Abstract

Hemostasis valves and methods for making and using hemostasis valves are disclosed. An example method for assembling a hemostasis valve may include positioning a plunger along a threaded proximal end region of a main body. The threaded proximal end region may include one or more threads and an axial slot extending through the one or more threads. The method may also include advancing the plunger along the threaded proximal end region to a position where a proximal end of the plunger is disposed distally of at least a portion of the one or more threads and disposing a nut adjacent to the threaded proximal end region. The method may also include aligning an alignment tab of the nut with the axial slot, engaging the nut with the one or more threads while the alignment tab is aligned with the axial slot, and rotating the nut 45-270°.
