Abstract:
1. A lumen measuring device for measuring at least an inside diameter of a lumen by extending the device into the lumen, said lumen measuring device comprising: a) an elongate central member having a proximal end and a distal end; and b) an elongate outer member having a proximal end and a distal end and being integrally formed from a single piece of tubular material, the outer member including, c) wherein flexing of said flexible region causes it to contact the lumen and indicate the inside diameter of the lumen, and d) a first handle portion coupled to the central member and a second handle portion coupled to the outer member, wherein the first and second handle portions are displaceable with respect to one another, and e) a first part of the first handle portion being disposed within the second handle portion, the first part of the first handle portion having proximal and distal ends, f) wherein displacement of the first handle portion in the proximal direction relative to the second handle portion is limited by contacting the proximal end of the first part of the first handle portion with a first part of the second handle portion disposed proximal to the first part of the first handle portion, and g) wherein displacement of the first handle portion in the distal direction relative to the second handle portion is limited by contacting the distal end of the first part of the first handle portion with a second part of the second handle portion disposed distal to the first part of the first handle portion, and h) a second part of the first handle portion extending out of the second handle portion and comprising a first loop configured to receive a first user's finger, and i) a third part of the first handle portion extending out of the second handle portion opposite the second part of the first handle portion, the third part of the first handle portion comprising a second loop configured to receive a second user's finger, j) wherein the second handle portion comprises a third loop configured to receive a user's thumb, the third loop being disposed proximal to the first part of the second handle portion.
