Abstract: Provided are methods and systems for network access control. A method for network access control may commence with determining whether a client device is a trusted source or an untrusted source. The determination may be performed using a SYN packet received from the client device. The SYN packet may include identifying information for the client device. When it is determined that the client device is neither the trusted source nor the untrusted source, the method may continue with transmitting a SYN/ACK packet to the client device. The SYN/ACK packet may include a SYN cookie and identifying information for a network device. The method may further include receiving an ACK packet from the client device that may include the identifying information for the client device, identifying information for the network device, and the SYN cookie. The method may continue with establishing a connection with a network for the client device.

Abstract: A catheter adapted or high density mapping and/or ablation of tissue surface has a distal electrode array with offset spine loops, each spine loop having at least a pair of linear portions and a distal portion connecting the pair of linear portions, and one or more electrodes on each linear portion. The linear portions of the plurality of offset spine loops are arranged in-plane a single common plane, and the distal portions of the plurality of offset spine loops are arranged off-plane from the single common plane.

Abstract: Network access control systems and methods are provided herein. A method includes receiving at a network device a SYN packet from a client device over a network, determining if the client device is a trusted source for the network using the SYN packet, if the client device is a trusted resource, receiving an acknowledgement (ACK) packet from the client device that includes identifying information for the client device plus an additional value, and identifying information for the network device, and establishing a connection with the network for the client device.

Abstract: Aspine that may be used in the electrode assembly of an electrophysiologic catheter having controlled flexibility. The spine may have a flexible core that extends through a length of the spine, a polymeric cover and a plurality of electrodes, each having at least one lead, distributed longitudinally along the spine. An amount of material forming the spine may be adjusted longitudinally along the spine to compensate for changes in flexibility to the spine caused by varying numbers of electrode leads present at different relative longitudinal positions along the spine.

Abstract: A catheter comprising an elongated catheter body, an electrode array distal of the catheter body, the array having a mounting member and at least first and second spine supports. Each spine support includes a base having a planar configuration, and a plurality of spines extending from the base, wherein the first base extends in a first plane and the second base extends in a second plane different from the first plane in the mounting member.

Abstract: This disclosure is directed to a catheter having a basket-shaped electrode assembly with a high electrode density. The basket-shaped electrode assembly may have a plurality of spines, such as up to twelve, each with a plurality of electrodes, such as up to sixteen. The distal ends of the plurality of spines are joined at a distal hub, all of which are fashioned from a single piece of superelastic material.

Abstract: A catheter sheath introducer comprises a hub and a tubular sheath having an inner lining with one or more dampers to improve retention of medical devices received or passed through the sheath without significantly increasing the force required to advance the medical device through the sheath. The dampers are made of a friction inducing material, for example, rubber-based materials, and configured as fingers, bumps or flaps that are unidirectional by means of an asymmetrical shape relative to a longitudinal axis of the sheath.

Abstract: This disclosure is directed to a catheter having a multi-electrode assembly with a high electrode density. The multi-electrode assembly may be a basket-shaped electrode assembly or a brush-shaped electrode assembly each having a plurality of spines. Each spine includes a flexible wire core of a shape memory material. The flexible wires may have variable cross-section s to control the movement and stiffness of the spines.
