1. An insertion device, comprising:
- a cannula having a proximal end, a distal end, and a lumen extending therebetween, the lumen configured to allow for passage of a surgical device to a treatment site; and
a housing having a proximal end and a distal end located proximal to the proximal end of the cannula, wherein the distal end of the housing is movably coupled to the proximal end of the cannula by a flexible member, the housing having a lumen therethrough in alignment with the lumen in the cannula.

Abstract
An insertion device configured for providing access to a treatment site within a body cavity is provided herein. In general, the device includes an elongate cannula configured to receive and allow passage therethrough of a surgical instrument to a treatment site. Additionally, a proximal end of the cannula is movably coupled to a housing thereby facilitating delivery of the instrument therethrough. Additionally, various embodiments of a method for delivering (e.g., laprascopically, endoscopically, etc.) various surgical instruments to various treatment sites via an elongate cannula wherein the cannula includes a proximal end movably coupled to a housing are provided herein.

15. A method for delivering a surgical instrument to a treatment site, comprising:
-
inserting a cannula through tissue such that the cannula provides a working channel extending to a treatment site; inserting an instrument through the cannula; positioning the instrument offset from an axis of the cannula such that a housing having a distal end located proximal to the proximal end of the cannula and movably coupled to the proximal end of the cannula pivots relative to the cannula so as to move with the instrument. - View Dependent Claims (16, 17, 18)
