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.
Claims23
A closure device, comprising:
- 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 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;
- and
- a plurality of device-capture features secured to the body, the device-capture features being configured to move the tissue-engaging portions to a separation greater than the first distance.
A method, comprising:
- deploying a closure element having tissue-engaging portions and device-capture features, the tissue-engaging portions engaging tissue adjacent a tissue opening to substantially close the opening;
- engaging device-capture features with a distal end of a medical device;
- and
- moving the device-capture features to withdraw the tissue-engaging portions from engagement with the tissue adjacent the tissue opening.
A method, comprising:
- deploying a closure element to tissue adjacent a tissue opening to substantially close the opening following a first procedure, the closure element including a body having a plurality of expandable elements, the expandable elements being configured to move resiliently between a pre-deployed configuration and a deployed configuration, 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, and a plurality of device capture elements operatively associated with the expandable elements;
- locating the deployed closure element;
- engaging the device-capture features;
- and
- moving the device-capture features to withdraw the tissue-engaging portions from engagement with the tissue adjacent the tissue opening.
