Abstract:
1. An access port comprising: a longitudinally extending shaft defining a longitudinal axis surrounding a central working passage; and at least one material capable of changing its configuration between a first condition and a second condition to form at least one anchoring member having a distal end circumferentially disposed about the longitudinal axis in the second condition such that the distal end of the at least one anchoring member forms a monolithic ring encircling a continuous path about the entire circumference of an outer diameter of the shaft, the ring being spaced apart from the shaft by a circumferential trough formed in the at least one anchoring member, the at least one material extending from a distal end of the shaft in both the first and second conditions, wherein a portion of the at least one anchoring member is disposed in angular relation relative to the longitudinal axis, and wherein the material is selected from the group consisting of shape memory polymers, shape memory metals, shape memory alloys, electroactive polymers, and combinations thereof.
