ABSTRACT:
A device suitable for insertion into a mammalian body comprises an elongated tube or cannula, an elastic member for bending the cannula, and a straightener preventing the elastic member from bending the cannula. The straightener and elastic member are capable of relative axial movement, so that the elastic straightener can be positioned to prevent or allow the elastic from bending the cannula. Preferably the elastic member is formed from a superelastic shape-memory alloy. Other versions of the device without a straightener are described.
