Methods, devices, and systems for a) revascularization and/or b) performing other medical procedures at vascular or non-vascular intracorporeal locations within a mammalian body. The methods generally comprise the formation of at least one extravascular passageway from a blood vessel to a vascular or non-vascular target location. In the revascularization methods the extravascular passageway is utilized for blood flow. In the medical procedure methods the extravascular passageway is utilized as a conduit for accessing or performing procedures at the vascular or non-vascular target location. Also disclosed are catheter devices and systems which are useable to form the extravascular passageways of the invention, as well as apparatus for modifying, maintaining and/or closing such extravascular passageways.

An intraluminal prosthesis is provided with a plurality of annular elements. Each annular element includes a plurality of struts and apices connected to form an annular configuration. Each annular element has a compressed state and an expanded state, and has a longitudinal dimension which is smaller in the expanded state than in the compressed state. A plurality of connecting members connect the apices of adjacent annular elements. The connecting members have a plurality of alternating segments that function to compensate for the smaller longitudinal dimension of each annular element in the expanded state. The stent may be provided with varying flexibility along its length and/or circumference, and may include segments that have different diameters.

摘要:
An implantable fluid delivery device for dispensing metered aliquots of liquid medication upon finger-pressure activation of the device by a patient. The device includes a soft, deformable needle-piercable casing having a fluid reservoir in which is located a relatively-rigid, apertured support plate that divides the reservoir into upper and lower chambers. A compressible, positive displacement pump chamber or housing is mounted upon the plate within the upper chamber and includes passages communicating with both the lower chamber and an outlet port. Force applied to a central target zone of the top wall causes compression of the pump housing and delivery through the outlet port of an amount of fluid equal to the displacement of the pump housing. The same target zone of the top wall serves as a self-sealing injection site for replenishing the fluid supply of the reservoir. A rigid, protective needle guard is disposed within the upper chamber above the pump housing to shield that housing against contact by an injection needle when the fluid supply is being replenished. The rigid plate that supports the pump housing also distributes applied pumping forces and provides a platform for supporting other elements of the device, including a fluid filter and surge protector located in the lower chamber of the reservoir at the inlet to the pump housing.
