Indications for Use
The intended use of the Invacare INT /DL40i Controller is to activate and control powered wheelchair motion. Additionally, it provides a method of selecting the type of operational parameters which best suit the particular control needs of the wheelchair user.
Device Story
The INT/DL40i is an electronic microcomputer-based motor controller for power wheelchairs. It integrates a joystick and motor control module into a single unit. The device processes user input from the joystick to activate and control wheelchair motion. It features two drive modes and twelve performance adjustment settings, which are configured via a separate external programming device. The controller is operated by the wheelchair user to navigate and adjust performance characteristics to meet individual control needs. It does not support 'Through the Joystick Programming' (TTJP), Sip N Puff, or seat reclining modules. The device is intended for use on Invacare power wheelchairs, specifically the Pronto M41 model.
Clinical Evidence
Bench testing only. Performance was verified against ANSI/RESNA WC/Vols. 1&2 (1998) standards, including static/dynamic stability, braking effectiveness, energy consumption, dimensions, speed/acceleration, fatigue strength, climatic testing, obstacle climbing, power/control systems, and electromagnetic compatibility (CISPR 11).
Technological Characteristics
Microcomputer-based digital controller; microprocessor drive control; surface and through-hole mounted PC boards. Enclosure: pressure die-cast aluminum bottom and injection-molded polymer top. Connectivity: supports external remote programmer. Standards: ANSI/RESNA WC/Vols. 1&2 (1998) and CISPR 11 for electromagnetic compatibility.
Indications for Use
Indicated for power wheelchair users requiring control of wheelchair motion and adjustment of operational performance parameters.
Regulatory Classification
Identification
A powered wheelchair is a battery-operated device with wheels that is intended for medical purposes to provide mobility to persons restricted to a sitting position.

Legally Marketed Predicate Device(s): INT/DL40i Micro Computer Control for Power Wheelchairs; K950724, August 7, 1995
Device Description: The INT /DL40i controller is an electronic microcomputer based motor control device for power wheelchairs intended to activate and control the wheelchair motion. It also provides the means for selecting, adjusting and programming the type of wheelchair operation parameters and performance characteristics to meet the particular control needs of the wheelchair user.
The INT/DL40i controller consists of a single module that includes both the joystick and the motor controller. It has two drive modes and twelve performance adjustment settings in its program menu. Programming the controller requires the use of a separate programming device since it does not have "Through the Joystick Programming" (TTJP) capability. Also, the INT/DL40i controller does not include any additional motion control activation devices such as "Sip N Puff" or seat reclining.
Intended Use: The intended use of the Invacare INT /DL40i Controller is to activate and control powered wheelchair motion. Additionally, it provides a method of selecting the type of operational parameters which best suit the particular control needs of the wheelchair
