Methods and compositions for treating post-cardial infarction damage

摘要

Methods and compositions for treating post-myocardial infarction damage are herein disclosed. In some embodiments, a carrier with a treatment agent may be fabricated. The carrier can be formulated from a bioerodable, sustained-release substance. The resultant loaded carrier may then be suspended in at least one component of a two-component matrix system for simultaneous delivery to a post-myocardial infarction treatment area.

1. A needle catheter device comprising:
a first delivery needle having a first outer surface around a first lumen; a second delivery needle having a second outer surface around a second lumen, wherein the second delivery needle is side-by-side with the first delivery needle such that the second outer surface is outside of the first lumen, and the second lumen does not coincide with and is laterally offset from the first lumen; and a biasing element having a first end coupled to the first outer surface and a second end coupled to the second outer surface.
