2. Indications
The HAART 301 Instrument Set is intended to be used
as an aid in the implantation of the HAART 300 Aortic
Annuloplasty Device.
3. Description
The HAART 301 Instrument Set consists of four (4) Sizers,
one (1) Gage Sphere, and two (2) Handles provided in a
stainless steel tray (Figure 1 on page 116). The Instrument
Set is used to select the proper HAART 300 Aortic
Annuloplasty Device size for a given patient and to assist
in the assessment of leaflet coaptation after completion
of the overall repair of the aortic valve. The HAART 301
Instrument Set is reusable; however, it must be cleaned
and sterilized by autoclave (steam) prior to each use.
Refer to the sections below for detailed information on
accessory use and sterilization.
3.1 Handle
The Handle is machined from ASTM A276 stainless steel,
and cleaned and passivated per ASTM specification
F86. The Handle may be threaded into the Sizers, Gage
Sphere, and Holder to facilitate positioning during the
procedure (Figure 2 on page 116). The stainless steel
Handle may be bent in the narrowed section to present
the Sizers, Gage Sphere, and Device to the surgical site
in the desired manner. The Handle is very similar in design
and manufacture to handles supplied with replacement
heart valve prostheses and is intended to be used in a
similar manner.
3.2 Sizers
The Sizers are machined from polyphenylsulfone. Each
Sphere has a through hole along its axis (Figure 3 on
page 117). The top of the through hole is threaded to
receive the instrument Handle.
The Sizers are laser marked with a line at the equator
and 15° wide stippled regions, oriented 180° apart, to
assist the user with assessment of leaflet free-edge
length. The size of the corresponding HAART 300
device is prominently marked on its upper surface of
each Sizer. Reference lines dividing the Sphere into 120°
sections are provided for assessing symmetry of the valve
commissures and leaflets.
3.3 Gage Sphere
The Gage Sphere is machined from polyphenylsulfone
and has a through hole along its axis. The top of the
through hole is threaded to receive the instrument Handle.
After completion of leaflet repair, effective height and
leaflet geometric height may be assessed using the
Gage Sphere provided in the HAART 301 Instrument
Set. The Gage Sphere has two different vertical scales
laser marked on the surface (Figure 4 on page 118). One
scale originates at the apex of the Sphere and is intended
for estimating the effective height of the valve leaflet.
For a successful repair, leaflet effective height should
be approximately 8 to 10 mm. The second scale may be
used to assess leaflet geometric heights, when desired,
for further evaluation of leaflet size and symmetry after
the overall valve repair.
