  • Publication number: 20150150642
    Abstract: Various embodiments of the present disclosure are directed to apparatuses, devices, and procedures for unsedated in-office tracheoesophageal puncture (TEP) using transnasal esophagoscopy (TNE) and a measurement cannula, referred to as a TEP measurement and insertion device (MAID or TEP MAID). In some embodiments, a MAID is configured for use with a mini-tracheostomy kit; in other embodiments, a MAID is configured to be carried and automatically or semi-automatically deployed, for instance, by a handheld mechatronic device or an automated device such as a medical robot that carries an automated tracheoesophageal puncture and voice prosthesis insertion end effector. In accordance with an aspect of the present disclosure, a MAID has a body that carries or includes indicators, indicia, or markings that facilitate or enable substantially direct and/or immediate estimation, identification, or measurement of a tissue extent or thickness corresponding to or across a tracheoesophageal fistula (e.g.

  • Patent number: 8925494
    Abstract: Edible animal chew and method of using the animal chew. The animal chew is edible and is configured to clean laniaries and gum tissue of an animal as the animal chews and eats the animal chew. The animal chew comprises all-natural ingredients and is, therefore, free of synthetic ingredients and unhealthy added ingredients, such as added sugars. The animal chew may further contain all-natural vitamins for improving health of the animal. A plurality of first projections and second projections on a proximal end portion and a distal end portion, respectively, are provided to clean laniaries and gum tissue for reducing risk of tooth decay and periodontal disease. A plurality of raised nodules is also provided on the distal end portion for massaging gum tissue to reduce risk of periodontal disease.

  • Publication number: 20140188135
    Abstract: The present disclosure includes a bio-absorbable wound closure clip for wound closure without crushing of the tissue being closed. The bio-absorbable wound closure clip can be used in minimal access surgery as well as on tissue, such as mucosal tissue, where tactile feedback is reduced. Representative surgical instruments for applying the bio-absorbable wound closure clip and methods of using the same are also provided herein.
