Intended Use
The SoftFixTM Balloon Trocar have application in a variety of endoscopic procedures to provide a port of entry for endoscopic instruments into the body cavity of patients.
Device Story
The SoftFix Balloon Trocar is a sterile, single-use device designed to provide a port of entry for endoscopic instruments into the body cavity. It consists of an obturator and a cannula equipped with a seal system to maintain pneumoperitoneum. The device features an inflatable balloon and a manually movable bolster (fixation ring or fixation cone) to stabilize the cannula and minimize fascial trauma. The cannula includes a stopcock with a rotation valve for insufflation gas control and an inflation port for the balloon. It is used by clinicians during endoscopic procedures. The device is compatible with previously cleared Unimax Trocar Series obturators. The balloon and bolster mechanism anchors the cannula at the desired position, reducing migration during instrument manipulation.
Clinical Evidence
Bench testing only. No clinical data provided. Testing included biocompatibility (ISO 10993-5, -10), sterility validation (ISO 11135, ISO 11607-1), and bench performance testing (obturator insertion/removal, trocar penetration, cannula stabilization, air-leakage, balloon volume/rigidity, and fixation device retention).
Technological Characteristics
Sterile, single-use trocar. Materials: non-latex balloon. Components: cannula (housing with seal/valve, stopcock, inflation port), obturator, and fixation mechanism (ring or cone). Dimensions: 5.0-15.0 mm diameter, 70.0-100.0 mm length. Sterilization: EtO. Mechanical stabilization via inflatable balloon and movable bolster.
Indications for Use
Indicated for use in a variety of endoscopic procedures to provide a port of entry for endoscopic instruments into the body cavity of patients.

#### DEVICE DESCRIPTION 1.4.
The SoftFix™ Balloon Trocar is a series of sterile and single-use Trocar intended to be included as an extension to the previously cleared Unimax Trocar Series.
In general, the Trocars from Unimax Trocar Series consist of an Obturator and a Cannula containing a seal system. The Obturator is used to place the cannula through the incision site into the patient's body cavity where the Cannula remains anchored at a desired position. For that anchoring purpose, previously cleared Trocars belonging to the Unimax Trocar Series are equipped with threaded Cannulas or Cannulas with a movable bolster. As a series extension, the Cannulas belonging to the SoftFix™ Balloon Trocars are now available with an inflatable balloon and a manually movable bolster to provide stabilization and minimize the fascial trauma during an endoscopic procedure. Whereas these Cannulas are also designed to be compatible with the Obturators belonging to the previously cleared Trocars from the Unimax Trocar Series. The balloon and movable bolster combination on the cannula come with two options;
- a) "SoftFix™ Balloon Fixation Ring" combination
- b) "SoftFix™ Balloon Fixation Cone" combination
Similar to Cannulas of the Trocars from the Unimax Trocar Series, each Cannula of the SoftFix™ Balloon Trocars is a combination of a sleeve and a housing, fitted with a pair of seal and valve to maintain pneumoperitoneum when the Obturator or other laparoscopic devices are inserted or withdrawn through it during the surgical procedures. The Cannula also contains a stopcock with rotation valve at its proximal end in order to allow or prevent passage of any insufflation gas (e.g. CO2), when needed. Near the stopcock, the Cannula contains an inflation port to inflate/deflate the balloon using a standard syringe. While the movable "fixation ring" can be slid down the Cannula sleeve to adjust its height as well as fixing the Cannula at a desired position, the height of the "fixation cone" can be adjusted by pressing the thumb notch present on it and the Cannula can be anchored at the desired position by affixing fascial sutures on the struts present near the thumb notch.

### 1.7. CONCLUSION
The SoftFix™ Balloon Trocar has identical intended use with predicate devices as they act as port of entry for the endoscopic instruments into the patient body cavity. In addition to this, the devices incorporate similar Obturators into the Cannulas.
In conclusion, the abovementioned regulatory, technical as well as non-clinical testing summaries demonstrate that the SoftFix™ Balloon Trocar is as safe, as effective and perform as equivalent to the predicate devices and hence are found to be substantially equivalent.
