Indications for Use

The JRP Wound Spreader is a non-invasive superficial wound retractor with an integrated guard that is used for wound care and positioning of small superficial wounds in the skin of up to 1/4" in width, 1/4" in depth and 1/2" in length.

Device Story

JRP Wound Spreader is a manual, handheld, non-invasive superficial wound retractor; features four tensioning fingers with integrated guard. Operator places fingers on skin astride wound; pushes device distally to create surface friction, pulling skin taut to improve visualization. Device barrel acts as sway stabilizer; allows observation of wound. Integrated guard accommodates needleless syringe for wound flushing; operator applies downward pressure to create seal, then depresses syringe plunger. Used in clinical settings for small superficial wounds. Benefits include non-invasive wound positioning and facilitated flushing without entering wound site.

Clinical Evidence

Bench testing and a 40-person human factors/performance study. Study comprised 160 performance and assembly tasks with a 97% success rate. Mechanical testing confirmed luer slip fit connection integrity under pressure (100% success). No clinical patient outcome data reported.

Technological Characteristics

Materials: Medical grade acrylic (tubes/disk) and Type 316 stainless steel (tensioning fingers). Fingers are passivated. Components joined with medical grade adhesive. Form factor: Handheld, tubular assembly with four tensioning fingers and luer slip connection for syringe. Sterile. Non-powered, manual operation.

Indications for Use

Indicated for wound care and positioning of small superficial skin wounds (max 1/4" width, 1/4" depth, 1/2" length).

# 510(k) Summary K152538

### Physical Characteristics:

For wound positioning only, the tensioning fingers at the distal end of the device are placed against the skin, astride the wound. Using one hand to grasp the barrel of the JRP Wound Spreader, the device is pushed distally towards the wound. causing the retractor fingers to move away from the wound. The friction of the fingers against the skin effects the positioning of the wound so as to improve visualization. If flushing is desired, the above method is modified for use with a syringe by using one hand to grasp the barrel and apply downward pressure until the distal surface contacts the skin, providing an envelope for flushing of the positioned wound via the attached syringe through the discharge port of the spreader assembly. The plunger of the syringe may then be depressed using the second hand. In this operation, the Wound Spreader barrel functions secondarily as a sway stabilizer and is clear and colorless, allowing the operator to observe the procedure.

### Performance Characteristics:

As the JRP Wound Spreader is applied against the skin as described above, the fingers meet the skin first. The coils enhance the spring action of these fingers, allowing them to move gently outward, pulling the skin slightly taut. This spring action applies tension across the wound and maintains wound position without entering into the wound. However, the operator must maintain the downward pressure in order to maintain wound positioning.

### Intended Use:

The JRP Wound Spreader is a non-invasive superficial wound retractor with an integrated guard that is used for wound care and positioning of small superficial wounds in the skin of up to 1/4" in width, 1/4" in depth and 1/2" in length.

### Material and Manufacturing Process:

The device consists of three standard-sized acrylic tubes and an acrylic disk fabricated from standard medical grade material. The device also makes use of tensioning fingers made from medical grade Type 316 stainless steel. For the final marketed product, the tensioning fingers will be passivated prior to assembly. The tubular parts and retractor arms are cut to size and qlued with medical grade adhesive at contact surfaces. All manufacturing and assembling will be conducted in accordance with cGMP requirements. This unit will be manufactured sterile.

## 510(k) Summary K152538

## Comparisons Summary and Technical Characteristics of the JRP Wound Spreader Compared to the Predicate Device the Endo Retract II:

Both the JRP Wound Spreader and the Endo Retract II make use of an array of tensioning fingers which are positioned on and against the skin to form, shape, open and position a wound or incision. Both devices also maintain the wound or incision position open for a desired procedure by use of pressure against the skin. The JRP Wound Spreader has the same intended use to position wounds or incisions as the predicate device and utilizes materials that are already in use in other medical devices. No new issues of safety are introduced by using this device. The JRP Wound Spreader design and effectiveness are addressed here and through performance and safety testing as sited in the submission. This device is found to have no new safety issues because the arms used for deformation at the wound site do not enter the wound. The JRP Wound Spreader is topical and non-invasive compared to the predicate device. While the principle mechanism of action is the same for both devices, i.e., the application of tension across the wound, the JRP Wound Spreader employs a surface friction method to apply this tension, in contrast to the predicate device, which employs outward pressure directly against the edges of the wound. While the predicate retractor is indicated for lengthy surgical procedures involving wounds and incisions, the invasive nature of its action makes it unsuitable for use in small superficial topical wounds to the skin. Conversely, JRP Wound Spreader's design limits its use solely to the care of superficial wounds to the skin. Additionally, the JRP Wound Spreader's design facilitates the flushing of the indicated wound.

### Performance Testing:

Several tests were performed and confirmed that the luer slip fit connection to the syringe is secure and does not leak under pressure. Also a twisting and flexion test to the luer connection confirmed a substantial bond. The 40-person study comprised of 160 performance and assembly tasks as sited in our submission was 97% successful and indicated that the JRP Wound Spreader is effective in positioning wounds compared to the predicate device and presented no new safety issues supporting a determination of substantial equivalence.

## Summary Conclusion:

The JRP Wound Spreader and the Endo Retract II both position and maintain the positioning of wounds and incisions by use of an array of small retractor fingers which make use of an outward projection applied against the skin. The effective history of the Endo Retract II is evident. The JRP Wound Spreader was designed to open small wounds and incisions, position and maintain positioning in a totally non-invasive topical manner using the same basic method as the Endo Retract II does invasively. Both the performance and the safety of the JRP Wound Spreader are qualified and

quantified by the 40-person study involving 160 tasks (performance, safety and assembly) with a 97% success rate. Several tests were also conducted to the luer slip fit syringe connection, applying higher than normal pressure to the connection with a 100% success outcome. The testing, engineering and design logic dictate that the JRP Wound Spreader is substantially equivalent to the Endo Retract II in performance with no new safety issues.
