Minimal Invasive Lumbar Atavi® Atraumatic Spine Surgery System

Features and Benefits

The Atavi Atraumatic Spine Surgery System is a single, integrated minimally invasive system that enables surgeons to perform a full range of lumbar spine fusion procedures - through one access portal - without changing the traditional open surgical technique. Atavi, which combines unique access technology, and sophisticated visualization and instrumentation capabilities, requires one small incision on each side of the spine during the entire procedure.

Atavi Access

The cornerstone of Atavi is the Atavi FlexPosure® Retractor, a patented access portal that is inserted through a small incision and expanded at the spine to establish and maintain substantial surgical exposure to the affected areas of the spine. The FlexPosure functions as a single access portal that enables surgeons to:

  • Perform a full range of lumbar spine fusions minimally invasively, including single and two-level fusion, fixation and decompression, as well as lumbar interbody fusion, without changing the traditional surgical technique.
  • Gain access to the surgical site, prepare the fusion bed, deliver bone graft, and place fixation devices without having to readjust the access.
  • Preserve healthy muscle and soft-tissue by using a gentle, step dilation process to insert the FlexPosure through one small posterior incision on each side of the spine.

Atavi Visualization

Atavi Visualization provides superb illumination to the surgical site via many visualization means including Direct View, Surgical Loupes, and Microscope. Atavi visualization enables easy identification of the anatomy, effective site preparation, and delivery of implants and graft. With this MIS system, surgeons can:

  • View the surgical field and achieve better visual acuity than is possible with an open fusion.
  • Accurately navigate the surgical site with circumferential, real-time visualization throughout the procedure.

Atavi Instrumentation

  • Atavi's MDS™ MicroDebrider System (MDS) with the BiPolar Sheath enables surgeons to efficiently clear soft-tissue from the surgical site while dramatically decreasing blood loss. The MDS is a unique, multitask device that enables surgeons to debride and coagulate muscle and soft-tissue, and evacuate the debris simultaneously - increasing procedure efficiency significantly.
  • Atavi's manual surgical instruments are based on those used in the open surgical technique - yet are ergonomically enhanced for the minimally invasive approach.

Expanded Atavi Capabilities

Atavi-trained surgeons are able to treat nearly 80 percent of all patients who require lumbar spine fusion - using one system, one access portal, and two small incisions on each side of the spine, all without changing the traditional open surgical technique.

TiTLE 2:

  • Atavi TiTLE® 2 is the first top-loading rod fixation system that enables surgeons to perform single and multi level spine fusion and fixation minimally invasively.
  • TiTLE 2 is an ideal top-loading pedicle screw system optimized for open fusion procedures.  

Atavi Decompression:

  • Atavi enables single and two-level decompression, which for the first time can be completed through the same access portal as single and two-level fusion and fixation, without changing the traditional surgical technique.

MiLIF:

  • Minimally invasive lumbar disc preparation instrumentation is specifically designed for use with the Atavi System

Atavi Versus Open Spine Fusion:

  • Traditional open spine fusion is highly traumatic, requiring a 5-7 inch midline incision, wide stripping, and cutting and prolonged muscle retraction.
  • Patient trauma during the procedure often results in muscle damage, scarring and blood loss. Patients can suffer from chronic post-operative pain and endure lengthy recovery times.
  • Atavi enables a complete posterior lumbar spine fusion through one access portal and one small incision on each side of the spine - without changing the traditional surgical technique.
  • Atavi dramatically decreases the morbidity associated with the open fusion procedure by preserving healthy muscle and soft-tissue, and decreasing blood loss, post-operative pain and recovery times.
  • Patients are able to leave the hospital quicker, decrease their reliance on narcotic pain medication, and return to their normal daily routines within weeks.
  • Hospital and insurance costs associated with lengthy hospital stays, pain management, physical therapy and loss of productivity can potentially be reduced by hundreds of millions of dollars annually with Atavi.

Atavi Minimally Invasive Versus Other Minimal Access Systems:

  • Most other minimal access retractors systems provide a mini-open approach requiring rigid bladed retractors. These retractors increase the incisions length required for procedures, do not offer the flexibility that the Atavi system offers, and limit the capabilities of fluoroscopy through the dense retractor systems.
  • Other less invasive spine surgery systems force surgeons to operate 'blind' - requiring them to rely on fluoroscopy alone, or use a straight access portal, which limits the surgeon's field of vision and access to the spine.
  • Manipulation of surgical instrumentation is often limited with straight access portal systems, due to an inability to create and maintain a substantial working space at the spine.
  • Multiple incisions and operations are often required to complete other minimally invasive spine fusion procedures.
  • Atavi is a single, integrated minimally invasive surgical system and does not alter the traditional surgical technique, resulting in shorter learning curves.
  • Atavi access, visualization and instrumentation capabilities provide advantages over percutaneous approaches that don't allow surgeons to visualize the anatomy, control bleeding, prepare the fusion bed, deliver fusion graft, or perform decompression.
  • Atavi instrumentation includes the state-of-the art multitask Atavi MDS and BiPolar Sheath for simultaneous debridement and coagulation, irrigation and evacuation, along with a set of manual instruments that are based on familiar tools used in the open procedure.
