A catheter device and manufacturing process for manufacturing the catheter device, wherein the catheter device has a halo-shaped coiled portion extending away from a perpendicular stem portion through a swan neck portion. Eyelets on the halo coil portion and swan neck portion facilitate flow out of the bladder through the catheter device vertical to the catheter, rather than perpendicularly as is the case with existing catheters. The catheter device is formed by using a straight catheter tube, heating and cooling it within a formed mold to have the halo coil and swan neck, such that it can be straightened using a pusher and stylet, inserted into the body while straightened, and thereafter return to its coiled shape when the stylet is removed.

The present disclosure relates to methods of manufacture, apparatus, and fixtures. An apparatus comprising an inner liner having a hollow chamber extending the length of the inner liner, at least two guide rings disposed collectively along the inner liner, and at least one lumen portion extending through each of the at least two guide rings and being parallel with the hollow chamber, wherein the at least two components are fixed by welding is provided. Further provided is a fixture and a method of manufacture.

A medical shaft includes a shaft including at least one lumen extending in a longitudinal direction; a core member disposed in the lumen, the core member extending along the longitudinal direction; and a tubular member disposed on an outer side of the core member in a same lumen as a lumen in which the core member is disposed, the tubular member having a length, in the longitudinal direction, which is less than a length of the core member, wherein in the lumen, an area of a cross-section of the lumen on a plane perpendicular to the longitudinal direction in a portion in which the tubular member is disposed is greater than an area of a cross section of the lumen on a plane perpendicular to the longitudinal direction in a portion in which the tubular member is not disposed.

An introducer assembly includes a valve having a first end and an opposite second end; a sheath fixedly secured to and extending axially from one of the first and second ends of the valve; a dilator extending through the valve and sheath; and a lock knob rotatable between locked and unlocked positions to releasably axially lock the tool relative to the sheath without causing corresponding rotation of the tool therewith.

A support system, a support method, and a support program in the form of a non-transitory computer readable medium, which supports selection of a medical instrument and selection of a use form of the medical instrument. A support system includes the data acquisition unit that acquires health care worker data on a health care worker, medical institution data on a medical institution, patient data on a patient, and operation data on a past operation experience of the health care worker, a learning unit that performs machine learning using the health care worker data, the medical institution data, the patient data, and the operation data, and a presentation unit that presents a medical instrument recommended for use in operation on the patient and a recommended use form of the medical instrument based on a result of the machine learning.

Extended dwell catheter assemblies each with a housing having an interior having a catheter assembly located therein, which can include a catheter tube and a needle. The catheter tube of the catheter assembly can be placed into a vein of a patient, with or without a guidewire, and then the extended dwell catheter assembly can be activated to separate into two or more housing components or by opening a gate to enable separation of the catheter assembly from the housing. A needle guard can be included to cover the needle tip of the needle from unintended needlesticks.

Embodiments of the present disclosure can include a catheter. The catheter can include an elongate shaft including a proximal end and a distal end, the elongate shaft defining a shaft longitudinal axis. The catheter can include a coupler disposed within a distal end of the elongate shaft, wherein the coupler defines a first sensor groove and a second sensor groove in an exterior surface of the coupler and a coupler longitudinal axis. The catheter can include a first and second wire management feature located at a proximal end of each one of the first sensor groove and the second sensor groove.

Methods described herein can include drawing materials to form a drawn filled tubing (DFT) wire. The materials can include a core material, a first layer of a biocompatible material disposed exterior to the filler material, a magnetic material disposed external to the first layer of biocompatible material, and a second layer of biocompatible material disposed exterior to the magnetic material. In some embodiments, the method further comprises melting the core material to form a magnet with a through hole lumen. In some embodiments, the method can further include applying an external magnetic field to the materials during the drawing to align grains of the magnetic material. In some embodiments, the core material can have a melting point lower than a melting point of the magnetic material and the biocompatible material.

A method of manufacturing a catheter assembly including a proximal catheter assembly portion and a distal catheter assembly portion. The method of manufacturing comprises forming the proximal catheter assembly portion, creating a distal catheter assembly portion, and applying a polymeric coating to at least one of the proximal catheter assembly portion and the distal catheter assembly portion. The proximal catheter assembly portion can include a catheter hub and at least one cannula, the catheter hub including at least one fluid passageway in communication with a lumen of the at least one cannula. The distal catheter assembly portion can include a catheter tube defining at least one lumen designed to receive the at least one cannula. The polymeric coating is configured to provide a seal between the at least one cannula and the catheter tube when the proximal catheter assembly portion and the distal catheter assembly portion are connected.

The distal tip structure of a rapidly insertable central catheter (RICC) can be required to perform different functions from that of the remaining, multi-luminal section, of the RICC catheter. As such, the catheter body can be formed of a first material and the distal tip structure can be formed of a second material. Forming the RICC requires joining these two materials while maintaining a smooth abluminal surface. A bifurcated plug including a second material can be placed within a first lumen or second lumen of the catheter body. A mandrel can be placed within a third lumen. The assembly can then be placed within a die to plastically deform the bifurcated plug into a distal tip structure. Advantageously, only a single structure is required to plug the lumen and form the distal tip structure, reducing complexity and associated costs.
