Abstract
Medical devices and methods for deploying tissue anchors for simple and reliable closure of openings in tissue are disclosed. The medical device generally includes an access sheath and a flexible puncturing device. The flexible puncturing device is sized to be slidably received by the access sheath. The flexible puncturing device has a lumen sized to receive the tissue fastener. The flexible puncturing device is operable between a first linear configuration and a second non-linear configuration. A distal end of the flexible puncturing device is laterally spaced from the access sheath in the second non-linear configuration, and preferably retroflexes to provide placement of the tissue anchors on a proximal side of the tissue.
Claims20
A medical device for placing a tissue fastener through tissue, the medical device comprising:
- an access sheath defining an access lumen;
- and
- a flexible puncturing device sized to be slidably received by the access lumen of the access sheath, the flexible puncturing device defining a lumen sized to receive the tissue fastener, the flexible puncturing device operable between a first linear configuration and a second non-linear configuration, a distal end of the flexible puncturing device being laterally spaced from the access sheath in the second non-linear configuration and facing generally proximally to pierce the tissue from a distal side to a proximal side of the tissue.
A method for placing tissue fasteners through tissue to close an opening in the tissue, the method comprising the steps of:
- positioning an access sheath proximate the tissue, the access sheath defining a lumen;
- advancing a flexible puncturing device through the access lumen of the access sheath,
- retroflexing the flexible puncturing device such that a distal end of the flexible puncturing device faces proximally;
- passing a distal end of the flexible puncturing device through the tissue from a distal side to a proximal side of the tissue;
- and
- delivering a first tissue fastener from the flexible puncturing device to the proximal side of the tissue.
