    摘要: A modular stent graft system and associated surgical methods are provided that incorporates an external stent-based locking mechanism to prevent disarticulation of the legs from the bifurcated graft as well as other features that overcome many of the difficulties of the prior art associated with delivering and securing the bifurcated grafts to the intended deployment site within the human aorta.

    摘要: A safety catheter for draining a given fluid includes a hollow stretch valve and a flexible, multi-lumen, balloon drainage catheter having a proximal catheter end, a balloon defining a balloon interior to be inflated with an inflation fluid, a drain lumen. and a balloon drainage port fluidically connecting the balloon interior to the drain lumen. The hollow stretch valve is shaped to permit the given fluid to pass therethrough and is positioned in the drain lumen to at least partially slide therein such that, in a steady state, the stretch valve prevents the inflation fluid from passing through the drainage port, and, in a stretched state when the proximal catheter end is stretched, the distal sliding portion slides within the drain lumen to permit the inflation fluid to pass through the drainage port and into the drain lumen.

    摘要: A safety catheter includes a flexible, multi-lumen shaft having an outer diameter, a distal tip, a proximal catheter end with a drain end and a proximal inflation end. The multi-lumen shaft defines a drain lumen, a distal hollow balloon portion, at least one inflation lumen, and a drainage port. A hollow stretch valve is coaxially disposed in the drainage lumen and has a radially self-expandable proximal section fixedly connected within the drain lumen by self-expansion, a flexible intermediate section longitudinally movable within the drain lumen, and a distal plug movably positioned in the drain lumen to prevent fluid from passing through the drainage port in a steady state and being slidably disposed within the drain lumen such that, in a stretched state when the proximal catheter end is stretched, the distal plug slides within the drain lumen to permit the inflation fluid to pass through the drainage port.

    摘要: A surgical kit includes at least one instrument and at least one implant device. The instrument has a needle body used to form a surgical passage through ocular tissue. The device includes a flexible tube that defines a duct for diverting aqueous humor with an outer surface having a maximal cross-sectional dimension that is less than the maximal cross-sectional dimension of the needle body. The device incorporates sealing means including at least one element that define a maximal cross-sectional dimension that is greater that the maximal cross-sectional dimension of the needle body and that are operably disposed within the surgical passage and form a seal between the surrounding ocular tissue and the element(s) as well as fixate the device in the surgical passage. The kit (and devices thereof) can be used as part of a surgical method to divert aqueous humor to a space formed in ocular tissue.

    摘要: An improved pacemaker lead including a lead body supporting at least one flexible conductor element that provides an electrical signal path between a proximal connector element and a distal electrode. The lead body includes an insulating structure that protects the flexible conductor element(s) wherein the insulating structure is realized from a polymer blend of a thermoplastic polyurethane elastomer and an isobutylene block copolymer. The mole fraction of the isobutylene block copolymer of the polymer blend is in the range of 2-15% (most preferably on the order of 10%). The polymer blend of the insulating structure has a maximum tensile strength in the range of 20-40 MPa (most preferably in a range of 25-35 MPa). In the preferred embodiment, the hardness of the polymer blend can be characterized by a Shore hardness in a range of 70-80 A. The flexible conductor element(s) preferably include a coiled wire conductor defining a central axis with an outer surface facing radially outward away from the central axis and an inner surface facing radially inward toward the central axis, and the insulating structure surrounds at least the outer surface of the coiled wire conductor (and more preferably encapsulates the coiled wire conductor). The polymer blend of the insulating structure has reduced oxygen permeability, and thus provides improved resistance to environmental stress cracking and metal ion induced oxidation while maintaining the flexibility and desired tensile strength of the lead body.
