FN Thomson Reuters Web of Science™ VR 1.0 PT P PN US2007004968-A1 TI Cannula has lip seal movingly coupled to proximal section, to facilitate relative movement of instrument shaft between seal and proximal section and to maintain sealing engagement between shaft and proximal portion. AU BONADIO F VAUGH T AE BONADIO F (BONA-Individual) VAUGH T (VAUG-Individual) GA 2007122585 AB NOVELTY - The cannula (1) has an instrument insertion section (3) and a tube (2) with an access channel (7) for extension of an instrument. A lip seal (4) movingly couples to a proximal section to engage with an instrument shaft (5). The seal facilitates a lateral movement of the instrument, and maintains the sealing engagement between the seal and the instrument shaft. A coupling portion made of gelatinous elastomeric material with plasticizer consisting of naturally derived oils, synthetic oils and liquid oligomers, movingly couples the seal and the proximal section. USE - For medical device used as cannula to access inside abdomen, to introduce surgical instrument into abdomen of patient. ADVANTAGE - A certain degree of lateral movement of the instrument is enabled and facilitated, while maintaining the seal. The loss of insufflation gases from the abdomen is minimized. DESCRIPTION OF DRAWING(S) - The figure shows a partially cross-sectional, side view of the cannula and the instrument.
