Spring Action Medical Device
First Claim
Patent Images
1. A medical device, comprising:
- a distal tip;
a spring; and
a hammer component disposed between the distal tip and the spring;
wherein the spring is configured to provide a force when released from a loaded state to propel the hammer component in a distal direction to strike the distal tip.

Abstract
A spring action medical device includes a spring that may propel a hammer component in a distal direction when the spring is released from a loaded state. When propelled forward by the spring, the hammer component makes contact with a distal tip of the medical device. The distal tip may then transfer a force to an external object, such as an occlusion in a body lumen.

15. A medical device, comprising:
-
a body portion; a distal tip disposed at a distal end of the body portion; a support structure on an inner surface of the body portion; a hammer component; a spring disposed between the hammer component and the support structure; and a trigger wire coupled with the hammer component in a configuration where movement of the trigger wire in a proximal direction relative to the body portion retracts the hammer component and compresses the spring into a loaded state between the hammer component and the support structure; wherein the spring is configured to provide a force when released from the loaded state to propel the hammer component in a distal direction relative to the body portion to strike the distal tip.

16. A method of using a medical device, comprising:
-
placing a spring of the medical device in a loaded state by retracting a trigger wire of the medical device; positioning a distal tip of the medical device to abut an occlusion in a body lumen or to be within a distal tip movement range of the occlusion in the body lumen; and releasing the spring from the loaded state to propel a hammer component of the medical device in a distal direction to strike the distal tip and transfer a force from the distal tip to the occlusion. - View Dependent Claims (17, 18, 19, 20)
