Abstract

A medical device may include one or more operable components and one or more limited-use portions. The limited-use portion(s) is 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 the one or more operable components.

Claims (28)

1. A medical device, comprising:

at least one operable component including:

a housing;

a pair of jaws coupled to the housing and configured for clamping tissue; and

at least one electrode connected to the jaws for applying energy to tissue; and

at least one limited-use portion incorporated into at least one of the housing, the jaws, or the at least one electrode, wherein the limited-use portion is configured to transition from a first state to a second state upon being subjected to sterilization above a sterilization threshold, wherein, in the second state, the at least one limited-use portion is at least one of degraded, dissolved, broken down, or destroyed, to inhibit the operability of the at least one operable component.

2. The medical device of claim 1 , wherein sterilization of the limited-use portion above the sterilization threshold renders the medical device mechanically inoperable.

3. The medical device of claim 1 , wherein sterilization of the limited-use portion above the sterilization threshold renders the medical device electrically inoperable.

4. The medical device of claim 1 , wherein sterilization includes use of a chemical sterilization process, and wherein the limited-use portion is sensitive to at least one chemical used in the chemical sterilization process.

5. The medical device of claim 4 , wherein the chemical sterilization process includes the use of at least one chemical sterilizer selected from the group consisting of hydrogen peroxide, water, saline, alcohol, ethylene oxide, ozone, bleach, chlorine, glutaraldehyde, formaldehyde, phthalaldehyde, silver, and triclosan, and wherein the limited-use portion is configured to at least one of degrade, dissolve, break down, or destruct due to contact with at least one of the at least one chemical sterilizers.

6. The medical device of claim 1 , wherein sterilization includes use of an autoclave, and wherein the limited-use portion is configured to at least one of degrade, dissolve, break down, or destruct due to autoclaving.

7. The medical device of claim 1 , wherein sterilization includes the use of at least one energy-based sterilization process, and wherein the limited-use portion is configured to at least one of degrade, dissolve, break down, or destruct due to exposure to the at least one energy-based sterilization process.

8. The medical device of claim 1 , wherein sterilization includes a high temperature sterilization process having a sterilization temperature, and wherein the limited-use portion is configured to at least one of degrade, dissolve, break down, or destruct at a temperature equal to or below the sterilization temperature.

9. The medical device of claim 8 , wherein the limited-use portion further includes at least one temperature fuse connected to at least one electrical component of the at least one operable component, the temperature fuse configured to at least one of degrade, dissolve, break down, or destruct at a temperature equal to or below the sterilization temperature.

10. A method, comprising:

subjecting at least one of a handle assembly, a shaft, or an end effector of a medical device to sterilization above a sterilization threshold, thereby transitioning a limited-use portion of at least one of the handle assembly, the shaft, or the end effector of the medical device from a first state to a second state, wherein, in the second state, the at least one limited-use portion is at least one of degraded, dissolved, broken down, or destroyed to inhibit the operability of at least one operable component of the medical device.

11. The method of claim 10 , wherein sterilization of the medical device above the sterilization threshold renders the medical device mechanically inoperable.

12. The method of claim 10 , wherein sterilization of the medical device above the sterilization threshold renders the medical device electrically inoperable.

13. The method of claim 10 , wherein sterilization includes a chemical sterilization process, and wherein the limited-use portion transitions to the second state due to contact with at least one chemical used in the chemical sterilization process.

14. The method of claim 10 , wherein sterilization includes the use of an autoclave, and wherein the limited-use portion transitions to the second state due to autoclaving.

15. The method of claim 10 , wherein sterilization includes at least one energy-based sterilization process, and wherein the limited-use portion transitions to the second state due to exposure to the at least one energy-based sterilization process.

16. The method of claim 10 , wherein sterilization includes a high temperature sterilization process including a sterilization temperature, and wherein the limited-use portion transitions to the second state at a temperature equal to or below the sterilization temperature.

17. A medical device, comprising:

a handle assembly;

a shaft extending distally from the handle assembly;

an end effector coupled to a distal end of the shaft; and

at least one limited-use portion incorporated into at least one of the handle assembly, the shaft, or the end effector, wherein the limited-use portion is configured to at least one of degrade, dissolve, break down, or destruct during or after the limited-use portion is subjected to sterilization.

18. The medical device according to claim 17 , wherein the limited-use portion is fabricated from at least one of polystyrene, sucrose thermo-plastics, polypropylene, low density polyethylene, ferrous materials, polyoxybenzylmethylenglycolanhydride, or polyvinyl alcohol.
