Abstract
An obturator assembly includes an obturator positionable within a lumen of a device and movable within the lumen between a first position and a second position. The obturator includes a distal tip portion, wherein, with the obturator in the first position, the distal tip portion limits fluid communication through the lumen and, with the obturator in the second position, the distal tip portion provides fluid communication through the lumen.
Claims17
An obturator assembly, comprising:
- a hub forming a central passage;
- a catheter having a distal end and an opposing proximal end, the catheter including a small-bore connector at the proximal end coupled to the hub, the catheter forming a lumen extending between the distal end and the proximal end of the catheter, the lumen in fluid communication with the central passage;
- an obturator movably positioned within the lumen, the obturator movable between a first position and a second position, the obturator including a distal end having a tip portion, wherein, with the obturator in the first position, the distal end of the obturator limits fluid flow through the lumen and, with the obturator in the second position, the distal end of the obturator provides a fluid flow path through the lumen;
- and
- a locking collar operatively coupled to the hub, the locking collar configurable in a locked configuration to prevent movement of the obturator within the lumen and in an unlocked configuration to allow movement of the obturator within the lumen, wherein, in the locked configuration, the locking collar is configured to prevent movement of the obturator within the lumen with the obturator in the first position or the second position, wherein the locking collar comprises a tab configured to selectively interfere with a depression formed in the obturator with the locking collar in the locked configuration.
