A wide variety of short-term catheters are used in clinical practice to infuse fluids, medications, or other substances, monitor physiologic parameters, and drain organs or other cavities. Interventional radiology catheters, in particular, are widely used to drain various structures and cavities, including the chest cavity, obstructed kidneys, and abscesses, accounting for approximately $200 million in annual revenue. There is an increasing appreciation, however, in the importance of catheter securement. A variety of catheter securement devices are now on the market accounting for about $4 billion in annual revenue.
Currently marketed short-term catheters are not self anchoring, they have been traditionally anchored to the skin with simple tape or other adhesive incorporated into a sterile dressing. Catheter dislodgement leads to increased pain and costs, as well as potentially more serious complications, including the interruption of critical treatments, bleeding, and the influx of air, adversely impacting quality of care. Dislodgement of interventional radiology catheters, in particular, are a major concern and may require another visit to the procedural suite to replace or reposition the catheter. Monitoring catheter patency and reinserting dislodged catheters is labor intensive. Currently marketed short-term catheters are not self anchoring and separate securement devices add complexity and cost to patient care.
NextCath catheters are self-anchoring and do not require suturing, traditional anchoring techniques or costly add-on catheter securement devices. We are initially focusing on interventional radiology catheters which are less commoditized and result in significantly greater risk when dislodged. A proximal helical section of the catheter is advanced through the skin creating a retaining structure just under the skin. This self-anchoring mechanism is applicable to most, if not all, short-term catheters, allowing insertion with standard techniques and the use of simple, clear sterile dressings. It allows the hub of the catheter to be flat and the tubing to emerge parallel to the skin, improving patient comfort and catheter management.
