Title: Innovations by Cassandra A. Piippo in Rotational Atherectomy Devices
Introduction
Cassandra A. Piippo is an accomplished inventor based in Hugo, MN, known for her significant contributions to the field of medical devices, particularly in rotational atherectomy technology. With a total of three patents to her name, she has developed innovative solutions aimed at improving patient outcomes in cardiovascular procedures.
Latest Patents
One of her latest patents is the "Bidirectional Expandable Head for Rotational Atherectomy Device." This invention features an expandable head capable of cleaning blockages from vessels larger than its rest diameter. The device includes a drive shaft that can rotate in two opposite directions, each with distinct abrasive characteristics. In one direction, the head is designed for cutting and slicing, making it effective for removing soft blockage material. Conversely, in the other direction, it is configured for grinding, scraping, and sanding, which is ideal for hard blockage material. The head comprises one or more arms that are pivotally attached to the drive shaft, with abrasive elements designed to cut and grind effectively.
Another notable patent is the "Directional Rotational Atherectomy Device with Offset Spinning Abrasive Element." This invention provides a flexible, elongated, rotatable drive shaft with a pre-curved abrasive section. The design allows the abrasive section to deform to a straight profile within a catheter and resume its pre-curved shape when moved distally. This innovative approach enables directional ablation by rotating the drive shaft along its pre-curved axis against the lumen wall.
