Medical tool for access to internal tissue

摘要

A medical tool for minimally invasive access to the pericardium or similar internal tissue. The medical tool includes a shaft with jaws disposed on a distal end of the shaft and a mechanism for opening and closing the jaws connected to the proximal end of the shaft. The jaws include needle-like elements that extend from the jaws. A delivery element defining a delivery lumen extends along the tool, parallel and adjacent to the shaft, with a distal end of the delivery element being positioned between the jaws. Moreover, the distal ends of each of the jaws define a semi-circular shape such that when the first and second jaws are closed, a hole through the closed jaws is formed by the semi-circular shapes.
