  • Keyword Index to Assist Manufacturers in Verifying the Class of Medical Devices
    September 12, 2006 NOTICE Our file number: 06-120629-368 Re: Keyword Index to Assist Manufacturers in Verifying the Class of Medical Devices Health Canada is pleased to announce the release of the revised Keyword Index to Assist Manufacturers in Verifying the Class of Medical Devices. This guidance document supersedes the January 14, 2000 version of the same document. The Keyword Index to Assist Manufacturers in Verifying the Class of Medical Devices is intended to assist manufacturers in confirming the classification of medical device products after application of the Classification Rules for Medical Devices set out in Schedule 1 of the Medical Devices Regulations. This guidance document has been revised to reflect changes to the risk- based classification of particular medical device groups. Specifically, the following major changes have been made to the document: • the reclassification of specific medical device groups; • the removal of redundant information; • the addition of medical device groups; and • the omission of product groups that do not fit the meaning of a medical device as defined in the Food and Drugs Act. To search for a medical device group within the Keyword Index to Assist Manufacturers in Verifying the Class of Medical Devices PDF file, go to Edit/Find and enter a keyword, preferred name code or description in the “Find” field. For instance, to verify the risk-based classification of dental burs, enter “bur” or “drill” in the “Find” field. Please note that this guidance document is provided only as a guide and that in the event of any discrepancy between this document and the Classification Rules for Medical Devices described in the Medical Devices Regulations, the latter shall prevail.

  • Biodegradable Surgical Staple Composed of Magnesium Alloy

This paper proposes a novel biodegradable magnesium (Mg) alloy staple and discusses analyses conducted to evaluate its safety and feasibility. Specifcally, fnite element analysis revealed that the proposed staple has a suitable stress distribution while stapling and maintaining closure. Further, an immersion test using artifcial intestinal juice produced satisfactory biodegradable behavior, mechanical durability, and biocompatibility in vitro. Hydrogen resulting from rapid corrosion of Mg was observed in small quantities only in the frst week of immersion, and most staples maintained their shapes until at least the fourth week. Further, the tensile force was maintained for more than a week and was reduced to approximately one-half by the fourth week. In addition, the Mg concentration of the intestinal artifcial juice was at a low cytotoxic level. In porcine intestinal anastomoses, the Mg alloy staples caused neither technical failure nor such complications as anastomotic leakage, hematoma, or adhesion. No necrosis or serious infammation reaction was histopathologically recognized. Thus, the proposed Mg alloy staple ofers a promising alternative to Ti alloy staples. Intestinal anastomosis using staples is widely practiced in surgery nowadays1–4. Staples used for this procedure are primarily composed of non–biodegradable titanium (Ti) alloy.

Cello, MD1 and Stanley J. Rogers, MD1 The gastroenterologist, whether in academic or clinical practice, must face the reality that an increasingly large percentage of adult patients are morbidly obese. Morbid obesity is associated with significant morbidity and mortality including enhanced morbidity from cardiovascular, cerebrovascular, hepatobiliary and colonic diseases. Most of these associated diseases are actually preventable. Based on the 1991 NIH consensus conference criteria, for most patients with a body mass index (BMI ¼ weight in kilograms divided by the height in meters squared) of 40 or more, or for patients with a BMI of 35 or more and significant health complications, surgery may be the only reliable option. Currently in the United States, over 250,000 bariatric surgical procedures are being performed annually. The practicing gastroenterologist in every community, large and small, must be familiar with the various surgical procedures together with their associated anatomic changes.

Positioned buttress material(s) are delivered to a tissue site where the circular stapler is actuated to connect previously severed tissue portions. An embodiment of the invention allows tissue portions to be joined without the use of sutures. The buttress material is made up of two regions, one of which serves primarily to secure the buttress material to the stapler prior to actuation, and one of which serves 2010200618 10 primarily to form the improved seal. The former region is severed and discarded upon activation of the circular stapler to form anastomoses, while the remaining material secures and seals the newly connected tissue.

    DEVELOPMENT OF ELECTRONIC INSTRUMENTATION FOR COMPUTER-ASSISTED SURGERY by Kaci Carter A thesis submitted to the Department of Electrical and Computer Engineering In conformity with the requirements for the degree of Master of Applied Science Queen’s University Kingston, Ontario, Canada (August, 2015) Copyright ©Kaci Carter, 2015 Abstract In the operating room, feedback, such as instrument positioning guidance provided by surgical navigation systems is typically displayed on an external computer monitor. The surgeon’s attention is usually focused on the surgical tool and the surgical site, so the display is typically out of the direct line of sight. A simple visual feedback mechanism was developed to be mounted on the surgical tool. This feedback is within the surgeon’s direct line of sight and alerts the surgeon when it is necessary to look at the monitor for detailed navigation information. The combination of visual feedback with the surgical navigation system is designed to aid the surgeon in cutting around a tumor, maintaining negative margins, while reducing the amount of healthy tissue contained within the cut. The tool- mounted visual feedback device was designed to be light-weight, compatible with electromagnetic (EM) tracking, and pose no risk of galvanic connection to the patient. The device was tested through the resection of multiple tumor contour models using computer navigation screen only, and computer navigation screen with visual feedback mounted on the surgical tool. Use of the device was shown to decrease the amount of healthy tissue contained within the surgical cut, and to increase the subjects’ confidence in their ability to follow acceptable margins.
