Title: Innovations by Hasan Kar in Vascular Surgery

Introduction

Hasan Kar is a notable inventor based in Berlin, Germany. He has made significant contributions to the field of vascular surgery, holding a total of 3 patents. His work focuses on developing advanced catheter systems that enhance the effectiveness of medical procedures.

Latest Patents

One of Hasan Kar's latest patents is a catheter system for vessel recanalization in the human body. This innovative catheter includes a circular array of optical fibers at its distal end, with each lightguide separated by an elastically deformable member. These compartments can receive pressurized fluid, allowing the diameter of the catheter to expand when pressurized. The optical fibers are strategically bunched at the end of the catheter near the laser light source, where shutters are positioned to select only the necessary lightguides for removing blockages. By pressurizing specific elastically expandable members, groups of optical fibers can be isolated and directed toward the vessel wall during use.

Another significant patent is a process and device for protecting the proximal launch sides of laser catheters fed with short-pulsed laser radiation. In this invention, individual optical fibers are arranged in hexagonally closest packing on the launch side. Ablation-resistant materials are applied to the outer circumference of the cross-section area adjacent to the launch device. These materials, which can be silicate or PTFE, are connected to the optical fibers through material or friction connections, enhancing the durability of the device.
