International Classification:

A62B 9/06
A61M 16/00

US Classification:

12820714, 12820026

Abstract:

There is provided a balloon cuffed tracheostomy tube with a balloon designed so as to enhance the tube's anchorability without sealing the tracheal stoma. The tracheostomy tube device includes a conventional curved hollow tube. The distal end of the tube is adapted for insertion through a tracheal stoma and into the tracheal lumen of a patient's throat. The device further includes an inflatable balloon enveloping a portion of the tube. The balloon has a distal portion substantially centered about and attached to the distal end portion of the tube. The balloon also has a proximal portion attached to the bend region of the tube and positioned substantially off-center relative to the proximal portion of the tube and about the bend region below the proximal plane of the device. Upon inflation, this configuration provides for expansion of the balloon around the distal end portion of the tube and the proximal end portion of the tube below the proximal plane of the device to seal the trachea below the tracheal stoma and to avoid sealing the trachea above the tracheal stoma. This configuration of the balloon should allow secretions to exit the stoma so that they do not accumulate and become a possible source of ventilator acquired pneumonia.

International Classification:

US Classification:

12820714, 12820026

Abstract:

There is provided a balloon cuffed tracheostomy tube with a balloon designed so as to enhance the tube's anchorability without sealing the tracheal stoma and to allow for an easier insertion into the trachea than a comparable tube with a thicker balloon. The tracheostomy tube device includes a conventional hollow tube having a proximal end portion, a distal end portion, and a bend region intermediate of the end portions. The distal end portion of the tube is arranged for insertion through a patient's throat and tracheal stoma and into the tracheal lumen. The device further includes an inflatable balloon enveloping a portion of the tube. More particularly, the balloon is equal to or less than 30 microns in thickness, allowing for a greater ease of insertion and insertion through a smaller stoma opening, than a comparable tube with a balloon having a thickness greater than 30 microns.

International Classification:

A61B 17/32
A61M 29/00

US Classification:

606167, 606191

Abstract:

There is provided a device for performing an initial piercing and dilating of a patient's trachea. The device has a needle within and extending beyond a sheath. After the needle is used to pierce the trachea, it may be removed and a guide wire (J-wire) inserted. A introducer dilator surrounds the sheath and is slidable over the sheath. The introducer dilator has a first position away from the distal end of the sheath and a second position in which the distal end of the sheath is substantially covered by the introducer dilator. The introducer dilator is then used to expand the initial piercing.

International Classification:

A61M 16/00

US Classification:

12820714

Abstract:

There is provided a novel tracheostomy tube flange. The flange is made of a flexible material and has a large open area for viewing of the underlying skin. The flange has holes for suturing the flange to the skin and slots for attachment of a strap to surround the neck and keep the flange and tube in place. The flange may swivel on the tube to allow for greater flexibility in attaching it to the skin. A stoma pad may be used with the flange to help keep the skin under the flange healthy.

International Classification:

A61M 16/04

US Classification:

12820714

Abstract:

There is provided an improved tracheostomy tube having a proximal section over-molded by a distal section, where the sections have a differential in the degree of radio-opacity. The radio-opaque material allows a medical professional to determine the location of the tube in the trachea non-invasively, using an x-ray or similar device. In addition, aligning the top (proximal end) of the balloon with the transition between the distal and proximal sections of the tube allows a medical professional to know the exact location of the balloon. The length of the proximal section may be set so that the balloon is place in a pre-determined position so that the transition point between the distal and proximal sections may be used as a position indicator.

International Classification:

A61B 17/34

US Classification:

12820729

Abstract:

There is provided a device for performing an initial piercing and dilating of a patient's trachea. The device has a needle within and extending beyond a sheath which in turn is within and extends beyond an introducer dilator. After the needle is used to pierce the trachea, it may be removed and a guide wire (J-wire) inserted through the introducer dilator and sheath in its place. The sheath is slidable within the introducer dilator once the needle is removed. The introducer dilator is then moved forward, into the site of the initial piercing to expand it. As the introducer dilator is moved forward, the sheath may remain stationary, sliding within the introducer dilator and thus reducing trauma to the stoma site.
