Medical device bending tool
11577048 · 2023-02-14 · ·

A method and system of bending medical device components for customization to a particular medical procedure and patient while generally maintaining the ideal performance of the component. A medical professional embeds the medical device component into a bending tool. The medical professional then aligns an intended curve region of the medical device component within a bending region of the bending tool and imparts a curve in the bending region. Finally, the medical professional withdraws the medical device component from the bending tool, and utilizes the bent medical device component in the medical procedure. The system may be a kit comprising various medical device components for a particular medical procedure and a suitable bending tool for those components.

Multi-lumen catheter with enhanced flow features

A catheter assembly including a reinforcement structure and a catheter disposed over the reinforcement structure. The reinforcement structure includes a first outer wall reinforcement portion, a second outer wall reinforcement portion, and a septum reinforcement portion connecting the first outer wall reinforcement portion to the second outer wall reinforcement portion. The catheter includes a catheter outer wall and a catheter septum. The first outer wall reinforcement portion and the second outer wall reinforcement portion can be positioned at least partially in the catheter outer wall, and the septum reinforcement portion can be enveloped by the catheter septum. The catheter assembly can also include an outer tube disposed over the catheter and the reinforcement structure.

URINARY CATHETER WITH VARYING PROPERTIES
20180001055 · 2018-01-04 ·

A urinary catheter and a method of its manufacture are disclosed. The urinary catheter comprises a tubular shaft extending between an insertion end and a discharge end, the tubular shaft being formed of at least two materials having different properties. The materials are arranged substantially separated from each other in distinct zones, wherein at least one of the width and thickness of said zones varies over the length of the tubular shaft, to form two or more uniform sections of the tubular shaft having various relative amounts of said materials, and wherein at least one transition between two such uniform sections is formed by at least one transition section providing a gradual transition between the uniform sections. The catheter can e.g. be produced by intermittent extrusion.

MEDICAL DEVICE INSPECTION SYSTEM

A medical device inspection system may include a base, a medical device holder on the base, a fiber scope holder on the base, a moveable roller moveably attached to the base such that it is free to rotate around an axis and move from a first position to a second position along the base, and a feeder coupled with the base for feeding a flexible portion of the fiber scope into a lumen of the medical device. During use, the flexible portion of the fiber scope may extend from the handle, around the moveable roller, and through the feeder to enter an opening in the lumen of the medical device.

Apparatus and Method for Tipping Rapidly Insertable Central Catheters (RICC)
20230233796 · 2023-07-27 ·

A Rapidly Insertable Central Catheter (“RICC”) includes an access section formed of a first material, a catheter body section formed of a second material, and a dilator section disposed therebetween. The first material has a first durometer and the second material has a second, lesser durometer. The dilator section is formed of the first material, the second material, or a third material having a third durometer. The catheter body defines a primary lumen communicating with a primary lumen aperture disposed in a distal tip of the access section, a secondary lumen communicating with a secondary lumen aperture and a tertiary lumen communicating with a tertiary lumen aperture. The secondary lumen aperture and the tertiary lumen aperture can be disposed at an equal longitudinal length from the primary lumen aperture. The RICC can include intricate tip structures formed from different materials and can define a smooth abluminal surface.

Circular catheter with non-circular shaping wire

A catheter has a body including a proximal region, a neck region, and a distal region. A shaping wire is disposed within the distal region to predispose it into at least a partial loop, which may have a fixed or variable radius of curvature. The shaping wire includes a distal portion having a circular transverse cross-sectional shape and a proximal portion having a non-circular (e.g., rectangular) transverse cross-sectional shape. The proximal portion of the shaping wire can have a width-to-thickness ratio of at least about 4, such as about 4.67. A transition portion can promote a gradual transition from the circular to the non-circular transverse cross-sectional shape, for example by increasing a width of the shaping wire by about 0.001″ and/or by decreasing a thickness of the shaping wire by about 0.001″ for every about 0.004″ in length through the transition portion.

Introducer with expandable capabilities

An introducer may include a layered tubular member having an inner liner including at least one folded portion extending along a distal region of the inner liner in a delivery configuration; a reinforcing member disposed over at least a portion of the inner liner, the reinforcing member including a plurality of longitudinal spines defining a plurality of openings disposed between adjacent longitudinal spines, wherein each folded portion is circumferentially overlapped by one of the plurality of openings; and an outer sheath disposed over the reinforcing member, wherein the outer sheath includes at least one perforation circumferentially overlapping each folded portion; and a tip member fixedly attached to a tapered distal region of the layered tubular member. The inner liner may extend to a distal end of the layered tubular member. At least a portion of each folded portion may terminate proximal of the distal end of the layered tubular member.

Medical device inspection system

A medical device inspection system may include a base, a medical device holder on the base, a fiber scope holder on the base, a moveable roller moveably attached to the base such that it is free to rotate around an axis and move from a first position to a second position along the base, and a feeder coupled with the base for feeding a flexible portion of the fiber scope into a lumen of the medical device. During use, the flexible portion of the fiber scope may extend from the handle, around the moveable roller, and through the feeder to enter an opening in the lumen of the medical device.
