Abstract
A surgical access system includes a tubular member defining a longitudinal axis and having an axial lumen. The tubular member includes a braided material adapted to expand from a first initial condition having a first cross-sectional dimension to a second expanded condition having a second-cross sectional dimension greater than the first cross-sectional dimension. The tubular member defines an oblique end surface. An access housing is mounted to the tubular member. The access housing is dimensioned for engagement by the user. A process for manufacturing a surgical access device is also disclosed.
Claims12
A process for manufacturing a surgical access device, comprising:
- providing a tubular member defining a longitudinal axis and having an axial lumen, the tubular member adapted to expand from a first initial condition having a first cross-sectional dimension to a second expanded condition having a second-cross sectional dimension greater than the first cross-sectional dimension;
- creating a flared end portion of the tubular member;
- mounting a mounting element to the flared end portion of the tubular member by positioning the mounting element onto a mandrel, advancing the tubular member onto the mandrel, and folding the flared end portion of the tubular member over the mounting element such that the flared end portion engages the mounting element;
- and
- securing the mounting element to a housing by positioning the mounting element between a hub and a base of the housing such that the tubular member is captured between more than two surfaces of the housing.
