Indications for Use
The D-Stat Dry Silver and D-Stat Dry Clear Silver are applied topically as an adjunct to manual compression and are indicated for the control of surface bleeding from vascular access sites and percutaneous catheters or tubes and reducing the time-to-hemostasis in patients undergoing diagnostic endovascular procedures utilizing 4-6 Fr. introducer sheaths. D-Stat Dry Silver and D-Stat Dry Clear Silver contain silver chloride to prevent microorganisms commonly encountered in the clinical setting from colonizing on the pad. The D-Stat Dry Wrap Silver hemostatic bandage and Thrombix Silver Hemostasis Patch are applied topically as an adjunct to manual compression and are indicated for the control of surface bleeding from vascular access sites and percutaneous catheters or tubes. D-Stat Dry Wrap Silver and Thrombix Silver contain silver chloride to prevent microorganisms commonly encountered in the clinical setting from colonizing on the pad.
Device Story
Non-woven gauze pads lyophilized with procoagulant (thrombin, calcium chloride, sodium carboxymethylcellulose) and antimicrobial (silver chloride) components; applied topically by clinicians as adjunct to manual compression at vascular access sites. Pad creates physical barrier; thrombin facilitates hemostasis via enzymatic conversion of fibrinogen to fibrin. Silver chloride releases ionic silver in presence of blood/wound fluids to prevent microbial colonization on pad. Single-use; sterilized via electron-beam irradiation. Benefits include physical hemostasis and antimicrobial protection of the dressing itself.
Clinical Evidence
Bench, in vitro, and in vivo testing. Biocompatibility per ISO 10993 (non-cytotoxic, non-sensitizing, non-irritant). Acute topical laceration study in porcine model showed time-to-hemostasis for D-Stat Dry Silver did not exceed D-Stat Dry (no silver). Antimicrobial testing (AATCC 100-2004) showed >4 log reduction in microbial population after 24 hours; Zone of Inhibition testing demonstrated comparable performance to silver-containing predicates.
Technological Characteristics
Non-woven gauze pad; lyophilized thrombin, calcium chloride, sodium carboxymethylcellulose; silver chloride antimicrobial. Sterilized by electron-beam irradiation. Single-use. No software or electronic components.
Indications for Use
Indicated for control of surface bleeding from vascular access sites and percutaneous catheters/tubes; adjunct to manual compression. D-Stat Dry Silver/Clear Silver also indicated for reducing time-to-hemostasis in patients undergoing diagnostic endovascular procedures using 4-6 Fr. introducer sheaths.

#### Intended Use
The D-Stat Dry Silver and D-Stat Dry Clear Silver are applied topically as an adjunct to manual compression and are indicated for the control of surface bleeding from vascular access sites and percutaneous catheters or tubes and reducing the time-to-hemostasis in patients undergoing diagnostic endovascular procedures utilizing 4-6 Fr. introducer sheaths. D-Stat Dry Silver and D-Stat Dry Clear Silver contain silver chloride to prevent microorganisms commonly encountered in the clinical setting from colonizing on the pad.
The D-Stat Dry Wrap Silver hemostatic bandage and Thrombix Silver Hemostasis Patch are applied topically as an adjunct to manual compression and are indicated for the control of surface bleeding from vascular access sites and percutaneous catheters or tubes. D-Stat Dry Wrap Silver and Thrombix Silver contain silver chloride to prevent microorganisms commonly encountered in the clinical setting from colonizing on the pad.
#### Device Description
The D-Stat Dry Silver, D-Stat Dry Clear Silver, D-Stat Dry Wrap Silver and Thrombix Silver products are non-woven gauze pads lyophilized (frecze-dried) with procoagulant (thrombin, calcium chloride and sodium carboxymethylcellulose) and antimicrobial (ionic silver water) components. The D-Stat Drv/Wrap/ Thrombix pad creates a physical barrier to blood flow and facilitates hemostasis by the physiological coagulation-inducing properties of the lyophilized pad combined with compression. The

lyophilized components (including thrombin) facilitate hemostasis through enzymatic cleavage and conversion of fibrinogen to fibrin. These products contain silver chloride to prevent microorganisms commonly encountered in the clinical setting from colonizing on the pad and have not been clinically tested for their ability to reduce local infection, catheter-related bloodstream infections (CRBSI) and skin colonization of microorganisms commonly related to CRBSI .
In the presence of fluids (i.e., blood and wound fluids), ionic silver is released from the silver chloride to prevent microorganisms commonly encountered in the clinical setting from colonizing on the pad. Ionic silver, an atom of silver that is missing one electron, provides the antimicrobial property by altering the protein structure and preventing bacterial cells from carrying out normal functions. The D-Stat Silver products demonstrated an antimicrobial effect in AATCC Test Method 100-2004 and Zone of Inhibition laboratory testing.
An adhesive foam or clear bandage accompanies some products in the family. All products are sterilized by electron-beam irradiation and are intended for single use only.
#### Summary of Studies
The bench, in vivo and in vitro testing and results that specifically support the substantial equivalence determination of the subject device to the predicates are tests for thrombin activity, pH, moisture content, wetting time, product conformability, silver content, biocompatibility, hemostatic effectiveness, and antimicrobial activity (AATCC Test Method 100-2004 and Zone of Inhibition). The subject device met all established specifications in the design verification bench testing. Biocompatibility tests satisfying ISO 10993 demonstrated the device was non-cytotoxic, not a significant sensitizer and a negligible irritant, which confirms the D-Stat Silver products are biocompatible. Statistical evaluation of data from an acute topical laceration study in a porcine model showed the time-to-hemostasis for the D-Stat Dry Silver did not exceed the time-to-hemostasis for the D-Stat Dry (no silver). Antimicrobial testing demonstrated that after 24 hours of contact with representative D-Stat Silver test samples, all seven microorganism cultures, including some antibiotic resistant cultures, had greater than a 4 log reduction in microbial population under AATCC Test Method 100-2004 and zone of inhibition testing demonstrated comparable zones between D-Stat Silver and the silver-containing predicate devices.
# Statement of Equivalence
The D-Stat Silver products are similar in indications for use and design to currently marketed topical hemostats and wound dressings. Technological differences between the subject and predicate devices were sufficiently addressed through bench, in vivo and in vitro testing and no new safety or performance issues were raised during biomaterial or design verification testing. As such, the D-Stat Dry Silver products (D-Stat Dry Silver, D-Stat Dry Clear Silver, D-Stat Dry Wrap Silver and Thrombix Silver) can be considered substantially equivalent to the predicate devices.
