1. A system comprising:
- a sheath;
a vascular device configured to move relative to the sheath, and wherein at least one of the sheath and the vascular device comprises a movement sensor configured to sense relative movement of the vascular device and the sheath; and
a controller comprising a non-transient, tangible computer readable medium including logic, whereupon execution of the logic, the controller, based on relative movement sensed by the movement sensor;
(A) operates in an assisted mode wherein the controller is configured to regulate one or more operational parameters of the vascular device, the assisted mode including;
(A1) determining in a first instance a first position of the vascular device relative to the sheath and whether the first position is acceptable or unacceptable based on at least one predetermined threshold; and
(A2) in response to a determination in (A1), the controller controlling an operational parameter of the one or more operational parameters;
(B) operates in an unassisted mode wherein the controller is not configured to regulate the one or more operational parameters, the unassisted mode including;
(B1) determining in a second instance a second position of the vascular device relative to the sheath and whether the second position is acceptable based on the at least one predetermined threshold; and
;
(B2) in response to an unacceptable determination in (B1), the controller being unable to control the operational parameter.

Abstract
An endovascular device monitoring system is provided that determines, based on movement of the endovascular device past a selected reference location, at least one of a movement rate of a endovascular device and position of a distal end of a endovascular device in a body of a patient.

20. A system comprising:
-
a sheath; a vascular device configured to move relative to the sheath, and wherein at least one of the sheath and the vascular device comprises a movement sensor configured to sense relative movement of the vascular device and the sheath; and a controller comprising a non-transient, tangible computer readable medium including logic, whereupon execution of the logic, the controller, based on relative movement sensed by the movement sensor; (A) operates in an assisted mode wherein the controller is configured to regulate one or more operational parameters of the vascular device, the assisted mode including; (A1) determining in a first instance a first movement rate of the vascular device relative to the sheath and whether the first movement rate is acceptable or unacceptable based on at least one predetermined threshold; and (A2) in response to a determination in (A1), the controller controlling an operational parameter of the one or more operational parameters; (B) operates in an unassisted mode wherein the controller is not configured to regulate one or more operational parameters of the vascular device, the unassisted mode including; (B1) determining in a second instance a second movement rate of the vascular device relative to the sheath and whether the second movement rate is acceptable based on the at least one predetermined threshold; and
;(B2) in response to an unacceptable determination in (B1), the controller only monitoring the operational parameter without controlling the operational parameter.
