Product Description
The Bookwalter IMA Retractor System is a table-mounted retractor system designed to provide gentle, controlled elevation of the chest wall during Internal Mammary Artery (IMA) harvesting procedures. The Bookwalter IMA Retractor System is assembled from a 12″ (30 cm) vertical extension bar, a post coupler and a horizontal bar, which together create a stable support framework attached to the operating table.
A 12″ (30 cm) IMA cross bar spans the working area and carries two IMA ratchet mechanisms with micro twist adjustment of less than 1 mm per increment. Because each ratchet is adjusted independently, the two included IMA retractor blades can be raised or lowered separately to achieve the degree of chest-wall elevation required on each side.
All components are manufactured from non-magnetic, surgical-grade stainless steel and are supplied in a dedicated sterilization box for organized storage and processing. The system is reusable and fully autoclavable.
The Bookwalter IMA Retractor System is supplied non-sterile and must be cleaned and sterilized according to the healthcare facility's validated procedures before use. Retractor Maker manufactures the system in Sialkot, Pakistan and supplies it directly to hospitals, surgeons and distributors.

Frequently Asked Questions
What is included in the complete Bookwalter IMA Retractor System?
The complete system includes the sternal frame and table post assembly, the IMA ratchet mechanism and hooks, a comprehensive set of sternal and IMA blade varieties, and a dedicated sterilization container for organized processing.
What is the Bookwalter IMA Retractor System used for?
The Bookwalter IMA Retractor System is a table-mounted, self-retaining surgical retractor engineered to provide steady, hands-free exposure of deep operative fields. By anchoring directly to the operating table rails and locking blades under mechanical counter-traction, it eliminates assistant muscle fatigue and prevents tissue slip during long procedures.
Which surgical procedures is it for?
This system is indicated for cardiac and thoracic procedures, including internal mammary artery harvest, CABG and sternotomy exposure.
What material and finish are used?
Every component is manufactured from non-magnetic, surgical-grade stainless steel. All surfaces are treated with a non-reflective satin finish to suppress glare under intense operating room lighting.
Is it reusable and autoclavable?
Yes. The entire Bookwalter IMA Retractor System is 100% reusable and fully validated for standard steam autoclave sterilization cycles (pre-vacuum steam at 134°C / 273°F). All mechanical clamps, ratchets and joint connections should be loosened or disassembled prior to cleaning and autoclaving.
Can components and blades be ordered separately?
Yes. Hospitals, clinics and distributors can purchase individual replacement parts — including specific blade depths, ratchet mechanisms, frame rings, post couplers and storage cases — as open-stock catalog items without needing to buy a complete system.
Can custom blade dimensions or private-label markings be ordered?
Yes. Because Retractor Maker is a direct manufacturer, we provide custom blade modifications (such as extended depths or specialty curves), bespoke frame sizing, and custom laser etching for hospital asset tracking or OEM branding.
What is the standard lead time and delivery timeframe for orders?
For in-stock instruments, orders take 5 business days to process and inspect, followed by 7 business days for worldwide delivery. For back-order or custom-manufactured systems, production takes 17 to 20 business days, followed by 9 business days for delivery. Full tracking details are supplied upon dispatch.
