The turbine engine assembly has a frame and a turbine engine spool. A first body and a second body, each having a wedge shaped outer appearance, where a dimension in the depth direction gradually becomes thinner from one side to the other side in the width direction, are slidably coupled via a slide mechanism to constitute a body. The molding material includes a first portion overlapping the second package component, wherein the first portion includes a first top surface, and a second portion encircling the first portion and molding bottom portions of the plurality of electrical connectors therein. A first filter is selective for transmitting the first wavelength band and not transmitting the second wavelength band. In one implementation, the embolic obstruction retrieval device is delivered to the embolic obstruction through the lumen of a delivery catheter.
