Determination of Regulatory Review Period for Purposes of Patent 
Extension; TACK ENDOVASCULAR SYSTEM (4F, 1.5-4.5 MILLIMETERS)

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA or the Agency) has 
determined the regulatory review period for TACK ENDOVASCULAR SYSTEM 
(4F, 1.5-4.5 MILLIMETERS (MM)) and is publishing this notice of that 
determination as required by law. FDA has made the determination 
because of the submission of applications to the Director of the U.S. 
Patent and Trademark Office (USPTO), Department of Commerce, for the 
extension of a patent which claims that medical device.

DATES: Anyone with knowledge that any of the dates as published (see 
SUPPLEMENTARY INFORMATION) are incorrect must submit either electronic

Furthermore, any interested person may petition FDA for a determination 
regarding whether the applicant for extension acted with due diligence 
during the regulatory review period by August 12, 2024. See 
``Petitions'' in the SUPPLEMENTARY INFORMATION section for more 
information.

SUPPLEMENTARY INFORMATION:

I. Background

    The Drug Price Competition and Patent Term Restoration Act of 1984 
(Pub. L. 98-417) and the Generic Animal Drug and Patent Term 
Restoration Act (Pub. L. 100-670) generally provide that a patent may 
be extended for a period of up to 5 years so long as the patented item 
(human drug product, animal drug product, medical device, food 
additive, or color additive) was subject to regulatory review by FDA 
before the item was marketed. Under these acts, a product's regulatory 
review period forms the basis for determining the amount of extension 
an applicant may receive.
    A regulatory review period consists of two periods of time: a 
testing phase and an approval phase. For medical devices, the testing 
phase begins with a clinical investigation of the device and runs until 
the approval phase begins. The approval phase starts with the initial 
submission of an application to market the device and continues until 
permission to market the device is granted. Although only a portion of 
a regulatory review period may count toward the actual amount of 
extension that the Director of USPTO may award (half the testing phase 
must be subtracted as well as any time that may have occurred before 
the patent was issued), FDA's determination of the length of a 
regulatory review period for a medical device will include all of the 
testing phase and approval phase as specified in 35 U.S.C. 
156(g)(3)(B).
    FDA has approved for marketing the medical device TACK ENDOVASCULAR 
SYSTEM (4F, 1.5-4.5 MM). TACK ENDOVASCULAR SYSTEM (4F, 1.5-4.5 MM) is 
indicated for use in mid/distal popliteal, tibial, and peroneal 
arteries, ranging in diameter from 1.5 mm to 4.5 mm, for the repair of 
post percutaneous transluminal balloon angioplasty dissection(s).
    Subsequent to this approval, the USPTO received patent term 
restoration applications for TACK ENDOVASCULAR SYSTEM (4F, 1.5-4.5 MM) 
(U.S. Patent Nos. 9,974,670; 10,137,013; and 10,271,973) from Intact 
Vascular, Inc., and the USPTO requested FDA's assistance in determining 
the patents' eligibility for patent term restoration. In a letter dated 
January 18, 2023, FDA advised the USPTO that this medical device had 
undergone a regulatory review period and that the approval of TACK 
ENDOVASCULAR SYSTEM (4F, 1.5-4.5 MM) represented the first permitted 
commercial marketing or use of the product. Thereafter, the USPTO 
requested that FDA determine the product's regulatory review period.

II. Determination of Regulatory Review Period

    FDA has determined that the applicable regulatory review period for 
TACK ENDOVASCULAR SYSTEM (4F, 1.5-4.5 MM) is 1,203 days. Of this time, 
1,010 days occurred during the testing phase of the regulatory review 
period, while 193 days occurred during the approval phase. These 
periods of time were derived from the following dates:
    1. The date an exemption for this device, under section 520(g) of 
the Federal Food, Drug, and Cosmetic Act (FD&C Act) (21 U.S.C. 
360j(g)), became effective: December 26, 2016. The applicant claims 
that the investigational device exemption (IDE) required under section 
520(g) of the FD&C Act for human tests to begin became effective on 
December 22, 2016. However, FDA records indicate that the IDE was 
determined substantially complete for clinical studies to have begun on 
December 26, 2016, which represents the IDE effective date.
    2. The date an application was initially submitted with respect to 
the device under section 515 of the FD&C Act (21 U.S.C. 360e): October 
1, 2019. The applicant claims September 30, 2019, as the date the 
premarket approval application (PMA) for TACK ENDOVASCULAR SYSTEM (4F, 
1.5-4.5 MM) (PMA P190027) was initially submitted. However, FDA records 
indicate that PMA P190027 was submitted on October 1, 2019.
    3. The date the application was approved: April 10, 2020. FDA has 
verified the applicant's claim that PMA P190027 was approved on April 
10, 2020.
    This determination of the regulatory review period establishes the 
maximum potential length of a patent extension. However, the USPTO 
applies several statutory limitations in its calculations of the actual 
period for patent extension. In its applications for patent extension, 
this applicant seeks 271 days, 348 days, or 442 days of patent term 
extension.

III. Petitions

    Anyone with knowledge that any of the dates as published are 
incorrect may submit either electronic or written comments and, under 
21 CFR 60.24, ask for a redetermination (see DATES). Furthermore, as 
specified in Sec.  60.30 (21 CFR 60.30), any interested person may 
petition FDA for a determination regarding whether the applicant for 
extension acted with due diligence during the regulatory review period. 
To meet its burden, the petition must comply with all the requirements 
of Sec.  60.30, including but not limited to: must be timely (see 
DATES), must be filed in accordance with Sec.  10.20, must contain 
sufficient facts to merit an FDA investigation, and must certify that a 
true and complete copy of the petition has been served upon the patent 
applicant. (See H. Rept. 857, part 1, 98th Cong., 2d sess., pp. 41-42, 
1984.) Petitions should be in the format specified in 21 CFR 10.30.
    Submit petitions electronically to https://www.regulations.gov at 
Docket No. FDA-2013-S-0610. Submit written petitions (two copies are 
required) to the Dockets Management Staff (HFA-305), Food and Drug 
Administration, 5630 Fishers Lane, Rm. 1061, Rockville, MD 20852.
