Apparatus and method for targeting a body tissue
First Claim
1. An apparatus for targeting a desired target site on a body tissue that separates a first body cavity from a second body cavity of a patient, the apparatus comprising:
- a catheter having a longitudinally extending catheter lumen and adapted to provide access to the first body cavity;
a framing member having a collapsed condition in which the framing member is adapted for insertion into the first body cavity through the catheter lumen and an expanded condition in which the framing member is adapted for placement within the first body cavity, the framing member having a framing member body;
at least one target point carried by the framing member and adapted for placement adjacent the desired target site; and
at least one target wire attached to at least one target point, at least a portion of the target wire extending through the catheter lumen, and the target wire being substantially spaced apart from the framing member body.

Abstract
An apparatus for targeting a desired target site on a body tissue that separates a first body cavity from a second body cavity of a patient includes a catheter having a longitudinally extending catheter lumen and adapted to provide access to the first body cavity. A framing member has a collapsed condition in which the framing member is adapted for insertion into the first body cavity through the catheter lumen and an expanded condition in which the framing member is adapted for placement within the first body cavity. The framing member has a framing member body. At least one target point is carried by the framing member and is adapted for placement adjacent the desired target site. At least one target wire is attached to at least one target point. At least a portion of the target wire extends through the catheter lumen. The target wire is substantially spaced apart from the framing member body. A method of using the apparatus is also described.

11. A method for puncturing a body tissue of a patient at a desired target site, the method comprising the steps of:
-
inserting a catheter having a longitudinally extending catheter lumen into the patient; advancing the catheter into a first body cavity of the patient; providing a framing member having a framing member body and carrying at least one target point, the target point adapted for placement adjacent the body tissue to indicate the desired target site; providing at least one target wire attached to at least one target point, at least a portion of the target wire extending through the catheter lumen, and the target wire being substantially spaced apart from the framing member body; inserting the framing member in a collapsed condition into the first body cavity through the catheter lumen; expanding the framing member into an expanded condition within the first body cavity; positioning the target point adjacent the desired target site; inserting a puncture needle into the first body cavity through the catheter lumen; connecting the puncture needle to the target wire; guiding the puncture needle to the target point with the target wire; and puncturing the body tissue with the puncture needle at the desired target site. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 25)
