Abstract
An apparatus for delivery of a biopsy marker to a biopsy site includes a grip, a cannula, at least one biopsy marker, and a sterile guide. The cannula extends distally from the grip and includes a lumen extending at least partially therethrough. A maker exit opening is defined by the cannula and is in communication with the lumen. The at least one biopsy marker is disposed in the lumen for deployment through the marker exit opening. The sterile guide is slidable along the cannula and is configured to selectively fasten to the grip.
Claims20
An apparatus for delivery of a biopsy marker to a biopsy site, the apparatus comprising:
- (a) a grip and a cannula extending distally from the grip, the cannula having a lumen extending at least partially therethrough and a marker exit opening in the cannula communicating with the lumen;
- (b) at least one biopsy marker disposed in the lumen for deployment through the marker exit opening;
- and
- (c) a sterile guide including a body configured to slide along the cannula, wherein the sterile guide further includes a radially extending grasping feature of unitary construction with the body.
A biopsy system comprising:
- (a) a biopsy device operable for taking one or more biopsy samples from a patient, the biopsy device comprising a needle and a cutter for severing tissue received within the needle;
- (b) a marker delivery device, the marker delivery device including a handle and a cannula extending distally from the handle having a marker lumen and at least one marker disposed in the marker lumen;
- and
- (c) a sterile guide positionable on the cannula, wherein the sterile guide is removably coupled to the handle and the cannula, simultaneously, and is configured to selectively slide along the length of the cannula when de-coupled from the handle to direct the cannula into the needle of the biopsy device.
A method for guiding a marker delivery device relative to a biopsy instrument, the method comprising:
- (a) preparing the marker delivery device for removal from a package by detaching a sterile guide from a handle of the marker delivery device and sliding the sterile guide along a cannula of the marker delivery device to a deployment position proximate a distal tip of the cannula;
- (b) removing the marker delivery device from the package by grasping the sterile guide and the handle of the marker delivery device;
- and
- (c) guiding the distal tip of the cannula into a portion of the biopsy instrument by aligning the sterile guide with the biopsy instrument.
