Abstract
Abstract There is provided an apparatus and a method of using the apparatus for creating a bleb of tissue of the pericardium of the heart, for accessing the pericardial space, intermediate the pericardium and the heart, and withdrawing fluid therefrom or delivering fluid, including drugs, therapeutic agents, or the like, thereto. The apparatus of the present invention includes a shaft with a first distal end and a second proximal end. A bore extends through the shaft from the distal end to the proximal end. The first end includes jaws, that open and close, as at least one of the jaws is movable. The second end includes a handle, at least a portion of the handle in communication with a mechanism in communication with the movable jaw, such that upon movement of at least a portion of the handle, the jaws can be opened and closed continuously. A needle, for puncturing the bleb of tissue grasped within the jaws, is movably mounted within the bore and is in communication with a mechanism for limiting its travel with respect to the bore.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
183 words
A pericardial access apparatus comprising: a shaft including a first end and a second end and having a longitudinal axis with a longitudinal bore passing therethrough; a first and second jaw at said first end of said shaft, said first and second jaws having a hinge therebetween providing for at least one of said first and second jaws to be moveable relative to the other jaw, said hinge including a pivot pin; each of said first and second jaws having a first and second grasping surface, respectively, said longitudinal axis of said shaft passing through said hinge between said first and second grasping surfaces of said jaws; a handle at said second end of said shaft, at least a portion of said handle in communication with at least one of said jaws such that movement of said handle causes movement of at least one of said jaws; a jaw activation rod in communication with said handle and at least one of said jaws for moving at least one of said jaws, and a hollow needle moveably mounted within said bore of said shaft.
Claim 2
Dependent Claim
183 words
A pericardial access apparatus comprising: a shaft including a first end and a second end and having a longitudinal axis with a longitudinal bore passing therethrough; a first and second jaw at said first end of said shaft, said first and second jaws having a hinge therebetween providing for at least one of said first and second jaws to be moveable relative to the other jaw, said hinge including a pivot pin; each of said first and second jaws having a first and second grasping surface, respectively, said longitudinal axis of said shaft passing through said hinge between said first and second grasping surfaces of said jaws; a handle at said second end of said shaft, at least a portion of said handle in communication with at least one of said jaws such that movement of said handle causes movement of at least one of said jaws; a jaw activation rod in communication with said handle and at least one of said jaws for moving at least one of said jaws, and a hollow needle moveably mounted within said bore of said shaft.
Claim 3
Dependent Claim
25 words
The pericardial access apparatus of claim 1, wherein said first and second jaws include a cavity therebetween when said jaws are in a closed position.
Claim 4
Dependent Claim
18 words
The pericardial access apparatus of claim 2, wherein said first and second jaws each include cooperatively configured teeth.
Claim 5
Dependent Claim

Claim 7
Dependent Claim
21 words
A pericardial access apparatus according to claim 1 wherein said needle has an arrangement for limiting needle travel within said bore.
Claim 8
Dependent Claim
59 words
The pericardial access apparatus of claim 6, wherein said bore includes a first portion proximate said first end and a second portion proximate said second end, said second portion of a greater diameter than said diameter of said first portion, and said arrangement for limiting needle travel is at least in part within said second portion of said bore.
Claim 9
Dependent Claim
17 words
The pericardial access apparatus of claim 1, wherein both of said first and second jaws are moveable.
