URL: https://guides.lib.uci.edu/BME1_Fall2019

Pending Deadlines

There are 3 deadlines for this assignment:

  1. each group to decide which device topic will pursue and what each member's role will be - by Feb 7
  2. identify a device patent and conduct literature review on device - submit Progress Report in form of an annotated bibliography reflecting description of journal articles, and device design that is being re-engineered from patent submission by Feb 12
  3. submit final report by Feb 21.  Final report should reflect a salient patent that is to be modified by adding two new claims that reflect their proposed modifications.

Project 2 - Patent & Regulatory Plans for a Medical Device

For this assignment due February 21, you will select a BME device or technology used in cardiology, conduct a literature search about it and describe the use and operation of the device or technology in a paper.  There are many resources for this and a select list of resources that you can readily find and use follows these notes.  A more extended list of resources is on the Biomedical Engineering Subject Guide or elsewhere in this Course Guide.  Please start by carefully reading the assignment so that you know what is expected of each group.  These notes follow that assignment. 

The Subject Guide for Patents will be particularly helpful and useful.    Remember, patents are defined by jurisdiction, and being awarded a patent takes a long time and patent applications are also included in the US Patent & Trademark Office database. 

It is required that at least   2 members of each group make an appointment with the Engineering Librarian,and as many as possible are encouraged to come especially if you need help in conducting a patent search.  Group Appointments can be scheduled from February 3-6 by registering with your UCI eMail account at http://tinyurl.com/yc9kp7nf

If the above URL does not allow you to click through to sign in, please cut and paste and re-enter in a new browser window. 

Please note that Librarian will be away February 9-12 and 15-19 but is available via eMail. Please try and populate the sessions with as many groups as you can by adding lines to the schedule. A reminder: Even though it is not required it is encouraged that as many group members as possible attend the sessions. 

The device types from which to choose are:

  1.  Tissue-engineered articular cartilage for regenerating focal cartilage lesions - see NeoCart from Histogenics
  2.  Tissue-engineered skin for regenerating skin lesions - see Dermagraft from Organogenesis
  3.  Device for the repair of ligaments and tendons - see JewelACL from Neoligaments
  4.  Orthopaedic external fixators - see TrueLok from Orthofix
  5.  Percutaneous ventricular restoration technology - see Parachute Implant by Cardiokinetix
  6. Heart valve replacement - see Perimount Plus by Edward's Lifesciences

You will choose the disease type or condition that warrants attention that this device can effect:

  • Atherosclerosis
  • Valvular Disease
  • Cardiac Arrhythmia
  • Injury  or Accident, caused by fall, sports or athletic participation
  • Burns or other lasting wounds
  • Skeletal or birth defects

Each group member will participate in the research of the cardiology patient - the symptoms, disease, recommended treatment/therapy; (determine if treating adults or pediatric patients); cover the engineering literature (materials, size of device, effectiveness, etc), data of the marketplace demand because of the global or domestic demand for the device due to incidence rates of specific heart disease or conditon; finding the US patent(s) and how they will be re-engineered, revised or redesigned but they will assume specific responsibilities to focus on the final submission in the following way:

  1. leader - keep everyone on track, project moving forward, meet all deadlines
  2. editor - edit submission to have one common voice
  3. patent researcher - make sure that patent selection meets all criteria
  4. journal researcher - reviews & searches the medical literature making sure the criteria are met (review articles - latest 5 yrs; most current over 1-2 yrs)
  5. curator - synthesizes research process
  6. art director - manages the images and makes sure that new illustrations for the patent redesign are complete and clear

Research should cover:

  • incidence and impact statistics of the disease - see sources under Project 1 for data collected by CDC
  • relevant biological and anatomical features of normal and diseased cases
  • what are the general strategies employed for correcting disease- related malfunctions?
  • select a specific device and design (patent)
  • what specific capability or technology do you propose to add to the patented device?
  • how will the new capability or technology be implemented?

How to Read a Patent

For background information, the Patent FAQ may answer some basic questions.  Use a Patent Glossary if you need help with definitions.  Patents appear to be outlined with numbers - these are Standard Field Codes or "INID codes" for international agreed numbers for the identification of bibliographic data and are consistent with patents from around the world. 

  • Drawings - each figure is numbered and explained  - sometimes they are broken up into several sub-figures and they can also show a 3D view with parts numbered for identification.
  • Specification - the basic text but does not include the claims.  Provides the summary of the invention and describes the drawings.
  • Claims - the most important part of a patent - often written in legalistic style.  Two types of claims: Independent & Dependent where the latter only has meaning when combined with a preceding claim and the former claim stands alone.  Usually the broadest claims of the patent are at the top or front of the list of what the patent is supposed to achieve or do.
