Abstract: A guiding apparatus comprises a plurality of collapsible support members and a plurality of retraction assemblies. Each of the plurality of retraction assemblies is coupled to a respective one of the plurality of collapsible support members. The plurality of collapsible support members have an extended configuration in which the plurality of support members are arranged to form a channel extending along a longitudinal axis. The channel is sized to receive an elongated instrument. The plurality of support members have a collapsed configuration in which each of the plurality of support members is retracted within the respective coupled retraction assembly as the elongated instrument is advanced along the longitudinal axis.
