No
The device description details a purely mechanical system for creating surgical access ports. There is no mention of any computational or data-driven components that would suggest the use of AI or ML.
No
The device is described as providing "dilation access" and a "port of entry" for other procedures, including diagnostic, therapeutic, and operative ones, but it does not perform a direct therapeutic function itself.
No
This device is designed to create a port of entry for diagnostic, therapeutic, and operative procedures by creating access to various body cavities and organs; it does not perform diagnostic functions itself.
No
The device description clearly details physical components such as an expandable dilator sheath assembly, access needle, blunt obturator, dilation cannula, and pneumo valve. It also mentions assembly from medical grade materials, molding, machining, adhesives, welds, and mechanical interlocks, indicating a hardware-based device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening. This testing is performed outside of the body (in vitro).
- Device Function: The InnerDyne, Inc., Step® device is a surgical access device. Its purpose is to create a port of entry into the body (abdominal cavity, thoracic cavity, hollow organs) to allow for the insertion of other instruments for diagnostic, therapeutic, or operative procedures. It does not analyze or test any biological specimens.
- Intended Use: The intended use clearly describes providing access for procedures, not performing diagnostic tests on samples.
- Device Description: The description details the mechanical components and how the device is used to create an opening in tissue. There is no mention of analyzing biological samples.
Therefore, the InnerDyne, Inc., Step® device is a surgical instrument, not an In Vitro Diagnostic device.

Device Description
The Step Trocar Expandable Port Step® device consists of an expandable dilator sheath assembly with an access (Veress-type) needle mounted within its lumen. The tubular member of the dilator sheath is configured so as to be axially compressed to reduce the outside diameter of the device prior to insertion. Upon use, the expanding dilator sheath/needle assembly is inserted through the abdominal/thoracic tissue into the target cavity or hollow organ.
For laparoscopic access to the abdominal/thoracic cavities, the following instructions should be utilized. After insufflation of the cavity, (if deemed necessary), the access needle is removed. The dilator cannula assembly, which consists of a blunt obturator, dilation cannula, and a pneumo valve, is inserted through the lumen of the dilator sheath which expands radially to accommodate it. This process in turn, radially expands the walls of the surrounding tissue. Following dilation the obturator is removed, leaving the expanding dilation sheath and dilator cannula in place to provide a sealed port for passage of diagnostic, therapeutic, and/or surgical instruments.
For access to hollow body organs (e.g., intragastric placement viewed as typical), the following instructions should be utilized. If endoscopic technique is utilized, an endoscope is advanced into the stomach using standard techniques, followed by stomach insufflation. An abdominal incision is made and the access needle/sheath assembly is inserted directly through the abdominal and stomach walls into the stomach. The access needle is removed and the cannula/dilator is advanced through the radially expanding sleeve. If laparoscopic technique is utilized, under laparoscopic vision the abdominal cavity is entered and the stomach site is selected for insertion of the access device. The sheath/needle assembly, is advanced into the stomach. The access needle is removed, leaving the expandable sheath in place. The dilator cannula assembly is inserted through the lumen of the dilator sheath which expands radially to accommodate it. Following dilation the dilator is removed, leaving the expandable sheath and dilator cannula in place to provide a sealed port for passage of the selected instruments. Once the desired instruments are placed, the access device cannula and expanding sheath are removed, allowing the stomach and abdominal wall to contract/relax. (Access to hollow organs other than the stomach, can be achieved following general laparoscopic technique and the access methodology described above.)
This system configuration allows the user to initially place a small diameter dilator cannula for passage of small diagnostic instruments. The dilator cannula can then be removed from the lumen of the dilator sheath while leaving the sheath inserted through the tissues. A larger diameter dilation cannula can then be inserted through the dilator sheath to create a larger port for passage of the larger operative instruments.
The device is assembled from medical grade materials under GMP conditions. Components are molded and machined by qualified suppliers. The components are assembled and secured by adhesives, welds, and mechanical interlocks. The Step® radially expanding access device is available in various lengths and working diameters to accommodate the selected size of indicated medical instruments. The subject product shall be available in both disposable and reusable forms.

§ 876.1500 Endoscope and accessories.
(a)
Identification. An endoscope and accessories is a device used to provide access, illumination, and allow observation or manipulation of body cavities, hollow organs, and canals. The device consists of various rigid or flexible instruments that are inserted into body spaces and may include an optical system for conveying an image to the user's eye and their accessories may assist in gaining access or increase the versatility and augment the capabilities of the devices. Examples of devices that are within this generic type of device include cleaning accessories for endoscopes, photographic accessories for endoscopes, nonpowered anoscopes, binolcular attachments for endoscopes, pocket battery boxes, flexible or rigid choledochoscopes, colonoscopes, diagnostic cystoscopes, cystourethroscopes, enteroscopes, esophagogastroduodenoscopes, rigid esophagoscopes, fiberoptic illuminators for endoscopes, incandescent endoscope lamps, biliary pancreatoscopes, proctoscopes, resectoscopes, nephroscopes, sigmoidoscopes, ureteroscopes, urethroscopes, endomagnetic retrievers, cytology brushes for endoscopes, and lubricating jelly for transurethral surgical instruments.
