    摘要: Methods and apparatus of forming in situ tissue adherent barriers are provided using a sprayer capable of applying two or more viscous crosslinkable solutions to tissue. The sprayer comprises separate spray nozzles for each of two or more crosslinkable solutions, wherein each nozzle is either surrounded by an annular gas flow outlet or in communication with a gas-pressurized chamber, and also may include valves that prevent backflow through the supply lines carrying the crosslinkable solutions, and a venting system for venting excess pressure for laparoscopic applications In the presence of gas flow, the crosslinkable solutions are atomized and mixed to form a spray. Multi-component hydrogel systems suitable for use with the inventive methods and apparatus are also described.

    摘要: Disclosed are methods, devices and materials for the in situ formation of an implant for treating a nerve. A treatment site on a nerve is positioned within a cavity defined by a form. A transformable media is introduced into the form cavity to surround the treatment site. The media is permitted to undergo a transformation from a first, relatively flowable state to a second, relatively non flowable state to form a protective barrier surrounding the treatment site. The implant may be a growth inhibiting nerve cap to inhibit neuroma formation following planned or traumatic nerve injury, a growth permissive conduit for facilitating reconnection of a severed nerve, or an anchor for stabilizing a pain management electrode with respect to a nerve. Access to the nerve treatment site may be open surgical or percutaneous.

    摘要: An anchor strain relief member provides resistance to disengagement from a hemostatic valve due to forces tending to force the catheter in a proximal direction. The anchoring strain relief member is distal to a hub, joined to the catheter outer surface, and comprises a sealing portion that has at least one ridge that has a ridge tip and a ridge height defined by a distance from the ridge tip to the catheter central axis. Methods of forming a nested catheter system are described using a catheter with an anchor strain relief as the inner catheter for the nested catheter set. Systems of a hemostatic valve and a suitable catheter with an anchor strain relief member can provide for desired assemblies of components.

    摘要: A catheter is provided comprising localized regions of modified flexibility. The regions of modified flexibility may comprise a softened inner liner, for example softened via stretching the inner liner or disposing a plurality of holes in the inner liner, to modify the bending stiffness and/or tensile stiffness of the catheter. The catheter may further include an axially extending filament that at least partially overlaps the softened portion of the inner liner. The axially extending filament may include an anchoring section to anchor the at least one axially extending filament in a section of the catheter that includes the helical coil.

    摘要: An aspiration catheter is provided including a proximal section and a distal section extendable through the proximal section. A vacuum transfer tool may be coupled to a proximal end of the proximal section. The vacuum transfer tool may include a proximal transfer tube and a distal transfer tube, each having an aspiration port in communication with a vacuum source. The proximal transfer tube may be removably received within a proximal end of the distal transfer tube. The proximal transfer tube may maintain a vacuum around the proximal end of the distal section of the catheter such that when the distal section is removed by decoupling the proximal and distal transfer tubes, the vacuum within the distal transfer tube and proximal section of the catheter is maintained, preventing the escape of any clots.
