A catheter with a removable sleeve designed to remove debris that accumulates on the walls may be utilized in drainage catheters but has broad applications in indwelling tubes.
- Sleeve removal is functionally anti-occlusion, which has benefits in:
- Decreased complications from catheter occlusion, including infection.
- Overall, expected improved clinical outcomes from decreased emergent exchanges.
- Decreased healthcare expenditures.
- Sleeve-removal design can be incorporated in any tubular catheter assembly, notwithstanding urinary catheters including Foley catheters, suprapubic catheters, abscess drainage catheters, biliary catheters, and vascular access catheters.
Percutaneous nephrostomy (PCN) represents one instance of the application of this technology, wherein at least 105,000 cases of PCN placement take place annually. Unfortunately, PCN catheters are prone to biofilm development and urine mineral deposits which can lead to catheter obstruction and subsequent clinical infection. The enclosed technology represents a catheter assembly with a removable sleeve, atop which biofouling (biofilm accumulation, encrustation, etc) occurs. When such biofouling leads to catheter dysfunction, the provider has the option to remove the sleeve and insert another unused sleeve. This sleeve exchange can take place at regular intervals and obviates the need for catheter exchanges as the removable sleeve, rather than the catheter itself, is removed. This invention will compete in the global catheter market, which is expected to reach $34.489 billion by 2023 from $27.24 billion in 2018 at a CAGR of 4.8% (BCC Research HLC019H). The aging population being a contributing factor to this increase in value.
The enclosed technology represents a catheter assembly with a removable sleeve, atop which biofouling (biofilm accumulation, encrustation, etc.) occurs. When such biofouling leads to catheter dysfunction, the provider has the option to remove the sleeve and insert another unused sleeve. The sleeve covers the inner lumen of the catheter. The catheter assembly includes a (1) tube and (2) a sleeve that can be inserted and removed from within the inner lumen of the tube. At some point along the removable sleeve, the sleeve is geometrically shaped to out-pouch and fit within a mating geometric shape within the catheter tube. The sleeve outpouching will lock into place on insertion and with enough force directed away from the catheter in the long axis of the catheter, it will overcome the locking mechanism to be removed from the catheter lumen. Thereafter, another sleeve can be inserted.
