Rapidly Insertable Central Catheters, Catheter Insertion Assemblies, and Methods
Rapidly insertable central catheters (“RICCs”), RICC insertion assemblies, and methods are disclosed. For example, a RICC insertion assembly can include a RICC, an introducer, and an access guidewire. An introducer needle can include a needle shaft having a longitudinal gap extending from a proximal portion of the needle shaft through a needle tip. An introducer sheath can include a splittable sheath hub coupled to a splittable sheath body. The introducer sheath can be disposed over the introducer needle with the sheath body sealing the needle shaft for drawing a vacuum through the introducer needle. The access guidewire can extend along an entirety of a primary lumen of the RICC, through a splittable valved port of the sheath hub, along a sheath body-covered needle channel of the needle shaft, and to a location in the introducer proximal of the needle tip in a ready-to-operate state of the RICC insertion assembly.
SYSTEMS AND METHODS FOR FACILITATING INSTRUMENT DELIVERY THROUGH A PERIPHERAL INTRAVENOUS CATHETER
A system for facilitating instrument delivery through a peripheral intravenous catheter may include a catheter adapter having a proximal end, a distal end, and a lumen extending there through. The catheter adapter may include a side port. The system may include an extension tube extending from the side port. The system may include a blood control valve disposed in the lumen of the catheter adapter. The system may include a peripheral intravenous catheter extending distally from the catheter adapter.
Low-Profile Single and Dual Vascular Access Device
A low-profile access port for subcutaneous implantation within a patient. The access port can include a set of receiving cups which can be placed in fluid communication with a catheter. The set of receiving cups can provide a greater skin surface with which to access the port to avoid repeated penetrations at a single locus, such as during consecutive dialysis treatments. The access port can alternatively include needle penetrable arms or elongate chambers that also have a slim, low profile. The access port can include a needle guide to direct subsequent needle access to different insertion points to permit healing at the previous insertion points. The access port can be formed of a modular construction with a first conduit, a second conduit, and an outer shell. The outer shell can include a proximal portion and a distal portion. The access port can include a stem assembly and a locking member.
All-in-one arterial access and closure system (ACS)
The present invention features an all-in-one system for vascular access and closure. In particular, this invention features systems and methods for forming holes in blood vessels and rapidly closing these vessel holes using an all-in-one system. For example, an arterial access and closure port system is disclosed herein to provide fail-safe percutaneous entry and exit into any artery, particularly useful for high flow and high pressure arteries such as the carotid artery. The present invention is a single system that forms and closes vascular holes and can be used for percutaneous arterial access with interventional radiology, interventional cardiology, neuro-intervention, endovascular surgery, and endovascular neurosurgery.
DIALYSIS SYSTEM AND APPARATUS WITH INLINE INDUCTIVE FLUID HEATING
An inductive inline dialysis fluid heater is disclosed. In an example, a dialysis fluid heater includes a cylindrical tube including an inner diameter that is between 4.00 millimeters (“mm”) and 12.7 mm. The dialysis fluid heater also includes a susceptor located within the cylindrical tube and an inductive coil extending around the cylindrical tube in a non-contacting arrangement. The dialysis fluid heater further includes power electronics in electrical communication with the inductive coil and configured to supply an electrical current to the inductive coil, causing the susceptor to heat.
CATHETER FOR CHEST DRAINAGE AND CHEST DRAINAGE SYSTEM
To reduce the suffering of the patient and enable easier removal of excess fluid such as pleural effusion fluid from the chest space, the disclosure provides a catheter for chest drainage intended for removal of excess fluid from a chest space of a living body and to be placed in the living body in such a manner as to extend from an inside of the chest space to an outside of the living body. The catheter includes a passage member formed of a flexible sheet and having a passage through which the excess fluid is to be drained, and an indwelling member formed of an elastic body and provided at a proximal end of the passage member. The indwelling member has an inlet that allows the excess fluid to flow through. The indwelling member includes a retaining portion spreading in a flange shape and being retainable at a chest wall.
Subcutaneous fixing system for medical devices
The present disclosure relates to a subcutaneous fixation system for fixing medical devices, in particular catheters, and keeping them in position with respect to an access point on the skin of a patient.
Implantable interface device
An interface device for implantation in a subject includes a tissue integration layer and a crowning element. The tissue integration layer has a porous structure adapted for ingress of tissue to anchor the device when implanted. The crowning element is adapted for epidermal attachment when the device is implanted and is configured such that once implanted, part of the crowning element extends through the epidermis and is accessible from outside the subject's body. The porous structure of the tissue integration layer is interconnected for tissue ingress during implantation.
Devices for transvascular retrograde access placement
The present invention relates to methods of transvascular retrograde access placement and to devices that facilitate these methods. For purposes of the present invention, transvascular retrograde access placement generally comprises the insertion of a vascular catheter into a central blood vessel through the puncturing of the central blood vessel from the inside of the central blood vessel with a needle or other similarly configured device, or a needle-tipped guidewire of the present invention, and exiting that needle from the patient through the skin rather than the traditional approach of inserting a needle from the outside of the skin surface to the inside of a blood vessel.
Low-profile single and dual vascular access device
A low-profile access port for subcutaneous implantation within a patient. The access port can include a set of receiving cups which can be placed in fluid communication with a catheter. The set of receiving cups can provide a greater skin surface with which to access the port to avoid repeated penetrations at a single locus, such as during consecutive dialysis treatments. The access port can alternatively include needle penetrable arms or elongate chambers that also have a slim, low profile. The access port can include a needle guide to direct subsequent needle access to different insertion points to permit healing at the previous insertion points. The access port can be formed of a modular construction with a first conduit, a second conduit, and an outer shell. The outer shell can include a proximal portion and a distal portion. The access port can include a stem assembly and a locking member.
