Abstract: An implant delivery system including a catheter having a delivery lumen; a pusher member slidably disposed in the catheter delivery lumen; a retaining member coupled to a distal end portion of the pusher member, the retaining member configured to retain an expandable implant in a collapsed configuration on the pusher member for delivery of the implant through the catheter delivery lumen; and an expandable actuator coupled to the distal end portion of the pusher member and operatively associated with the retaining member, wherein expansion of the actuator causes the retaining member to disengage from an implant carried on the pusher member, to thereby allow the implant to expand from the collapsed configuration.

Abstract: Methods and systems are provided for intra-airway breath sensors where intra-airway breath sensors are not located within a ventilation gas delivery circuit, but are exposed to spontaneous respiration airflow from a patient. Furthermore, methods and systems of the present invention may be used to protect an intra-airway breath sensor from contacting tissue or accumulating debris that may impair abilities of the intra-airway breath sensors.

Abstract: An apparatus for treatment of a bifurcation of a body lumen, the bifurcation having a main vessel and a branch vessel, the apparatus includes a bifurcated balloon with a first branch portion and a second branch portion, the second branch portion including an inflatable portion adapted to extend toward the branch vessel, the bifurcated balloon also having a proximal shaft portion and a distal shaft portion connected to the inflatable portion of the second branch portion, and wherein the first branch portion and the second branch portion each have a longitudinal axis, the axis of the first branch portion being substantially parallel to the longitudinal axis of the second branch portion.

Abstract: A stent delivery system includes an elongate delivery member; a self-expanding proximal bumper disposed on a distal region of the delivery member in a radially contracted configuration, where the proximal bumper is biased to expand to a radially expanded configuration; a self-expanding stent disposed over the delivery member in a radially contracted configuration distal of the proximal bumper; and a sheath disposed over the stent, proximal bumper, and delivery member, and configured to constrain the proximal bumper and stent in their radially contracted configurations, where the proximal bumper, when in its radially expanded configuration, has a cross-sectional dimension greater than an inner diameter of the sheath, such that the proximal bumper contacts the sheath and prevents movement of the stent proximal of the proximal bumper, and such that, as the delivery member is moved distally relative to the sheath, the proximal bumper pushes the stent in a distal direction.

Abstract: Modes, methods, systems and devices are described for providing assisted ventilation to a patient, including wearable ventilation systems with integral gas supplies, special gas supply features, ventilation catheters and access devices, and breath sensing techniques.

Abstract: A system for treatment of a bifurcation of a body lumen, the bifurcation having a main vessel and a branch vessel, the system includes a catheter having a main catheter shaft and a first balloon associated with the main catheter shaft, a side sheath and a second balloon associated with the side sheath, and a stent including a generally cylindrical body and a branch portion. A method is also described which includes advancing a catheter system through the main vessel, positioning a branch portion of a stent present in the system proximate to a branch vessel, and inflating first and second balloons thereby expanding a main body and branch portion of the stent.
