Hemodialysis access system including subcutaneous port and catheter and associated cleaning apparatus

摘要

This invention is a catheter brush assembly (40) for brush cleaning interior walls of a catheter (22), the assembly including a flexible elongated shaft (42) for movement lengthwise in the catheter, and a brush (44) mounted on the shaft proximate a distal end of the shaft adapted to engage to interior wall of the catheter to effect the brush cleaning. At least one of the distal ends of the shaft (49), a distal end of the brush (50) are rounded for non-traumatic contact with the wall of the catheter, and a wall of a blood vessel in which the catheter is disposed.
