Abstract:
An apparatus comprising: a sheath comprising a plurality of openings at a distal end; an elongate first needle extendible perpendicularly from said sheath through one of said plurality of openings; and an assembly comprising at least two second needles arranged in a predetermined pattern relative to said first needle, and extendible perpendicularly from said sheath, wherein, when extended from said distal end of said sheath: (i) each of said second needles extends a different length from said distal end of said sheath, (ii) at least a distal portion of each of said second needles is resiliently biased to extend laterally outwardly in relation to said first needle, and (iii) a lateral spread region defined by said distal portions of all of said second needles is determined based, at least in part, on a distance of said extending from said distal end of said sheath.
