摘要： A method for manufacturing a medical introducer includes placing an introducer sheath onto a mandrel, and overmolding an introducer hub onto a proximal end of the introducer sheath. The introducer sheath has one or more score lines formed on an inner surface and the mandrel has a number of surface protrusions so that when the introducer sheath is positioned on the mandrel, each of the surface protrusions contacts one of the score lines formed on the introducer sheath. The surface protrusions on the mandrel prevent plastic material from the introducer hub from contacting the score lines thereby maintaining the score lines during the overmolding.

摘要： A method for manufacturing an implantable lead includes forming an elongated lead body core that defines a longitudinal axis. The elongated lead body core has a plurality of axially extending channels that are circumferentially spaced apart from one another around the elongated lead body core. The method also includes positioning an electrode ring around the elongated lead body core and electrical conductors. The method includes positioning a respective electrical conductor in each of the axially extending channels and positioning a dielectric insulator ring around the elongated lead body core and electrical conductors.

摘要： A steerable intravascular catheter includes a handle assembly having opposed proximal and distal end portions and defining a longitudinal axis therebetween. An elongated sheath extending from the distal end portion of the handle assembly has opposed proximal and distal end portions, and includes a tubular body wall forming a central lumen for accommodating the introduction of a device and a fluid lumen radially outward from and parallel to the central lumen. The distal end portion of the elongated sheath is deflectable relative to the proximal end portion of the elongated sheath. A rotatable actuation assembly is associated with the handle assembly for controlling deflection of the distal end portion of the elongated sheath. An inflatable occlusion balloon is positioned on an outer surface of the distal end portion of the elongated sheath. The fluid lumen of the elongated sheath is in fluid communication with an interior of the balloon.

摘要： A vascular introducer system includes a first vascular introducer having an elongated first deflectable catheter sheath defining a lumen having an interior surface with an inner diameter. A tubular insert having a polygonal cross-section is associated with the interior lumen of the first catheter sheath. The system includes a second vascular introducer having an elongated second deflectable catheter sheath defining an exterior surface with an outer diameter that is less than the inner diameter of the interior surface of the first catheter sheath.

摘要： A radial artery compression band is disclosed for circumferential placement around the wrist of a patient to apply hemostasis pressure to a wound, which includes a first arcuate band portion including a radially outwardly extending support frame, a second elongated band portion including a plurality of longitudinally spaced apart radially outwardly extending ramped engagement teeth, a third elongated band portion extending between the first and second band portions and including a radially inwardly facing compression structure for applying hemostasis pressure to the wound, and a band adjustment mechanism mounted within the support frame of the first arcuate band portion and including an axially rotatable shaft having a worm gear section with a continuous helical thread for selectively intermeshing with the ramped engagement teeth on the second elongated band portion to adjust band tension through axial rotation of the shaft.

摘要： A steerable intravascular catheter is disclosed which includes an elongated sheath having a tubular body wall defining a central lumen and a deflectable distal end portion, a pair of laterally opposed elongated pull wires extending through the tubular body wall of the sheath and terminating within the distal end portion thereof, and a handle assembly having a longitudinal axis and operatively associated with a proximal end portion of the sheath, the handle assembly including an rotatable control knob for controlling bi-directional deflection of the distal end portion of the sheath, wherein bi-directional angular rotation of the control knob about the longitudinal axis of the handle assembly effectuates corresponding reciprocal axial movement of the laterally opposed pull wires in opposed axial directions and corresponding bi-directional deflection of the distal end portion of the sheath.

摘要： A hemostasis valve for a vascular introducer includes a valve body having a seal region with opposed substantially planar proximal and distal end surfaces and a central axis extending through the seal region perpendicular to the proximal and distal end surfaces. The seal region has a first grouping of circumferentially arranged and equidistantly spaced linear cuts extending radially outward from the central axis, and through the seal region from the proximal end surface to the distal end surface. The seal region has a second grouping of circumferentially arranged and equidistantly spaced linear cuts in the distal end surface extending tangentially outward from the first grouping of linear cuts, and partially from the distal end surface to a depth short of the proximal end surface to facilitate passage of a variety of sizes of medical devices through the seal region.
