System of surgical staple cartridges comprising absorbable staples
Staple cartridges including bioabsorbable staples are disclosed. The staples are configured such that they are bioabsorbable within a desired time frame.
1 . A staple cartridge, comprising:
a deck;
an elongate slot;
staple cavities defined in said deck; and
staples positioned in said staple cavities, wherein said staples are configured to be deployed into a tissue environment, wherein said staples are comprised of a magnesium-based alloy, and wherein said magnesium-based alloy is selected such that said staples bio-corrode in said tissue environment within a predetermined bio-corrosion timeframe,
wherein said staples comprise a coating, the coating configured to tune a rate of bio-corrosion of the staples to meet the predetermined bio-corrosion timeframe based on a mechanism of action, by balancing an increase of the rate of bio-corrosion caused by the magnesium-based alloy and a decrease of the rate of bio-corrosion caused by a calcification.
2 . The staple cartridge of claim 1 , wherein said coating is applied at manufacture.
3 . The staple cartridge of claim 1 , wherein said staples are configured to be coated after said staples have been deployed into the tissue environment.
4 . The staple cartridge of claim 1 , wherein said coating is further configured to trap ions.
5 . The staple cartridge of claim 1 , wherein said coating is further configured to inhibit onset of oxidation.
6 . The staple cartridge of claim 1 , wherein said coating is further configured to divert deposition therefrom.
7 . The staple cartridge of claim 1 , wherein said coating is further configured to capture deposition thereon.
8 . The staple cartridge of claim 1 , wherein said mechanism of action comprises at least one of oxidation, hydrolysis, galvanic corrosion, a replacement reaction between magnesium and hydrochloric acid, or stress corrosion, and tuning the rate of bio-corrosion comprising at least one of increase, decease, or reserve the rate of bio-corrosion of the staples.
9 . A staple cartridge, comprising:
a deck;
an elongate slot;
staple cavities defined in said deck; and
staples positioned in said staple cavities, wherein said staples are configured to be deployed into a tissue environment, wherein said staples are comprised of a zinc-based alloy, and wherein said zinc-based alloy is selected such that said staples bio-corrode in said tissue environment within a predetermined bio-corrosion timeframe,
wherein said staples comprise a coating, the coating configured to tune a rate of bio-corrosion of the staples to meet the predetermined bio-corrosion timeframe based on a mechanism of action, by balancing an increase of the rate of bio-corrosion caused by the zinc-based alloy and a decrease of the rate of bio-corrosion caused by a calcification.
10 . The staple cartridge of claim 9 , wherein said coating is applied at manufacture.
11 . The staple cartridge of claim 9 , wherein said staples are configured to be coated after said staples have been deployed into the tissue environment.
12 . The staple cartridge of claim 9 , wherein said coating is further configured to trap ions.
13 . The staple cartridge of claim 9 , wherein said coating is further configured to inhibit onset of oxidation.
14 . The staple cartridge of claim 9 , wherein said coating is further configured to divert deposition therefrom.
15 . The staple cartridge of claim 9 , wherein said coating is further configured to capture deposition thereon.
16 . The staple cartridge of claim 9 , wherein said mechanism of action comprises at least one of oxidation, hydrolysis, galvanic corrosion, a replacement reaction between magnesium and hydrochloric acid, or stress corrosion, and tuning the rate of bio-corrosion comprising at least one of increase, decease, or reserve the rate of bio-corrosion of the staples.
17 . A staple cartridge, comprising:
a deck;
an elongate slot;
staple cavities defined in said deck; and
staples positioned in said staple cavities, wherein said staples are configured to be deployed into a tissue environment, wherein said staples are comprised of an iron-based alloy, and wherein said iron-based alloy is selected such that said staples bio-corrode in said tissue environment within a predetermined bio-corrosion timeframe,
wherein said staples comprise a coating, the coating configured to tune a rate of bio-corrosion of the staples to meet the predetermined bio-corrosion timeframe based on a mechanism of action, by balancing an increase of the rate of bio-corrosion caused by the iron-based alloy and a decrease of the rate of bio-corrosion caused by a calcification.
18 . The staple cartridge of claim 17 , wherein said coating is applied at manufacture.
19 . The staple cartridge of claim 17 , wherein said staples are configured to be coated after said staples have been deployed into the tissue environment.
20 . The staple cartridge of claim 17 , wherein said coating is further configured to trap ions.
21 . The staple cartridge of claim 17 , wherein said coating is further configured to inhibit onset of oxidation.
22 . The staple cartridge of claim 17 , wherein said coating is further configured to divert deposition therefrom.
23 . The staple cartridge of claim 17 , wherein said coating is further configured to capture deposition thereon.
24 . The staple cartridge of claim 17 , wherein said mechanism of action comprises at least one of oxidation, hydrolysis, galvanic corrosion, a replacement reaction between magnesium and hydrochloric acid, or stress corrosion, and tuning the rate of bio-corrosion comprising at least one of increase, decease, or reserve the rate of bio-corrosion of the staples.
