Abstract
A flexible medical device which is intended to be disposed in the opening or the incision in the skin tissue of an animal includes a thin, flexible, adherent film coating of a bioactive ceramic material at least at a point where the flexible portion of the medical device exits from the tissue. This bioactive coating bonds with the skin at the exit site to prevent infection of the tissue while allowing the catheter to remain flexible.
Claims23
A medical device having a section for insertion into and protrusion from an attachment site, surrounded by tissue, in a body of an animal, said section comprising
- a flexible member having an outer periphery;
- and
- a continuous, bioactive, biocompatible, flexible ceramic coating surrounding and adhered to at least a portion of said outer periphery of said flexible member, said coating having the ability to support growth of said tissue therealong and the ability to form a tight and sterile bond with said tissue, said flexible coating being sufficiently flexible so that said flexible member, when inserted into and protruding from said attachment site, does not significantly restrict movement of the body around said attachment site.
A catheter having a section for insertion into and protrusion from an attachment site, surrounded by tissue, in a body of an animal, said section comprising:
- a flexible member having an outer periphery;
- and
- a continuous, bioactive, biocompatible flexible ceramic coating surrounding and adhered to at least a portion of said outer periphery of said flexible member, said coating having the ability to support growth of said tissue therealong and the ability to form a tight and sterile bond with said tissue, said flexible coating being sufficiently flexible so that said flexible member, when inserted into and protruding from said attachment site, does not significantly restrict movement of the body around said attachment site.
An indwelling catheter, in situ, which extends into a body of a mammal having skin through an attachment site, surrounded by tissue, in said mammal's skin, said catheter comprising:
- a flexible member having an outer periphery and a continuous, bioactive, biocompatible, flexible ceramic coating surrounding and adhered to said outer periphery of said flexible member at a portion of said catheter that contacts said skin at said attachment site, said coating having the ability to support growth of said tissue therealong and the ability to form a tight and sterile bond with said tissue, said flexible coating being sufficiently flexible so that said flexible member does not significantly restrict movement of the body around said attachment site.
A method of catheterizing a mammal, comprising the steps of:
- inserting through an attachment site, surrounded by tissue, in a body of a mammal, a catheter including:
- a flexible member having an outer periphery;
- and
- a continuous, bioactive, biocompatible, flexible ceramic coating surrounding and adhered to at least a portion of said outer periphery of said flexible member, said coating having the ability to support growth of said tissue therealong and the ability to form a tight and sterile bond with said tissue, said flexible coating being sufficiently flexible so that said flexible member does not significantly restrict movement of the body around said attachment site.
A medical device having a section for insertion into and protrusion from an attachment site, surrounded by tissue, in a body of an animal, said section comprising:
- a flexible member having an outer periphery;
- and
- a continuous, bioactive, biocompatible, flexible ceramic coating adhered to at least a portion of said outer periphery of said flexible member, said coating having the ability to support growth of said tissue therealong and the ability to form a tight and sterile bond with said tissue, said flexible coating being sufficiently flexible so that said coated portion, when bound to said tissue surrounding said attachment site, does not significantly restrict movement of the body around said attachment site.
