Title: Har'el Rosen: Innovator in Medical Technology

Introduction

Har'el Rosen is a notable inventor based in Cherry Hill, NJ (US), recognized for his contributions to medical technology. With a total of two patents to his name, he has made significant advancements in catheter design and light-activated switching mechanisms.

Latest Patents

One of Har'el Rosen's latest patents is for a catheter with a distally located integrated circuit radiation generator. This innovative catheter features at least two electrical conductors extending from the proximal to the distal ends. A semiconductor chip generator of electromagnetic radiation is located at the distal end and is energized by electrical power supplied by the conductors. The chip may function as a laser or include an oscillator for generating electromagnetic radiation at selected frequencies. In one embodiment, two chip radiation generators are positioned distally, each connected to one of the conductors, allowing for independent energization. Additionally, an axial aperture may be provided for a guide wire, and a balloon may surround the distal end of the catheter, which can be inflated through another axial aperture.

Another significant patent by Rosen is for a high voltage switch structure with a light-responsive diode stack. This invention involves a light-activated PIN diode switch arrangement that is coupled to a source of direct voltage and a load for controlling the flow of load current. The PIN diode switch is designed to be electrically reverse-biased, preventing current flow until activated by a light source. The configuration provides high power and low inductance by physically and electrically connecting two PIN diode sets together with a conductive heat sink. Laser diode arrays above and below the diodes selectively illuminate the intrinsic region of each diode, enhancing their functionality.
