Radially expandable access system including trocar seal
First Claim
1. A radially expandable sleeve component, for use with an access system, the sleeve component comprising:
- a handle having a passage therethrough; and
a sleeve body having a proximal end connected to the handle, a distal end, and an axial lumen aligned with the passage of the handle, the sleeve body having a length, the sleeve body being constructed from a radially expandable braid, wherein the braid is formed of a mesh of non-elastic filaments which axially shortens the length of the sleeve body as the sleeve body is radially expanded, wherein the distal end of the sleeve body is flared radially outward.

Abstract
The present disclosure relates to access systems which may be percutaneously or otherwise introduced while in a narrow diameter configuration and, which after introduction, may be radially expanded to accommodate passage of larger diameter surgical instruments therethrough. According to an aspect of the present disclosure, a radially expandable sleeve component, for use with an access system, is provided. The sleeve component includes a handle having a passage therethrough; and a sleeve body having a proximal end connected to the handle, a distal end, and an axial lumen aligned with the passage of the handle, the sleeve body having a length. The sleeve body is constructed from a radially expandable braid, wherein the braid is formed of a mesh of non-elastic filaments which axially shortens the length of the sleeve body as the sleeve body is radially expanded. The distal end of the sleeve body is flared radially outward.

5. An access system, comprising:
-
a radially expandable sleeve component, including;
a handle having a passage therethrough; and
a sleeve body having a proximal end connected to the handle, a distal end, and an axial lumen aligned with the passage of the handle, the sleeve body having a length, wherein the distal end of the sleeve body is flared radially outward; and
a cannula tube having a proximal end, a distal end, and a lumen extending therethrough, the cannula tube being sized to be received in the aperture of the handle of the radially expandable sleeve component, the cannula tube having a length which is shorter than the length of the sleeve body when the cannula tube is fully inserted into the sleeve body of the radially expandable sleeve component. - View Dependent Claims (6, 7, 8, 9, 10)

11. An access system, comprising:
-
a radially expandable sleeve component, including;
a handle having a passage therethrough; and
a sleeve body having a proximal end connected to the handle, a distal end, and an axial lumen aligned with the passage of the handle, the sleeve body having a length, wherein the distal end of the sleeve body tapers radially inward; and
a cannula tube having a proximal end, a distal end, and a lumen extending therethrough, the cannula tube being sized to be received in the aperture of the handle of the radially expandable sleeve component, the cannula tube having a length which is shorter than the length of the sleeve body when the cannula tube is fully inserted into the sleeve body of the radially expandable sleeve component so that the tapered distal end of the sleeve body engages an instrument inserted into the radially expandable sleeve component. - View Dependent Claims (12, 13, 14, 15, 16, 17)
