Needle-Tract Assistant Including Components and Methods Thereof

Abstract:

A needle-tract assistants (100, 200) for establishing a needle tract of a predetermined length, including a needle thruster (110, 210) and a needle-in-catheter assembly (130, 230) removably loaded in the needle thruster (110, 210). The needle thruster (110, 210) can include a cradle (112, 212), a carriage(114, 214) within the cradle (112, 212), and a plunger (116, 216) coupled to the carriages (114, 214). The carriages (114, 214) can be configured to move between a proximal-end portion and a distal-end portion of the cradle(112, 212). The plungers (116, 216) can be configured to move the carriages (114, 214) within the cradle(112, 212). The plungers (116, 216) can also be configured to allow a user to set the predetermined length of the needle tract before establishing the needle tract. The needle-in-catheter assembly (130, 230) can include a hub (132, 232), a catheter tube (134, 234) extending from a distal-end portion of the hub (132, 232), and a needle (137, 237) disposed within the catheter tube (134, 234). Also described are components of the needle-tract assistants (100, 200) and methods of the needle-tract assistants (100, 200) or the components thereof.
