Abstract
An occlusion device includes a body having a plurality of layers and defining a first diameter. Each layer of the plurality of layers is releasably coupled to a respective inwardly-adjacent layer. An outermost layer of the plurality of layers is removable from the respective inwardly-adjacent layer. Removal of the outermost layer reduces an outer diameter of the body from the first diameter to a second diameter that is less than the first diameter.
Claims19
An occlusion device, comprising:
- a body including a plurality of layers and defining a first diameter, each layer of the plurality of layers releasably coupled to a respective inwardly-adjacent layer,
- wherein an outermost layer of the plurality of layers is removable from the respective inwardly-adjacent layer, and wherein removal of the outermost layer reduces an outer diameter of the body from the first diameter to a second diameter that is less than the first diameter.
The occlusion device according to claim 6, wherein the compressible material is a closed-cell foam.
A uterine manipulator, comprising:
- a handle;
- a shaft extending distally from the handle;
- an end effector assembly disposed at a distal end portion of the shaft;
- an occlusion device supported on the shaft, including:
- a body including a plurality of layers and defining a first diameter, each layer of the plurality of layers releasably coupled to a respective inwardly-adjacent layer,
- wherein an outermost layer of the plurality of layers is removable from the respective inwardly-adjacent layer, and wherein removal of the outermost layer reduces an outer diameter of the body from the first diameter to a second diameter that is less than the first diameter.
A method for performing a surgical procedure, comprising:
- determining the size of a body cavity;
- providing an occlusion device having a plurality of layers and defining a first diameter;
- applying a tensile force to a first outermost layer of the plurality of layers to remove the first outermost layer from the occlusion device such that an outer diameter of the occlusion device is reduced from the first diameter to a second diameter less than the first diameter;
- and
- positioning the occlusion device within the body cavity and forming a seal therein.
