Devices for retrieving an obstruction in a bodily duct of a patient

A device for capturing an obstruction in a bodily duct of a patient, the device comprising:

• a cylindrical body having a circumference and a longitudinal axis and including a plurality of cell structures formed by struts, a majority of the plurality of cell structures being of the same size and shape and arranged in diagonal rows around the longitudinal axis, the plurality of cell structures including first, second, third, fourth and fifth cell structures, the first cell structure being surrounded by the second, third, fourth and fifth cell structures and sharing at least one strut with each of the second, third, fourth and fifth cell structures, the plurality of cell structures each includes first, second, third, fourth, fifth and sixth struts, each of the first, second, third, fourth, fifth and sixth struts having a proximal end and a distal end,
• the proximal end of the first strut being coupled to the proximal end of the second strut at a first longitudinal location, the distal end of the third strut being coupled to the distal end of the fourth strut at a second longitudinal location distal to the first longitudinal location, the distal end of the first strut being coupled to the proximal end of the fifth strut at a third longitudinal location, the proximal end of the third strut being coupled to the distal end of the fifth strut at a fourth longitudinal location, the distal end of the second strut being coupled to the proximal end of the sixth strut at a fifth longitudinal location, the proximal end of the fourth strut being coupled to the distal end of the sixth strut at a sixth longitudinal location, the fourth longitudinal location being proximal to the sixth longitudinal location, the proximal and distal ends of the fifth strut being longitudinally aligned with one another and residing at a first circumferential location, the proximal and distal ends of the sixth strut being longitudinally aligned with one another and residing at a second circumferential location, the second circumferential location being spaced apart from the first circumferential location, when the device is cut longitudinally and laid flat on a surface at least a first portion of each of the first, second, third and fourth struts is curved and at least a second portion of each of the first, second, third and fourth struts is straight, none of the first, second, third and fourth struts extending circumferentially beyond the first circumferential location and the second circumferential location;
• wherein a first of the plurality of cell structures and a second of the plurality of cell structures occupy a same circumferential location and are longitudinally separated by no less than four diagonal rows, the second of the plurality of cell structures being located nearer the first of the plurality of cell structures than any of another of the plurality of cell structures that are longitudinally aligned with the first of the plurality of cell structures.

• a first antenna having a proximal end and a distal end, the cylindrical body coupled to the distal end of the first antenna, when the device is cut longitudinally and laid flat on a surface at least a portion of the first antenna is straight, the at least a portion of the first antenna being longitudinally aligned with the proximal and distal ends of at least one of the fifth struts and/or with the proximal and distal ends of at least one of the sixth struts.
