Sensing delivery system for intraluminal medical devices
First Claim
1. A delivery system for implanting an intraluminal medical device within a body vessel, said delivery system comprising:
- an elongate tubular member having a first distal end adapted for insertion into a body vessel;
a dilator disposed in the tubular member and having a second distal end adapted for insertion into a body vessel, the dilator cooperating with the tubular member to define a device chamber between the tubular member and the dilator;
an intraluminal medical device disposed in the device chamber; and
a sensing apparatus adapted to determine at least one of a vessel parameter and a fluid parameter and to transmit information relating to the at least one of a vessel parameter and a fluid parameter to a signal-receiving apparatus.

Abstract
Delivery systems and methods of treatment are described. The delivery systems facilitate visualization, monitoring, or sensing of body vessel parameters, blood parameters, or an intraluminal medical device included in the delivery system prior to, during, or after deployment in a body vessel. A sensing apparatus associated with the delivery systems provide information relating to the body vessel and/or fluid within the body vessel that can be used for verification of placement, confirmation of intraluminal medical device function, and/or determination of the need for additional delivery steps, among other purposes. The information can also be used for verification of initial vessel sizing information.

13. A method of implanting an intraluminal medical device in a body vessel of a patient, the method comprising the steps of:
-
providing a delivery system, the delivery system including an intraluminal medical device and a sensing apparatus adapted to determine at least one of a vessel parameter and a fluid parameter;
inserting a distal end of the delivery system into said body vessel of a patient;
determining at least one of a vessel parameter and a fluid parameter using the sensing apparatus;
deploying the intraluminal medical device; and
removing the delivery system from said body vessel of the patient. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A method of implanting an intraluminal valve medical device in a body vessel of a patient, the method comprising the steps of:
-
determining initial size information relating to said vessel at a point of treatment;
selecting an intraluminal valve medical device having a device size based on the initial size information;
providing a delivery system comprising the intraluminal valve medical device and a sensing apparatus adapted to determine secondary size information relating to said vessel at the point of treatment;
inserting a distal end of the delivery system into the body vessel of a patient;
advancing the distal end of the delivery system to the point of treatment in the body vessel;
determining secondary size information relating to said vessel at a point of treatment;
confirming the device size by comparing the secondary size information to the initial size information;
deploying the intraluminal medical device; and
removing the delivery system from the body vessel of the patient.
