Systems, apparatus, components and methods are disclosed that allow the
clinician to circumvent the pubic arch in instances where it interferes
with insertion of instrumentation into the prostate or periprostatic
tissue. The systems, apparatus and components disclosed herein employ
structures, such as needles and trocars, of shape memory alloys, such as
nickel-titanium (Ni--Ti) for the purpose of avoiding the pubic arch when
accessing the prostate from the perineum.
