Intended Use

The STARRT System is indicated for use as a secondary diagnostic tool for the further evaluation of women previously diagnosed with proximal tubal occlusion by hysterosalpingography or selective salpingography. The STARRT System is only designed to access the proximal portion of the fallopian tube, i.e. the first 2-3 cm. It should only be advanced as far as necessary to achieve a meaningful study, recognizing that possible adverse effects of more distal advancement, particularly upon normal tubes, have not yet been determined. The STARRT System is not intended for tubal recanalization, and there is no data available, in particular, pregnancy data, showing clinical benefit for this use. Studies are underway. The STARRT System is not to be used for gamete or embryo transfer, or other assisted reproduction techniques. The STARRT System should only be used by clinicians with experience in tubal evaluation.

Device Story

Stargate Falloposcopy Catheter is a single-lumen device used within the STARRT Falloposcopy System for diagnostic imaging of the proximal fallopian tube (first 2-3 cm). The device features a diamond-shaped wire tip at the distal end to guide the catheter and displace tubal epithelium from the falloposcope lens, optimizing visualization. It is delivered transcervically through a Coaxess Catheter positioned at the tubal ostium via a rigid hysteroscope. Operated by clinicians experienced in tubal evaluation, the device provides visual feedback to assist in diagnosing tubal health. The system includes a trifurcated irrigation tubing set for fluid infusion to clear the field of vision. Clinical benefit is derived from improved diagnostic accuracy compared to previous catheter iterations.

Clinical Evidence

Clinical testing validated device performance, with clinicians reporting improved diagnosis of tubal health compared to the predicate VS Catheter. Preclinical safety was established via a rabbit fallopian tube catheterization histology study, which showed no significant difference in tubal damage between catheterized and control tubes.

Technological Characteristics

Single-lumen catheter with graded shaft flexibility and a diamond-shaped wire tip at the distal end. Includes a trifurcated irrigation tubing set for fluid infusion. Designed for use with a falloposcope and guidewire. Mechanical design focuses on navigation and visualization optimization within the proximal fallopian tube.

Indications for Use

Indicated for women previously diagnosed with proximal tubal occlusion via hysterosalpingography or selective salpingography. Contraindicated for tubal recanalization, gamete/embryo transfer, or other assisted reproduction techniques.

Regulatory Classification

Identification

A hysteroscope is a device used to permit direct viewing of the cervical canal and the uterine cavity by a telescopic system introduced into the uterus through the cervix. It is used to perform diagnostic and surgical procedures other than sterilization. This generic type of device may include obturators and sheaths, instruments used through an operating channel, scope preheaters, light sources and cables, and component parts.

Device Names

| Trade Name: | Stargate™ Falloposcopy Catheter and Trifurcated Irrigation Tubing Set (part of STARRT™ Falloposcopy System) |

| Common Name: | falloposcopy catheter and irrigation tubing |
| Classification Name: | Uterotubal carbon dioxide insufflator and accessories (per 21 CFR 884.1300) |

Device to Which Substantial Equivalence was Claimed

Substantial Equivalence for the Stargate Falloposcopy Catheter was claimed to the

Conceptus VS™ Catheter which, as part of the STARRT Falloposcopy System, was previously cleared for the diagnosis of Proximal Tubal Occlusion (PTO). Substantial Equivalence for the Trifurcated Irrigation Tubing was claimed to the Clarus Medical, Model 5150 Tubing Set which was previously cleared for fluid infusion for clearing the field of vision with endoscopes.

Device Description

The Conceptus Stargate Catheter is a single lumen device with a graded shaft flexibility. The distal end has a diamond shaped wire tip designed to guide the catheter and to keep fallopian tube epithelium away from the falloposcope lens during imaging. The hub located at the proximal end of the Conceptus Stargate Catheter has two ports. The sideport is used for the attachment of the Trifurcated Irrigation Tubing set. The endport serves as a conduit for the introduction of the Conceptus Falloposcopy Guidewire and Falloposcope.

#### Device Description, cont.

The Conceptus Stargate Catheter and Falloposcopy Guidewire are transcervically delivered into the fallopian tube ostium through the lumen of the Coaxess™ Catheter which is delivered into the uterine cavity through the working channel of a rigid hysteroscope and positioned at the tubal ostium under hysteroscopic guidance. The Conceptus Stargate Catheter and Falloposcopy Guidewire are designed for use within the proximal portion of the fallopian tube (the first 2-3 cm of the tube).

#### Intended Use

The Stargate Catheter as part of the STARRT Falloposcopy System is intended for use as a secondary diagnostic tool for further evaluation of women previously diagnosed with proximal tubal occlusion by hysterosalpingography or selective salpingography.

## Technological Characteristics

The Conceptus Stargate Catheter is substantially equivalent to the Conceptus VS Catheter and will replace that device in the Conceptus STARRT Falloposcopy System. The primary difference between the Stargate Catheter and VS Catheter is a diamond shaped wire which has been added to the distal tip of the Stargate Catheter. The primary purpose of the wire tip is to keep tubal epithelium away from the falloposcope lens to optimize imaging of the fallopian tube lumen.

### Data Supporting Substantial Equivalence

Conceptus conducted laboratory, preclinical and clinical testing to confirm that the Stargate Catheter is safe and effective. The laboratory testing demonstrated that small forces are applied to the wire tip during clinical use. Laboratory testing further demonstrated that the force required to advance the Stargate Catheter is no greater than the force required to advance the VS Catheter. Lastly, laboratory testing confirmed that the Stargate Catheter is less likely to kink as compared to the VS Catheter.

A fallopian tube catheterization histology study in rabbits was conducted to demonstrate the safety of the Stargate Catheter. The objective of the study was to use the rabbit model to determine if fallopian tube catheterization as well as anticipated adverse events cause damage to the fallopian tube and if there is any resulting adverse impact on pregnancy rates. Study results demonstrate that their is no significant difference in fallopian tube damage between the catheterized and control tubes.

Lastly, clinical testing was conducted to validate the performance of the device. Participating clinicians reported that they were able to make a better diagnosis of tubal health with the Stargate Catheter as compared to the VS Catheter.
