First Claim
Patent Images
1. A device for forming a tract in tissue comprising:
- a housing comprising at least one groove; and
at least one tissue-piercing member coupled to the housing and comprising a distal end having a tissue-piercing tip,wherein the at least one tissue-piercing member is movable relative to the housing along a path predetermined by the configuration of the at least one groove.

Abstract
Described here are devices, methods, and kits for forming one or more tracts in tissue. The tracts may be formed in any suitable or desirable tissue, and may seal relatively quickly without the need for a supplemental closure device. In some variations, the methods may comprise advancing a tissue-piercing member along a predetermined path of a tract-forming device to form one or more tracts in tissue (e.g., a vessel wall). The tract or tracts may, for example, provide access for one or more tools.
