The sheets lyophilized collagen heyedrator was cleared through the FDA 510(k) pathway on July 25, 1986. Manufactured by Pantheon Products, it is classified as a Class 1 device under product code HMP.

What It Is

The device is a lyophilized collagen sheet designed for rehydration and use in clinical settings. It functions as a biocompatible scaffold, primarily intended for use in embolization procedures as a liquid agent. The collagen is derived from porcine sources and processed to ensure safety and efficacy.

FDA-Cleared Indications

  • Use as an absorbable hemostatic material to assist in controlling bleeding when conventional methods are ineffective or impractical.
  • Use as an embolic material to promote occlusion of blood vessels when indicated.
  • Use only according to the cleared labeling, preparation instructions, and intended route of administration.

Clinical Applications

  • Adjunctive control of bleeding during surgical or interventional procedures.
  • Temporary or targeted vessel occlusion during embolization procedures.
  • Management of bleeding from small vessels or diffuse oozing when direct ligation or cautery is difficult.

Reported off-label uses

  • Collagen scaffold applications in wound-healing research and selected clinical settings.

Off-label use: these uses are reported in practice or the literature but are not part of the FDA-cleared indications. Physicians may use a cleared device off-label based on their medical judgment; the manufacturer may not promote off-label uses.

Evidence Summary

The available literature includes 10 peer-reviewed studies, with a mix of RCTs, prospective, and retrospective studies. The studies span from 2019 to 2025, focusing on the device's biocompatibility, wound healing potential, and antibacterial properties.

Reported Outcomes

Published studies report that the device demonstrates significant biocompatibility, with in vitro and in vivo tests showing minimal cytotoxicity and irritation. It has shown promise in wound healing applications, particularly when combined with antibacterial agents. The device's structural properties support its use as a scaffold in tissue engineering.

Safety Profile

Reported complications include minimal adverse reactions in biocompatibility tests, with no significant sensitization or irritation observed. The studies highlight the device's safety profile, particularly in controlled clinical environments.

Evidence Limitations

The evidence is limited by the small sample sizes and the early-stage nature of some studies. Further research is needed to explore long-term outcomes and the device's efficacy in diverse clinical scenarios. The current literature lacks large-scale RCTs to fully establish its clinical benefits.

Practical Considerations

  • The material is lyophilized and must be rehydrated and prepared according to the product labeling before use.
  • Collagen products may be derived from porcine tissue; review the labeling and patient history for relevant animal-protein sensitivity or allergy.
  • The appropriate amount, size, and preparation depend on the bleeding site, target vessel, delivery method, and intended use; the supplied FDA record does not provide detailed dimensions.
  • Do not inject or deliver the material into a vessel unless the specific product labeling authorizes that route and use.
  • MRI safety is not established from the provided FDA record. Because this is a collagen material rather than an active electronic implant, MRI concerns are generally related to associated markers, packaging, or other implanted materials; verify the current labeling.
