Intraline® Spiral S2938 PDO Threads for Clinics

The Intraline® S2938 spiral thread is a sterile PDO device for minimally invasive facial contouring and soft-tissue support. Clinics integrate this 29G platform into supervised thread-lift workflows, supported by US distribution for predictable lead times. Med Wholesale Supplies serves licensed clinics and healthcare professionals with authentic, brand-name medical products sourced through vetted distributors.

What Intraline Is and How It Works

This preparation is a polydioxanone (PDO) spiral, sometimes referred to as a screw-type thread. It is supplied ready for professional insertion with a single-use needle. The spiral geometry offers spring-like support within soft tissue. Over time, PDO is metabolized by hydrolytic pathways and is naturally resorbed by the body.

In clinical use, trained practitioners place the device into appropriate tissue planes consistent with their protocols. The coiled architecture can help provide three-dimensional scaffolding and localized lift. Tissue response to PDO may include temporary support while the material remains in situ, followed by gradual clearance.

Intraline Spiral S2938 aligns with a broader thread portfolio that includes mono, spiral, double spiral, and cog formats, allowing clinics to select the structure that best fits case goals. For overview browsing across sizes and configurations, see the Threads Category.

Professional Applications

Clinics often deploy this spiral format in facial contouring protocols where subtle volumetric support is desired. Typical applications include softening fine static lines, enhancing definition along contours, and augmenting tissue support in combination with other aesthetic modalities. The device can complement HA fillers, skin boosters, and energy-based procedures within multi-step treatment plans when used by trained personnel.

S2938 PDO threads can suit focused zones where a coiled profile is preferred for spring-like contact in compact placements. Teams may pair spiral and mono threads in layered approaches, or combine spiral with cog options for structural lift and contour refinement. For foundational background on thread mechanisms and planning, review What Are PDO Threads. For alternative spiral specifications, consider TS2638 Double Spiral when dual-coil design is preferred.

Key Features

• Spiral architecture: Twisted profile for spring-like soft-tissue support in compact planes.
• Biocompatible polymer: Polydioxanone (PDO) that is absorbable and widely used in medical suturing.
• Professional format: Single-use needle presentation to support aseptic handling and efficiency.
• Two length options: 38 mm and 50 mm variants to accommodate site-specific planning.
• Pack efficiency: Supplied as a 20-thread unit to streamline inventory rotations.
• Traceability: Unit and outer labels designed to support lot and expiry tracking by the clinic.
• 29G specification: PDO spiral threads 29G 38mm format aligns with compact placement strategies.

Benefits in Practice

Teams value how this spiral thread integrates with established aesthetic workflows. The coiled structure can help anchor within soft tissue, offering tactile feedback during placement. It can be layered with monos in fine-line zones, or combined with cogs where mechanical lift is prioritized.

Procedural flexibility supports case-by-case planning. Practitioners can select length based on target area and desired distribution. The sterile, single-use format reduces preparation steps and helps standardize setup. Inventory consolidation is straightforward with a 20-thread pack, aiding forecasting across session blocks and scheduled series.

Cohesion within a modular thread range also helps maintain training continuity. Teams that already use monofilament or cog formats can introduce spiral placements without disrupting clinical flow. When appropriate, pairing with skin conditioning programs or booster sessions can further align with clinic protocols. In larger treatment plans, this approach can reduce chair-time variability and improve scheduling predictability.

When discussing patient expectations, providers typically explain that PDO is absorbable and that outcomes relate to placement technique, tissue characteristics, and adjunct therapies. Adverse events may include transient erythema, edema, or bruising at insertion sites; these are usually self-limiting. As with all invasive procedures, practitioners follow aseptic technique and their facility’s safety standards.

Composition & Ingredients

Active material: Polydioxanone (PDO), a synthetic, biocompatible, and biodegradable polymer used in absorbable sutures and aesthetic thread systems.

Format: Spiral (screw-type) configuration on a single-use needle for professional insertion.

This product contains no added pharmacologic agents. The polymer is intended to be metabolized over time following professional implantation. Clinics integrating spiral threads alongside other modalities should consider interoperability with their existing protocols and device platforms. Where needed, teams can review product families across the portfolio via Brand Overview to align formats with technique preferences.

Packaging & Supply

Each unit contains 20 sterile spiral threads in the S2938 configuration. The pack reflects a 29G platform, with threads referenced at 38 mm and 50 mm lengths. Each thread is intended for single use. Packaging is designed for sterility and supports lot and expiry identification for clinic traceability. Inspect barriers before use and do not use if sterility is compromised.

Packs can be allocated to treatment plans that use small, consistent quantities per session, helping maintain parity across multiple appointments. Storage follows standard shelf-stable device conditions: protect from moisture, avoid direct sunlight, and keep within the manufacturer’s recommended temperature range. For clinics mapping inventory across spirals, monos, and cogs, complementary items such as T2650 Double and PCLA Screw 29G can round out case coverage.

For those comparing model families, Spiral S3038 offers an alternative gauge and may be selected when a different handling profile is preferred.

Ordering & Logistics

Licensed accounts can sign in to view contract tiers and place orders aligned with practice volume. New customers complete account verification before purchasing. This supports appropriate access to professional-use devices and helps maintain product integrity through vetted channels.

Scheduling considerations may include aligning inbound deliveries with treatment cycles and staff availability. For clinics standardizing on a 29G platform, Intraline Spiral S2938 29G 38mm references can help forecast usage by zone and by session count. Your facility’s receiving process should confirm intact packaging and reconcile lot details to your internal tracking.

Comparable Products

Clinics seeking a different coil profile or gauge may also consider TS2638 Double Spiral for dual-spiral architecture. Where a polycaprolactone-based screw is preferred, PCLA Screw 29G offers an alternative material platform.

Pricing & Access

Sign in to view current contract pricing and any volume-based tiers available to your account. Multi-unit purchasing can streamline replenishment across scheduled patient series. If you manage multiple locations, coordinated ordering can help consolidate receiving and reduce per-site paperwork.

Availability & Substitutions

Supply can vary by gauge and length. If your standard configuration is temporarily unavailable, consider compatible alternatives from the same class. Teams often substitute with mono or double-spiral types for specific zones, or adjust the number of threads to maintain the planned outcome. For a broader view of options, browse the Threads Category or review the Brand Overview. Confirm suitability with your clinical lead before substituting in active protocols.
