Claims21
A medical device, comprising:
- an elongated tool having at least one actuator, at least a portion of the at least one actuator proximate a distal end of the elongated tool and receivable through an opening in tissue from a first side of the tissue to a second side of the tissue, the at least one actuator operable from a proximate end of the elongated tool to embed a plurality of tissue piercing tips of a clip from the second side of the tissue to seal the opening in the tissue, each of the plurality of tissue piercing tips of the clip protected after the plurality of tissue piercing tips have been expanded to encompass the opening in the tissue, and the tissue piercing tips unprotected as part of embedding the tissue piercing tips in the tissue.
A medical device, comprising:
- an elongated tool having a proximate end and a distal end, at least the distal end receivable internally in a body;
- and
- at least one actuator having at least one arm located at least proximate the distal end of the elongated tool, which at least one arm protectively retains a respective one of each of a plurality of tissue piercing tips of a clip, used to close a hole in the tissue, until the tissue piercing tips start to pierce the tissue at locations encompassing the hole in the tissue.
