Abstract
The present disclosure relates to a medical device and methods of using the same. In embodiments, the medical device may be a buttress formed of nucleophilic buttress components and electrophilic buttress components which react to both form the buttress and provide the buttress with self-sealing capabilities after a staple or some other fixation device is placed therethrough, thereby enhancing its hemostatic properties. In other embodiments, the medical device is a hernia patch formed of a fibrous substrate, nucleophilic precursor components and electrophilic precursor components.
Claims34
A medical device comprising:
- a fibrous substrate;
- and
- a body comprising the reaction product of a nucleophilic precursor component and an electrophilic precursor component;
- wherein the medical device has a thickness from about 0.1 mm to about 3 mm.
A method comprising:
- contacting a fibrous substrate with a nucleophilic precursor component in solution to form a medical device precursor;
- lyophilizing the medical device precursor;
- contacting an electrophilic precursor component with the medical device precursor;
- and
- allowing the nucleophilic precursor component and the electrophilic precursor component to react to form a medical device.
A method comprising:
- contacting a nucleophilic buttress component in solution with an electrophilic buttress component;
- allowing the nucleophilic buttress component to react with the electrophilic buttress component to form a buttress precursor;
- and
- lyophilizing the buttress precursor to form a foam.
