Abstract: A morcellator (1) for morcellating tissue within a body cavity of a patient is provided in combination with first (17) and second (18) tissue-pulling devices, and an insert (19). The morcellator (1) comprises a handle portion (2) having a lumen (6) passing therethrough, and an aperture (10) communicating with the proximal end of the lumen. A tube (3) extends from the handle portion and has a tissue cutting device (7) located at the distal end of the tube. The handle includes first (11) and second (12) valves associated with the lumen of the handle portion, and the first and second tissue-pulling devices have shafts of a first diameter and second diameter respectively. The insert (19) comprises a stem (21) and a body portion (20), the stem being received in the aperture (10) to form a substantially gas-tight seal in combination with the first valve (11).

Abstract: The present invention relates to a medicament delivery device in which the medicament to be delivered is stored within a cartridge having a displaceable piston therein. The displaceable piston is driven to expel medicament by way of a lead screw that is advanced and retracted by way of a suitable drive mechanism. A guideway through which the lead screw travels is provided. However, in known devices the guideway is held in position by other components of the apparatus. Such devices can be complex to manufacture. Also they may require disassembly and reassembly when a cartridge is to be replaced. This is a disadvantage if the user, as is common amongst those with diabetes, is infirm or has impaired vision.
