Group/Cohort Intervention/treatment
Hemospray to treat lower GI bleeds Device: Hemospray
The Hemospray™ device comes in a 7F kit and a 10F kit. Each kit includes two 220 cm Teflon application catheters, a handle with CO2 cartridge and a syringe containing approximately 20 g of the Hemospray™ material. Hemospray™ is a proprietary inorganic mineral powder that acts as a mechanical barrier when sprayed over a bleeding lesion and the surrounding mucosa.

Primary Outcome Measures :
  1. Percentage of device related adverse events [ Time Frame: 30 days ]

Secondary Outcome Measures :
  1. Percentage of recurrent bleeding that occurs outside the blood vessel [ Time Frame: 30 days ]
  2. Percentage of hemostasis of lower GI bleeds originating from multiple sources [ Time Frame: 30 days ]
  3. All cause mortality [ Time Frame: 30 days ]
    Mortality within 30 days of index procedure
