LIGATION BAND DISPENSING CAP ASSEMBLY AND METHODS OF USE

摘要

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.

主权项

1. A cap configured to be disposed at a distal end of an endoscope, the cap comprising:
a proximal portion configured to accommodate at least one ligation band on an outer surface thereof; a distal portion, tapering towards a distal end thereof, the distal portion including an outer surface having a pattern formed thereon, the pattern having one or more portions having a first frictional coefficient and one or more portions having a second frictional coefficient different than the first frictional coefficient, configured to facilitate rolling motion of the ligation band thereon; and a cavity extending between the distal portion and the proximal portion.
