Instructions for use/Technical description
Federal law restricts this device to sale by or on order of a physician!
Aesculap is not responsible for any complications arising from incorrect diagnosis, choice of incorrect implant,
incorrectly combined implant components and/or operating techniques, the limitations of treatment methods,
or lack of asepsis.
■ The instructions for use for individual Aesculap implant components must be followed.
■ The implant components were tested and approved in combination with Aesculap components. If other combinations are used, the responsibility for such action lies with the operating surgeon.
■ Do not, under any circumstances, combine implant components from different manufacturers.
■ Do not, under any circumstances, use damaged or surgically removed components.
■ Implants that have been used before must not be reused.
■ The implant components applied, along with their article numbers, the name of the implant, as well as the batch
number and serial number (if available) must be documented in all patient records.
■ Postoperatively, individual patient information, as well as mobility and muscle training, is of particular importance.
Each AVM microclip is supplied with additional labels indicating the article number and order number (BATCH) of
the AVM microclip. These labels can be attached to the patient records.
The implants used, along with their article numbers, the name of the implant and the order number (BATCH) must
be documented in all patient records.

Important information about the implanted AVM microclip and the surgical procedure can be noted on the patient
ID. To facilitate the postoperative radiological examination, each patient should receive a patient ID.
■ Contents of the patient ID
– Patient data
– Hospital data
– Date of operation
– Name of surgeon and hospital
– Article number and order number (LOT) of the implanted AVM microclip
The patient ID can be ordered separately from Aesculap.
Caution, general warning symbol
Caution, see documentation supplied with the product
Date of manufacture
The implant components come individually packed in protective packaging that is labeled according to its contents.
■ The implant components are provided sterile by gamma irradiation.
► Store implant components in their original packaging. Remove them from their original protective packaging
only just prior to application.
► Prior to use, check the product expiry date and verify the integrity of the sterile packaging.
► Do not use implant components that are past their expiration date or whose packaging is damaged.
Damage to implants caused by processing and resterilization!
Do not use if the packaging is damaged
►Do not reprocess or resterilize the implants.
►If the packageing is open during surgery and the clip is not used, the
clip must be discarded.
Phynox® Cobalt-based alloy according to ISO 5832-7
The AVM microclips are available in various lengths and in straight and curved designs. Information on the geometry
and dimensions can be found in the AVM microclip brochure. AVM microclips are supplied in sterile packaging.
The closing force range indicated on the label is measured at 1 mm from the distal clip end of the contact surfaces
of the jaw parts, see Fig. 1.
The implant is used for the temporary or permanent occlusion of small vessels in cases of intracranial
arteriovenous malformations (AVM).
Indications for Use
The Aesculap AVM Microclips are intended for intracranial vascular occlusion (permanent or
temporary) of small vessels.
The operating surgeon shall devise an operation plan that specifies and accurately documents the following:
■ Selection of the implant components and their dimensions
■ Location of intraoperative landmarks
The following conditions must be fulfilled prior to application:
■ All components are available.
■ Operating conditions are highly aseptic.
■ Aesculap-AVM applying forceps must be in good working order
■ The surgeon and operating room team are thoroughly familiar with the operating technique and with
the available range of implants and instruments; information materials on these subjects must be available.
The operating surgeon is fully conversant with the rules governing medical practice, the current state of scientific
knowledge, and the contents of relevant scientific articles by medical authors.
The manufacturer has been consulted if the preoperative situation was unclear and if implants were found in the
area operated on.
The patient must have been informed about the procedure and the characteristics of the AVM microclip.
Risk for the patient due to accelerated galvanic activity in connection with other implanted clips!
AVM microclip must only be implanted if it has been ruled out that this will come into contact with implants (e.g. clips)
made from other metals.
Side effects and interactions
Damage to the AVM microclip due to incorrect handling, restriction of the functionality and changing of the closing force!
► AVM microclip must only be taken out of the sterile packaging for its application.
► AVM microclip must only be removed and applied with the Aesculap-AVM
► AVM microclip must never be manipulated with the fingers.
► Avoid repeated opening and closing of the AVM microclip.
Side effects, risks and complications include infections, sensitivity to the implant materials, nerve damage, vascular
damage possibly resulting in hematomas or bleeding, organ and other tissue damage, wound healing disturbances,
and other types of surgical complications.
The following risks may occur in connection with the use of AVM microclips:
■ The AVM microclip may slip out of place or migrate
■ Crossing over of the jaw parts
Damage to the AVM microclip from it slipping out of place, breaking or snapping
► Use only the Aesculap-AVM applying forceps, under no circumstances use
products from other manufacturers.
► Ensure that the AVM microclip is positioned correctly in the applying forceps.
MRI Safety Information
The clips are non-ferromagnetic, which makes them MRI safe.
This means that the clips do not interact with magnetic fields up to 1.5
tesla of magnetic resonance imaging, although larger artifacts can be
AVM microclip is taken out of the double sterile packaging.
Check to make certain that the surfaces of AVM microclips are not bent or damaged.
AVM microclip must be carefully grasped with the Aesculap-AVM applying forceps and removed, see Fig. 2.
AVM microclip is then to be applied. When doing so, ensure that the occlusion of the blood vessel is achieved.
Check the position of the AVM microclip and if necessary correct it or use further AVM microclips.
Further information on Aesculap implant systems is always available from B. Braun/Aesculap or the appropriate
B. Braun/Aesculap office.
The surgeon decides, based on the size of the vessel, whether the AVM microclips are to be used, or whether
larger clips such as Aesculap-Yasargil aneurysm clips need to be used.
The surgeon decides whether the AVM microclips are to be used only for the duration of the operation and
removed before closing up the patient (temporary use), or whether the AVM microclips will remain in the patient
after the operation (permanent use). Both uses are possible with the AVM microclips.
It is the operating surgeon's responsibility to ensure that the surgical procedure is performed properly.
General risk factors associated with surgical procedures are not described in the present instructions for use.
The operating surgeon must have a thorough command of both the hands-on and conceptual aspects of the
established operating techniques.
The operating surgeon must be fully conversant with bone anatomy, including the pathways of nerves, blood vessels, muscles, and tendons.
It is the operating surgeon's responsibility to ensure the correct combination of implant components and their
