Abstract
The present disclosure describes a device that can be implanted into the left atrial appendage for occlusion. The device can prevent or reduce thrombus formation in this anatomic region for patients with atrial fibrillation. This device includes a patient-specific inflatable device that represents a patient's anatomy or morphological class. The inflatable device can be designed by imaging (e.g., computed tomography, magnetic resonance imaging) the patient's anatomy. Through a catheter (or surgically), the inflatable device can be filled with an inflation fluid to occlude the appendage in a patient-specific fashion.
Claims20
A method comprising:
- determining, based on a non-invasive medical image of an anatomy of a patient, a morphology class of an atrial appendage of the patient;
- selecting, based on the morphology class, a shape template from among a set of predetermined shape templates;
- obtaining an inflatable implant manufactured according to the selected shape template, the inflatable implant configured to have, in an inflated state, a volumetric shape corresponding to the shape template;
- and
- occluding the atrial appendage of the patient using the class specific inflatable implant with the volumetric shape.
