Abstract:
1. An apparatus for treating tissue of a mammalian body comprising a housing having an internal chamber, a first tubular member, and a second tubular member slidably disposed in the first tubular member, the housing, the first tubular member and the second tubular members having respective proximal and distal portions, the proximal portions of the first and second tubular members being coupled to the housing, the distal portion of the second tubular member being provided with a needle, an actuatable spring mechanism for moving the second tubular member relative to the first tubular member such that the needle moves from a first position disposed within the distal portion of the first tubular member to a second position extending distally of the first tubular member, wherein when the needle is at the first position the proximal portion of the second tubular member is bowed to accommodate the movement of the second tubular member relative to the first tubular member.
