Claims
- 1. 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.
- 2. 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.
- 3. The pericardial access apparatus of claim 2, wherein said first and second jaws each include cooperatively configured teeth.
- 4. The pericardial access apparatus of claim 3, wherein said teeth are of the same pitch.
- 5. The apparatus of claim 4, wherein said teeth are of different pitches.
- 6. A pericardial access apparatus according to claim 1 wherein said needle has an arrangement for limiting needle travel within said bore.
- 7. 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.
- 8. The pericardial access apparatus of claim 1, wherein both of said first and second jaws are moveable.
- 9. The pericardial access apparatus of claim 7, wherein said handle includes a second arm, fixedly attached to said shaft.
- 10. A pericardial access apparatus according to claim 1 wherein said jaw activation rod acts directly at said hinge between said first and second jaws to cause movement of said jaws.
