in a distal portion (1’) of the first vertical branch (1), arterial.

### Claim 3 (depends on 1)

The device (100) according to claim 1, wherein the distal portion (1′) of the first vertical branch (1), arterial, is connected to a distal arterial stump (4) and a proximal portion (1″) of the first vertical branch (1), arterial, connects to a proximal arterial stump (3), while the distal portion (2′) of the second vertical branch (2), venous, connects to a distal venous stump (6) and a proximal portion (2″) of the second vertical branch (2), venous, connects to a proximal venous stump (5).

### Claim 4 (depends on 1)

The device (100) according to claim 1, wherein said device (100) is entirely made of biocompatible material.

### Claim 5 (depends on 1)

The device (100) according to claim 1, further comprising electric supply means and actuator means configured for regulating the blood flow interception means (10, 11).
