摘要：
A delivery catheter assembly (400) is disclosed in which a tip protector sleeve (300) is locked onto an elongated catheter sheath (404) and slideable over a length of the elongated catheter sheath between a proximal - stop position (402) and a distal -stop position (408) along the elongated catheter sheath. The present invention generally provide assemblies and methods of inserting a delivery catheter into a working channel of an endoscope, such as a hysteroscope system for accessing a female reproductive system. Advancement of the delivery catheter system within the uterus and the fallopian tubes is usually facilitated by distending the uterus with a distention fluid, such as saline, and viewing the placement with the hysteroscope system. During the proceedure fluid can spray onto the physician or physician&rsquo；s assistant. The amount of fluid spray-back can be significant depending on the distention fluid pressure during the procedure. The delivery catheter assembly may include an interference stop which determines the distal-stop position and prevents the tip protector sleeve from sliding off of the distal end of the elongated catheter sheath. The tip protector sleeve may additionally incorporate a sealing valve to reduce the amount of fluid spray-back and leakage associated with inserting the delivery catheter assembly into the working channel of a hysteroscope system.
