Abstract
Abstract In order to later identify the location of a biopsy or surgery, various means and methods for permanently and non-surgically marking selected tissue in the human body are used. Later visualization of the markers is readily accomplished using state-of-the-art imaging systems.

Claim 2
Dependent Claim
79 words
A marker instrument comprising: a cube comprising: a lumen; an axial opening at a proximal end of said tube; a closed tip at a distal end of said tube; a side exit port proximal to said closed tip; and a plurality of marker elements disposed in said lumen; wherein said plurality of marker elements includes at least one radiopaque marker element, and wherein at least one marker has a shape different from that of at least one other marker.
Claim 3
Dependent Claim
15 words
A marker instrument, according to claim 1 wherein at least one marker comprises a metal.
Claim 4
Dependent Claim
15 words
A marker instrument according to claim 1 wherein at least one marker comprises non-metallic material.
Claim 5
Dependent Claim
24 words
A marker instrument according to claim 1 wherein at least one marker has a size different from that of at least one other marker.
Claim 6
Independent Claim
99 words
A device for deploying a tissue marker at a biopsy site, the device comprising: a lube comprising: a lumen; and a side exit port communicating with said lumen; a plurality of tissue markers disposed in said lumen proximal of said side exit port; an element slidably disposed in said lumen for pushing said markers distally in said lumen for deployment of said markers through said side exit port; wherein at least one of said markers is visible using an imaging system, and wherein at least one marker has a size different from that of at least one other marker.
Claim 7
Independent Claim
99 words
A device for deploying a tissue marker at a biopsy site, the device comprising: a lube comprising: a lumen; and a side exit port communicating with said lumen; a plurality of tissue markers disposed in said lumen proximal of said side exit port; an element slidably disposed in said lumen for pushing said markers distally in said lumen for deployment of said markers through said side exit port; wherein at least one of said markers is visible using an imaging system, and wherein at least one marker has a size different from that of at least one other marker.

Claim 16
Independent Claim
79 words
A device for deploying a tissue marker at a biopsy site, the device comprising: a tube comprising: a lumen; a side exit port communicating with said lumen; a plurality of discrete tissue markers disposed in said lumen, wherein at least one marker has a size different from that of at least one other marker; and an element disposed in said lumen for pushing said markers distally in said lumen for deployment of said markers through said side exit port.
Claim 17
Independent Claim
79 words
A device for deploying a tissue marker at a biopsy site, the device comprising: a tube comprising: a lumen; a side exit port communicating with said lumen; a plurality of discrete tissue markers disposed in said lumen, wherein at least one marker has a size different from that of at least one other marker; and an element disposed in said lumen for pushing said markers distally in said lumen for deployment of said markers through said side exit port.
Claim 18
Independent Claim
