    Abstract: An electrical stimulation device comprises a stimulation lead with an adjustable length tension sleeve to prevent induction of an electrical current when the electrical stimulation device is in the presence of a magnetic field generated by a device such as an MRI machine. The tension sleeve is shaped to organize excess length of the stimulation lead while providing a variable length between a distal end of the stimulation lead and an electrical source. The shape of the tension sleeve avoids coils and may utilize combinations of straight and curved legs that lie substantially in a common plane to both organize excess length of the stimulation lead and prevent electrical induction.

  • Patent number: 10159822
    Abstract: A method of treating lower leg ischemia in a patient includes advancing a wire guide upstream through a vascular access sheath extending into an artery of the patient at a percutaneous entry point in the lower leg, and increasing a downstream flow of blood through the artery at least in part by dilating a constriction in the artery with a treatment mechanism guided into the constriction via the wire guide. A low profile balloon may be used as the treatment mechanism, and is advanced through the artery while the vascular access sheath protects the artery from irritation such that spasm of the artery is less likely to occur. Reduced risk of spasm advantageously enables retrograde access to chronic total occlusions such that multiple entry points into a patient's body are not necessary.

  • Patent number: 8556857
    Abstract: Guidewire exit ramp members that may be placed over a tubular member having a guidewire lumen, which longitudinally extending and laterally accessible, and methods of use. The guidewire exit ramp member can be placed to force a guidewire loaded through the lumen in a first direction to be forced out of the lumen via an opening, slit or channel. The guidewire exit ramp member, in an illustrative embodiment, takes the form of a relatively short member having a proximal portion and a distally extending flap. The flap may be designed to enter and remain in a longitudinally accessible guidewire lumen. Combinations of such ramp members and device shafts having longitudinally extending laterally accessible guidewire lumens are also disclosed, as are methods for securing such combinations together. A method of backloading a guidewire into a catheter while causing lateral exit of the guidewire at a desired location is also shown.

  • Patent number: 8382714
    Abstract: A rail-guided epidural-spinal needle, which includes an epidural needle including a base and a needle shaft connected to the base, the needle shaft having a groove that is formed on an outer surface of the needle shaft and extends along an axis of the needle shaft, the base having an elevated spinal needle inlet disposed thereon, the spinal needle inlet having a conduit formed therein, the conduit being of an acute angle with the groove in a side view of the epidural needle, and being in alignment with the groove in a top view of the epidural needle. The rail-guided epidural-spinal needle also includes a spinal needle having a tip with a unilaterally curved conformation down one side, such that, when the spinal needle is inserted into the conduit of the spinal needle inlet, and pushed forward, the tip thereof reaches the groove and slides along the groove.

  • Patent number: 8251975
    Abstract: A catheter for introduction and removal of fluids from a body and tunneling device therefor, the catheter has a body having a first conduit for removing fluid from the body and a second conduit for delivering fluid to the body wherein at least a part of each of the conduits is integrally formed within a first end of the body of the catheter and extends along side one another. The first conduit extends beyond the second conduit and forms a terminal point of the first end and defines a first opening thereat and the second conduit extends to a point short of the terminal point defining a second opening. A bumper portion is adjacent the second opening extending toward the terminal point. Another part of each the first and the second conduits are disjoined and form part of a second Y-shaped end. The tunneling device has a channel to removably receive the catheter.

  • Patent number: 8012127
    Abstract: Systems for gaining access into a body of a patient around an implanted body of an elongate medical device include a sheath having a deformable wall that allows insertion of the device body into a lumen surrounded by the sheath wall. The sheath wall may include first and second edges that extend from a proximal end to a distal end of the lumen, or just extend along a distal portion of the lumen. A tool, which includes a groove sized to grasp about a circumference of the device body, may facilitate insertion of the device body into the lumen of those sheath embodiments that include the first and second edges, by spreading at least one of the first and second edges of the wall apart from the other of the first and second edges while the device body is grasped within the tool.

  • Patent number: 7985232
    Abstract: A system for connecting a hemostasis valve to a splittable sheath includes an interface formed between a ledge on the proximal end of a cannula portion of the hemostasis valve and an engagement structure aligned with the handles of the splittable sheath. Pulling the handles to split the sheath likewise disengages the ledge from the engagement structure. A snap ring on the cannula portion engages a snap ring in the lumen of a sheath hub formed on the proximal end of the splittable sheath. An O-ring between the cannula portion and the sheath hub provides a fluid-tight seal.
