Method for cleaning and lubricating an angiographic wire with fluid solvent delivery
11759287 · 2023-09-19 ·

A method of guiding an angiographic wire while delivering fluid solvent to the wire. The method incorporates a guide device comprising a housing that is mated to a base in a manner that defines an aperture for slidably receiving the angiographic wire. A plunger is disposed within the housing in a vertically adjustable manner such that the plunger has an open position, a closed position, and one or more intermediate positions relative to the housing. The angiographic wire is placed in the aperture, and the housing is mated to the base such that the wire is slidably retained in the aperture. The plunger is depressed such that a compression pad on the plunger is placed in contact with the wire, the wire being slidably retained between the compression pad and a base pad attached to the base.

Catheter

The present invention relates to a catheter 10. The catheter 10 includes a catheter tube 12 having a tip end 13 and a distal end 14, with the distal end 14 being coupled to or forming at least part of a funnel 16 for discharging fluid from within the catheter tube 12. A sleeve 18 is provided about the catheter tube 12 which is coupled at an end thereof to the funnel 16 and extends towards the tip end 13 of the catheter tube 12. The catheter 10 additionally includes a wetting mechanism 20 which is integrally formed with the funnel 16 and includes a holding chamber 22 and a fluid outlet 26 operable to allow fluid 24 from within the holding chamber 22 to be released within the sleeve 18 for wetting an outer surface of the catheter tube 12.

Wetting Mechanism For A Catheter

The invention relates to a wetting mechanism 20 for wetting a tube 12 of a catheter 10. The wetting mechanism 20 includes a housing 16 positioned initially at or proximal to the tip end 13 of the catheter tube 12. The housing 16 comprises a wetting chamber 23 into which at least a portion of the catheter tube 12 is able to be introduced and be moved therethrough to wet the catheter tube 12 in use. The wetting mechanism 20 includes a stopper 26 which is moveable between a first and second positions to prevent or allow the tip end 13 of the catheter tube 12 to be moved through the wetting chamber 23.

The wetting mechanism 20 comprises a fluid release control component 26 for controlling release of fluid within the holding chamber 22 into the wetting chamber 23. At least a portion of the catheter tube 12 is then able to be introduced and be moved through the wetting chamber 23 to wet the catheter tube 12, in use.

Flush enhancing male luer tip design for syringes and any luer connector

A luer connection device is disclosed having a housing including a side wall having an inside surface defining a lumen with a central axis, an proximal end, and a distal end including a male luer tip within the lumen having a central flow diverter extending outwardly from the central axis to direct a fluid to a circumferential dead space distal to the male luer tip. A luer connection device is also disclosed having a flow expansion channel disposed in the lumen tapering outward from the wall of tubular housing and partially extending along a longitudinal axis from the tip opening toward the base opening for increasing mixing and flow through a circumferential dead space in the fluid path distal to the male luer tip.

A catheter assembly for delivering a medical implant may include an inner shaft around which a compartment is defined, the compartment being adapted to receive the medical implant therein. The catheter assembly may include an outer shaft coaxially surrounding at least a portion of the inner shaft and movable in longitudinal directions relative to the inner shaft. The outer shaft may define a lumen therein, the inner shaft and the outer shaft together defining a space therebetween, the space providing liquid communication between a proximal end of the catheter assembly and the compartment. The catheter assembly may include a distal sheath fixedly connected to the outer shaft, the distal sheath being movable between a closed condition covering the compartment and an open condition uncovering the compartment for deployment of the medical implant. A lubricant containing albumin may be disposed within at least a portion of the space.

ANTI-CLOGGING AND ANTI-ADHESIVE MICRO-CAPILLARY NEEDLE WITH ENHANCED TIP VISIBILITY
20230248953 · 2023-08-10 ·

An object of the present invention is to provide an anti-adhesive/anti-clogging and/or color marked/tinted micro-capillary tube (microtube), microneedle, or micropipette. Typically, the color/tint will be selected such that the tip of the microneedle or micropipette is in contrast (e.g., visually) to the biological material. The tint/color may be selected to contrast the stained biological material. In some aspects, the color mark comprises nanoparticles that are modified by adding a non-adhesive coating/material that minimizes protein adhesion/adsorption. The microtubes and/or micropipettes may be treated with an anti-clogging reagent and an anti-adhesive reagent to prevent or reduce clogging and adhesion of the micropipette or microneedle to biological materials. The microtubes and/or micropipettes may be formed using additive printing processes and additive manufacturing techniques or from micropipette and microneedle pullers.

Medical hollow tube

A cable includes a sheath, and a coating film covering a circumference of the sheath. The coating film adheres to the sheath. The static friction coefficient of a surface of the coating film is smaller than the static friction coefficient of a surface of the sheath. The adhesion strength between the sheath and the coating film is 0.30 MPa or more.
