A tissue collector (70) comprising a cannula (12) adapted for insertion into a uterus, the cannula (12) including a flexible distal portion (18), and at least one guide wire (74) attached to the distal portion (18) of the cannula (12), wherein movement of the at least one guide wire (74) flexes the distal portion (18) of the cannula (12). There is also provided a suction device (100) comprising a syringe (102) including a distal barrel (104) which extends from a proximal barrel (106), the proximal barrel (106) having a larger diameter than the distal barrel (104), a plunger element (112) disposed inside the proximal barrel (106), the plunger element (112) being adapted to sealingly slide inside the proximal barrel (106), and a plunger (108) that passes through the plunger element (112), wherein when the plunger (108) is pulled proximally and starts to enter the proximal barrel (106), the plunger (108) is received in a recess (113) formed in the plunger element (112), such that when the plunger (108) is pulled further proximally, the plunger (108) moves together with the plunger element (112) and the plunger element (112) serves as a new distal end of the plunger (108) during sliding travel in the proximal barrel (106). |
