Cook Medical launches spray device for treating upper GI bleeds
22 July 2013
Cook Medical has launched in the UK market its Hemospray device,
a powder delivery system that stops bleeding in the upper
Hemospray is a single-use device, 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
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.
“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.
Acute upper gastrointestinal bleeding (UGIB) is associated with
over 4,000 deaths a year. Current hemostasis therapies rely on
thermal, mechanical or injection devices. These devices 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
minimize 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 Prof. 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.
For doctors wishing to use Hemospray at their hospital, training
can be provided at over 20 centres countrywide in the UK.
