Abstract: The anti-back-flow devices and methods prevent fluid from leaking proximally from a catheter, but allow ready access to the catheter using any male luer device. The devices include proximal surfaces that urge open a valve in response to force from a male luer tip. The valves are associated a female luer hub and adapted to function with standard and typical non-standard male luer fittings.

Abstract: A catheter having an elongated shaft and a balloon on a distal shaft section, the elongated shaft comprising an outer tubular member, and an inner tubular member which has a bonded portion along which an outer surface of the inner tubular member is bonded to an inner surface of the outer tubular member. The inner tubular member has a proximal portion proximal to the bonded portion, and a distal portion distal to the bonded portion with higher axial compression stiffness and column strength than the proximal portion thereof. The catheter has improved trackability, axial collapse resistance, pushability, and crossability, for improved ability to position the balloon at a desired location in a patient's body lumen.

Abstract: An automatically locking safety device, e.g., for use in a blood collection procedure, can include a housing, first and second needle covers that are at least partly received in the housing, and a needle that is at least partly received in at least one of the first and second needle covers. The needle can include a proximal tip configured for placement into a patient and a distal tip configured for placement into a blood collection vial. In some embodiments, the first and second needle covers are biased by a biasing member. In some cases, one or both of the first and second needle covers can be locked to prevent axial movement thereof after the blood collection procedure. In certain embodiments, a distal end of the device is configured to connect with a medical connector, such as a needleless IV access device.

Abstract: A device for the neutralization and disposal of unused medicaments, such as drugs or medications. The device generally comprises a means of storing disposal device material, which can render medicaments unusable, and a means of exposing the disposal device material to the medicaments when they are no longer in use. The device may be a medicament container comprising a reservoir to store the disposal device material, and a means to expose the disposal device material to the medicaments. Alternatively, the device may be a medicament closure or lid for use with a medicament container, in which the closure comprises a reservoir for storing the disposal device material and a means to expose the disposal device material to the medicaments.

Abstract: A fluid delivery device includes a cartridge and a syringe. The cartridge includes a housing and a stopper positioned within a fluid chamber defined by the housing. The syringe includes a needle, and an outer body and an inner core which cooperate to receive at least a portion of the housing. When the fluid delivery device is in a first configuration, at least a portion of the cartridge is positioned within the syringe and the stopper is connected to the inner core. In a second configuration, a lumen defined by the needle is in fluid communication with the fluid chamber.

Abstract: A balloon catheter including an elongated shaft having an inflation lumen, a guidewire lumen, a proximal shaft section, and a distal shaft section with a balloon on the distal shaft section, the distal shaft section formed by an outer tubular member having an opening in a sidewall, and an inner tubular member having a distal portion in the outer tubular member and a proximal portion extending through the sidewall opening and along an outer surface of a portion of the outer tubular member located proximal to the sidewall opening, with polymeric filler material around the outer surface of at least the proximal portion of the inner tubular member. The inner tubular member preferably comprises a polymeric tube having a reinforcing coiled member embedded therein. Preferably, a crescent shaped portion of the inflation lumen extends along side the proximal portion of the inner tubular member.

Abstract: An anchor for an implantable medical device, for example, and implantable physiologic sensor, includes a proximal hub portion, an intermediate portion extending radially and distally from the hub portion, and a distal portion extending distally from the proximal portion and adapted to engage an inner surface of a target vessel for securing the implantable medical device therein. The anchor can assume a collapsed configuration for delivery through a catheter, and an expanded configuration for fixation within the vessel once deployed. The intermediate portion extends from the proximal portion at an oblique angle, allowing the anchor to be retracted and re-collapsed within the delivery catheter after initial deployment, if re-positioning or removal of the implantable medical device is necessary or desired.

Abstract: 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.

Abstract: A delivery system for an implantable medical device including a tether retaining feature having a bore. The system includes a connector having a top surface, a bottom surface, a rail extending in a proximal direction from the connector, and an aperture sized to receive the tether retaining feature and reduce movement of the connector with respect to the implantable medical device in a plane parallel to the aperture. A tether is sized to fit within the bore of the tether retaining feature. The tether acts against the top surface of the connector to retain the bottom surface of the connector proximal to the implantable medical device when the tether is located within the bore of the tether retaining feature. A method for delivering an implantable medical device including a tether retaining feature.
