  • Patent number: 10751081
    Abstract: An epidural space is cleared of fat and scar tissue in preparation for implantation of a medical lead by utilizing a clearing tool. The clearing tool has an outer body and an inner body present within a lumen of the outer body. The outer body may be malleable and have a pre-set deflection or may be flexible and achieve deflection when being inserted into the epidural space. Once in the epidural space, the inner body is extended distally from the lumen of the outer body such that a distal tip on the inner body extends further into the epidural space to provide clearing to the target site without requiring further ingress of the outer body. The inner body is retracted and the clearing tool is removed. The medical lead is then inserted through the window and cleared epidural space until reaching the target site.

  • Publication number: 20190190215
    Abstract: Distal connector assemblies that are on the distal end of medical lead extensions provide increased rigidity by including a rigid holder that contains the electrical connectors. The electrical connectors are separated within the rigid holder by insulative spacers that may be individual items or may be formed from a compliant carrier that the electrical connectors may reside within where the carrier is positioned within the rigid holder. The rigid holder may also contain a set screw block defining set screw bore or the rigid holder may include an integral portion that defines a set screw bore. The integral portion may include a slot to allow a molding pin loaded with the electrical connectors and other components to be dropped into a cavity of the rigid holder. An overmold may be present to surround the rigid body containing the electrical connectors and insulative spacers.

  • Patent number: 8348858
    Abstract: A guide wire for magnetically navigating a medical device through in a subject's body comprising an elongate wire having a proximal and distal end, a portion adjacent the distal end that is more flexible than the more proximal portions of the elongate wire, and a first magnetically responsive element on the distal end of the elongate wire. The guide wire further comprises one or more magnetically responsive elements spaced apart from the first magnetically responsive element and disposed on the more flexible portion of the elongate wire. The guide wire provides for bending or deflecting the distal end of the stent, to provide easier navigation of the distal end of the guide wire and the stent through the vasculature of a subject body.

  • Patent number: 6475226
    Abstract: Devices and methods for percutaneous translumenal minimally invasive coronary surgery, particularly bypass surgery involving the following basic steps: determining a proper location for treatment, navigating a suitable device to the treatment site, creating an extravascular opening and pathway, guiding and/or monitoring the progress of creating the opening and pathway, and maintaining the extravascular opening and pathway. One or more extravascular openings and/or pathways may be created to define a fluid path or bypass around the vascular restriction. For example, an intravascular catheter for creating an extravascular opening in a vessel wall includes an elongate shaft adapted for intravascular navigation, an anchoring mechanism disposed on the distal end of the shaft, and a tissue penetrating member having a proximal end slidably disposed in the shaft and a distal end including a tissue penetrating mechanism.

  • Patent number: 6190354
    Abstract: A balloon catheter which has an elongate shaft with an inflatable balloon connected to its distal end and a manifold connected to its proximal end. The manifold may be fixedly or removably attached to the shaft and includes a barrel with a plunger movably disposed inside it. The barrel has an internal volume of less than 5 cc and an internal diameter of less than 0.25 inches. A pressure transducer may be mounted to the manifold to permit measurement via a sensor tube. A pressure source for a balloon catheter including a barrel with a plunger inside it. The barrel is in fluid communication with the inflation lumen of the catheter and has an internal volume less than 5 cc and an internal diameter of less than 0.25 inches. A pressure sensor may be connected to the barrel with a sensor tube defining a fluid path from the interior of the barrel to the pressure sensor. A lock mechanism may be connected to the barrel to control longitudinal movement of the plunger.
