Vascular access instrument having a fluid permeable structure, and related devices and methods
A delivery device to deliver a guidewire through an intravenous catheter assembly may include a housing, which may include a distal end, a proximal end, and a slot. The delivery device may include a guidewire, which may include a proximal end and a distal end. The delivery device may include a guidewire hub disposed within the housing. The guidewire may be secured to the guidewire hub, and the guidewire hub may be configured to move along the slot to advance the guidewire in a distal direction. The distal end of the guidewire may include a fluid permeable structure. For example, the fluid permeable structure may include an elongated core and a coil extending around the elongated core. In some embodiments, a space between the elongated core and the coil may be configured to receive blood in response to the guidewire being inserted into the vasculature.
GUIDEWIRE MANIPULATION DEVICE
One preferred embodiment includes a guidewire manipulation device for manipulating a guidewire during a procedure. Preferably, the guidewire manipulation device includes a powered motor that drives a tandem roller assembly. The guidewire is passed through a hole positioned lengthwise through the device where the roller assembly engages the guidewire's outer surface. The interface of the manipulation device includes a power button that directs the internal roller assembly to roll the guidewire in a desired rotational direction. Additional interface controls are also preferable to provide a different roll patterns, depending upon surgeon preference and guidewire placement efficiency.
STEERABLE ENDOLUMINAL PUNCH
A steerable transseptal punch system and method of using the steerable transseptal punch system to access the left atrium.
DEVICES AND METHODS FOR GUIDEWIRE MANAGEMENT
Devices and methods for management of a guidewire during catheter insertion. Particular embodiments include unidirectional valves to allow movement of a guidewire in one direction only.
Wire Holder for Sterile Field
A wire manager for managing wires in a sterile field includes a body having a plurality of slots on a front side of the body and an adhesive material disposed on a back side of the body for temporarily adhering the body to a surface of the sterile field. A finger tab is formed on a side surface of the body for facilitating removal of the body from the surface on which the body is installed. The adhesive material provides for adhesion to the surface and removal from the surface by way of lifting the body using the finger tab.
MEDICAL LIQUID INJECTION DEVICE
A medical liquid injection device including a catheter with a hollow shaft having a lumen formed inside to contain medical liquid, a wire to be inserted into the lumen, and a wire moving device to move the wire forward inside the lumen from a proximal end to a distal end side in accordance with a control signal, thereby ejecting a predetermined amount of the medical liquid from the distal end of the hollow shaft.
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.
MEDICAL SYSTEMS, DEVICES, AND RELATED METHODS
According to one aspect, a method for removing material from a body lumen is disclosed. The method may include positioning a first medical device within the body lumen; and expanding an expandable member at a distal portion of the first medical device from a retracted state to an expanded state. The expandable member may abut the body lumen in the expanded state. The method may further include providing fluid to a fluid lumen of the first medical device, wherein the fluid is deployed into the body lumen; applying an ultrasound signal to the first medical device from a second medical device; and moving the first medical device distally through the body lumen while the expandable member is in an expanded state, to remove material from the body lumen.
Expandable tip medical devices and methods
Guidewires and methods of use of guidewires having improved atraumatic tips that can distribute force to lessen trauma as well as anchor the guidewire to facilitate improved catheter exchange.
Catheter placement device
A deep vein intravenous introducer has a wheel located toward the front end of the device that can be rotated by the index finger of the user. After placement of the needle in the lumen of the vessel, the user rotates the wheel, which turns a drive wheel. The drive wheel has an outer surface that advances the guide wire through the center of the needle and into the patient. Once the guide wire is advanced into the vessel lumen the catheter can be advanced over the guide wire with a hub or finger tab on the catheter close to the index finger. The operation can be performed by one hand without moving the hand from its initial position.
