Abstract
Devices and methods are disclosed herein for a closure device. A closure device includes a body movable from a pre-deployed configuration towards a deployed configuration, a plurality of tissue-engaging portions extending from the body. At least two of the tissue-engaging portions are separated by a first distance in the deployed configuration and a second distance in the pre-deployed configuration in which the first distance is smaller than the second distance. The closure device also includes a plurality of device capture features secured to the body. The device capture features are configured to move the tissue-engaging portions to a separation greater than the first distance.
Claims17
A closure device, comprising:
- a body configured to move between a pre-deployed configuration and a deployed configuration;
- and
- a plurality of tissue-engaging portions extending from the body, at least two of the tissue-engaging portions being separated by a first distance in the deployed configuration and a second distance in the pre-deployed configuration, wherein the first distance is smaller than the second distance, wherein in at least the deployed configuration, the body forms an inner periphery and an outer periphery, at least a portion of the inner periphery defining a first plane, and wherein at least a portion of the body extends away the first plane between the inner periphery and the outer periphery.
A closure device, comprising:
- a body being configured to move relative to a central axis between a pre-deployed configuration and a deployed configuration, wherein a first transverse axis is disposed orthogonally to the central axis and a second transverse axis is disposed orthogonally to the central axis and the first transverse axis;
- and
- a plurality of tissue-engaging portions extending from the body, at least two of the tissue-engaging portions being separated by a first distance in the deployed configuration and a second distance in the pre-deployed configuration, wherein the first distance is smaller than the second distance, wherein the body is curved relative to at least one of the first transverse axis and the second transverse axis while in at least one of the pre-deployed configuration and the deployed configuration.
A method, comprising:
- placing a closure device into proximity with a tissue surface having a puncture defined therein in a pre-deployed configuration;
- and
- moving the closure device to a deployed configuration, wherein the closure device includes a curved interior surface in contact with the tissue surface.
