Patent Images
1. A modular 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;
at least one seal element disposed within the working channel and configured to form at least one of a seal around an instrument disposed through the working channel and a seal across the working channel when no instrument is disposed therethrough; and
an anchor segment removably coupled to a distal end of the cannula.

Abstract
Methods and devices are provided for providing surgical access into a body cavity. A surgical access port is provided that has an adjustable longitudinal length, such as by being formed from multiple segments configured to move relative to one another. An anchor can be coupled to a distal end of the surgical access port to help secure the surgical access port within a tissue opening by engaging a distal side of the tissue. Optionally, the anchor can be removably coupled to the distal end of the surgical access port, thereby allowing any one of a plurality of anchors to be selectively coupled thereto.
