A cartridge for dispensing at least one material comprising: a body portion and a tube portion, the body portion having a hollow tubular portion, said hollow tubular portion having a radial direction and an axial direction, said hollow tubular portion having at least two locking members extending from said hollow tubular portion along said axial direction away from the remainder of said body portion, said at least two locking members comprising a distal end which is distal from the hollow tubular portion for forming a temporary locking engagement with at least a portion of an external force applying member,; and the tube portion extending away from the body portion at a point which is opposite to the at least two locking members of the body portion, said tube portion including, in an increasingly distal from the body portion successive arrangement; an accessible compartment, a neck portion and a finger portion; a force translating means, at least a portion of the force translating means slidably housed within the finger portion, the force translating means configured for contacting a portion of an external force applying member; and a tip portion configured to accept a quantity of a dispensable material, wherein, the material can optionally be dispensed to a location within the mammalian body; characterized in that said distal ends of the at least two locking members are further connected by means of connectors to a circular ring located more distally from the hollow tubular portion than said at least two locking members' most distal portions are from said hollow tubular portion, wherein said circular ring is attached to the body portion by means of vertical rods; and said finger portion comprises a corrugated portion. a body portion and a tube portion, the body portion having a hollow tubular portion, said hollow tubular portion having a radial direction and an axial direction, said hollow tubular portion having at least two locking members extending from said hollow tubular portion along said axial direction away from the remainder of said body portion, said at least two locking members comprising a distal end which is distal from the hollow tubular portion for forming a temporary locking engagement with at least a portion of an external force applying member,; and the tube portion extending away from the body portion at a point which is opposite to the at least two locking members of the body portion, said tube portion including, in an increasingly distal from the body portion successive arrangement; an accessible compartment, a neck portion and a finger portion; a force translating means, at least a portion of the force translating means slidably housed within the finger portion, the force translating means configured for contacting a portion of an external force applying member; and a tip portion configured to accept a quantity of a dispensable material, wherein, the material can optionally be dispensed to a location within the mammalian body; characterized in that said distal ends of the at least two locking members are further connected by means of connectors to a circular ring located more distally from the hollow tubular portion than said at least two locking members' most distal portions are from said hollow tubular portion, wherein said circular ring is attached to the body portion by means of vertical rods; and said finger portion comprises a corrugated portion.
