Abstract
Medical instruments and methods of using the instruments are described. In some embodiments, a medical instrument includes a housing, a stylet having a portion in the housing, a movable first member in the housing, the movable member being connected to the stylet, and a second member located in the housing to reduce movement of the first member. The second member is configured to change movement of the first member from a first direction to a second direction different than the first direction.

A medical instrument, comprising:
- a housing;
- a stylet having a portion in the housing;
- a movable first member in the housing, the movable first member being connected to the stylet;
- a stop in contact with and extending a first distance from a bottom wall of the housing in a first direction;
- and
- a second member in contact with and extending axially from the stop, the second member in contact with and extending a second distance from the bottom wall of the housing in the first direction, the second distance being less than the first distance, the second member configured to change movement of the first member from a linear first direction of movement of the first member to a second direction of movement of the first member before the first member contacts the stop;
- wherein the second direction of movement of the first member includes a component transverse to the first direction of movement of the first member.
