Method and apparatus for inserting biopsy site marker in marker body
First Claim
1. An apparatus for inserting a marking element into a marker body, the apparatus comprising:
- (a) a marker body having a first length, wherein the marker body comprises a bioresorbable portion;
(b) a marking element wherein the marking element is insertable into the marker body, wherein the marking element has a second length, wherein the second length is less than the first length of the marker body;
(c) a body portion having a compartment, wherein the marker body is disposed in the compartment;
(d) an insertion member, wherein part of the insertion member is inserted in the marker body within the compartment; and
(e) a pushing member, wherein the pushing member is configured to engage with the insertion member, wherein the pushing member is operable to force the marking element along the insertion member into the marker body;
wherein the marker body containing the marking element is insertable into a body cavity wherein the insertion member comprises a hollow needle;
wherein the pushing member comprises a pin configured to pass through at least a portion of the hollow needle;
wherein the pushing member further comprises a pushing body portion, wherein the pin extends from the pushing body portion;
wherein the position of the pin relative to the pushing body portion is adjustable;
wherein the pushing member further comprises a fixation member, wherein the fixation member is operable to selectively secure the position of the pin relative to the pushing body portion.

Abstract
An apparatus for inserting a marking element into a marker body includes a body portion, an insertion member, and a pushing member. The body portion has a compartment configured to receive a marker body. The insertion member is configured to engage the marker body within the compartment. The pushing member is configured to engage with the insertion member. The pushing member is operable to force a marking element along the insertion member into the marker body. The insertion member may include a hollow needle configured to penetrate the marker body. The pushing member may include a pin configured to fit within the hollow needle. The marker body may include an opening such as a slit, a slot, or a passage that is configured to receive a marking element. The marker body may include a collagen dowel, and the marking element may be formed of titanium.
