Abstract
An implantable artificial bronchus including a body having a proximal upper opening and a distal lower opening. The distal lower opening being in fluid communication with the proximal upper opening, and the body at least partially tapering along a length toward the distal lower opening. The body having a plurality of side openings configured to allow air to enter into and exit the implantable artificial bronchus through the body. A length of the body is greater than 4 times the size of a largest diameter of the body, and the diameter of the proximal upper opening is larger than a diameter of the distal lower opening.
Claims29
An implantable artificial bronchus, comprising:
- a body having a proximal upper opening and a distal lower opening in fluid communication with the proximal upper opening, the body at least partially tapering along a length of the body toward the distal lower opening and having a plurality of side openings configured to allow air to enter into and exit the implantable artificial bronchus through the body,
- wherein a length of the body is greater than 4 times the size of a largest diameter of the body and,
- wherein a diameter of the proximal upper opening is larger than a diameter of the distal lower opening.
An implantable artificial bronchus, comprising:
- a body having a proximal upper opening and a distal lower opening in fluid communication with the proximal upper opening, the proximal upper opening tapering towards a central axis of the body, and the body constantly tapering from a portion proximate the proximal upper opening toward a portion proximate the distal lower opening, and having a plurality of side openings configured to allow air to enter into and exit the implantable artificial bronchus through the body, the body comprising:
- a proximal portion being tapered toward a central axis of the body;
- a first middle portion having a first middle taper;
- a second middle portion having a second middle taper larger than the first middle taper;
- and
- a distal portion having a constant distal diameter, wherein the first middle portion and the second middle portion are disposed between the proximal portion and the distal portion;
- wherein a diameter of the proximal upper opening is at least twice as large as a diameter of distal lower opening, and the diameter of the proximal upper opening is less than a maximum diameter of the body, the maximum diameter of the body being proximate the proximal upper opening, and
- wherein in an implanted state the body is configured to curve in a first radial direction along a first length of the body and a second radial direction opposite the first radial direction along a second length of the body.
