  • Publication number: 20230267854
    Abstract: An anatomical movement simulation assembly and a method of simulating anatomical movements. One or more additive-manufactured body part models anatomically approximates a corresponding physical body part(s), or exhibits anatomical accuracy relative to the corresponding physical body part(s). The physical body part(s) modeled include a rib cage, lungs, diaphragm, tongue, jaw and teeth, vocal folds, and larynx, among other possibilities. Movement is imparted to the additive-manufactured body part model(s), for instance via pump, motor, or manual actuation, in order to replicate the physiologically normal movement of the corresponding physical body part(s). Educators, musicians, singers, actors, students, doctors, and patients, as well as others, may find productive use observing such anatomical movement simulations.

  • Publication number: 20230172706
    Abstract: Ear implants for auricular tissue reconstruction in a patient are provided. The ear implant may be a tissue scaffold multicomponent assembly for reconstruction of auricular tissue. Thus, the assembly may include both a first and a second tissue scaffold component. Each comprises a biocompatible polymeric material having a plurality of open pores configured to support cell growth. The first tissue scaffold component defines a central void region and at least a portion of an outer ear framework of the patient after implantation. The second tissue scaffold component defines a base portion. After implantation into the patient, the second tissue scaffold component seats within the central void region of the first tissue scaffold component, so that the second tissue scaffold component is secured to the first tissue scaffold component. Methods for reconstructing auricular tissue in a patient using such ear implant tissue scaffolds are also provided.

  • Patent number: 11337862
    Abstract: An ear splint for an ear is provided having a central portion having an exterior surface defining a first topology that is configured to dwell within an anterior scaphoid section of an ear, and a wing portion extending from the central portion and integrally formed therewith and at least partially surrounding an outer periphery of the central portion. The wing portion includes an exterior surface defining a second topology and is configured to be positioned along a postauricular area of the ear. The first magnetic device is disposed in the central portion and the second magnetic device is disposed in the wing portion.

  • Publication number: 20210299388
    Abstract: A system for providing mechanical ventilation to a plurality of patients using a single ventilator is provided. The system includes a first branched adapter may be coupled to a ventilator, the first branched adapter having a plurality of branches and configured to divide a ventilator gas stream into a plurality of gas streams for delivery to a respective plurality of patients. The system includes a pressure regulator in fluid communication with one branch of the first branched adapter and with one patient, the pressure regulator being configured to reduce the pressure of the gas stream reaching the patient such that it is less pressurized than the ventilator gas stream. The system includes a second branched adapter may be coupled to a ventilator, the second branched adapter having a plurality of branches and configured to unite expired gas streams from the plurality of patients into a single expiratory gas stream.

  • Patent number: 8916360
    Abstract: The present invention provides conjugates between erythropoietin and PEG moieties. The conjugates are linked via an intact glycosyl linking group interposed between and covalently attached to the peptide and the modifying group. The conjugates are formed from glycosylated peptides by the action of a glycosyltransferase. The glycosyltransferase ligates a modified sugar moiety onto a glycosyl residue on the peptide. Also provided are methods for preparing the conjugates, methods for treating various disease conditions with the conjugates, and pharmaceutical formulations including the conjugates.

  • Patent number: 8911967
    Abstract: The present invention provides conjugates between peptides and PEG moieties. The conjugates are linked via an intact glycosyl linking group that is interposed between and covalently attached to the peptide and the modifying group. The conjugates are formed from both glycosylated and unglycosylated peptides by the action of a glycosyltransferase. The glycosyltransferase ligates a modified sugar moiety onto either an amino acid or glycosyl residue on the peptide. Also provided are pharmaceutical formulations including the conjugates. Methods for preparing the conjugates are also within the scope of the invention.
