What skills do you need for product development?
In my experience getting prototypes made early to obtain feedback from users helps a lot. I utilize 3D printing where I can to build a representative design so users can follow as I explain its operational features and overall benefits. The idea is to fail early and fail fast. Get that prototype out to users as soon as possible and iterate product design in real time based on feedback.

Novel Artificial Urinary Sphincter for Stress Urinary Incontinence Treatment
ProQuest Dissertation
The American Medical System’s AMS 800™ has been the gold standard for over 40 years with over 150,000 patients treated for Urinary Incontinence and is the leading treatment for male stress urinary incontinence (SUI) following prostate surgery. Type III SUI, or intrinsic sphincter deficiency, is the inability of the urethra to maintain closure pressure sufficient to keep the patient clinically dry at rest and during periods of heightened activity (~120 cmH2O; coughs, sneezes, posture changes…
The American Medical System’s AMS 800™ has been the gold standard for over 40 years with over 150,000 patients treated for Urinary Incontinence and is the leading treatment for male stress urinary incontinence (SUI) following prostate surgery. Type III SUI, or intrinsic sphincter deficiency, is the inability of the urethra to maintain closure pressure sufficient to keep the patient clinically dry at rest and during periods of heightened activity (~120 cmH2O; coughs, sneezes, posture changes, and exercises). The current AMS 800™ is not personalized to a patient’s needs and compromises with an in between pressure- as high (61–70 cmH2O) as it can be without exceeding safety threshold levels. As such many men still leak when they are active. The market is hungry for a device that can adapt to the patient’s level of activity, reducing pressure most of the day to protect the urethra and then briefly increasing the pressure when he is more active.
We are developing a novel implantable pump (henceforth called “add-on device”) which will be an add-on to the AMS 800™ and it includes a solenoid coil-cum-plunger and a fluid reservoir within the pump body. The add-on device will be small, light-weight and battery powered, and maintain compatibility with the AMS 800™ device. The device idea is in its proof-of-concept stage. This add-on device can be a possible solution to reducing the risks including urethral atrophy (leading to return of incontinence) and erosion (leading to infection of the implant) resulting from the constant pressure. -
Small-Scale Biological and Artificial Multidimensional Sensors for 3D Sensing
Wiley- Small
A vast majority of existing sub‐millimeter‐scale sensors have a planar, 2D geometry as a result of conventional top‐down lithographic procedures. However, 2D sensors often suffer from restricted sensing capability, allowing only partial measurements of 3D quantities. Here, nano/microscale sensors with different geometric (1D, 2D, and 3D) configurations are reviewed to introduce their advantages and limitations when sensing changes in quantities in 3D space. This Review categorizes sensors based…
A vast majority of existing sub‐millimeter‐scale sensors have a planar, 2D geometry as a result of conventional top‐down lithographic procedures. However, 2D sensors often suffer from restricted sensing capability, allowing only partial measurements of 3D quantities. Here, nano/microscale sensors with different geometric (1D, 2D, and 3D) configurations are reviewed to introduce their advantages and limitations when sensing changes in quantities in 3D space. This Review categorizes sensors based on their geometric configuration and sensing capabilities. Among the sensors reviewed here, the 3D configuration sensors defined on polyhedral structures are especially advantageous when sensing spatially distributed 3D quantities. The nano‐ and microscale vertex configuration forming polyhedral structures enable full 3D spatial sensing due to orthogonally aligned sensing elements. Particularly, the cubic configuration leveraged in 3D sensors offers an array of diverse applications in the field of biosensing for micro‐organisms and proteins, optical metamaterials for invisibility cloaking, 3D imaging, and low‐power remote sensing of position and angular momentum for use in microbots. Here, various 3D sensors are compared to assess the advantages of their geometry and its impact on sensing mechanisms. 3D biosensors in nature are also explored to provide vital clues for the development of novel 3D sensors.

PRESSURE-VOLUME PROFILES OF THE ARTIFICIAL URINARY SPHINCTER (AMS 800TM) OCCLUSIVE CUFF
Engineering and Urology Society Annual Meeting 2018
The surgical procedure for implanting the AMS 800TM (American Medical Systems, MN, USA) has been proven safe and effective. However, patients suffer from complications like urethral erosion, atrophy, and infection from the long-term use of the device. The objective of this study was to determine the volume of fluid required to raise the pressure in the occlusive cuff from 40 cmH2O to a pressure of 120 cmH2O (corresponds to the pressure on the bladder during times of stress like coughing/…
The surgical procedure for implanting the AMS 800TM (American Medical Systems, MN, USA) has been proven safe and effective. However, patients suffer from complications like urethral erosion, atrophy, and infection from the long-term use of the device. The objective of this study was to determine the volume of fluid required to raise the pressure in the occlusive cuff from 40 cmH2O to a pressure of 120 cmH2O (corresponds to the pressure on the bladder during times of stress like coughing/ sneezing) which leads to stress urinary incontinence (SUI). The determination of this volume will help in two ways- firstly, characterize cuffs mathematically using the pressure-volume profiles and secondly, design an AUS pump that can adapt to a patient’s level of activity by reducing the pressure most of the day to protect the urethra and briefly increasing the pressure when he is more active.
