WIRELESS CHARGING, LOCALIZATION, AND DATA COMMUNICATION FOR IMPLANTABLE VASCULAR ACCESS DEVICES
An implantable vascular access device includes a fluid, a self-sealing cover disposed over the reservoir, and an outlet port configured to mate with a catheter, the outlet port fluidically coupled to the fluid reservoir. One or more sensors coupled to the device are configured to capture physiological data while the device is implanted within a patient. The device also includes a data communications unit configured to receive physiological data from the one or more sensors, obfuscate the physiological data, and transmit the obfuscated physiological data to one or more remote computing devices. The device may also be inductively powered and/or can emit a localization signal in response to wireless interrogation.
VALVE SYSTEMS AND STEERING SYSTEMS FOR CATHETERS AND METHODS OF USE
Valve systems and steering systems for catheters and methods of using the same.
Fluid transfer devices with extended length catheters and methods of using the same
An apparatus includes a housing, a catheter, and an actuator. The housing has a first port and a second port that is coupleable to an indwelling vascular access device. The catheter is at least partially disposed in the housing such that the first port of the housing receives a proximal end portion of the catheter. The actuator is partially disposed in the housing to selectively engage a portion of the catheter in the housing. The actuator is configured to be rotated an angular distance relative to the housing to move a distal end portion of the catheter a linear distance from a first position inside the housing, to a second position in which the catheter extends through the second port and distal to the indwelling vascular access device when the second port is coupled thereto. The linear distance is greater than the angular distance.
VASCULAR ACCESS INSTRUMENT AND RELATED DEVICES AND METHODS
A vascular access system may include a catheter assembly, which may include a catheter adapter and a catheter extending distally from the catheter adapter. The vascular access system may include an instrument advancement device coupled to the catheter assembly. The instrument advancement device may include a vascular access instrument. The vascular access instrument may include a coil formed by a flat wire wound around an axis into multiple loops. The instrument advancement device may be configured to advance the vascular access instrument from a retracted position to an advanced position beyond a distal end of the catheter. The distal end of the catheter may include a distal opening. The coil may extend through the distal opening of the catheter in response to the vascular access instrument being in the advanced position.
IMPLANTABLE DEVICE FOR DETERMINING A FLUID VOLUME FLOW THROUGH A BLOOD VESSEL
The invention relates to an implantable device (1) for determining a fluid volume flow (2) through a blood vessel (3), comprising: —at least one sensor (4) for recording at least one flow parameter, —a retaining means (5) for retaining a vessel wall port (6) in the region of a vessel wall (7) of the blood vessel (3), wherein the retaining means (5) is formed to retain the at least one sensor (4) in the region of the vessel wall (7).
CONNECTION OF INTRAVASCULAR INTERVENTIONAL ELEMENTS AND ELONGATE MANIPULATION MEMBERS
A device for intravascular intervention can comprise an interventional element, an elongate manipulation member having a retention portion, and a joining element. The elongate element can comprise a distally located attachment portion. The interventional element includes a proximal end portion with a hole therethrough, the attachment portion of the elongate member extending through the hole at the bend such that first and second segments of the elongate member each extend proximally from the hole. A retention portion includes an arm extends proximally of the hole and a shoulder protruding radially outwardly from a proximal portion of the arm. A joining element circumferentially surrounds at least a portion of the retention portion and at least a portion of the first and second segments of the elongate member such that a proximal end of the joining element is positioned distal to the shoulder of the retention portion.
Introducer with partially annealed reinforcement element and related systems and methods
The present disclosure illustrates an introducer sheath with a partially annealed metal frame. The introducer sheaths described herein include a hub coupled to a shaft. The shaft comprises a braided wire frame with (i) an annealed distal portion that prevents the braided wire frame from unraveling at a distal end, and (ii) a second portion that is unannealed; a jacket encompassing the braided wire frame; and a liner forming an inner wall.
Stabilizing connector devices for vascular access and methods of using the same
A stabilizing connector includes a connector portion and a stabilization portion. The connector portion is configured to couple to an access device. The connector portion defines at least one lumen that is configured to be placed in fluid communication with a lumen of the access device. The stabilization portion is coupled to the connector portion. The stabilization portion is configured to be placed in contact with a surface of a patient's skin to stabilize at least one of the stabilizing connector or the access device.
Intraosseous Device and Data Transfer
Disclosed herein are medical device systems, and methods thereof. Exemplary medical devices can include intraosseous (IO) access device systems, or similar medical devices that include a motive force. Embodiments include replaceable and rechargeable batteries that are configured to store one or more performance characteristics of the medical device and transfer the performance characteristic to a base station when the battery is removed from the medical device and coupled with the base station for recharging. The base station can then store performance characteristics from one or more batteries and/or medical devices. The performance characteristics can be transferred from the base station to one or more external computing devices or networks.
Point of injury device to stabilize intracranial pressure and method of stabilization
A minimally invasive system for monitoring and treating high intracranial pressure levels resulting from traumatic brain injury comprises an intravenous access device, an elongate member, a console, and an aspiration and injection catheter. The system is capable of monitoring pressure levels and relocating fluid from the brain to another part of the patient's body to sustain overall constant fluid volume. The method of using the minimally invasive system is also described.
