The present invention relates to a method of preparing a tissue graft material. The invention also relates to a multipurpose tissue graft material and to methods of using same as a replacement for vascular and non-vascular tissue.
摘要:
An earpiece and method to control a level of audio reproduction within an occluded ear canal are provided. The method includes the steps of measuring an ambient sound level from an Ambient Sound Microphone (ASM) at an entrance to an occluded ear canal, measuring a residual background noise level within an occluded ear canal from an Ear Canal Microphone (ECM), measuring a level of audio content delivered to the occluded ear canal, and adjusting a gain of the audio content so as to maintain reproduction of the audio content within a predetermined level range.

A method is provided for preparing a tissue implant for implantation. The method includes harvesting a tissue material from a human or an animal donor, treating the tissue material with water or a hypotonic solution to lyse native cells of the tissue material, treating the tissue material in a nuclease-containing solution which includes an antimicrobial, treating the tissue material with an alkaline alcohol solution, treating the tissue material with a chlorine dioxide treatment solution, and sterilizing the tissue material.
摘要:
A method for an earpiece to manage a delivery of a message can include receiving a notice that a message is available at a communication device, parsing the notice for header information that identifies at least a portion of the message, and requesting a subsequent delivery of at least a portion of the message from the communication device if at least one keyword in the header information is in an acceptance list. Other embodiments are disclosed.
摘要:
At least one exemplary embodiment is directed to a method of auditory communication comprising: measuring a data set; identifying the type of data set; obtaining the auditory cue associated with the type of data set; and generating an auditory notification; and emitting the auditory notification.

A spinous process spacer implant for relief of back pain is disclosed. The implant, a generally H-shaped device having grooved ends, is made of human allograft or other suitable artificial or natural material. It is sized for implantation between and optional attachment to adjacent spinous processes. The implant may be hollow in the center to allow for addition of suitable biological material.
摘要:
A method and apparatus to cover openings in a plurality of materials is described. In one embodiment, a disc shaped member includes a three-stepped surface having an outer, second, and inner surface, is configured to fit into and cover an existing opening. The outer surface is sized larger than the opening being covered. The second surface being sized to fit within such opening. The inner surface being the smallest and includes a blind hole for the insertion of a bolt. The bolt and an inner member cooperate such that the disk shaped member may be lined up with an inside surface of an opening of virtually any material or object configured to accept such a disk shaped member. Once the disk shaped member is fastened onto the exterior surface of a doorframe using a bolt and the inner member, for example, the existing hole being covered will no longer be visible or accessible, thereby beautifying, covering, and securing the object.
摘要:
A closed, sterile pulsatile flow loop for studying tissue valves. The system provides both a tool to examine heart valve leaflet fibroblast function and differentiation as these are affected by mechanical loading, as well as an apparatus to provide heart valves seeded with suitable cells. The sterile pulsatile flow system provides a left heart duplicator, which exposes viable tissue valves to a dynamic flow environment imitating that of the aortic valve.

This disclosure includes a method for generating a functional hybrid bioprosthesis. Tissue formed naturally of interstitial collagens is treated to kill native cells and remove potentially immunologically active soluble molecules. Then it may be treated sequentially with extracellular matrix adhesion factor, extracellular matrix glycosaminoglycan, and growth factor appropriate to the cell type required to function within the matrix, and incubating the transplant tissue matrix with cells that are either allogeneic or autologous for the recipient thereby imparting to the matrix the characteristics of the cell type and tissue selected. Tissues with a variety of functional bioactivities can thus be formed in vitro prior to graft transplantation or implantation which will exhibit reduced or no stimulation of an immunological response in the recipient.

This disclosure includes a method for generating a functional hybrid bioprosthesis. Tissue formed naturally of interstitial collagens is treated to kill native cells and remove potentially immunologically active soluble molecules. Then it may be treated sequentially with extracellular matrix adhesion factor such as fibronectin, extracellular matrix glycosaminoglycan such as heparin, and growth factor appropriate to the cell type required to function within the matrix, and incubating the transplant tissue matrix with cells that are either allogeneic or autologous for the recipient thereby imparting to the matrix the characteristics of the cell type and tissue selected. Tissues with a variety of functional bioactivities can thus be formed in vitro prior to graft transplantation or implantation which will exhibit reduced or no stimulation of an immunological response in the recipient.
