Embodiment Construction

[0014] Embodiments described herein address the above needs and challenges by introducing an optoelectronic device with a biocompatible package to provide a hermetic seal for the electronic module of the optoelectronic device and its connections. Embodiments of the optoelectronic device have a number of different advantages, including the following.

[0015] (1) The embodiment can provide long-life environmental protection for the electronic module of the optoelectronic device and its electronic connectors. Embodiments are resistant to corrosion for at least 10 years, thereby enabling long-term use of the device implanted in the body.

[0016] (2) Embodiments are at least partially optically transmissive and thus well suited to accommodate electroactive IOLs.

[0017] (3) The embodiment is biocompatible and suitable for implantation in a patient.

[0018] (4) Embodiments have a sufficiently small form factor to enable implantation of these optoelectronic devices in the capsu...

Abstract

A bio-compatible package for an optoelectronic device is presented, to essentially eliminate moisture ingress and corrosion of the internal electronics of the device after it is implanted for in-vivouse. In some implementations, the optoelectronic device includes an optoelectronic assembly that includes an electronic module, an optoelectronic module, a power source, configured to energize the electronic module and the optoelectronic module, and an electronic interconnect to provide electronic couplings between the electronic module, the optoelectronic module, and the power source. The devicefurther includes a bio-compatible package, having a transparent front window and a transparent back window, the bio-compatible package configured to enable light to enter the optoelectronic device through the front window, propagate through the optoelectronic module, and leave the optoelectronic device through the back window, and to hermetically seal the optoelectronic assembly.

Description

technical field [0001] This patent document relates to electronic and optoelectronic devices. In more detail, this patent document relates to a partially transparent optoelectronic device comprising a hermetic biocompatible package for in vivo use. Background technique [0002] Pacemakers are by far the primary example of electronic devices in the body. The pacing leads are typically connected to the pacing device using socket and plug type connections. In these installations, non-corrosive metals, insulation and moisture barriers are used to maintain a life expectancy of up to 10 years. These connections are large and not airtight. As a result, unfavorable leakage currents may occur during device operation. These leakage currents are usually mitigated through the use of insulation and distance. Leakage current is also less important in pacemaker applications because the wires only carry current when the device is delivering pacing pulses. [0003] Recently, various el...
