Dispensing catheter and method

A method for delivering a medical material of the body of a living being comprising:

• (a) forming a select quantity of medical treatment material,
• (b) disposing a select amount of said medical material in a small container formed with a wall portion thereof made at least partly of a bio-degradeable material which degrades upon contact with body fluid in a manner to release said medical treatment material from said container,
• (c) disposing said small container with a quantity of adhesive secured thereto in the operating head of a dispensing catheter and inserting said catheter into a body duct of a living being,
• (d) working said catheter through said body duct to dispose said operating head in alignment with select body tissue,
• (e) expelling said small container from said operating head to cause it to contact select tissue within the body and to cause said adhesive to bond said container to the tissue it contacts,
• (f) removing said catheter from the body duct,
• (g) allowing body fluid to react on said biodegradeable material of said container while it is adhesively bonded to said tissue in a manner to cause said medical material to become released from said container and to be dispensed therefrom into the body of said living being.

A method for delivering a medical material to the body of a living being comprising:

• (a) forming a select quantity of medical treatment material,
• (b) encapsulating said medical material in a plurality of microcapsules formed of bio-degradeable material which degrades upon contact with body fluid in a manner to release said medical material from said microcapsules,
• (c) forming a drug dose defined by a select amount of said microcapsules with an adhesive,
• (d) disposing said drug dose in the operating head of a dispensing catheter,
• (e) inserting said catheter into the body of a living being and disposing the operating head thereof in alignment with select tissue of said living being,
• (f) expelling a select amount of said mixture of microcapsules and adhesive to cause same to contact and become adhesively bonded to said select tissue in the presence of body fluid,
• (g) allowing said body fluid to degrade said microcapsules to permit the medical material contained thereby to be slowly released therefrom.
