DEVICES, METHODS AND KITS FOR FORMING TRACTS IN TISSUE
First Claim
1. A system for forming a tract in a targeted tissue structure wall located across a thickness of tissue from a point of patient access, comprising:
- a. a tissue-piercing member comprising a proximal elongated portion and a distal elongated portion coupled to the proximal elongated portion, the distal portion comprising a tissue-piercing tip; and
b. a mandrel;
wherein a lumen is formed through both portions of the tissue-piercing member and configured to slidably receive the mandrel, such that when the mandrel is received by both elongated portions, the elongated portions assume a first orientation relative to each other, and when the mandrel is withdrawn proximally out of at least the distal elongated portion, the elongated portions assume a second orientation relative to each other.

Abstract
Described here are methods, devices and kits for locating tissue and/or forming one or more tracts in tissue. In some variations, tissue may be located (e.g., using one or more optical sensors, ultrasound sensors, thermal sensors, or the like) and one or more tracts may be formed through the tissue after it has been located. In certain variations, the same device may be used both to locate tissue and to form one or more tracts in the tissue. In some variations, a tissue-piercing member for forming one or more tracts in tissue may comprise a first elongated portion and a second elongated portion, and an angle therebetween.
