Subcutaneous implantable device for guiding a vascular access member and method for vascular access
A subcutaneous implantable device for guiding a vascular access member, the device including a channel defined by a through-hole in the device, wherein the channel is configured to guide the vascular access member there-through to a vascular site; and anchoring means adapted for fixedly attaching, in a form of using suture, tissue ingrowth, tissue encapsulation or tissue adhesion, the device to at least one of a dermis or a subcutaneous tissue at a position underneath the dermis to allow repeated access of the vascular access member through the channel to the vascular site, wherein the device is dimensioned to allow the device to be attached through the anchoring means for anchoring the entire device at a distance away from the vascular site, A method of creating scar tissue track for vascular access is also disclosed where the subcutaneous implantable device for guiding vascular access member is first implanted sub-dermally, the dermis is palpated to feel for the device location and orientation, the guiding channel is accessed using the sharp vascular access member and following the angle of the guiding channel to access the vascular site and repeating the steps till scarred tissue track is created and finally, switching the sharp vascular access member to a blunt vascular access member to access the vascular site via the scarred tissue track.
Multiply Sealed Access Port and Companion Devices
An access port for transporting fluids into a patient's body utilizing a multiple seals in parallel is disclosed. The access port 100 includes a flanged base 102, a receptacle 106 with multiple seals 108 and 110, and a cannula 104. The access port may also include a guide needle for installation purposes, and a sanitary adaptor that seals the receptacle for long term usage. Adhesives or bandaging may utilize the flanged base to secure the access port to the patient. The flanged base may also be installed beneath the patient's skin so secure the access port. The receptacle utilizes a multitude of sealing mechanism, including but not limited to O-ring seals and screw-lock seals. The receptacle additionally contains and outlet flow path leading to the cannula. The cannula connects from the receptacle into the patient's body. The cannula is installed perpendicular to the plane of the flanged base and protrudes on the side of the access port facing into the patient's body while the receptacle faces outward. A number of devices may work in conjunction to access port 100 that interface with the multiple parallel seal mechanism. Guide needle 200 may be utilized during installation, sanitary seal 300 may be used for long term use, and band 500 in conjunction with bag 600 may be worn on a patient to deliver substances into their body. Programmable components 512, 606, and 712 may be implemented with these devices that enables a system that automatically identifies the substance being administered and dosing information, then relays that information to a doctor or caregiver.
ARTHROSCOPIC CANNULA AND SUTURE MANAGEMENT SYSTEM
A flexible portal cannula for use in arthroscopic surgery. Distally positioned flaps extend radially outwardly from the outer surface of the cannula and are resiliently foldable to lie against the outer surface of the cannula during insertion into a surgical portal, and resiliently biased to return to the radially outwardly extending position when unconstrained. A clip disposed on the cannula outer surface outside of an arthroscopic workspace acts to clamp tissue disposed between the clip and the flaps. The clip has an extension to receive pairs of slots to sort and engage the sutures.
VACUUM ASSISTED SKIN PENETRATING APPLIANCE WITH EXTERNAL INTERFACE
An external protective interface is provided for intravenous infusion lines, drive lines, vacuum lines, and monitoring lines for percutaneous access. The interface acts as an airtight seal in concert with a vacuum line to promote accelerated tissue healing to reduce and prevent infection at insertion sites for infusion lines, drive lines, and medical devices. The interface provides additional mechanical stability to an implanted tube or PAD or so as to speed healing around a semi-permanent implanted tube or PAD, as well as connection points for vacuum lines and at least one drive line for the insertion of medical devices. The dense fibroblast ingrowth encouraged by the interface acts to strengthen barriers to infection at the insertion site.
Port Tunneling Systems And Methods Thereof
Provided herein is a system including, in some embodiments, a streamlined port and a port tunneler. The port includes a septum and a stabilizing element. The septum is disposed over a cavity in a body of the port, and the septum is configured to accept a needle therethrough. The stabilizing element is configured to stabilize the port in vivo and maintain needle access to the septum. The port tunneler includes an adapter and a release mechanism. The adapter is in a distal end portion of the port tunneler, and the adapter is configured to securely hold the port while subcutaneously tunneling the port from an incision site to an implantation site for the port. The release mechanism is configured to release the port from the adapter at the implantation site for the port.
Neurological apparatus comprising a percutaneous access device
Apparatus for delivering therapeutic agents to the central nervous system of a subject is described. The apparatus includes at least one intracranial catheter and a percutaneous access device. The percutaneous access device includes a body having at least one extracorporeal surface and at least one subcutaneous surface, the body defining at least one port for connection to an implanted intracranial catheter. The port is accessible from the extracorporeal surface of the device, but is provided with a seal such as a rubber bung between the lumen of the port and the extracorporeal surface. The percutaneous access device may have more than two ports and/or a flange. A method of implanting the percutaneous access device is also described.
Drainage devices and methods for use
Devices and methods for draining excess lymph fluid are disclosed. The device can be fixed to the blood vessel adjacent to the thoracic duct. The device can have a port for withdrawing lymph fluid exiting the thoracic duct. The device can have a cannula and/or subcutaneous port to draw the lymph fluid away from the thoracic duct and reduce hemostatic pressure in the lymphatic system.
T-SHAPED CATHETER
The present invention provides a T- or Y-shaped catheter device for creating a permanent/long-term vascular access point for a patient in need of repetitive infusions/access or dialysis.
CRYOLIPOLYSIS DEVICES AND METHODS THEREFOR
Described herein are cryolipolysis devices, systems, and methods for facilitating percutaneous access to a target blood vessel by performing cryolipolysis on subcutaneous adipose tissue obscuring the target blood vessel (e.g., a vessel used for hemodialysis treatment). Generally, the devices include a cooling member carrying a coolant that cools a selected portion of adipose tissue overlying the target blood vessel to reduce the selected portion of adipose tissue, thereby forming a depression in the adipose tissue and allowing the target blood vessel closer to the surface of the skin. In some variations, the cooling member is placed subcutaneously to directly cool the selected portion of adipose tissue. In other variations, the cooling member is placed external to the patient to indirectly cool the selected portion of adipose tissue through the skin.
INTRAVENOUS THERAPY SYSTEM FOR BLOOD VESSEL DETECTION AND VASCULAR ACCESS DEVICE PLACEMENT
An intravenous therapy system, may include a processor; a data storage device; and a handheld ultrasound probe to detect structures within a patient's body, the handheld ultrasound probe including a video display device physically and operatively coupled to the handheld to display the structures within the patient's body and a magnetic field detector to detect the presence of a vascular access device (VAD) and provide closed-loop feedback to guide the VAD into a blood vessel within the patient's body detected by the ultrasound probe.
