No
The device description clearly states it is a surgical instrument with physical components like a grip housing assembly, shaft, jaws, and knife, and it connects to a generator via a power cord. This indicates it is a hardware device, not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the ENSEAL X1 Tissue Sealers are for use during surgical procedures to cut, seal, grasp, and dissect tissue and vessels within the body.
- Device Description: The description details a surgical instrument designed for direct interaction with tissue and vessels during surgery.
- IVD Definition: In Vitro Diagnostics are medical devices intended to be used outside the body to examine specimens (like blood, urine, or tissue samples) to provide information for diagnosis, monitoring, or screening.
The ENSEAL X1 Tissue Sealers are surgical instruments used in vivo (within the living body) during surgical procedures, not for testing samples in vitro (outside the body).

Device Description
The ENSEAL X1 Tissue Sealer instrument is a sterile, single patient use surgical instrument to coagulate and transect vessels up to and including 7mm in diameter, tissue and/or vascular bundles. This device is for soft tissue only. The instrument consists of a grip housing assembly, a rotating shaft, a moveable jaw, and a knife. The instrument shaft can be rotated 360° to facilitate visualization and enable easy access to targeted tissue. The jaws are in a normally-opened position and can be partially or fully closed by squeezing the closing handle. The jaws are designed for grasping and holding targeted tissue when clamped. The ENSEAL X1 Tissue Sealer has separate seal and cut capabilities. The lower jaw of the ENSEAL X1 Tissue Sealer can be used in the open or closed position to deliver energy based on the electrode configuration and jaw design. Bipolar energy is delivered when the SEAL button or the MIN foot pedal is pressed. Pressing the CUT button advances the knife the length of the jaws to cut the targeted tissue. The power cord is permanently attached to the device and connects the instrument to the generator. The ENSEAL X1 Tissue Sealer instrument is designed for use exclusively with the Ethicon Generator G11 (GEN11) software version 2016-1 or later, packaged separately.
