How It Works

When Hemospray comes in contact with an actively bleeding site, the powder absorbs water, then acts both cohesively and adhesively, forming a mechanical barrier over the bleeding site.

Formation of Barrier

“I find this noncontact hemostatic approach especially helpful when the bleeding is diffuse and the tissue fragile, such as in malignancies. I believe it is the most effective agent available today to produce immediate hemostasis”<br />

A Different Approach to Hemostasis

Hemospray, unlike traditional therapies, is a nonthermal, nontraumatic, noncontact modality that doesn’t require the precise targeting of other endoscopic devices.

Anticipated Advantages

Nonthermal
No tissue changes occur as sometimes experienced with thermal modalities.
Noncontact
Aerosol delivery system eliminates the need for direct mechanical or contact forces with the treatment site by the delivery system.
Nontraumatic
Since no force is applied at the treatment site, the powder minimizes the risk of tissue trauma as experienced with other modalities.
Nonspecific Targeting
Powder is sprayed toward the source of the bleed, so it does not require the en face approach and the precise targeting of other modalities.

When To Use Hemospray

Hemospray is a different endoscopic modality that has demonstrated successful results in a wide range of nonvariceal upper gastrointestinal bleeds.
