Percutaneous access and procedures frequently refer to catheter procedures such as percutaneous transluminal angioplasty (PTA) ballooning, stent delivery, filter delivery, cardiac ablation, and peripheral or neurovascular catheter procedures but also refers to a device that is implanted in the body, such as a heart pump (LVAD), and receives ...
Drug delivery systems have been around for many years, but there are a few recent applications of drug delivery that warrant 1. Drug delivery to the brain: Many drugs can be harmful when administered systemically; the brain is very sensitive to medications and can easily cause damage if a drug is administered directly into the bloodstream.
It is sometimes impossible for humane reasons to apply a drug to the skin and measure its absorption. Sarin, a nerve gas, can be absorbed through intact skin and be lethal at low concentrations. Thus if one needs to assess the risk of Sarin exposure one must take skin absorption and other routes into account but one cannot ethically test Sarin ...
A peripherally inserted central catheter (PICC or PICC line), also called a percutaneous indwelling central catheter or longline, [1] is a form of intravenous access that can be used for a prolonged period of time (e.g., for long chemotherapy regimens, extended antibiotic therapy, or total parenteral nutrition) or for administration of substances that should not be done peripherally (e.g ...
Subcutaneous injections can also be used when the increased bioavailability and more rapid effects over oral administration are preferred. They are also the easiest form of parenteral administration of medication to perform by lay people, and are associated with less adverse effects such as pain or infection than other forms of injection.

Administration can take place via enteral administration (absorption of the drug through the gastrointestinal tract) [2] or parenteral administration (generally injection, infusion, or implantation). [3] [4] Contrast with topical administration where the effect is generally local. [4]
For transdermal delivery, drugs must pass through the two sublayers of the epidermis to reach the microcirculation of the dermis. The stratum corneum is the top layer of the skin and varies in thickness from approximately ten to several hundred micrometres, depending on the region of the body. [1]
