RETRIEVAL AND CENTERING DEVICE AND METHOD WITH PRESSURE AND ULTRASOUND FEATURES

摘要

The present invention relates generally to devices and methods for retrieving or manipulating objects within a lumen. More specifically, embodiments of the invention relate to devices and methods for retrieving or manipulating medical devices from a body lumen. One embodiment of the present invention provides a retrieval device having a retrieval snare and an ultrasound transducer to assist in the intravascular navigation of the device. The device enables a user to capture a foreign object located within the human anatomy, grasp said object in a controlled manner, and retrieve and remove said object from the human anatomy.

主权项

1. A system for retrieving an object from a lumen defined by a lumen wall, the system comprising:
a retrieval device comprising:
a sheath configured to fit within the lumen, the sheath having a proximal end and a distal end;a snare slidably disposed within the sheath, the snare having a shaft with a longitudinal axis, a proximal end and a distal end and a plurality of loop elements in connection with the distal end of the shaft; andan intravascular ultrasound transducer located on the distal end of the sheath or shaft;a user interface configured to receive input from an operator regarding a surgical procedure including an insertion site and a destination site; a display; a processor programmed to:
receive input from the user interface regarding the surgical procedure;determine anatomical landmarks between the insertion site and the destination site;receive an intravascular ultrasound signal from the intravascular ultrasound transducer;process the intravascular ultrasound signal into an image; andsend the image to the display.
