DESCRIPTION The EMBLEM S-ICD subcutaneous electrode insertion tool (the "EIT") is a component of the Boston Scientific S-ICD System, which is prescribed for patients when cardiac arrhythmia management is warranted. The EIT is used to create a subcutaneous tunnel to facilitate implantation of the EMBLEM S-ICD subcutaneous electrode.
Component compatibility. All Boston Scientific S-ICD implantable components are designed for use with the Boston Scientific or Cameron Health S-ICD System only. Connection of any S-ICD System components to a non-compatible component will result in failure to deliver life-saving defibrillation therapy.
When the electrode insertion tool is received, it is sterile provided the container is intact. If the packaging is wet, punctured, opened, or otherwise damaged, return the electrode insertion tool to Boston Scientific. • Use by date. Use the electrode insertion tool before or on the USE BY date on the package label because this date reflects a validated shelf life.
Implantation • Creating the subcutaneous tunnel. Use the electrode insertion tool to create the subcutaneous tunnel when implanting and positioning the subcutaneous electrode. Avoid tunneling close to any other subcutaneously implanted medical devices or components, for example, an implantable insulin pump, drug pump, or ventricular assist device.

Figure 1. Placement of the S-ICD System (Model 3501 Electrode shown) Creating the Device Pocket The device is implanted in the left lateral thoracic region. To create the device pocket, make an incision such that the device can be placed in the vicinity of the left 5th and 6th intercostal spaces and near the mid-axillary...
Figure 2. Creating the Device Pocket Implanting the EMBLEM S-ICD Subcutaneous Electrode The procedure described below is one of several surgical approaches that can be used to appropriately implant and position the electrode. Alternate surgical approaches could be considered if system placement requirements can be achieved.

Make a small, 2 cm horizontal incision at the xiphoid process (xiphoid incision). The size and orientation may vary at the physician’s discretion based on the patient’s body habitus. NOTE: If desired, in order to facilitate attachment of the suture sleeve to the fascia following electrode placement, two suture ties to the fascia can be made at the xiphoid incision prior to continuing.

Using conventional suture material, tie the anchoring hole of the subcutaneous electrode to the EIT, creating a long 15-16 cm loop (Figure 3 Connecting the Distal End of the Subcutaneous Electrode to the EIT on page 11).

With the subcutaneous electrode attached, carefully pull the EIT back through the tunnel to the xiphoid incision until the proximal sensing electrode emerges. If using S-ICD Subcutaneous Electrode Model 3401, place a suture sleeve over the subcutaneous electrode shaft 1 cm below the proximal sensing electrode. Using the preformed grooves, bind the suture sleeve to the subcutaneous electrode shaft using 2-0 silk or similar non-absorbable suture material, making sure not to cover the proximal sensing electrode.

Make a second incision approximately 14 cm superior to the xiphoid incision (superior incision). If desired, place the exposed subcutaneous electrode on the skin to make this measurement. The distance between the superior and xiphoid incisions must accommodate the portion of the subcutaneous electrode from the distal sensing electrode to the proximal sensing electrode.

Once the distal tip of the EIT emerges from the superior incision, disconnect and retain the suture loop from the distal tip of the EIT. Secure the ends of the suture with a surgical clamp. Remove the EIT. Using the secured suture at the superior incision, carefully pull the suture and subcutaneous electrode through the tunnel until the anchoring hole emerges.
Page 22
At the superior incision, secure the anchoring hole to the fascia using the pre-placed sutures from step 6 (Figure 5 Anchoring the Distal Tip of the Subcutaneous Electrode on page 16). Figure 5. Anchoring the Distal Tip of the Subcutaneous Electrode NOTE: Ensure that the suture is securely fastened to fascia by gently tugging on the suture prior to tying to the subcutaneous electrode anchoring hole.
Page 23
Gently tug the subcutaneous electrode at the superior incision to ensure the anchoring hole is secured to the fascia. To dispose of the EIT, return the used product to the original package, then dispose in a biohazard container. To avoid air entrapment and ensure good tissue contact with the implanted subcutaneous electrode, flush all incisions with sterile saline solution and apply firm pressure along the electrode to expel any residual air out through the incisions prior to closing.
