An adaptor and adaptor kit are described in which the adaptors may be configured to be removably coupled to a working channel of an endoscope system, such as a hysteroscope system. The adaptors may include an elongate body having a central lumen extending between a distal end and a proximal end of the elongate body, and a bend along a length of the elongate body between the distal and proximal ends. The adaptors may be configured to accommodate variations in patient anatomy, such as variations in the size and shape of a uterus, and location of the ostia to the fallopian tubes. A plurality of non-identical adaptors having a number of different characteristics may be sold in a kit so that particular adaptor can be selected for use with a particular patient anatomy.
