Brachytherapy device

A device for depositing objects into tissue of an animal, comprising:

• a cannula having a sidewall defining a passageway for the objects, a proximal end and an opposite distal end insertable into tissue, said distal end defining an exit aperture in communication with said passageway, said sidewall having a distal portion adjacent said distal end and a proximal proximate said proximal end, said distal portion defining a flexible tab positionable across at least a portion of said passageway.

An assembly for depositing objects into tissue of an animal, comprising:

• a cannula having a sidewall defining a passageway for the objects, a proximal end and an opposite distal end insertable into tissue, said distal end defining an exit aperture in communication with said passageway, said sidewall having a distal portion proximate said distal end and a proximal portion adjacent said proximal end, said distal portion defining a distal retaining tab positionable to block at least a portion of said passageway;
• and
• a stylet slidable within said passageway to urge the objects out through said if exit aperture.
