1. A translumenal trocar device, comprising:
- a flexible elongate sleeve having an inner lumen extending between proximal and distal ends thereof and forming a working channel for receiving and guiding instruments to a surgical site;
a seal disposed within the inner lumen of the elongate sleeve such that instruments received in the working channel pass through the seal;
an anti-microbial agent effective to sterilize instruments passed through the lumen to maintain a sterile surgical site, the anti-microbial agent comprising at least one of a coating located on the seal and a material at least partially forming the seal; and
an enclosed reservoir coupled to the elongate sleeve and external to the inner lumen that is adapted to controllably deliver an anti-microbial solution to the elongate sleeve for transfer onto an instrument passed through the lumen.

Abstract
Devices are provided herein for translumenal access to a treatment site within a body cavity. In general, the devices include an elongate sleeve configured to provide access to a treatment site wherein various portions of the sleeve are associated with an anti-microbial agent. Additionally, the anti-microbial agent(s) can be disposed within a housing and/or inner lumen of the sleeve such that surgical instruments passing therethrough can be sterilized en route to and/or being withdrawn from the treatment site. Additionally, various methods are also provided herein for maintaining the sterility of a treatment site.

10. A method for maintaining a sterile surgical site, comprising:
-
positioning a flexible tube through a body lumen, the flexible tube defining a first inner lumen having a sponge disposed therein, and the flexible tube extending distally from a housing, the housing defining a second inner lumen having a seal contained therein; and inserting an instrument through the second inner lumen of the housing and subsequently through the first inner lumen of the flexible tube to position a distal end of the instrument adjacent to a treatment site, the instrument passing through the seal before passing and directly contacting the sponge, the seal forming a seal with the instrument passed therethrough, and the seal including an anti-microbial agent that sterilizes the instrument as it is passed through the flexible tube. - View Dependent Claims (11, 12, 13, 14)

15. A translumenal trocar device, comprising:
-
a housing having a first inner lumen extending therethrough; a flexible elongate sleeve extending distally from the housing and having a second inner lumen extending between proximal and distal ends thereof and being in communication with the first inner lumen, the first and second inner lumens forming a working channel for receiving and guiding instruments to a surgical site; a seal disposed within the second inner lumen of the elongate sleeve such that instruments received in the working channel pass through the seal; and a sponge disposed within the second inner lumen of the elongate sleeve such that instruments received in the working channel pass through and directly contact the sponge after passing through the seal, the sponge having an anti-microbial agent contained therein that is effective to sterilize instruments passed through the lumen to maintain a sterile surgical site.

16. A method for maintaining a sterile surgical site, comprising:
-
positioning a flexible tube through a body lumen, the flexible tube having a seal and a sponge disposed therein, and the flexible tube extending distally from a housing; and inserting an instrument through the flexible tube to position a distal end of the instrument adjacent to a treatment site, the seal having a proximal end and a distal end, the sponge having a proximal end and a distal end, and the distal end of the seal being spaced a distance away from the proximal end of the sponge such that the instrument passes through the seal before passing through the sponge, the sponge including an anti-microbial agent that sterilizes the instrument as it is passed through the flexible tube. - View Dependent Claims (17)
