INFILTRATION CANNULA
First Claim
1. An infiltration cannula for use in an infiltration procedure, the infiltration cannula comprising:
- a tubular needle comprising;
a proximal end;
a distal end; and
a plurality of apertures disposed in a pattern about the distal end, the apertures configured to infiltrate fluid into subcutaneous tissue of a patient; and
a hub configured to be held by a person performing the infiltration procedure, the hub having a first end and an opposing second end, the first end being attached to the proximal end of the tubular needle, the second end comprising a connector configured to connect to an input source for receiving the fluid to be infiltrated into the subcutaneous tissue of the patient, the fluid flowing from the connector, through the hub and into the tubular needle.

Abstract
An infiltration cannula and method of using the infiltration cannula during an infiltration procedure are disclosed herein. The infiltration cannula includes: a tubular needle and a hub. The tubular needle has a proximal end and a distal end. The tubular needle also has a plurality of apertures disposed in a pattern about the distal end. The apertures are configured to infiltrate fluid into the subcutaneous tissue of a patient. The hub is configured to be held by a person performing the infiltration procedure. The hub has a first end and an opposing second end. The first end is attached to the proximal end of the tubular needle and the second end includes a connector configured to connect to an input source for receiving the fluid to be infiltrated into the subcutaneous tissue of the patient. The fluid flows from the connector, through the hub and into the tubular needle.
