Device verification testing. (a) Example setup for testing insertion using the Instron. (b) Force required for insertion of PeriPath into an incision. This passes the clinically relevant acceptance criteria of <1 N stated in Table 1. (c) Forces required for flange deployment of the device. This passes the clinically relevant acceptance criteria of <10 N stated in Table 1. (d) Force required to dislodge the device axially. This passes the clinically relevant acceptance criteria of >10 N stated in Table 1. (e) Torque produced during cyclic rotations. This passes the clinically relevant torque acceptance criteria of <0.01 N·m stated in Table 1. (f) Drag forces required to insert tools within the larger visualization channel. This passes the clinically relevant acceptance criteria of <10 N and >2 N stated in Table 1. Each line represents a different specimen for each test. Dotted lines represent force or torque threshold rounded to the nearest Newton that would result in fracture.
