Endoscope connector device
The connector device includes a metal internal member, a metal light guide rod and metal fixing bases and, which are connected to the internal member, a resin sheathing member that accommodates the internal member and includes leading-out holes, which lead the light guide rod and the fixing base to the outside, and fluoro rubber O-rings, which are provided on the light guide rod and the fixing bases, the O-rings being respectively placed in gaps between the light guide rod and the fixing bases and the leading-out holes and sealing the inside of the sheathing member.
Polyisoprene latex graphene composites and methods of making them
The present invention relates to a method of preparing reduced graphene oxide, incorporation of the reduced graphene oxide into polyisoprene latex to provide a polyisoprene latex graphene composite and elastomeric articles prepared using the polyisoprene latex-graphene composite. In particular, the reduction of graphene oxide is accomplished without the use of strong reducing agents and organic solvents and incorporation of the reduced graphene oxide into polyisoprene latex is accomplished using room temperature latex mixing method or hot maturation. The resultant composite exhibits good colloid stability and polyisoprene latex films produced from the composite exhibit good mechanical properties with improved ageing resistance.

Drug Device Electroporation Angioplasty System
Active Energy Facilitated Drug Delivery platform for delivering therapeutics to biological tissue through electrical conductivity. This delivery method is comprised of an elastic alloy to encase a balloon or drug deposition, where the alloy acts to emit an electric field in aiding and actively allowing the pharmaceutical agent to have enhanced permeation, binding and internalization to cells and the biological matrix. A therapeutic agent is deposited onto a balloon to embody the drug deposition, reservoir whereby the electrical field facilitates the active transfer of a pharmaceutical agent to the target tissue is described.

Integrated Thrombectomy and Filter Device and Methods of Use
The invention relates generally to methods and systems for capturing, filtering, or retrieving obstructions or other particulates from a patient's vasculature. It may relate to integrated thrombectomy and filtering devices and methods of use. The methods and systems may be configured to remove obstructions such as clots or foreign body objects from a neurovascular vessel or other vasculature and/or provide protection from distal emboli. In one aspect, device for retrieving an obstruction from a patient is provided that includes an outer delivery shaft and an expandable basket movable between a collapsed configuration and an expanded configuration. The basket is configured to be in the collapsed configuration during delivery and in the expanded configuration during engagement and retrieval of the obstruction. A proximal end of the basket is configured to be centrally and pivotally coupled to the outer delivery shaft. The proximal end and/or a distal end of the basket is movable relative to each other such that a proximal portion of the expandable basket is invertible toward a distal portion of the basket to form a proximally oriented cavity in the expanded configuration to engage and retrieve the obstruction.
