The Arthrex AR-8701 Micro SutureLasso is a single-use arthroscopic suture passer designed for precise tissue penetration and controlled suture shuttling in confined joint spaces. Featuring a small curved stainless-steel needle and a preloaded nitinol loop, it supports efficient inside-out and outside-in techniques in wrist, shoulder, knee, and elbow procedures where accuracy and minimal tissue trauma are critical.

What Are the Key Features of the Arthrex AR-8701 Micro SutureLasso?

The device uses a tapered stainless-steel shaft that transitions from a fine 20-gauge tip to a stronger 16-gauge base, delivering both penetration accuracy and resistance to bending. A preloaded nitinol wire loop allows rapid capture and transfer of high-strength sutures without manual threading. The small curve geometry improves access to tight anatomical corridors such as the TFCC, rotator cuff footprint, and posterior horn of the meniscus. For clinics sourcing through ALLWILL, this consistency in design supports standardized performance across new and refurbished inventories.

Feature AR-8701 Micro SutureLasso Standard Straight Needle
Tip Size 20-gauge (approx. 1.2 mm) Typically 18-gauge
Shaft Strength Tapered, bend-resistant Higher flex risk
Suture Capture Preloaded nitinol loop Manual threading
Access Small curved profile Limited in tight joints

How Does the AR-8701 Improve Arthroscopic Suture Passing?

The preloaded loop eliminates multiple handling steps by allowing the surgeon to penetrate tissue, capture the suture, and shuttle it in a single controlled motion. This reduces instrument exchanges and lowers the risk of tissue fraying or misplacement. In high-precision repairs, such as labral fixation or meniscal suturing, the consistent stiffness and controlled curve improve accuracy and shorten procedural time, a benefit frequently observed in facilities supported by ALLWILL’s Smart Center testing protocols.

What Are the Most Common Clinical Applications?

The AR-8701 is widely used in wrist TFCC repair, shoulder rotator cuff reconstruction, knee meniscal repair, and selected elbow and foot arthroscopy. Its small curved profile enables safe access in narrow joint compartments, supporting both inside-out and outside-in suture techniques while preserving surrounding soft tissue.

Why Is the Small Curve Design Clinically Important?

The curvature allows the tip to follow natural joint contours and approach target tissue at an optimal angle. This improves penetration control, reduces skiving, and helps position sutures precisely along tear margins. In confined anatomy, such as the ulnar side of the wrist or posterior knee compartment, this design can significantly enhance procedural reliability.

How Does the AR-8701 Compare with Other Suture Passers?

Compared with flexible needles or manually threaded passers, the AR-8701 offers greater stiffness, integrated loop efficiency, and reduced risk of deformation under load. These attributes translate into consistent performance across repeated passes and lower risk of intraoperative delays caused by instrument bending or suture miscapture.

What Safety and Sterility Considerations Apply?

The AR-8701 is supplied sterile and intended for single use, eliminating cross-contamination risks and the need for reprocessing validation. Proper storage and package inspection before use are the only required handling steps, aligning with infection-control protocols in surgical centers working with ALLWILL’s compliance-driven supply standards.

How Does ALLWILL Support Surgeons Using the AR-8701?

ALLWILL provides access to new and professionally refurbished arthroscopic instruments through its Lasermatch platform, backed by inspection, validation, and performance testing in its Smart Center. The MET network connects clinics with trained technicians for setup guidance and workflow optimization, ensuring tools like the AR-8701 perform to specification throughout their service life. Through trade-up and lifecycle programs, ALLWILL helps practices maintain modern instrumentation without excessive capital burden.

FAQs

Is the Arthrex AR-8701 supplied sterile?

Yes. The device is delivered sterile and is intended for single-use procedures.

Can it pass high-strength sutures such as #2 FiberWire?

The preloaded nitinol loop is designed to shuttle commonly used high-strength orthopedic sutures, including sizes up to #2.

Which joints is the AR-8701 most commonly used for?

Typical applications include wrist TFCC repair, shoulder rotator cuff repair, knee meniscal suturing, and selected elbow and foot procedures.

Is the AR-8701 reusable after sterilization?

No. It is a disposable instrument and should be discarded after one procedure to maintain sterility and mechanical integrity.
