Indications for Use

The PROFOUND MATRIX SYSTEM is intended for dermatological procedures, as follows: The MATRIX PRO applicator is indicated for general dermatological procedures for electrocoagulation and hemostasis. The SUBLATIVE RF applicator is indicated for dermatological procedures requiring ablation and resurfacing of the skin, and for the treatment of facial wrinkles. At higher energy levels greater than 62mJ/pin, the Sublative RF applicator is limited to Fitzpatrick Skin Types I-IV. The SUBLIME applicator is indicated for non-invasive wrinkle treatment. At higher energy levels, greater than 100 J/ cm3, the Sublime applicator is limited to Fitzpatrick Skin Types I-IV.

Device Story

Profound Matrix System is a multi-applicator electrosurgical device for dermatological procedures. It utilizes three applicators: Matrix Pro (bipolar RF microneedling for electrocoagulation/hemostasis), Sublative RF (bipolar RF for skin ablation/resurfacing/wrinkles), and Sublime (combined IR light and bipolar RF for non-invasive wrinkle treatment via bulk dermal heating). Operated by physicians in clinical settings, the system uses a touchscreen interface to adjust parameters like needle depth, RF energy, and power density. The Matrix Pro applicator features impedance-based energy control to deliver precise thermal doses. The device transforms electrical energy into thermal energy at the skin surface or within the dermis to stimulate tissue healing and collagen remodeling. Clinical benefits include improved skin appearance and wrinkle reduction. The system is intended for professional use.

Clinical Evidence

No clinical or animal studies were conducted. Substantial equivalence is supported by bench testing, including electrical safety (IEC 60601-1, 60601-1-2, 60601-2-2), biocompatibility (ISO 10993), software validation, and ex-vivo thermal damage evaluation on excised abdominal skin. Ex-vivo testing confirmed that the Matrix Pro produces thermal effects (collagen denaturation, fat cell membrane disruption) consistent with the predicate Infini device.

Technological Characteristics

System console with touchscreen interface. Applicators: Matrix Pro (49 microneedles, 1 MHz bipolar RF), Sublative RF (multi-electrode pin array, 1 MHz bipolar RF), Sublime (IR 700-2000 nm + 1 MHz bipolar RF). Materials: Biocompatible patient-contacting components per ISO 10993. Energy: Bipolar RF and IR. Connectivity: Standalone console. Sterilization: Sterile microneedle tips. Software: Controlled by impedance sampling for energy delivery.

Indications for Use

Indicated for dermatological procedures including electrocoagulation, hemostasis, skin ablation, resurfacing, and treatment of facial wrinkles. Sublative RF and Sublime applicators at higher energy levels are restricted to Fitzpatrick Skin Types I-IV.

INTENDED USE/INDICATION FOR USE The PROFOUND MATRIX SYSTEM is intended for dermatological procedures, as follows: {4}------------------------------------------------ ## 510(k) Summary — K211217 The MATRIX PRO applicator is indicated for general dermatological procedures for electrocoagulation and hemostasis. The SUBLATIVE RF applicator is indicated for dermatological procedures requiring ablation and resurfacing of the skin, and for the treatment of facial wrinkles. At higher energy levels greater than 62 mJ/pin, the Sublative RF applicator is limited toFitzpatrick Skin Types I-IV. The SUBLIME applicator is indicated for non-invasive wrinkles treatment. At higher energy levels greater than 100 J/cm³, the Sublime applicator is limited to Fitzpatrick Skin Types I-IV. ### DEVICE DESCRIPTION 7. The Profound Matrix System combines three existing technologies and applications for dermatological procedures. Each respective technology is used in one of the three applicators designed for the Profound Matrix System. These three applicators are named: Matrix Pro, Sublative RF and Sublime. The Matrix Pro applicator is designed to deliver bipolar, non-ablative radiofrequency energy through a 7x7 matrix/grid of sterile microneedles to the skin in a fractional manner. The microneedles can be set up to pulse a maximum of three depths during each insertion of the matrix/grid of microneedles with a maximum depth of up to 3.5mm. The Sublative RF applicator delivers bipolar radiofrequency (RF) to the skin surface viaan array of multi-electrode pin tips. The applicator delivers bipolar RF energy to the skin, which results in heating of demarcated spots to temperatures that ablate and resurface at contact points of the multi-electrode pins. The Sublime applicator uses a combination of an infrared (IR) light source and bipolar radiofrequency (RF) to bulk heat the dermis and affect dermal collagen in order to treat wrinkles. The bulk heating of the dermal layers refers to the gradual and gentle accumulation of heat with each additional pass performed. #### 8.
