Abstract: A medical device for resecting a tissue. The medical device includes an elongate shaft having a distal end, a proximal end, and a plurality of channels extending therebetween. The medical device also includes a cap assembly disposed at the distal end of the elongate shaft. The cap assembly includes a housing having a proximal portion, a distal portion, and a cavity extending therebetween. The housing is configured to be transparent and includes a friction surface pattern disposed over a portion of an outer surface of the housing. The cap assembly further includes one or more ligation bands disposed on the proximal portion of the housing. The cap assembly also includes a wire interwoven between the ligation bands. The wire is further configured to roll at least one ligation band at a time towards the distal end of the distal portion.
