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.
Claims15
A method to control fluid flow in an obturator assembly, the obturator assembly comprising an obturator movably positioned within a lumen of a catheter, the method comprising:
- moving the obturator from a proximal position to a distal position, wherein in response to the obturator being in the proximal position, a distal end of the obturator limits fluid flow through the lumen, wherein in response to the obturator being in the distal position, the distal end of the obturator provides a fluid flow path through the lumen of the catheter,
- wherein the obturator assembly comprises a hub and a locking collar operatively coupled to the hub, wherein the locking collar is configured to lock the obturator in the distal position, wherein the locking collar comprises a tab configured to depress to selectively interfere with a depression formed in the obturator in the distal position.
An obturator assembly, comprising:
- a catheter, comprising a distal end and a proximal end, the catheter forming a lumen extending between the distal end of the catheter and the proximal end of the catheter;
- a hub forming a central passage;
- and
- an obturator extending distally from the hub, wherein the obturator is movable from a proximal position to a distal position, wherein in response to the obturator being in the proximal position, a distal end of the obturator limits fluid flow through the lumen, wherein in response to the obturator being in the distal position, the distal end of the obturator provides a fluid flow path through the lumen of the catheter;
- and
- a locking collar operatively coupled to the hub, wherein the locking collar is configured to lock the obturator in the distal position, wherein the locking collar comprises a tab configured to depress to selectively interfere with a depression formed in the obturator in the distal position.
