Medical tool for access to internal tissue
First Claim
1. A medical tool comprising:
- a shaft defining a proximal end and a distal end;
first and second jaws disposed on the distal end of the shaft;
a first needle-like element protruding from the first jaw;
a second needle-like element protruding from the second jaw;
a delivery element defining a delivery lumen and positioned parallel and adjacent to the shaft with a distal end of the delivery element being disposed between the first and second jaws; and
a mechanism coupled to the proximal end of the shaft and mechanically coupled to the first and second jaws to open and close the first and second jaws.

Abstract
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.

18. A pericardial access tool comprising:
-
a shaft defining a proximal end and a distal end;
first and second jaws disposed on the distal end of the shaft;
first and second needlelike elements protruding respectively from the first and second jaws for puncturing a pericardium so that the first and second jaws can grasp the pericardium;
a delivery means positioned parallel and adjacent to the shaft with a distal end of the delivery means being disposed between the first and second jaws for insertion into the pericardium when the pericardium is grasped by the first and second jaws; and
a mechanism coupled to the proximal end of the shaft and mechanically coupled to the first and second jaws to open and close the first and second jaws to grasp the pericardium. - View Dependent Claims (19, 20)
