1 Description and Intended Purpose
These Instructions for Use are intended for use by the practitioner and user unless otherwise
stated.
The term device is used throughout these instructions for use to refer to TT Pro.
Please read and ensure you understand all instructions for use, in particular all safety information
and maintenance instructions.
Application
This device is for use as a component of a lower limb prosthesis.
Intended for single user.
The device is a shock and torsion device that balances shock absorption and energy
management. Reduced stress at the interface between the body and the prosthesis provides
greater comfort for users.
Activity Level
This device is recommended for users that have the potential to achieve Activity Level 3 or 4. Of
course there are exceptions and in our recommendation we want to allow for unique, individual
circumstances and any such decision should be made with sound and thorough justification.
Note... The maximum user weight for Level 4 users is 100 kg (220 lb).
Activity Level 3
Has the ability or potential for ambulation with variable cadence.
Typical of the community ambulator who has the ability to traverse most environmental barriers and
may have vocational, therapeutic, or exercise activity that demands prosthetic utilization beyond
simple locomotion.
Activity Level 4
Has the ability or potential for prosthetic ambulation that exceeds basic ambulation skills, exhibiting
high impact, stress, or energy levels. Typical of the prosthetic demands of the child, active adult, or
athlete.
Contraindications
This device may not be suitable for Activity Level 1 individuals or for competitive sports events,
as these types of users will be better served by a specially designed prosthesis optimized for their
needs.
Ensure that the user has understood all the instructions for use, drawing particular attention to
the maintenance and safety information.
