Medtronic EEA31 Circular Stapler with DST Series Technology

The Medtronic EEA31 Circular Stapler with DST Series Technology is designed to deliver secure, consistent anastomoses in colorectal, gastric, and esophageal surgical procedures. Featuring 4.8mm staples, the EEA31 offers enhanced compression and tissue capture with a 31mm diameter, optimizing performance across a wide range of tissue thicknesses. The DST Series Technology incorporates directional staple formation and graduated staple heights to promote uniform tissue compression and reliable healing. A tilting anvil head and shaft articulation provide superior access and maneuverability in challenging anatomical spaces. Engineered for ease of use and procedural efficiency, the EEA31 stapler supports reduced anastomotic leak rates and improved patient outcomes in gastrointestinal surgery.

Additional Details

• Brand: Medtronic
• Category: Surgical Stapling
• Type: Circular Stapler, Disposable
• FDA Product Code: GAG, GDW
• FDA Product Code Name: Stapler, Surgical Stapler, Implantable
• GMDN Term Code: 59875
• GMDN Term Name: Intraluminal circular stapler, single-use
• GMDN Term Definition: A sterile, hand-held, manual surgical instrument intended to be used during open or laparoscopic surgical procedures of the alimentary tract, to create anastomoses (e.g., end-to-end, end-to-side, or side-to-side) via intraluminal (within the lumen) resection. It is designed to connect two portions of lumen (e.g., colon) with a single or multiple circular rows of staples, and then cut out the tissue within the staple line to create a new channel. This device operates via a manual lever mechanism and may be available in a variety of sizes appropriate to a specific luminal diameter. This is a single-use device.

Covidien’s AutoSuture business now resides within Medtronic’s Surgical Operating Unit, under the Medical Surgical Portfolio. This group is focused on delivering advanced technologies for minimally invasive surgery, with a deep legacy in surgical stapling, energy devices, and laparoscopic instrumentation.

Key products from the former AutoSuture line include:

• Endo GIA™ staplers and reloads – a flagship line of linear cutting staplers used in a variety of laparoscopic and open procedures.
• Signia™ – a powered stapling platform offering real-time feedback and adaptive firing technology.
• LigaSure™ – a trusted vessel sealing system for tissue fusion and hemostasis.
• VersaOne™ trocars – for secure and versatile access during minimally invasive surgery.
• Sonicision™ – cordless ultrasonic dissection tools that combine energy and precision.

These technologies form the backbone of Medtronic’s minimally invasive surgical portfolio, originally developed under the AutoSuture brand by U.S. Surgical Corporation, then acquired by Tyco Healthcare, which later became Covidienbefore merging with Medtronic in 2015. Today, Medtronic continues to build on this heritage, delivering solutions that enhance efficiency, precision, and outcomes in the operating room.
