Abstract:
1. A system for removing objects adhered to a wall of an interior lumen of an animal, the system comprising: a pull wire having a proximal end and a distal end; a distal body attached to said pull wire, said distal body comprising an interior, an exterior, a proximal end, a distal end, a plurality of proximal memory metal strips located at said proximal end, a proximal hub located in said distal body interior, and a distal hub located distal relative to said proximal hub, said distal body having a relaxed state wherein said distal body has a first height and width, and a collapsed state wherein said distal body has a second height and width, said second height less than said first height, said second width less than said first width; a catheter having an interior, a proximal end leading to said interior and a distal end leading to said interior, said catheter comprised of a biocompatible material and configured to envelope said distal body when said distal body is in said collapsed state; wherein each of said proximal memory metal strips has a proximal end and a distal end, wherein, in said relaxed state, each of said proximal ends of said memory metal strips is located proximal relative to said proximal hub, wherein, in said relaxed state, said proximal ends of said proximal memory metal strips are configured to move towards each other and towards said pull wire, while remaining a fixed distance from said distal hub, by moving said proximal hub distally towards said distal hub, wherein, in said relaxed state, said proximal ends of said proximal memory metal strips are configured to move away from each other and away from said pull wire, by moving said proximal hub proximally and away from said distal hub, and wherein said proximal memory metal strips are configured to remove an object adhered to a wall of an interior lumen of an animal.
