INTEGRATED IMAGING COMPONENT AND INTRAVASCULAR DEVICE DELIVERY SYSTEM

摘要

An apparatus and method for the intravascular placement of a filter includes an outer shaft with marker boards, an inner shaft, an intravascular ultrasound catheter with an ultrasonic imaging element, and the filter that is to be deployed. The ultrasound imaging element is enclosed within a proximal and distal transducer capsule configured to support the electronics of wiring of the element and provide for ease of insertion and withdrawal of the catheter. A guide wire is enclosed by and is moveable relative to the ultrasound catheter. In the stored position, the filter is secured adjacent to the distal inner shaft and proximal to the ultrasound catheter. When the apparatus is introduced into the vasculature, the ultrasound catheter provides real-time imaging of the vessel for identifying the appropriate location for placement of the filter. Once such a location has been identified, the filter is deployed and optionally, the ultrasonic imaging element used to confirm position, placement deployment of the filter.

主权项

1. An intravascular imaging capsule, comprising:
an imaging component mounted on a support frame with a proximal end and a distal end having a base adapted and configured to at least partially encircle a support tube, a proximal facing shoulder mount and a distal facing shoulder mount; a distal tip having a distal end and a proximal end and a lumen extending from the proximal end to the distal end wherein a proximal portion of the lumen is sized to fit over a portion of the distal facing shoulder mount and a distal portion of the lumen is sized to have an inner diameter of about the same size as an inner diameter of the support tube; and proximal cap having a distal end and a proximal end and a lumen extending from the proximal end to the distal end sized to be greater than the largest cross section dimension of the support tube wherein a distal portion of the lumen is sized to fit over a portion of the proximal facing shoulder mount.
