Abstract: A trocar assembly includes a trocar valve body defining a cavity. The assembly includes a rotatable valve handle that is elongated and has a first end and a second end. The first end is sized and configured to be rotatably maintained within the cavity and the second end extends outwardly so as to be actuatable by a user. The rotatable valve handle defines a lumen therethrough which extends longitudinally from the first end to the second end. The valve body defines an outlet that communicates with the cavity. The rotatable valve handle is rotatable from an open position, in which the lumen is at least partially aligned with the outlet so as permit fluid to pass through the lumen, and a closed position, in which the lumen is not aligned with the outlet so as prevent fluid to pass through the lumen.

Abstract: A surgical access apparatus for use during a surgical procedure for passing through tissue to an underlying surgical area is provided. The surgical access apparatus includes a vibration source connected to a seal member located in an internal passage of an access member. The seal is configured to form a substantial sealing relation with an inserted surgical instrument and substantially close in the absence of the surgical instrument. The vibration source causes the seal to vibrate, in order to decrease the force needed to insert the surgical instrument. The source of vibration may be one of the following: a rotating eccentric mass, mass moving in a linear path, exciting a piezoelectric, a crystal, or an electro active polymer capable of expanding or contracting.
