Recent Developments in Active Implants Innovation of interconnections for Active Implant Applications
Valtronic s Overview 1) Introduction of Valtronic: from Micro-technology to Medtech 2) Active Implants: application of miniaturized assembly technologies 3) From industry to Medtech: adaptation to specific constrains
30 Years in Micro Technology 1990 Electronic Module for Discovery Space Shuttle 1995 Chip for Formula One race 2000 World's smallest hearing aid 2006 World's smallest implantable pulse generator 2006 Retinal Implant for the Blind 2009 "Smart Pill" Wireless Motility Capsule
Smart Implants What Do We Mean By Smart? An implant that is able to provide in-vivo diagnostic biofeedback and/or treat a patient according to specific conditions Microsystem measuring and transmitting diagnostic data during or after implantation Needs to function in an autonomous way during the lifespan of a product which varies from six months to over fifty years
Monitoring Diabetics Acquires, processes and analyzes brain activity Implantable EEG Recorder Minimal Power Consumption no battery Tiny antenna and extreme miniaturization (COC, COB and 01005 SMD) Assembled in a RF transparent, bio-compatible material housing Measures 4mm thick x 17 mm diameter
Treating Glaucoma Allows ophthalmologists to observe the behavior of intraocular pressure continuously, particularly during while sleeping Built-in flexible electronics, silicone, ultrasonic flip-chip process and clean manufacturing
Preventing Heart Failure Stimulate/pace the heart through wireless transmission of energy Implantable leadless cardiac pacing device for treatment of heart rhythm management Six-layer flex board, 2mil lines and spaces, ENEPIG process.
Smart Implant Challenges Packaging / enclosure Reliable Processes & Technology Powering & Autonomy Detection & Sensing & Memory Interaction Communication
Design Constraint Trends in Stimulation Field More specific stimulation features: More electrodes & leads Innovative electrode design Channel modulation Device as minimally invasive as possible: Smaller Implant size Smaller and reliable interconnections
Application of micro-technology assembly to Active implant device Long term reliability of assembly Extreme miniaturization High computation power at low power
Miniaturization of micro-elecronics Wire-bonding with over molding Ultrasonic Flip-Chip
Miniaturization - Wire-Bonding with Over Molding Chip on Board 1.- Glue on substrate (FR4, Flex, G10 etc.) 2.- Die attach 3.- Wire bonding & testing Internal electronic of a cochlear implant Chip-on-board assembly with 0201 components Product lifetime 75 years!. 4.- Coating & testing
Miniaturization - Ultrasonic Flip Chip Bonding Assembly of flexible electronics in a silicone rubber lens Clean manufacturing 10x faster than glued flip-chip Lowest total cost of ownership Allows ophthalmologists to observe the behavior of intraocular pressure during sleep.
