Document Type and Number:
Japanese Patent JP5461660
Kind Code:
B2
Abstract:
An optical obturator for penetrating tissue includes an outer member defining a longitudinal axis and having proximal and distal ends, a leading member disposed adjacent the distal end of the outer member and having an optical window adapted to permit passage of light therethrough for detection by a clinician, and a penetrating member mounted adjacent the leading member and having a penetrating surface adapted to facilitate penetrating of tissue. The leading member is adapted for longitudinal movement between a first longitudinal position and a second longitudinal position. The penetrating surface of the penetrating member is at least partially exposed upon movement of the leading member from the first longitudinal position to the second longitudinal position.
