Researchers Submit Patent Application, "Limited-Use Medical Device", for Approval

August 7, 2014



By a News Reporter-Staff News Editor at Politics & Government Week -- From Washington, D.C., VerticalNews journalists report that a patent application by the inventors JOSEPH, DANIEL A. (GOLDEN, CO); JOSEPH, LESLIE M. (GOLDEN, CO), filed on November 21, 2013, was made available online on July 24, 2014.

The patent's assignee is Covidien Lp.

News editors obtained the following quote from the background information supplied by the inventors: "The present disclosure relates to medical devices. More particularly, the present disclosure is directed to limited-use medical devices and medical devices including limited-use portions.

"Certain medical devices (or components thereof) are capable of being used multiple times, and are thus referred to as reusable devices (or reusable components), while other medical devices (or components thereof) are configured for single use, and are thus referred to as disposable devices (or disposable components). Many such reusable and disposable medical devices, and/or the components thereof, are designed for a pre-determined number of uses and/or for a pre-determined usage time. Use of these devices beyond their prescribed usage time or number of uses may result in failure of the device, damage to the device or surrounds, and/or injury to the patient or clinician. On the other hand, given the rising costs of performing medical procedures, clinician's have an incentive to maximize the reuse of medical devices (or components thereof)."

As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventors' summary information for this patent application: "Like reference numerals may refer to similar or identical elements throughout the description of the figures. As shown in the drawings and described throughout the following description, as is traditional when referring to relative positioning on a surgical instrument, the term 'proximal' refers to the end of the apparatus that is closer to the user and the tem 'distal' refers to the end of the apparatus that is farther away from the user. The term 'clinician' refers to any medical professional (e.g., doctor, surgeon, nurse, or the like) performing a medical procedure. To the extent consistent, any of the aspects and features described herein may be used in conjunction with any or all of the other aspects and features described herein.

"In accordance with the present disclosure, a medical device is provided including one or more operable components, and one or more limited-use portions. The limited-use portions are configured to transition from a first state to a second state upon being subjected to sterilization above a sterilization threshold. In the second state, the limited-use portion(s) inhibit the operability of one or more of the operable components, thereby rendering the medical device inoperable.

"In one aspect, sterilization of the limited-use portion above the sterilization threshold renders the medical device mechanically inoperable.

"In another aspect, sterilization of the limited-use portion above the sterilization threshold renders the medical device electrically inoperable.

"In another aspect, sterilization includes use of a chemical sterilization process. In such aspects, the limited-use portion is sensitive to one or more of the chemicals used in the chemical sterilization process.

"In another aspect, the chemical sterilization process includes the use of one or more chemical sterilizers, e.g., hydrogen peroxide, water, saline, alcohol, ethylene oxide, ozone, bleach, chlorine, glutaraldehyde, formaldehyde, phthalaldehyde, silver, triclosan, and/or combinations thereof. The limited-use portion transitions to the second state due to contact with one or more of these chemical sterilizers.

"In another aspect, sterilization includes use of an autoclave. In such aspects, the limited-use portion transitions to the second state due to autoclaving.

"In another aspect, sterilization includes the use of an energy-based sterilization process. In such aspects, the limited-use portion transitions to the second state due to exposure to the energy-based sterilization process.

"In another aspect, sterilization includes a high temperature sterilization process having a sterilization temperature. In such aspects, the limited-use portion transitions to the second state at a temperature equal to or below the sterilization temperature.

"In another aspect, the limited-use portion further includes one or more temperature fuses connected to one or more electrical components thereof. The temperature fuse is configured to transition to the second state at a temperature equal to or below the sterilization temperature.

"In another aspect, the medical device includes a housing, a pair of jaws for clamping tissue, a pivot pin rotatably connecting the jaws, and at least one electrode connected to said jaws for applying energy to tissue. In such aspects, the housing, jaws, pivot pin, and/or electrode include a limited-use portion.

"A method provided in accordance with aspects of the present disclosure includes providing a medical device including one or more operable components and one or more limited-use portions. The method further includes subjecting the medical device to sterilization above a sterilization threshold, thereby transitioning the limited-use portion from a first state to a second state. In the second state, the limited-use portion inhibits the operability of one or more of the operable components, thereby rendering the medical device inoperable. The method may further include any of the features described above with respect to the previous aspects.

BRIEF DESCRIPTION OF THE DRAWINGS

"The above and other aspects, features, and advantages of the present disclosure will become more apparent in light of the following detailed description when taken in conjunction with the accompanying drawings, wherein:

"FIG. 3A is a perspective view of another a medical device provided in accordance with the present disclosure, shown before sterilization;

"FIG. 3B is a perspective view of the medical device of FIG. 3A, shown after sterilization;

"FIG. 3C is a perspective view of an opened half of a housing of a medical device provided in accordance with the present disclosure, shown before sterilization;

"FIG. 3D is a perspective view of the opened half of the medical device of FIG. 3C, shown after sterilization;

"FIG. 4A is a perspective view of an end effector assembly provided in accordance with the present disclosure and configured for use with the medical device of FIG. 1, shown before sterilization;

"FIG. 4B is an perspective view of the end effector assembly of FIG. 4A, shown after sterilization;

"FIG. 4C is an exploded view of another end effector provided in accordance with the present disclosure and configured for use with the medical device of FIG. 1, shown before sterilization;

"FIG. 4D is an exploded view of the end effector assembly of FIG. 4C, shown after sterilization;

"FIG. 5A is a perspective view of an opened half of a housing of a medical device provided in accordance with the present disclosure, shown before sterilization;

"FIG. 5B is a perspective view of the opened half of the medical device of FIG. 5A, shown after sterilization;

"FIG. 6A is a perspective view of a medical device provided in accordance with the present disclosure, shown before sterilization; and

"FIG. 6B is a perspective view of the medical device of FIG. 6A, shown after sterilization."
