Patent Images
1. A tissue caliper comprising:
- a housing assembly including a tubular body, the tubular body having proximal and distal ends;
an activation assembly operably disposed within the tubular body, the activation assembly including a magnetic spring and an end cap disposed on a proximal end of the magnetic spring for activating the magnetic spring; and
a caliper assembly disposed on the distal end of the tubular body, the caliper assembly being operably connected to the activation assembly, wherein activation of the magnetic spring effects opening and closing of the caliper assembly.

18. A tissue caliper comprising:
-
a housing assembly; an activation assembly operably received within the housing assembly; a caliper assembly operably connected to the activation assembly, wherein the activation assembly includes a magnetic spring for effecting the opening and closing of the caliper assembly; a display assembly for displaying a measurement of thickness of a material operably engaged by the caliper assembly; and a switch assembly for locking the measurement displayed by the display assembly, the switch assembly including a switch and an RC control circuit, wherein the RC control circuit is configured to lock the displayed measurement between two (2) seconds and five (5) seconds after the release of the switch.
