Abstract
A site marker deployment device includes a housing defining a first portion, an outer cannula at least partially interposed within the first portion and having a proximal end and a distal end defined by an outer cannula aperture, an inner member at least partially interposed within the outer cannula, a first biasing portion, a second biasing portion, wherein the second biasing portion will selectively urge the outer cannula to move proximally relative to the inner member, and a site marker selectively disposed within the outer cannula adjacent the inner member, near the distal end of the outer cannula. The first biasing portion will selectively urge a site marker at least partially within the outer cannula.
Claims21
A site marker deployment device, comprising:
- a housing defining a first portion;
- an outer cannula at least partially interposed within the first portion and having a proximal end and a distal end defining an outer cannula aperture;
- an inner member at least partially interposed within the outer cannula;
- a first actuator configured to at least partially release a first biasing portion to thereby selectively retract a site marker from outside of the outer cannula to at least partially within the outer cannula, such that the site marker is retained at least partially within the outer cannula;
- a second biasing portion configured to selectively urge the outer cannula to move proximally relative to the inner member and the site marker.
A method of assembling a deployment device, comprising:
- interposing a first member at least partially within an outer cannula;
- interposing a retracting portion at least partially within an outer cannula;
- coupling a retracting biasing portion to the retracting portion such that a first actuator configured to at least partially release the retracting biasing portion will cause movement of at least a portion of the retracting portion to selectively retract a site marker from outside of the outer cannula to at least partially inside of the outer cannula, such that the marker is retained at least partially within the outer cannula;
- coupling a deployment biasing portion to the outer cannula for moving the outer cannula in a generally axial direction relative to the first member and the site marker;
- and
- sterilizing the deployment device with a site marker not fully interposed within the outer cannula.
A method of deploying a marker, comprising:
- actuating a first actuator to at least partially release a first biasing portion of a site marker deployment device, wherein the first biasing portion is coupled to a retracting portion configured to retract a site marker within an outer cannula, to thereby selectively retract a site marker from outside of the outer cannula to at least partially inside of the outer cannula, such that the marker is retained at least partially within the outer cannula;
- inserting at least a portion of the outer cannula within a desired site marker location;
- and
- actuating a second actuator to at least partially release a second biasing portion of the site marker deployment device to retract the outer cannula such that a distal end of the outer cannula is moved toward a proximal end of the site marker deployment device relative to the site marker.
