What changed
USPTO published a patent application for an intravascular catheter device with an expandable portion comprising struts that can be controllably moved between two positions. In the first position, the mid-portion of each strut extends outward beyond the catheter tube's outer diameter. In the second position, the struts are retracted inward so they extend at or within the outer diameter. The device includes a tip member distal to the expandable portion and a limiter between the expandable portion and the tip member.
This publication does not impose compliance obligations on regulated entities. It represents a routine patent filing by private inventors for a medical device. Healthcare companies, medical device manufacturers, and investors may review the application to assess potential licensing opportunities or competitive implications for existing catheter technologies.

Inventors

Abstract
An intravascular catheter device includes an expandable portion having a proximal common end secured to a distal end of a flexible catheter tube, a distal common end spaced apart from the same, and struts extending therebetween. The expandable portion is controllably moved between a first position where at least a mid-portion of each of the struts is moved outward so as to extend beyond an outer diameter of the catheter tube and a second position where the mid-portion of the struts are moved inward so that the struts extend at or within an outer diameter of the catheter tube. A tip member is located distal to a distal end of the expandable portion, and a limiter is interposed between a distal end of the expandable portion and a proximal end of the tip member.
