METHODS AND DEVICES FOR PROVIDING ACCESS INTO A BODY CAVITY
First Claim
1. A method for providing access to a body cavity, comprising:
- positioning a retractor in tissue such that the retractor forms a pathway through the tissue and into a body cavity;
aligning a housing in a predetermined rotational orientation relative to the retractor to align a plurality of differing mating elements on the housing with a plurality of corresponding mating features on the retractor, the housing having a plurality of access ports configured to receive an instrument therethrough; and
advancing the plurality of differing mating elements into the plurality of corresponding mating features to mate the housing to the retractor.

Abstract
Methods and devices are provided for providing surgical access into a body cavity. In one embodiment, a surgical access device is provided that includes a housing coupled to a retractor. The housing can be have one or more sealing ports for receiving surgical instruments. Each sealing port can include one or more sealing elements therein for sealing the port and/or forming a seal around a surgical instrument disposed therethrough. Each sealing port can be in a fixed position relative to the housing and can be rotatable with the housing relative to the retractor. A plurality of safety shields can extend from the housing into the retractor to protect the retractor from instruments inserted through the sealing ports and into the retractor.

12. A method for providing access to a body cavity, comprising:
-
implanting a retractor having a working channel extending therethrough in tissue such that the retractor forms a pathway through the tissue and into a body cavity; and removably mating a housing having a plurality of sealing ports to the retractor such that a plurality of flexible shields each positioned adjacent to one of the sealing ports extend from the housing and into the working channel of the retractor. - View Dependent Claims (13, 14, 15, 16, 17)

18. A method for providing access to a body cavity, comprising:
-
positioning an alignment mechanism formed on a retractor positioned in tissue to form a pathway therethrough adjacent to an alignment mechanism formed on a housing having a plurality of sealing ports to position the housing in a predetermined rotational position relative to the retractor; engaging at least one mating mechanism formed on at least one of the housing and the retractor to releasably mate the housing and the retractor; and rotating the housing relative to the retractor to move the alignment mechanism formed on the housing a distance apart from the alignment mechanism formed on the retractor to thereby lock the housing to the retractor. - View Dependent Claims (19, 20)
