Abstract: A surgically implantable reservoir is provided for implantation into a patient for use in an iontophoresis system for local drug delivery through a target site of internal body tissue. The reservoir comprises a housing having an inner surface defining an enclosed chamber and an inlet opening and an outlet opening for flow of fluid including the drug through the chamber. The housing is capable of interacting with a localized electric field to release the drug. A platform holding an electrode extends inwardly into the chamber from the inner surface of the housing such that the platform and an adjacent portion of the inner surface of the housing define a trough surrounding the platform. Fluid flow through the reservoir from the inlet opening to the outlet opening moves gas bubbles formed by electrolysis from the surface of the electrode and carries the bubbles through the outlet opening.

Abstract: An improved splittable medical device introducer designed to introduce a medical device such as a lead or catheter, into a patient's vasculature without loss of blood or introduction of air is described. The introducer assembly is designed with a notch provided at the proximal end of the introducer housing. The notch, which may comprise a multitude of cross-sectional geometries, is designed to reduce the force required to separate the housing and the introducer sheath, thereby minimizing the possibility of unintentional dislodgement during separation. The notch also increases the repeatability and consistency of the amount of force required to separate the introducer housing and sheath.

Abstract: In various examples, an apparatus includes a needle assembly including an outer cannula including a tubular sidewall disposed around a lumen. At least a portion of the sidewall includes an exterior including a polymeric material configured to inhibit skiving of an interior of a dilator with movement of the outer cannula within the dilator. An inner cannula is disposed within the lumen and is selectively slidable with respect to the outer cannula. A handle is disposed at a proximal portion of the needle assembly. The handle includes a first handle portion coupled to and movable with the outer cannula. A second handle portion is coupled to and movable with the inner cannula, wherein the first handle portion is selectively movable with respect to the second handle portion to extend a distal end of the inner cannula from within the lumen of the outer cannula.

Abstract: A medical device including a catheter having a first component having a first color and a wall thickness and a second component having a second color different from the first color and a wall thickness. The first component and the second component are joined by a lap weld having a wall thickness such that the wall thickness of the lap weld is greater than the first component wall thickness and also greater than the second component wall thickness. The first component wall thickness is spaced apart from the lap weld and the second component wall thickness is spaced apart from the lap weld. The first component is disposed over the second component and the first color is selected from the group consisting of blue, green, orange, yellow, or purple.
