Yes
The device is used to guide the placement of a voice prosthesis for tracheoesophageal voice restoration, and it also contains a voice prosthesis device intended for voice rehabilitation after laryngectomy. Voice restoration and rehabilitation are therapeutic purposes.
No
The device, the FirstFit Surgical Kit (FFSK), is indicated for surgical creation of a tracheoesophageal puncture, dilation of the wall, and guiding voice prosthesis placement. Its function is to facilitate a surgical procedure for voice restoration, not to diagnose a condition.
No
The device description clearly outlines a kit containing physical components like needles, guidewires, and a voice prosthesis, which are hardware.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are used to provide information for diagnosis, monitoring, or screening.
- Device Function: The Blom-Singer® FirstFit™ Surgical Kit is a surgical tool used during a surgical procedure to create and prepare a passage (tracheoesophageal puncture) and guide the placement of a voice prosthesis. It is a physical device used directly on the patient's anatomy.
- Lack of Sample Analysis: The description does not mention the device analyzing any biological samples from the patient. Its function is mechanical and procedural.
Therefore, the Blom-Singer® FirstFit™ Surgical Kit falls under the category of a surgical device or implant, not an in vitro diagnostic.

Device Description
The FirstFit Surgical Kit (FFSK) is a kit for creating a primary or secondary TE puncture, with subsequent dilatation of that puncture to a width that facilitates placement of the included Blom-Singer® Indwelling Voice Prosthesis, cleared in K082206.
The FFSK is for transient use as an aid to a surgical operation to puncture and stent the tracheoesophageal septum. The FFSK is provided sterile (by ethylene oxide) in a sealed tray, ready to be introduced into the surgical field. Additionally, it is used to guide voice prosthesis placement in a total laryngectomized patient as a primary or secondary procedure. Puncture and placement should take place in a sterile field with the patient being under anesthesia.
The FFSK is designed for primary or secondary tracheoesophageal puncture (TEP) with retrograde voice prosthesis insertion. This kit includes: one (1) 13-gauge curved core puncture needle, one (1) 36-inch guidewire with rounded tips, one (1) pharynx protector tool with handle and notched cylinder, one (1) voice prosthesis inserter pre-loaded with a Blom-Singer® Indwelling Voice Prosthesis of the diameter and length specified on the package label.
The Blom-Singer® Indwelling Voice Prosthesis devices (VP) are indwelling devices primarily made of silicone, designed to provide voicing after total laryngectomy. The voice prostheses are placed in a surgically created fistula between the trachea and esophagus in order to divert air through the prosthesis valve to create voicing. The use of an indwelling device means that routine removal for cleaning by the patient is not necessary, thus making it easier for the patient to maintain the device the risk of accidental dislodgment of the device.

The FFSK contains a sterile single use indwelling Blom-Singer® Indwelling Voice Prosthesis device intended for voice rehabilitation after surgical removal of the larynx (laryngectomy). Cleaning of the voice prosthesis is performed by the patient while it remains in situ.
PATIENT POPULATION
For patients who had their larynx surgically removed.
COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE
The FirstFit Surgical Kit (FFSK) is a convenience kit for creating a primary or secondary TE puncture, with subsequent dilatation of that puncture to a width that facilitates placement of the included Blom-Singer® Indwelling Voice Prosthesis, cleared in K082206.
Biocompatibility testing
The biocompatibility evaluation for the FFSK was conducted in accordance with the FDA guidance, Use of International Standard ISO-10993, 'Biological Evaluation of Medical Devices Part 1: Evaluation and Testing, May 1, 1995, and International Standard ISO 10993-1 Biological Evaluation of Medical Devices – Part 1: Evaluation and Testing Within a Risk Management Process, as recognized by FDA.
Performance Testing
The following testing was performed according to:
- . Sterilization
- Sterilization method: Ethylene Oxide O
- Validation method: overkill approach (half-cycle method) per ISO 11135, ISO 10993-7, о ISO 14937
- . Shelf Life
- Shelf life by accelerated aging- per ASTM F1980-21 (Accelerated Aging of Sterile Barrier O Systems for Medical Devices)
- O Packaging Validation - Visual Inspection (per ASTM F1886), Burst Test (per ASTM F1140), Dye Penetration (per ASTM F1929), Peel Strength Testing (per TM-061)
- Biocompatibility - EN ISO 10993-1
- Bench testing - per internal protocols
- o Usability engineering IEC 62366-1: Cadaver Study was performed under simulated-use conditions with 15 users performing 2 punctures & placements each on fresh cadaver tissue as a usability validation testing methodology for the FirstFit Surgical Kit to ensure the subject device can accommodate:
- an anterograde tracheoesophageal puncture (TEP) (primary & secondary), O
6
- a TEP dilation to allow for placement of 16Fr, 20Fr, & 22.5Fr voice prostheses O
- a retrograde voice prosthesis insertion in the TEP (primary & secondary) During the study O 3 out of 37 cadavers needed additional instrumentation for dilation to complete the placement of the voice prostheses. This result was indicative of post-mortem changes in cadaveric anatomy where it is no longer alive and has undergone significant changes due to the death and preservation by freezing process, including potential tissue stiffening, which could lead to difficulty dilating the tissue. This is supported in Hohmanna et al, 2018 that suggests fresh-frozen cadaver tissue exhibits a higher modulus (55.3MPa) of elasticity/stiffness compared to fresh tissue (25.6MPa) as observed in cadaveric long bicep tendons, which may suggest frozen cadaveric tissue used in our cadaver study exhibited a higher stiffness than what would be observed in a live patient.
The study concluded users can effectively place the FirstFit Surgical Kit with no tissue damage (ripping, tearing, etc.) during puncture and dilation of the tracheoesophageal wall and placement of the voice prosthesis.
Animal Studies
No animal data submitted.
Clinical Studies
No clinical data submitted.
CONCLUSIONS
Based on the study result and as a precaution, the FFSK's labelling has been updated to include a warning to "proceed with great care and abort the procedure if dilation of the TE puncture requires too much force". The addition of this waring aligns with the predicate's labeling.
The FFSK labeling also includes an additional recommendation for how to proceed if the procedure needs to be abandoned mid-way after the puncture has been created and dilated.
The physician must determine if the patient's tissue or anatomy is eligible for safe use of this kit as suggested by the contraindications, warnings, and precautions of our Instructions for Use either prior to procedure or during.
Freudenberg Medical believes the additional warning and recommendation for how to proceed certain cases, combined with the performance testing demonstrate that the subject device is substantially equivalent to the predicate.
