Intended Use
The Ultraflex ™Precision™ Colonic Stent is indicated for palliative treatment of colonic strictures in the descending colon, sigmoid colon and rectum caused by malignant neoplasms.
Device Description
The proposed Ultraflex™ Precision™ Colonic Stent System consists of a self-expanding metal stent and a delivery catheter. The proposed stent consists of Nitinol wires wound together to form a cylinder with a flared distal section. The proposed stent is mounted on a delivery catheter. The stent is compressed onto the tapered delivery catheter shaft and bound with braided nylon suture using a crochet stitch. The stent is deployed by holding the handle stationary and pulling a ring to unravel the crochet stitch. The proposed stent diameter is 25mm along the body and 30mm at the flared distal section; the lengths are 6cm, 9cm, and 12cm.

No
The device description and performance studies focus on the mechanical properties and deployment mechanism of a physical stent, with no mention of software, algorithms, or data processing that would indicate AI/ML.

Yes
The device is described as a colonic stent used for palliative treatment of strictures, which falls under the scope of therapeutic intervention.

No
The device is a stent used for palliative treatment of colonic strictures, which is a therapeutic rather than a diagnostic function.

No

The device description clearly states that the device consists of a self-expanding metal stent and a delivery catheter, which are physical hardware components.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health. These tests are performed outside of the body.
  • Device Description and Intended Use: The Ultraflex™ Precision™ Colonic Stent is a physical device that is implanted into the body to treat colonic strictures. It is a therapeutic device, not a diagnostic one. It does not perform any tests on samples.

The information provided clearly describes a medical device used for treatment within the body, which is the opposite of an in vitro diagnostic.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Comparative performance testing was performed, where appropriate, between the proposed Ultraflex Precision Colonic Stent System and the Bard Memotherm Colorectal Stent System to establish substantial equivalence. Additional performance data, such as tensile strength, fatigue, and corrosion resistance testing was also performed.

In vivo testing of the proposed Ultraflex Precision Colonic Stent System demonstrates that the device is safe and effective for its intended use.

SECTION 11 510(K) SUMMARY

510(K) SUMMARY

1. Submitter:

Boston Scientific Corporation One Boston Scientific Place Natick, MA 01760-1537

Contact: Kathleen Morahan, RAC Regulatory Affairs Manager Date Prepared: March 10, 2003

2. Device:

Trade Name: Ultraflex™ Precision™ Colonic Stent System Common Name: Expandable, metallic colonic stent Classification Name: Not classified

3. Predicate Device:

C.R. Bard Memotherm® Colorectal Stent

4. Device Description:

The proposed Ultraflex™ Precision™ Colonic Stent System consists of a self-expanding metal stent and a delivery catheter. The proposed stent consists of Nitinol wires wound together to form a cylinder with a flared distal section. The proposed stent is mounted on a delivery catheter. The stent is compressed onto the tapered delivery catheter shaft and bound with braided nylon suture using a crochet stitch. The stent is deployed by holding the handle stationary and pulling a ring to unravel the crochet stitch.

6. Technological Characteristics:

The proposed Ultraflex™ Precision™ Colonic Stent System is a Nitinol, self-expanding stent mounted on a delivery catheter. The proposed stent diameter is 25mm along the body and 30mm at the flared distal section; the lengths are 6cm, 9cm, and 12cm.

The Ultraflex™ Precision™ Colonic Stent System is substantially equivalent to C.R. Bard's Memotherm Colorectal Stent. The devices have intended use and are both self-expanding stents constructed of Nitinol. Both stents are mounted on a delivery catheter, however the delivery catheter designs differ. The proposed Ultraflex™ Precision™ Colonic stent is bound onto the delivery catheter shaft with braided nylon suture using a crochet stitch. The predicate Memotherm Colorectal stent delivery catheter utilizes a co-axial tube and the stent is constrained onto the delivery catheter shaft by the outer sheath.

7. Performance Data:

The use of self-expanding metal stents for palliation of malignant colorectal strictures is well documented in the literature.

Comparative performance testing was performed, where appropriate, between the proposed Ultraflex Precision Colonic Stent System and the Bard Memotherm Colorectal Stent System to establish substantial equivalence. Additional performance data, such as tensile strength, fatigue, and corrosion resistance testing was also performed.

In vivo testing of the proposed Ultraflex Precision Colonic Stent System demonstrates that the device is safe and effective for its intended use.

8. Conclusion:

BSC has demonstrated that Ultraflex Precision Colonic Stent System is substantially equivalent to C.R. Bard's currently marketed Memotherm® Colorectal Stent.

Dear Ms. Morahan:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drue, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (sections 531-542 of the Act); 21 CFR 1000-1050.
