Cook Medical launches Hemospray for the treatment of nonvariceal upper gastrointestinal bleeds


Single-use device is delivered through the channel of an endoscope and sprayed toward the source of a bleed to create a stable mechanical barrier

Cook Medical has chosen the annual meeting of the British Society of Gastroenterology to introduce an innovative endoscopic spray for use in nonvariceal bleeds in the upper GI tract to the UK market.

Hemospray, which has undergone a clinical study and multiple evaluations, expands Cook Medical’s current line of haemostasis devices, achieving haemostasis with a proprietary inorganic powder. <.p>

A single-use device, it is delivered through the channel of an endoscope and sprayed toward the source of a bleed. When the powder comes in contact with blood, it absorbs water and forms a gel, which acts both cohesively and adhesively to create a stable mechanical barrier that adheres to and covers the bleeding site. It is a nonthermal, nontraumatic treatment modality for achieving haemostasis.

“Hemospray is an important and new therapy, which offers an additional treatment option for patients who suffer from bleeding lesions in the upper GI tract,” said Dr John Morris, consultant gastroenterologist at the Glasgow Royal Infirmary Hospital.

Current hemostasis therapies rely on thermal, mechanical or injection devices. These carry risks of damage to the surrounding tissue and also require that the device be precisely placed on the bleeding vessel. Hemospray is designed to minimise the risks associated with current therapies and without the precision required of other treatment modalities.

“Because these bleeds can be complicated, no treatment option represents the perfect solution, even Hemospray,” said Barry Slowey, vice president and global business leader for Cook Medical’s Endoscopy division. “However, we do feel that this new device gives clinicians another important tool for the care of their patients.”

A study conducted by lead investigators Professor Joseph Sung and Dr Sam Giday at the Chinese University of Hong Kong showed that Hemospray achieves acute hemostasis in peptic ulcers. Further clinical studies are currently being conducted with Hemospray across multiple sites in Canada, Europe, and Hong Kong. The results of these will be available in the coming months.
