Abstract
A device, and related systems and methods, for inserting a marker into a patient's body. The device may comprise a retention mechanism to hold the device in a first, undeployed, state. The device may be inserted into a patient's body in the first state, transitioned by the user into a second state wherein the retention mechanism is overcome, and then transition the device into a third state to deliver a marker to a precise location. The device may then be removed from the patient's body.
Claims20
A system for implanting a marker, the system comprising:
- a marker insertion device comprising:
- a housing coupled to a stylet;
- and
- a trigger coupled to a cannula, the trigger operatively coupled to the housing such that a portion of the stylet is disposed within the cannula,
- wherein the housing comprises a retaining portion to retain the trigger in a first position relative to the housing.
A marker insertion device comprising:
- a housing coupled to a stylet;
- and
- a trigger coupled to a cannula, the stylet slidably disposed within the cannula,
- wherein the housing comprises a retaining portion to retain the trigger in a first position relative to the housing.
A method for implanting a marker within a patient's body, comprising:
- obtaining a marker;
- obtaining a marker insertion device comprising:
- a housing coupled to a stylet;
- and
- a trigger coupled to a cannula, the stylet disposed within the cannula,
- wherein the housing comprises a retaining portion to retain the trigger in a first position relative to the housing;
- inserting the insertion device into the patient's body;
- translating an actuator of the trigger laterally, thereby moving the trigger from the first position to a second position;
- displacing the actuator proximally, thereby moving the trigger into a third position;
- and
- removing the marker insertion device from the patient's body.
