What is the Needle Injection Catheter?
NIC is a percutaneous device intended for the injection of agents or stem cells into the myocardium.
How does it work?
The device is inserted until the distal tip is positioned at the target location. The needles are deployed and adjusted to the appropriate length for insertion. Once the needles are positioned in place, the treating agent can be steadily injected in multiple sites of the tissue.
Commercially available needle catheter systems consist of only a single needle which means that multiple injections have to be performed. Consequently, NIC's three-needle design increases injection efficiency and reduces the length of the procedure.
The procedure is controlled by an elegant and simple handle that fits easily into one’s palm. The operation of NIC consists of a series of steps that are performed by using various components of the handle.
The distal tip of the catheter contains three curved needles. The tip and the needles are radiopaque and therefore provide good visibility for a safe and steady injection.
The injection procedure with the NIC is simple and can be repeated with minimal variation. The NIC minimizes the length of the procedure and improves the efficiency of the injection.
The Problem with Single-needle Injection Catheters
Needle injection devices available on the market contain a single needle that requires multiple injections. This single-needle design poses the risk of perforating targeted tissues and lowering the retention of injected agents.
In addition, single-needle designs lack stability and can easily slide out during the injection, which decreases the devices’ efficiency and safety.
The NIC is intended for the injection of agents or stem cells into the myocardium. The device contains three outwardly curved needles designed to provide greater stability and safety during the injection. This curved design better secures the needles within the tissue and makes a perforation of the tissue almost impossible. NIC's multiple needles require fewer injections, which in turn shortens the duration of the procedure and allows higher stem cell retention in comparison to single-needle designs.
