The purpose of this observational case series is to assess the use of Corplex P as a resorbable particulate device used to cover, protect, and provide a moist wound environment when added to the standard of care treatment of hard-to-heal wounds.

This is a retrospective, single-center observational case series to assess real-world outcomes of StimLabs dehydrated human umbilical cord particulate used in the management of hard-to-heal wounds, including acute and chronic ulcers. This case series will include real-world data from up to 10 subjects at one participating site. The Corplex P product has been utilized in a variety of patients attending wound clinics for management of partial and full-thickness wounds, pressure ulcers, venous leg ulcers (VLU), diabetic foot ulcers (DFUs), chronic vascular ulcers, and surgical wounds. The device is intended to cover, protect, and provide a moist wound environment. Medical records will be reviewed for subjects who received the Corplex P product, and data will be collected from baseline, first presentation, treatment, and follow up data. Data summaries will review wound closure, percent are reduction in wound size over treatment time, number of device applications required during treatment, time to wound closure, and adverse events.

Inclusion Criteria:

• All consecutive subjects that received a Corplex P device application during wound management in the following retrospective cohort between February 2024 and November 2025.

Exclusion Criteria:

• Subjects not receiving an initial Corplex P application during treatment
