摘要： Apparatuses and methods for accessing and disrupting a tissue are disclosed herein. In one embodiment, a method includes inserting a distal end portion of a medical device into a biological body such that a cutting member disposed at a distal end of the medical device is at a first location within the biological body. A tissue is disrupted at the first location within the biological body. The distal end portion of the medical device is reconfigured from a first configuration in which the distal end portion of the medical device has a first curvature to a second configuration in which the distal end portion of the medical device has a second curvature different than the first curvature and the cutting member is at a second location within the biological body. A tissue is then disrupted at the second location within the biological body.

摘要： Balloon cannula systems may be used for accessing and visualizing the spine and related methods of treatment, including a forward-looking balloon system for creating a working space and the balloon system having atraumatic dissection capability to allow visualization in spine. The devices and methods described may be used, for example, to perform annulus repair, herniated disc excision, and denervation of neurological tissue; to dispense pharmacological agents and/or cell or tissue therapy agents; to diagnose disc degeneration and bony degeneration, spinal stenosis, and nucleus decompression, and to perform disc augmentation.

摘要： Stent and stent delivery system suited for the noninvasive treatment of aneurysms, diseased blood vessels, and other bodily lumen are described. Detachable proximal and/or distal wires connected to the proximal and distal ends, respectively, of the stent allow the operator to manipulate the position and final configuration of the stent upon deployment.

摘要： A device for accessing the spinal canal of a patient includes an introducer and a protective sleeve that is attached at one end thereof to a proximal end of the introducer. The protective sleeve has an outer stationary portion and an inner moveable portion. The outer and inner portions of the protective sleeve are separated by a crown region. A catheter is disposed inside the protective sleeve. During operation, the protective sleeve is advanced within the spinal canal to form a protective barrier between the catheter and the spinal cord. The catheter is advanced and retracted within the protective sleeve.

摘要： This is a catheter suitable for accessing a tissue target within the body, typically a target which is accessible through the vascular system. Central to the concept of the catheter is the use of a reinforcing member wound within the catheter body in such a way to create a catheter having an exceptionally thin wall, excellent kink-resistance, and controlled stiffness. The catheter assembly desirably is constructed of: (a) an inner, polymeric, lubricious liner, (b) a first, helically wound coil over at least the more distal portions of the inner liner, (c) a second, helically wound coil exterior to the first coil located at least on the more proximal portion of the assembly, and (d) one or more outer polymeric coverings exterior to the second coil. Further polymeric layers may also be placed between the outer polymeric covering and the helically wound coils. The outer polymeric covering may be composed of a series of different polymeric compositions to provide suitably differing flexibilities to the assembly. The catheter assembly is quite easy to produce. The helically wound coils are desirably bound to the assembly via the use of radio-opaque bands or coils and preferably are continuously wound from a single member. The distal-most portion of the catheter assembly is very flexible but highly kink resistant.

摘要： This invention is a surgical device. In particular, it is a catheter suitable for accessing a tissue target within the body, typically a target which is accessible through the vascular system. Central to the invention is the use of at least pair of wound or counterwound reinforcing members situated within the wall of the catheter body in such a way to achieve a catheter having an exceptionally thin wall, excellent kink-resistance, and controlled stiffness. The catheter assembly desirably is constructed of: (a) an inner, polymeric, lubricious liner, (b) a first, helically wound coil extending over at least the more distal portions of the inner liner but preferably for most of the length of the catheter, (c) a second, helically wound coil exterior to the first coil, located at least on the more proximal portion of the assembly but preferably for most of the length of the catheter, preferably wound in a direction opposite to the first coil, (d) optionally, one or more helically wound coils placed on the proximal and mid-section of the assembly, and (e) one or more polymeric layers variously exterior to the second coil and interior to the first coil. Preferably, the coils are wound from metallic ribbons or wireshaving a relatively constant pitch of from 10.degree.-15.degree. of the central catheter axis. Further polymeric layers may also be placed between the outer polymeric covering and various and the helically wound coils. The outer polymeric covering may be composed of a series of different polymeric compositions to provide suitably differing flexibilities along the length of the assembly. The catheter assembly is quite easy to produce. The helically wound coils may be bound to the assembly via the use of radio-opaque bands or coils and may be continuously wound from a single member. The distal-most portion of the catheter assembly is very flexible but highly kink resistant. Optionally, the invention includes a catheter in which only the more distal catheter section incorporates multiple coil stiffener members.
