Progress so far… Finalized our design Ordered parts this past Monday Still need to decide on some things yet. . Begun discussing rough ideas on attachment devices Hinges, ball and socket

Future Work Go to Home Depot/Menards to look for attachment mechanisms Locking swivel mechanism

Future Work Go to Home Depot/Menards to look for attachment mechanisms Locking swivel mechanism Construct prototype based on already ordered materials Test completed prototype on simulated catheter procedure
