A system adapted to be disposed between a rigid or semi-rigid device and human skin for reliably attaching the device to the skin for an extended period of time. The system includes a skin-contacting surface for adhering to human skin, and an opposed surface for attachment to a rigid or semi-rigid device. The system is attached along its opposed surface to a portion of the total area of the adjacent surface of the device. When the device is subjected to external stress, the stress is transmitted through the area of attachment and distributed to the unattached area. This minimises stress on the skin and reduces the chance of detachment from the skin.

A catheter system, comprising: a working catheter having a distal working orifice; a guide catheter having a guide lumen and a distal guide orifice; a locking mechanism which locks said working catheter relative to said guide catheter in (i) an operative position, and (ii) a stowed position; and a tissue ingrowth member secured to an outer surface of said guide catheter and configured to facilitate fibrous tissue growth therein, whereby subcutaneous tissue of a body becomes affixed to said tissue ingrowth member when said tissue ingrowth member remains in contact with said subcutaneous tissue over a period of time, wherein when said working catheter is locked in said operative position, (i) said working catheter extends through said guide lumen of said guide catheter and out of said distal guide orifice of said guide catheter, and (ii) said distal working orifice of said working catheter is positioned outside of said guide catheter, wherein when said working catheter is locked in said stowed position, (i) said working catheter extends into said guide lumen of said guide catheter, and (ii) said distal working orifice of said working catheter is positioned within said guide lumen of said guide catheter, further comprising a quantity of blood clot dissolving liquid positioned within said guide lumen of said guide catheter when said working catheter is locked in said stowed position, wherein: said blood clot dissolving liquid contacts said working catheter at said distal working orifice when said working catheter is locked in said stowed position. 6. The catheter system of claim 5, wherein said blood clot dissolving liquid includes urokinase. 7. A catheter system, comprising: a multi-lumen working catheter having a first distal working orifice and a second distal working orifice; a guide catheter having a guide lumen and a distal guide orifice; a locking mechanism which locks said working catheter relative to said guide catheter in (i) an operative position, and (ii) a stowed position; and a tissue ingrowth member secured to an outer surface of said guide catheter and configured to facilitate fibrous tissue growth therein, whereby subcutaneous tissue of a body becomes affixed to said tissue ingrowth member when said tissue ingrowth member remains in contact with said subcutaneous tissue over a period of time, a distal valve configured to inhibit fluid from advancing through said distal guide orifice and into said guide lumen of said guide catheter wherein when said working catheter is locked in said operative position, (i) said working catheter extends through said guide lumen of said guide catheter and out of said distal guide orifice of said guide catheter, and (ii) said first distal working orifice and said second distal working orifice are each positioned outside of said guide catheter, and wherein when said working catheter is locked in said stowed position, (i) said working catheter extends into said guide lumen of said guide catheter, and (ii) said first distal working orifice and said second distal working orifice are each positioned within said guide lumen of said guide catheter. 8. The catheter system of claim 7, wherein: said distal valve is secured to said guide catheter, and said distal valve is positioned within said guide lumen of said guide catheter. 9. A catheter system, comprising: a multi-lumen working catheter having a first distal working orifice and a second distal working orifice; a guide catheter having a guide lumen and a distal guide orifice; a locking mechanism which locks said working catheter relative to said guide catheter in (i) an operative position, and (ii) a stowed position; and a tissue ingrowth member secured to an outer surface of said guide catheter and configured to facilitate fibrous tissue growth therein, whereby subcutane
