Abstract
device for increasing a cross-sectional area of a body lumen, comprising a scaffolding with opposing tissue-engaging portions and at least one expansion member having a thickness, the scaffolding being configured to transition between a compressed configuration having a reduced distance between the first and second tissue-engaging portions and a deployed configuration having an increased distance between the tissue-engaging portions, the first tissue- engaging portion of the at least one expansion member being secured to a shaft at a first end of the shaft configured in a telescoping arrangement with a housing, the shaft having a longitudinal axis and being positioned coaxially within the housing, the shaft further having a driving element secured to a second end of the shaft for biasing the shaft outwards from the housing along the longitudinal axis of the shaft, each of the tissue-engaging portions having increased surface areas in a direction perpendicular to the longitudinal axis of the shaft, and relative to the thickness of the expansion member.
Claims (10)
1. A device for increasing a cross-sectional area of a body lumen, comprising a scaffolding with opposing tissue-engaging portions and at least one expansion member having a thickness, the scaffolding being configured to transition between a compressed configuration having a reduced distance between the first and second tissue-engaging portions and a deployed configuration having an increased distance between the tissue-engaging portions, the first tissue- engaging portion of the at least one expansion member being secured to a shaft at a first end of the shaft configured in a telescoping arrangement with a housing, the shaft having a longitudinal axis and being positioned coaxially within the housing, the shaft further having a driving element secured to a second end of the shaft for biasing the shaft outwards from the housing along the longitudinal axis of the shaft, each of the tissue-engaging portions having increased surface areas in a direction perpendicular to the longitudinal axis of the shaft, and relative to the thickness of the expansion member.
2. The device of claim 1, wherein the tissue-engaging portions comprise a lateral plate.
3. The device of claim 2, wherein the tissue-engaging portions further comprise an anchor.
4. The device of claim 1, wherein the at least one expansion member is a bi- directional expansion member and wherein the tissue-engaging portions are secured to opposing ends of the bi-directional expansion member.
5. The device of claim 1, wherein a pair of uni-directional expansion members are coupled in opposing directions and wherein each tissue-engaging portion is secured to one end of each uni-directional expansion member.
6. The device of claim 6, wherein the pair of uni-directional expansion members are coupled by a pivot, wherein the pivot is biased to align the uni-directional expansion members longitudinally but allows the uni-directional expansion members to deflect with respect to each other.
7. The device of claim 6, further comprising a tether secured to the pivot.
8. The device of claim 1, wherein at least a portion of the scaffolding is coated with an agent.
9. The device of claim 8, wherein the agent comprises an anti-encrustation agent.
10. The device of claim 1, further comprising an agent disposed within at least one reservoir formed in the scaffolding.
