HEMORRHAGE MANAGEMENT SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18586901 titled 'HEMORRHAGE MANAGEMENT SYSTEM

The abstract describes a wound dressing comprising a shape memory polymer (SMP) foam with open cells in two states, and a hydrogel included within the cells. The composite can be positioned near hemorrhagic tissue with the SMP foam in the first state, then expanded to the second state against the tissue when the SMP foam is plasticized at 37°C.

• Shape memory polymer (SMP) foam with open cells
• Hydrogel included within the cells
• Composite can be positioned near hemorrhagic tissue
• SMP foam transitions between first and second states
• Expansion of composite against tissue at 37°C

Potential Applications: - Wound dressings for hemorrhagic tissue - Medical devices for controlled tissue expansion

Problems Solved: - Effective wound dressing for hemorrhagic tissue - Controlled expansion of dressing against tissue

Benefits: - Improved wound healing - Controlled and targeted treatment - Enhanced patient comfort

Commercial Applications: - Medical device industry - Healthcare sector - Research and development in wound care

Questions about the technology: 1. How does the shape memory polymer foam transition between states? 2. What are the advantages of using a hydrogel in wound dressings?

Frequently Updated Research: - Ongoing studies on the effectiveness of shape memory polymer foams in wound care - Research on the potential applications of hydrogels in medical devices

Overall, this innovative wound dressing technology offers a promising solution for effective wound care and tissue expansion in medical applications.

Original Abstract Submitted

An embodiment includes a wound dressing comprising: a shape memory polymer (SMP) foam, including open cells, having first and second states; and a hydrogel (HG) included within the cells; wherein (a) in a first position a composite, including the SMP foam and the HG, is configured to be located proximate a hemorrhagic tissue with the SMP foam in the first state; (b) in a second position the composite is configured to be expanded to the second state against the hemorrhagic tissue when the SMP foam is plasticized at 37° C. depressing a glass transition temperature (T) of the SMP foam to below 25° C. Other embodiments are described herein.
