Technology

TissuePatchDural is manufactured by a team of dedicated and professional polymer chemists and technicians under class 7 (10,000) clean room conditions. State of the art characterisation and analysis techniques ensure only the highest quality product is released.

TissuePatchDural has a fused multilayer structure containing patented reactive polymers for chemical bonding to tissue surface, and a non-adhesive backing material for ease of handling and prevention of post-surgical adhesions. The patch remains in position until absorbed in about 50 days.


Compostion

TissuePatchDural

  1. Carboxylic acid groups for inital tack via electrostatic interactions

  2. Functionalised carboxylic acid groups for covalent chemical bonding

Tissue Surface

  1. Tissue surface rich in protein groups containing amine and other nucleophilic functionalities

 

Stage 1.

Application: Ready to use and easy to apply

  1. Moderate pressure applied for several seconds allows contact ashesive to hold TissuePatchDural onto tissue surface

 

Stage 2.

Rapid adhesion and sealing within 30 seconds

  1. Amide bonds form rapidly between TissuePatchDural and the tissue surface

  2. The patch is strongly adhered flush to the surface to seal the wound to prevent leaks of air, blood and/or fluid
