Claim 13:
14. A medical system, comprising:
a left atrial appendage closure device including an expandable framework and a proximal hub centered on a central longitudinal axis of the expandable framework;
wherein an insert is disposed within the proximal hub, the insert including a collar defining a circumferential wall of the insert configured to engage the proximal hub, a recess extending axially into the insert from a proximal end of the insert, and a post member disposed within the recess;
wherein the post member is radially spaced apart from the circumferential wall to define an annular gap between the post member and the circumferential wall, and the post member extends proximally from a distal end of the recess to a proximal surface of the post member;
wherein the insert includes a first connection structure disposed within the recess distal of the proximal surface of the post member;
wherein a pressure sensor is disposed within the post member and in communication with the proximal surface of the post member for sensing a fluid pressure proximal of the left atrial appendage closure device;
and
a delivery catheter having a second connection structure proximate a distal end of the delivery catheter, the second connection structure being configured to engage the first connection structure in a delivery configuration of the medical system;
wherein the insert includes a gap seal extending radially across the annular gap and covering a proximal end of the annular gap when the medical system is disposed in a released configuration in which the delivery catheter is disengaged from the left atrial appendage closure device;
wherein the distal end of the delivery catheter includes a hollow portion configured to extend over the post member and within the circumferential wall in the delivery configuration such that the distal end of the delivery catheter is disposed distal of the proximal end of the insert;
wherein the gap seal is fixedly attached to only one of the circumferential wall or the post member and extends across the proximal end of the annular gap to engage the other of the circumferential wall or the post member when the medical system is disposed in the released configuration.
