Abstract

Official abstract text for this publication.

Staple cartridges including bioabsorbable staples are disclosed. The staples are configured such that they are bioabsorbable within a desired time frame.

First claim

Opening claim text (preview).

What is claimed is: 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.
