Abstract:
1. An apparatus for closing an aperture through a wall of a structure within a patient's circulatory system, comprising: a solid central structure having an outer perimeter and a longitudinal axis; a first portion operatively coupled to the central structure within the outer perimeter and transitionable between a collapsed condition and an expanded condition, the first portion being formed from a first web of interwoven wire strands, the first web extending radially outward from the longitudinal axis by a greater amount in the expanded condition than in the collapsed condition, and being configured to conform to an inner surface of tissue around the aperture when in the expanded condition; and a second portion operatively coupled to the central structure within the outer perimeter and transitionable between a collapsed condition and an expanded condition, the second portion being formed from a second web of interwoven wire strands, the second web extending radially outward from the longitudinal axis by a greater amount in the expanded condition than in the collapsed condition, and being configured to conform to an outer surface of tissue around the aperture when in the expanded condition, wherein the first portion is operatively coupled to the second portion within the outer perimeter of the central structure and the apparatus has a longer length when the first portion and the second portion are in the collapsed condition than when the first portion and the second portion are in the expanded condition.
