Key Innovations

  • The core of the system is an implantable device housing that contains a bobbin (spool) and drive assembly, which holds the threads of the sling or graft under tension.

See Video

  • Through rotation of the bobbin - actuated via a shaft and gear assembly - the length of the sling threads  and tension can be adjusted even after implantation.

See Video

  • Threads can be wound (tightened) or unwound (relaxed), allowing postoperative fine-tuning of urethral support without re-operation.

  • The design aims for a low-profile, compact housing to minimize bulk and maximize patient comfort.

Components & Mechanics

01

Sling or Graft + Threads

  • The system supports the use of either a synthetic mesh sling or an autologous (patient-derived) fascial graft, offering flexibility per surgical preference or patient needs.
  • Threads attached to the sling/graft pass through the implant housing and wrap around the internal bobbin.

02

Bobbin & Drive Assembly

  • The bobbin inside the housing winds (or unwinds) the threads to change sling tension.
  • The drive assembly, composed of a shaft and gear assembly, transfers rotational motion to the bobbin. A cycloidal drive is used to achieve a high gear ratio in a compact form.

Adjustment Tool Interface

  • Once intraoperatively ideal tension is reached, threads may be locked via an internal screw or locking mechanism, securing the sling in its final position.
  • The overall disc-shaped, flat design keeps the implant low-profile, minimizing discomfort or risk of device migration.

04

Thread Locking & Final Fixation

  • A detachable external tool can engage with the shaft through an access port in the housing to rotate and regulate tension.
  • Adjustments are intended to be done in the office-setting during the early postoperative period.

OPUS Sling: Expanding Possibilities Beyond Fixed Slings

Challenge With Fixed Slings: How the Adjustable System Solves It

  • Sling position/tension set only at surgery - it may be suboptimal after swelling subsides or tissue shifts.
  • Risk of overtensioning or undertensioning. Once implanted, there is no easy way to correct issues without additional revision surgery.
  • Limited material options. ALL fixed slings are made of mesh-only materials

Advantages of OPUS Sling System

  • Fine incremental adjustments allow the surgeon to optimize tension to the “sweet spot”, avoiding overtensioning or undertensioning
  • Non-invasive in-office adjustments can reduce or eliminate the need for reoperation.
  • Supports both synthetic and autologous graft materials - more flexibility for patient mesh/tissue choice. 

Typical Use Workflow

1. Implantation

  • A sling or graft is positioned beneath the mid-urethra (bladder neck in men) using a standard surgical approach.
  • Threads of the sling are routed through tissue via retropubic approach and into the device housing.

2. Initial Tensioning

3. Postoperative Adjustment Period

4. Final Lock-In

5. Long-Term Stability

Advantages of This Technology for Patients & Surgeons

  • Personalized continence control/adjustments tailored to individual healing and anatomy.

  • Reduced need for revision surgery due to suboptimal sling tension/position.

  • Mesh-Optional and autograft-compatible addressing concerns of synthetic mesh use in certain patients.

  • Low-Profile implant improves comfort and reduces foreign-body sensation.

  • Higher success in complex or recurrent SUI cases, in both women and men, with higher patient satisfaction
