Inclusion criteria

* The subject is able to understand and sign Informed Consent Form * The subject is between 18-85 years of age. * The subject has (symptomatic) Grade 2-3 Hemorrhoids and is eligible for stapled hemorrhoidopexy

Exclusion criteria

* The procedure is needed as revision hemorrhoid surgery. * Any female patient, who is pregnant, suspected pregnant, or nursing. * The participant has an active or a history of infection requiring antibiotics at the intended operative site within thirty (30) days prior to the planned surgery date. * The participant is unable or unwilling to comply with the study requirements, follow-up schedule. * The participant has a 1 year history of drug or alcohol abuse. * The participant has a history of venous thrombosis or pulmonary embolism. * The participant has a history of coagulopathy. * The participant has taken aspirin, anti-coagulation and/or anti platelet therapies (e.g. Warfarin, Lovenox) within 7 days prior to the planned date of surgery. * The participant has a history of fecal incontinence * The participant has had injection therapy, infrared laser treatment or rubber band ligation for treatment of hemorrhoids within 1 month of screening * The participant has co-morbidities which, in the opinion of the investigator, will not be appropriate for the study.
