    摘要： An integrated inflation/deflation device provides easy, precise delivery of a small amount of fluid for proper inflation of a low volume surgical balloon and similarly provides easy and fast deflation of the balloon. A preferred embodiment includes a low volume syringe and large syringe mounted together within a housing. A port in the low volume syringe is in communication with the large syringe barrel. The low volume syringe plunger is controlled by a knob disposed on the housing. The large syringe is used to prime the surgical balloon system, including a catheter, and the low volume syringe delivers a precise, predetermined volume of fluid to inflate the balloon. The low volume syringe is also used to deflate the balloon. Preferably, indicia on the housing adjacent the knob direct the required rotation of the knob to deliver the correct volume of fluid to be injected to match a balloon of a given size and shape so that the balloon is properly inflated.

    摘要： Described herein are devices, systems and methods for cutting tissue in a patient. In some embodiments, a tissue modification region of a device includes a pair of flexible elongate cutting members extending along the length of the tissue modification region. Each elongate cutting member may be configured to cut a discrete trough into tissue to a depth that is greater than the thickness of the cutting member. In some embodiments, the device includes a spacer. The spacer may be sized and configured to operate in one of two modes. A first mode, in which the spacer is coupled to the cutting members such that it holds a portion of each of the two cutting members a distance from one another, and a second mode, in which at least a portion of the spacer is moved away from a cutting member to allow the cutting members to cut further into tissue.

    摘要： Described herein are methods and systems for precisely placing and/or manipulating devices within the body by first positioning a guidewire or pullwire through the body from a first location, around a curved pathway, and out of the body through a second location, so that the distal and proximal ends of the guidewire extend from the body, then pulling a device into position using the guidewire. The device to be positioned within the body is coupled to the proximal end of the guidewire, and the device is pulled into the body by pulling on the distal end of the guidewire that extends from the body. The device may be bimanually manipulated by pulling the guidewire distally, and an attachment to the device that extends proximally, allowing control of both the proximal and the distal ends. In this manner devices (and particularly implants such as innerspinous distracters, stimulating leads, and disc slings) may be positioned and/or manipulated within the body. Devices to modify tissue may also be positioned or manipulated so that a target tissue within the body is modified.

    摘要： Described herein are devices and methods for positioning a wire around a target tissue. In some embodiments, a probe device includes a rigid outer cannula having a curved distal region and a flexible inner cannula slideably disposed within the rigid outer cannula, wherein the inner cannula is configured to assume a curved shape when extended distally from the outer cannula. In some embodiments, the probe device further includes a distal tip at the distal end of the inner cannula and a safety retainer cable coupled to the distal tip and secured to the probe proximally from the distal end of the safety retainer; wherein the safety retainer cable extends proximally from the distal tip and is slack. In some embodiments, the inner cannula comprises an elongate body with a longitudinally extending support member and a longitudinally extending tubular body, configured to pass a wire, disposed inside the elongate body.
