The STRATAFIX™ Spiral PDS™ Plus Knotless Tissue Control Devices are indicated for use in soft tissue approximation where the use of absorbable sutures is appropriate.
STRATAFIX™ Spiral PDS™ Plus Knotless Tissue Control Devices are antibacterial monofilament, synthetic absorbable devices consisting of dyed (violet) polyester, poly(p-dioxanone), the empirical molecular formula of which is (C4H6O3)X. The devices contain IRGACARE® MP (triclosan), a broad spectrum antibacterial agent, at no more than 2360 μg/m. The pigment for the violet dye is D&C Violet No. 2. Polydioxanone polymer has been found to be nonallergenic, nonpyrogenic and elicits only a slight tissue reaction during absorption.
The STRATAFIX™ Spiral PDS™ Plus Knotless Tissue Control Devices are available in Unidirectional and Bidirectional forms:
-
The STRATAFIX™ Spiral PDS™ Plus Unidirectional Knotless Tissue Control Devices consists of barbed suture material, armed with a surgical needle on one end and a fixation loop at the opposite end. The STRATAFIX™ Spiral PDS™ Plus Unidirectional Knotless Tissue Control Device is designed to anchor with a closed loop at one end and a unidirectional barbed section on the other end. Barbs are oriented in one direction to allow tissue approximation without the need to tie surgical knots.
-
The STRATAFIX™ Spiral PDS™ Plus Bidirectional Knotless Tissue Control Device consists of barbed suture material, armed with a surgical needle on each end. The device also contains an un-barbed center transition zone that facilitates the initiation of the device use. The barbs allow for tissue approximation without the need to tie surgical knots.
While the formation of barbs in the STRATAFIX™ Spiral PDS™ Plus Devices reduce the tensile strength relative to non-barbed suture material of the same size, tying of knots in non-barbed suture materials also reduces their effective strength. For this reason, the strength of the STRATAFIX™ Spiral PDS™ Plus Devices can be compared to USP knot strength of non-barbed sutures. Additionally, USP designations for diameter are used to describe the STRATAFIX™ Spiral PDS™ Plus Devices suture material after barbing, except for minor variation in suture diameter with a maximum overage of 0.1 mm.

Polydioxanone polymer has been found to be nonallergenic, nonpyrogenic and elicits only a slight tissue reaction during absorption.
The STRATAFIX™ Spiral PDS™ Plus Knotless Tissue Control Devices are available in Unidirectional and Bidirectional forms:
-
The STRATAFIX™ Spiral PDS™ Plus Unidirectional Knotless Tissue Control Devices consists of barbed suture material, armed with a surgical needle on one end and a fixation loop at the opposite end.

The device also contains an un-barbed center transition zone that facilitates the initiation of the device use. The barbs allow for tissue approximation without the need to tie surgical knots.
While the formation of barbs in the STRATAFIX™ Spiral PDS™ Plus Devices reduce the tensile strength relative to non-barbed suture material of the same size, tying of knots in non-barbed suture materials also reduces their effective strength. For this reason, the strength of the STRATAFIX™ Spiral PDS™ Plus Devices can be compared to USP knot strength of non-barbed sutures. Additionally, USP designations for diameter are used to describe the STRATAFIX™ Spiral PDS™ Plus Devices suture material after barbing, except for minor variation in suture diameter with a maximum overage of 0.1 mm.
Indications for Use:
The STRATAFIX™ Spiral PDS™ Plus Knotless Tissue Control Devices are indicated for use in soft tissue approximation where the use of absorbable sutures is appropriate.
The indications for use are identical between the subject and predicate devices.

Comparison of Technological Characteristics with the Predicate Devices:
There are no changes to the technological characteristic of the STRATAFIX™ Spiral PDS™ Plus Knotless Tissue Control Devices. The subject devices differ from their respective predicate devices only in the Instructions for Use (IFU). The Instructions for Use of the subject devices are updated with the following change:
Ethicon will remove the warning related to use in gastrojejunal anastomoses for Roux-en-Y gastric bypass in the IFU for STRATAFIX™ Spiral PDS™ Plus Knotless Tissue Control Devices.
Guidance for Industry and Food and Drug Administration Staff: The 510(k) Program: Evaluating Substantial Equivalence in Premarket Notifications [510(k)] has been followed and it was determined that subject Devices are substantially equivalent to the predicate in that they share:
a) the same fundamental scientific technology,
b) the same intended use,
c) the same design,
d) the same materials,
e) equivalent packaging materials and configuration,
f) the same labeling components
g) the same sterilization process (Ethylene Oxide)
h) the same sterility assurance level (SAL) is 10-6.
Performance Data:
A retrospective chart review of hospital electronic medical records was performed to support the update of the STRATAFIX Spiral PDS™ Plus Knotless Tissue Control Devices warning, evaluating robotically-assisted hand-sewn gastrojejunal anastomosis for Roux-en-Y gastric bypass (RYGB) using STRATAFIX Spiral Knotless Tissue Control Devices (KTCD).
A total of 145 patients met the selection criteria for the robotically-assisted hand-sewn gastrojejunal anastomosis cohort. Their demographics are shown in Table 1. There was no inpatient mortality at index and no anastomotic leakage, anastomotic bleeding, bleeding of unspecified origin, or intra-abdominal infection within 30 days post-procedure. There were no cases of reoperations. Three patients (2.1%) experienced anastomotic stricture, which was resolved on follow-up.
Taken together, we believe there is sufficient evidence to justify the removal of the warning statement regarding their use in gastrojejunal anastomoses for Roux-en-y gastric bypass.

§ 878.4493 Absorbable poly(glycolide/l-lactide) surgical suture.
(a)
Identification. An absorbable poly(glycolide/l-lactide) surgical suture (PGL suture) is an absorbable sterile, flexible strand as prepared and synthesized from homopolymers of glycolide and copolymers made from 90 percent glycolide and 10 percent l-lactide, and is indicated for use in soft tissue approximation. A PGL suture meets United States Pharmacopeia (U.S.P.) requirements as described in the U.S.P. “Monograph for Absorbable Surgical Sutures;” it may be monofilament or multifilament (braided) in form; it may be uncoated or coated; and it may be undyed or dyed with an FDA-approved color additive. Also, the suture may be provided with or without a standard needle attached.(b)
Classification. Class II (special controls). The special control for this device is FDA's “Class II Special Controls Guidance Document: Surgical Sutures; Guidance for Industry and FDA.” See § 878.1(e) for the availability of this guidance document.
