1. A tracheostomy dilator comprising:
a distal portion having a curve extending to a distal opening and configured to dilate a tracheostomy tracheostoma;
a handle portion proximal of the distal portion and configured to be grasped by a user;
a lumen configured to receive a guidewire; and
a proximal portion proximal of the handle portion and having a proximal opening in communication with the lumen, wherein the proximal portion is configured to deflect the guidewire at an angle of at least 30 degrees from a longitudinal axis of the handle portion,
wherein the proximal portion has a bevel in a circumferential wall at the proximal opening, such that the circumferential wall extends further proximally at an upper portion than a lower portion.
 
15. A tracheostomy dilator comprising:
a distal portion having a curve extending to a distal opening and configured to dilate a tracheostomy;
a handle portion proximal of the distal portion and configured to be grasped by a user;
a lumen configured to receive a guidewire; and
a proximal portion proximal of the handle portion and having a proximal opening in communication with the lumen, wherein the proximal portion is configured to deflect the guidewire at an angle of at least 30 degrees from a longitudinal axis of the handle portion,
wherein the proximal opening is disposed at the angle from the longitudinal axis, and
wherein the proximal portion has a bend from the longitudinal axis to the angle.
 
16. A tracheostomy dilator comprising:
a distal portion having a curve extending to a distal opening and configured to dilate a tracheostomy;
a handle portion proximal of the distal portion and configured to be grasped by a user;
a lumen configured to receive a guidewire; and
a proximal portion proximal of the handle portion and having a proximal opening in communication with the lumen, wherein the proximal portion has a bevel,
wherein the bevel is in a circumferential wall at the proximal opening, such that the circumferential wall extends further proximally at an upper portion than a lower portion.
