Catheter systems and methods for determining blood flow rates based on temperature measurements by thermodilution. The catheter may include a fluid lumen defined between inner and outer tubular members for delivering an indicator fluid, and a guidewire lumen defined by the inner tubular member. The catheter may include fluid infusion openings at the distal end region of the outer tubular member configured to permit the indicator fluid to exit the catheter from the fluid lumen, and a fluid hole located at the distal end region of the inner tubular member configured to permit the indicator fluid to pass from the fluid lumen into the guidewire lumen. A temperature sensor positioned on a guidewire may be positioned within the guidewire lumen to measure the temperature of the indicator fluid entering the guidewire lumen through the fluid hole. A blood flow rate may be calculated based on the measured temperature.

A stent comprises a plurality of circumferential bands. Circumferential bands which are adjacent one another are connected one to the other. The circumferential bands include peaks and troughs interconnected by bent struts. The bands may overlap or may be connected by connectors.

Stent

A stent comprises a generally cylindrical band having a pattern of alternating first and second struts, the first struts being wider than the second struts, the first and second struts being of substantially the same length.

Flexible stent with improved axial strength

In one embodiment of the invention, a stent may be provided comprising a first undulating band having alternating peaks and troughs, a second undulating band having alternating peaks and troughs, a first substantially longitudinal connector extending between the first and second undulating bands and a second very short connector extending between the first and second undulating bands, the first connector substantially longer than the second very short connector.

Flexible and expandable stent

A stent is provided having attachment members for allowing attachment of a sheath or sheaths. Accordingly, a practitioner is able to selectively choose a desirable sheath, such as a polymeric sleeve, a biomaterial, or a natural blood vessel, at a point-of-use and attach it to the sheath. The attachment members may be bendable tabs and/or secondary support stents.

Stent design with sheath attachment members

An intravascular filter can capture and eliminate emboli. In particular, an intravascular filter may include a plurality of filter legs extending from an apical head. The filter legs may be configured to capture emboli. A drug reservoir that includes or contains a therapeutic drug can be disposed near the apical head. The therapeutic drug, such as a thrombolytic or anti-coagulatory drug, may be eluted in response to a captured emboli.

Intravascular filter with drug reservoir

A stent can include a tubular body, a plurality of circumferential serpentine bands, a plurality of connectors extending between immediately adjacent serpentine bands, and a plurality of tabs. The plurality of tabs include peak tabs and trough tabs. Each peak tab and each trough tab have a first end and a second end wherein only the first end is engaged to a serpentine band, each peak tab extends substantially parallel to the longitudinal axis from a peak on a serpentine band toward a peak on an immediately distal serpentine band. Each trough tab extends substantially parallel to the longitudinal axis from a trough on a serpentine band toward a trough on an immediately proximal serpentine band. Each serpentine band defines a plurality of holes and each tab defines a plurality of holes. The holes are constructed and arranged to contain a therapeutic agent.

Stent with tabs and holes for drug delivery

A bioerodible endoprosthesis erodes to a desirable geometry that can provide, e.g., improved mechanical properties or degradation characteristics.

The present invention is directed to a green fluoropolymer tube which has a wall thickness of about 250 microns or less, preferably about 200 microns or less, and more preferably about 125 microns or less. With such thinness, the green tube may be formed into a tube of expanded fluoropolymer having a wall thickness of about 250 microns or less, preferably about 200 &#x3bc;m or less and more preferably about 125 microns or less. Such an expanded fluoropolymer tube is particularly well-suited for use as an endovascular prosthesis, such as a graft, or in a stent-graft, because of its flexibility and strength.

Green fluoropolymer tube and endovascular prosthesis formed using same

In one embodiment of the invention, a stent may be provided comprising a first undulating band comprising a series of alternating first peaks and first troughs and a second undulating band comprising a series of alternating second peaks and second troughs. The first undulating band has a first wavelength and a first amplitude and the second undulating band has a second wavelength and a second amplitude where the second amplitude is different from the first amplitude and the second wavelength is different from the first wavelength. A plurality of longitudinally oriented first connectors extend between the first peaks and second peaks.
