Abstract

A method is provided for measuring an opening of an appendage of an atrium of a subject, the method including inserting a catheter into the atrium of the subject. At least one loop is deployed from a wall of the catheter, such that a distal end of the loop is distal to a distal end of the catheter. The loop is used to measure the opening of the appendage.

Claims

1. A method for measuring an opening of an appendage of an atrium of a subject, the method comprising:

inserting a catheter into the atrium of the subject;

thereafter, deploying at least one loop from a wall of the catheter, such that a distal end of the loop is distal to a distal end of the catheter; and

thereafter, using the loop to measure the opening of the appendage,

wherein the loop includes a longitudinal member that passes through a first opening and a second opening in the catheter wall, and

wherein deploying the loop comprises deploying the loop by passing the longitudinal member through at least one of the first and second openings.

6. The method according to claim 1, wherein inserting the catheter into the atrium comprises inserting the catheter into the atrium using a transvenous approach.

7. The method according to claim 1, further comprising:

in response to the measuring, selecting an implant of an appropriate size;

delivering the implant to the opening, by passing the implant through the catheter; and

implanting the implant in the opening.

2. A method for measuring an opening of an appendage of an atrium of a subject, the method comprising:

inserting a catheter into the atrium of the subject;

thereafter, deploying at least two loops from a wall of the catheter, such that respective distal ends of the at least two loops are distal to a distal end of the catheter; and

thereafter, using the at least two loops to measure the opening of the appendage.

3. The method according to claim 2, wherein deploying the at least two loops comprises deploying more than two loops.

4. The method according to claim 2, wherein inserting the catheter into the atrium comprises inserting the catheter into the atrium using a transvenous approach.

5. The method according to claim 2, further comprising:

in response to the measuring, selecting an implant of an appropriate size;

delivering the implant to the opening, by passing the implant through the catheter; and

implanting the implant in the opening.
