MEDICAL DEVICE WITH ONE-WAY ROTARY DRIVE MECHANISM
First Claim
1. A method, comprising:
- inserting a distal end portion of an elongate member into a biological body;
after the inserting, manually actuating an actuation mechanism to produce translational motion of a drive element; and
converting the translational motion into rotational movement of the distal end portion of the elongate member.

Abstract
Apparatuses and methods for accessing and disrupting a tissue are disclosed herein. In one embodiment, a method includes inserting a distal end portion of an elongate member into a biological body. After inserting the elongate member, an actuator is manually actuated to produce translational motion of a drive element. The translational motion is converted into rotational movement of the distal end portion of the elongate member. In one embodiment, an apparatus includes an elongate member having a tissue interaction member at a distal end portion that is configured to be inserted within a biological body. A conversion mechanism is coupled to the elongate member and includes a drive element. An actuator is coupled to the conversion mechanism and is configured to cause translational motion of the drive element. The conversion mechanism is configured to convert the translational motion of the drive element into rotational motion of the elongate member.

22. An apparatus, comprising:
-
a sheath; an elongate member movably disposed within a lumen of the sheath; an expandable member disposed at a distal end of the elongate member; a conversion mechanism configured to rotate the elongate member; and an actuator coupled to the sheath, the actuator configured to translate the sheath between a first position in which the expandable member is in a collapsed configuration disposed within a lumen of the sheath and a second position in which the expandable member is in an expanded configuration disposed outside of the lumen of the sheath, the expandable member configured to disrupt tissue within a biological body when the expandable member is in the expanded configuration and disposed outside the lumen of the sheath and within the biological body. - View Dependent Claims (23, 24, 25, 26)
