Providing Clear Control


PuraStat is a synthetic haemostatic material in the form of a prefilled syringe.
PuraStat is indicated for haemostasis in the following situations encountered during surgery, when haemostasis by ligation or standard means is insufficient or impractical1:

  • Bleeding from small blood vessels and oozing from capillaries of the parenchyma and surrounding tissues of solid organs
  • Oozing from vascular anastomoses to native or artificial vessels, on the surface of blood vessels and surrounding tissues
  • Bleeding from small vessels and oozing from capillaries of the GI tract and surrounding tissues
    • Reduction of delayed bleeding following gastrointestinal endoscopic submucosal dissection (ESD) procedures in the colon

PuraStat Technology

The matrix is formed from synthetic peptides which are composed of three naturally occurring amino acids in a sequence which is repeated 4 times. The peptides self-assemble to form a 3 dimensional matrix upon a change in pH2 caused by exposure to an ionic solution such as blood, peritoneal fluid or other bodily secretions.

Product Advantages

PuraStat mimics extra cellular matrix

The peptides in PuraStat are synthetized in a specific sequence which provide the molecule with shape memory to enable them to self assemble into a scaffold which mimics human extra cellular matrix (ECM).

Based on results of scanning electron microscopy, the structure of PuraStat self-assembling peptide hydrogel is understood to be a network of fibres with a diameter of around 10–20 nm and pores with a diameter of about 50–200 nm that resembles the mesh structure of natural collagen.

PuraStat does not swell1

In internal testing PuraStat does not swell after implantation or during the resorption process. This is because unlike other hydrogels which are designed to absorb water as part of their breakdown cycle, PuraStat is broken down by enzymatic action.

As PuraStat doesn’t swell it will not cause compression of underlying tissues of structures, or prevent that natural physiologic dilatation of vessels.

PuraStat = No Assembly or Preparation

PuraStat is delivered in a prefilled syringe, just connect the applicator using the luer and the product is ready to use.

PuraStat has been demonstrated to achieve complete haemostasis in less than 15 seconds.1

Revolutionary Bleeding Control

The trigger for the peptides in PuraStat to begin self assembly is a change in ionic charge. PuraStat is acidic so when in contact with more alkaline liquids the reduction in ionic charge causes the rapid self assembly of β-sheets. The β-sheets then transition to form a complex network of fibres with a diameter of around 10–20 nm and pores with a diameter of about 50–200nm that resembles the mesh structure of natural collagen1. The formation of this complex fibre network rapidly seals the bleeding point leading to haemostasis.

PuraStat is 100% Synthetic

PuraStat contains no glutaraldehyde.

The peptides are made from chemically synthesized amino acids to guarantee the final product is contamination free. The amino acids are bonded together in a specific sequence at a 2.5% concentration in aqueous solution to make PuraStat.1

PuraStat is Resorbed in 30 Days1

PuraStat is broken down by the actions of enzymes which break down the peptide scaffold into the constituent amino acids over approximately 30 days.1 The amino acids are metabolised by the body or excreted if they are surplus to requirements.

Breakdown Component
A conditionally essential amino acid, it plays an important role in cell division, the healing of wounds, removing ammonia from the body, immune funciton, and the replease of hormones
A nonessential amino acid, meaning it can be manuratured by the human body, hence need not be obtained directly through diet. Alanine is found in a wide variety of foods
Asparatic Acid
An acidic amino acid that is a constituent of most proteins and also occurs in sugar cane. It is important in the metabolism of nitrogen in animals and also acts as a neurotransmitter

PuraStat is Suturable & Clipable

Because PuraStat is a liquid hydrogel, it is largely composed of water and remains completely flexible once applied. Because it does not harden or cure it remains soft and can easily be sutured through should the need arise.

This also means that you can place surgical or endoscopic clips directly through a layer of PuraStat, this is very helpful if using PuraStat to clearly identify bleeding points when bleeding is more profuse or persistent.

PuraStat Will Not Migrate1

PuraStat is naturally viscous. When in contact with blood the change in pH causes the self assembly of PuraStat> to occur rapidly at the interface between it and the bleeding point, gaining further integral strength as the reaction occurs. Any PuraStat not incorporated in the final clot will separate and may be left in situ.

Mode of Action

Applying PuraStat is simple

PuraStat is a haemostat existing of a nanofiber network structure that requires no preparation. This means it is ready to apply straight from packet to patient.
To apply PuraStat is just as easy, simply deploy PuraStat at the base of the lesion and wait, following the instructions below:

  • Remove as much blood as possible from haemorrhagic site.
  • Apply an adequate quantity of PuraStat to the haemorrhagic site.
  • The nozzle should be as close as possible to the bleeding point.
  • Do not disturb the self-assembled PuraStat gel until sufficient time has been allowed for haemostasis to occur.
  • If necessary, repeat the application of PuraStat several times until haemostasis is achieved.
  • After haemostasis is confirmed, excess PuraStat may be left in place.

PuraBond is a synthetic haemostatic material in the form of a prefilled syringe, filled with a clear, aqueous peptide solution. PuraBond is part of the RADA16 family of products, alongside PuraStat. Contact between the product and liquids such as blood leads to the formation of fibres in the aqueous solution, yielding a peptide hydrogel. The hydrogel quickly coats the point of bleeding and, by physically closing the superficial part of the broken blood vessel, causes blood coagulation in the deeper part of the vascular wall, resulting in haemostasis.


PuraShield is a synthetic haemostatic material for ENT surgery. A ready-to-use, slightly viscous hydrogel, composed of self-assembling peptides (SAPs) founded by the Massachusetts Institue of Technology (MIT), whilst undergoing tissue regeneration research. PuraShield is licenced in Spain as a medical device for use in Ears, Nose, Throat, Head and Neck surgeries.
PuraShield has many advantages which lend it to being a suitable bleeding management solution for FESS, adult tonsillectomies, thyroidectomies and amongst many other types of surgery. PuraShield's composition mimics the human extracellular matrix, and it does not cause swelling of the tissue. Its transparency and viscosity ensure precise control while maintaining visibility during the surgery, even in the event of working in small and narrow spaces.
