METHODS AND DEVICES FOR PROVIDING ACCESS THROUGH TISSUE TO A SURGICAL SITE
First Claim
1. An adjustable access device, comprising:
- a housing having a cannula extending distally therefrom, the housing and the cannula defining a working channel extending therethrough for receiving an instrument; and
an actuator on the housing configured to cut the cannula to adjust a length of the cannula.

Abstract
Methods and devices are provided for providing access through tissue to a surgical site. Generally, the methods and devices allow adjustment of a surgical access port'"'"'s longitudinal length. In one embodiment, a surgical access port is provided that includes a housing having a cannula distally extending therefrom. The housing can be configured to cut a proximal portion of the cannula to adjust a longitudinal length of the cannula and hence of the surgical access port. In another embodiment, a surgical access port is provided that includes a cannula formed of a plurality of modular segments removably coupled together. One or more of the segments can be configured to be removable from the cannula to change the cannula'"'"'s longitudinal length.

10. A method of adjusting an access device, comprising:
-
positioning a cannula through an opening in tissue such that a distal end of the cannula is positioned in a body cavity underlying the tissue and such that a housing coupled to a proximal end of the cannula is positioned outside the tissue; proximally moving the cannula relative to the housing; and adjusting a length of the cannula by actuating the housing to cut the cannula. - View Dependent Claims (11, 12, 13, 14, 15)

16. A method of adjusting an access device, comprising:
-
inserting a cannula having a first longitudinal length through an opening in tissue such that a housing at a proximal end of the cannula is positioned above the tissue and such that a distal end of the cannula is positioned in a body cavity underlying the tissue; and moving the cannula in a proximal direction relative to the housing such that the cannula moves from the first longitudinal length to a second longitudinal length that is less than the first longitudinal length. - View Dependent Claims (17, 18, 19, 20)
