AlboGraft® Polyester Vascular Graft
Instructions for Use – English
Description
AlboGraft® Vascular Grafts are made of synthetic material and designed to replace sections of damaged or
malfunctioning arteries. They are made of polyester (polyethylene terephthalate, PET) thread woven into
a seamless tube. In response to a range of surgical indications, AlboGraft Vascular Grafts are off ered in two
designs: double velour knitted fabric and double velour woven fabric. The knitted grafts are designed with a
run-proof structure to reduce the risk of fraying or wearing down at their ends. The velour grafts have low-
profi le loops on their endoluminal surface to avoid any lumen reduction, and high profi le loops on their outer
surface to promote graft anchoring into the surrounding tissues. All AlboGraft grafts are crimped in parallel
rings so that their tubular shape is maintained without kinking.
AlboGraft Vascular Grafts are available with removable external spiral reinforcement (ASC models) made of a
radiopaque biocompatible polypropylene thread, allowing for easy identifi cation of the prosthesis with x-ray.
The external spiral reinforcement is removable, facilitating the creation of anastomoses to the vessel.
Note: AlboGraft Vascular Grafts with Removable External Spiral (ASC Models) are not available for sale in the
United States or Canada.
Guidelines on the outer surface of the graft facilitates orientation during implantation.
The AlboGraft Vascular Grafts impregnated with collagen reduce the permeability to mitigate the problem
of hemorrhaging during implantation so that no preclotting is necessary. The process of impregnation using
bovine collagen maintains both the original structure of the material, and the structural characteristics of the
prosthesis, i.e. fl exibility and softness. The collagen is cross-linked by formaldehyde steaming to ensure a bal-
anced reabsorption rate by the host tissues.

Available Models

AlboGraft Vascular Grafts are available in a wide range of models, types and sizes. The graft can be classifi ed
into models according to fabric characteristics, each model being of one or more types (straight " " or bifur-
cated " " ) and sizes (diameter, length). Each graft is identifi able by a model number and a lot/serial number.
The 3-letter code identifi es the fabric and presence or absence of collagen (see table below); the lot and serial
number serves to retrieve information from the fi les of the LeMaitre Vascular Quality Assurance System on
the graft's manufacturing and quality control data. To facilitate the tracking of the product by the operator all
product identifi cation data is given on self-adhesive labels in each product package, which can be transferred
to the patient's clinical record.

Technical Characteristics of the AlboGraft Prostheses
Diameter
The diameter is defi ned as the value of the nominal internal diameter of the undilated prosthesis. The value is
obtained with a conical gauge (anulometer) having a 10° angle from the apex. The prosthesis is gently slipped
over the instrument without applying any pressure (see diagram).
D120 = Diameter of the prosthesis under pressure
