Introduction
This document specifies particular requirements for active implantable medical devices intended
to deliver a medicinal substance to site-specific locations within the human body, to provide basic
assurance of safety for both patients and users. It amends and supplements ISO 14708-1:2014. The
requirements of document take priority over those of ISO 14708-1.
An implantable infusion pump system is a device that delivers either a constant flow rate or a variable
flow rate from which a medicinal substance is delivered via an implanted catheter to site-specific
locations within the human body. An external programmer might be used to adjust device parameters.
Requirements for physiologic sensing functions of implantable infusion pump systems are not included in
this edition of this document but might be considered in future editions.
Annex A, Annex B and Annex C are provided for information only.

6 Requirements for particular active implantable medical devices
6.1 Implantable infusion pump system specifications
The specifications (e.g. infusion accuracy and repeatability) stated by the manufacturer in the
accompanying documentation (see 28.8) shall be maintained over the service life and over the range of
environmental conditions and characteristics (e.g. reservoir volume) stated by the manufacturer.
NOTE Minimum environmental conditions for atmospheric pressure are specified in Clause 25.
Infusion accuracy shall be stated for all selectable rates (including bolus rates).
The manufacturer shall provide a plot of infusion accuracy versus environmental conditions and
characteristics (e.g. reservoir volume) that affect infusion accuracy. For variable rate implantable infusion
pump systems, the plot shall contain curves for minimum rate, maximum rate, and at least one rate in
between the minimum rate and maximum rate.
The method of computing and determining the infusion accuracy shall be clearly stated in the
accompanying documentation. Environmental test conditions used to establish infusion accuracy shall
also be stated. Environmental conditions and characteristics that affect infusion accuracy shall be
clearly stated in the accompanying documentation.
For all selectable infusion rates, the repeatability of the actual rate shall also be stated. The method
of computing and determining the stated repeatability shall be clearly described in the accompanying
documentation.
Compliance is checked by inspection of accompanying documentation and test procedures and reports,
supported by the manufacturer’s calculations, as appropriate.
6.2 Septum puncture test
A septum that allows entry to an access port (e.g. refill access port or catheter access port), shall be able
to withstand repeated insertions of a hypodermic needle while maintaining the integrity of the fluid
reservoir throughout the service life.
Test: The DUT shall be conditioned at 37 °C ± 1 °C for not less than 12 h to achieve thermal equilibration.
Each pump septum shall be punctured randomly using the needle specified by the manufacturer for
septum puncture and in accordance with the manufacturer’s instructions. The needle used for septum
puncture shall be replaced if damage to the needle or the needle’s tip is noted by the operator. The
needle shall completely penetrate the septum and care should be taken not to damage the needle’s tip
during the test. Puncturing shall be done using a straight-line motion parallel to the septum's axial
centre-line as shown in Figure 1.
Septum leakage shall be determined by immersing the test unit in a water bath at 37 °C ± 1 °C and
allowing the temperature of the assembly to stabilize for a minimum of 30 min. Leakage shall be
determined by air pressure applied slowly to a pressure of twice the pump’s maximum operating
pressure or a minimum of 276 kPa. The septum’s exposed surfaces shall be examined for air bubble
leakage for 1 min.
The maximum number of punctures for which the septum maintains integrity shall be stated (see 28.8).
Compliance is checked by inspection of accompanying documents and test reports.
