The present embodiments relate generally to systems and methods for measuring an analyte in a host. More particularly, the present embodiments provide sensor applicators and methods of use with activation that implant the sensor, withdraw the insertion needle, engage the transmitter with the housing, and disengage the applicator from the housing. Systems and methods according to present principles allow for such steps to occur without significant loss of spring force, and without deleterious effects such as seal slingshotting.

Transcutaneous analyte sensors, applicators therefor, and associated methods

Balloon catheter includes an elongate tubular shaft having an outer tubular member having proximal and distal portions, and an inner tubular member having a distal length extending distally from the distal portion of the outer tubular member. The elongate tubular shaft has an inflation lumen and a guidewire lumen defined therein. The guidewire lumen extends along at least the distal length of inner tubular member. The balloon catheter also includes a distal end section coupled to a distal end of the inner tubular member and having a proximal end and a distal end. The balloon catheter also includes a balloon having a proximal portion sealingly coupled to the distal portion of the outer tubular member, a distal portion sealingly coupled to the distal end section, and a working length therebetween. The balloon defines an inner chamber. The proximal end of the distal end section is disposed within the inner chamber.

Catheter having transitioning shaft segments

A catheter having shaft segments which are joined together by a strong bond providing a low profile shaft section with a flexibility transition and/or a compositional transition. A balloon catheter embodying features of the invention has a distal tip member and a coupling band member surrounding a junction of an inner tubular member of the shaft, and has a gradual change in bending stiffness along a distal end section of the shaft which extends distally from a location within the balloon interior. Another catheter embodying features of the invention has shaft segments joined together by a diagonal seam.

An improved stent design and stent delivery catheter assembly for repairing a main vessel and a side branch vessel forming a bifurcation. The stent includes rings aligned along a common longitudinal axis and connected by links, where the stent has one or more portals for aligning with and partially expanding into the opening to the side branch vessel. The stent is implanted at a bifurcation so that the main stent section is in the main vessel, and the portal section covers at least a portion of the opening to the side branch vessel. A second stent can be implanted in the side branch vessel and abut the expanded central section to provide full coverage of the bifurcated area in the main vessel and the side branch vessel. Radiopaque markers on the stent and on the tip of the delivery catheter assist in aligning the portal section with the opening to the side branch vessel.

The invention is directed to a catheter system having an ultrasonic delivery device, a dilatation balloon, and a stent. The ultrasonic distal head is used to ablate a lesion permitting the dilation balloon to cross the lesion for dilatation and for delivering the stent to the lesion. A catheter body includes a first lumen for dilatation balloon expansion control fluid, and a second lumen for the guide wire. The ultrasonic distal head includes a guide wire aperture large enough to permit complete retraction of the guide wire so that the guide wire may be replaced with another while the catheter remains in place within the vasculature of the patient.
