Abstract
A method of securing a biopsy marker within a biopsy site includes depositing a marker element within a biopsy site and fixing the marker element within the biopsy site by injecting a securing agent within the biopsy site. Delivery devices for delivering the securing agent to the biopsy site are also disclosed.
Claims23
A delivery device, comprising:
- a cannula defining an inner lumen therein, the cannula having a proximal end and a distal end;
- a valve member secured to the cannula, wherein the valve member is secured generally toward the distal end of the cannula;
- an actuation portion connected to the proximal end of the cannula;
- a semi-permeable filter element positioned within the cannula between the valve member and the actuation portion, the filter element cooperating to form a cavity between the valve member and the filter element;
- wherein the cavity is configured to hold a securing agent and wherein the actuation portion may be selectively depressed to cause a fluid to flow through filter element and force the securing agent through the valve member.
2 more elements
The device of claim , further comprising a seal member disposed around a portion of the plunger.
A device comprising:
- an outer cannula having an open distal end;
- an inner cannula disposable within the outer cannula and having a selectively openable distal end;
- and
- an actuation member disposed in the inner cannula;
- wherein the outer cannula is configured to house a marker element distally of the inner cannula and the inner cannula is configured to house a securing agent;
- and
- wherein the actuation member is configured to extend through the inner cannula and the outer cannula such that the actuation member contacts the securing agent and the marker element thereby forcing the securing agent and the marker element out of the open distal end of the cannula.
4 more elements
A device, comprising:
- a cannula defining an inner lumen therein;
- a cap member attached to a distal end of the cannula and generally closing off the inner lumen;
- and
- an actuation member slidably disposed within the inner lumen;
- wherein the cap member and the actuation member cooperate with the inner lumen to define a cavity configured to receive a securing agent;
- and
- wherein the actuation member is selectively movable distally toward the cap member to rupture the cap member from the distal end of the cannula to expel the securing agent from the cannula.
