An intracorporeal site marker for implantation in a biopsy cavity, comprising:
- a plurality of particles;
- wherein said particles are sintered together to form a unitary body.
An intracorporeal site marker for implantation in a biopsy cavity, comprising:
- at least one strand of wire that is formed into a predetermined shape so as to form a mass of compressed wire, wherein said strand of wire is not visibly identifiable by an imaging modality as a strand of wire in an uncompressed state.
An intracorporeal site marker implanted into a biopsy cavity, comprising:
- a rod having at least one hole therein.
An intracorporeal site marker for implantation into a biopsy cavity, comprising:
- a thin wall hollow capsule having an elongated body;
- said capsule having a closed first end and an open second end;
- a cap welded to close said second open end;
- and
- wherein said capsule is adapted to resonate at a preselected ultrasound frequency.
An intracorporeal site marker for implantation into a biopsy cavity, comprising:
- a plurality of particles that are suspended in a second material that is different than the material of said particles to form a unitary body.
An intracorporeal site marker for implantation into a biopsy cavity, comprising:
- a unitary body that is construction of a biocompatible material that is visible under one or more imaging modalities when said unitary body is positioned within the body;
- wherein said unitary body further includes a plurality of depressions formed on an outside surface of said unitary body.
