  • Patent number: 11219749
    Abstract: The embodiments disclosed herein relate to balloon catheter assemblies. The balloon catheter assemblies can include a hub, an elongated member, and an inflation balloon. The balloon catheter assemblies can also include a support wire having a proximal end that is longitudinally displaceable within a sleeve that is disposed in the catheter hub. A distal end of the support wire may be coupled to the inflation balloon at one or more positions.
    Type: Grant

  • Publication number: 20210128333
    Abstract: Medical devices and medical assemblies that have a lubricant disposed on an inner surface (e.g., balloons to be inflated within a cavity of a patient) are disclosed, along with related methods of use and manufacture. Such devices or assemblies may be passed through an elongate channel (e.g., a catheter channel or the working channel of an endoscope) and deployed distal of the elongate channel to adopt an expanded configuration. The devices or assemblies may then be compacted as they are withdrawn into the elongate channel after deployment. Some medical devices and assemblies comprising a lubricant on an inner surface of a balloon body may be more readily withdrawn into the elongate channel than embodiments that lack such a lubricant.

  • Patent number: 10086173
    Abstract: The embodiments disclosed herein relate to balloon catheter assemblies. The balloon catheter assemblies can include a plurality of ports, a junction hub, an elongated member, and an inflation balloon. The balloon catheter assemblies can also include a reinforced tubular shaft extending through the inflation balloon. The balloon catheter assemblies can also include a retaining mechanism that can be removably attached to the junction hub.

  • Patent number: 9446232
    Abstract: A highly flexible implantable lead that offers improved flexibility, fatigue life and fatigue and abrasion resistance improved reliability, effective electrode tissue contact with a small diameter and low risk of tissue damage during extraction. In one embodiment the lead is provided with both defibrillation electrodes and pacing/sensing electrodes. For defibrillation/pacing leads, the lead diameter may be as small as six French or smaller. The construction utilizes helically wound conductors. For leads incorporating multiple separate conductors, many of the helically wound conductors are arranged in a multi-filar relationship. Preferably, each conductor is a length of wire that is uninsulated at about the middle of its length to create an electrode, wherein the conductor is folded in half at about the middle of the length to create first and second length segments that constitute parallel conductors.
