A medical balloon device includes an outer member extending along an axis. An inflatable member has a proximal end extending from a first end of the outer member and a distal end. An inner member is positioned within the outer member and the inflatable member such that a first end of the inner member is coupled to the distal end of the inflatable member. A support member is movably disposed within the inner member and includes a first end configured to removably engage the first end of the inner member. Translation of the support member along the axis causes the inflatable member to move between a first position in which the inflatable member has a first length and a first profile and a second position in which the inflatable member has a second reduced length and a second reduced profile. Methods of use are disclosed.

A surgical instrument includes a first member defining an axis and including an end surface and a passageway. A second member is movably disposed within the passageway and includes a tip and a plurality of spaced apart markings. The second member is movable between a first configuration in which the tip extends parallel to the axis and a second configuration in which the tip extends transverse to the axis. The end surface is aligned with a first one of the markings when the second member is in the first configuration and the end surface is aligned with a second one of the markings when the second member is in the second configuration. Methods are disclosed.

Apparatus is provided that includes a surgical tool for use with solid particles and a physiological liquid solution. The surgical tool includes (a) a shaft unit, which is shaped so as to define a delivery lumen, and a distal opening, which is disposed within 10 mm of a distal end of the shaft unit, in fluid communication with the delivery lumen; (b) a composition source, which is coupled in fluid communication with the delivery lumen, and which is configured to provide a solid-liquid composition of the solid particles and the physiological liquid solution; and (c) a pump, which is configured to pump the solid-liquid composition through the distal opening via the delivery lumen.

Devices and methods for inserting bone cement into a patient during a surgical procedure. The methods may include inserting a tip of a nozzle at the desired location in the patient, such as an opening formed in a bone. An enlarged radial member may be positioned against the bone and covers the opening. Cement is moved through the nozzle and into the opening. The member may prevent escape of the cement from the opening. The nozzle may also be configured to facilitate insertion of the cement at the desired location within the patient.

A handle connectable to a screw-type mechanical drive component for transmitting to the latter a first torque comprises first connection means, defining a constraint axis, for the connection of the handle to the mechanical drive component, a ring nut to which a second torque is manually applicable, support means of the ring nut for rotatably supporting the latter around an axis of rotation coinciding, in use, with the constraint axis, second means for connecting the ring nut to the support means, for connecting/disconnecting the ring nut and the support means in a mechanical and selective way, so that the ring nut is kinematically connected to the support means when rotated around the axis of rotation with a second torque lower than a threshold value and kinematically disconnected from the same upon exceeding such a threshold value.

An implant for deployment in select locations or select tissue for regeneration of tissue is disclosed. The implant includes collagen and or other bio-resorbable materials, where the implant may also be used for therapy delivery. Additionally, the implant may include, or have blended in, an additive, such as an osteoinductive factor, for example biocompatible ceramics and glass.

A tool for insertion of an intervertebral insert into an intervertebral space is provided. The tool includes a shaft having a proximal end and a distal end. The distal end of the shaft is configured to be coupled to the intervertebral insert. The tool includes a tapered section located at the distal end of the shaft, the tapered section tapering toward the longitudinal axis of the shaft and away from the proximal end of the shaft. The tool further includes a recess formed in the tapered section, the recess configured to receive the intervertebral insert such that at least a portion of the intervertebral insert is located within the recess when the intervertebral insert is coupled to the shaft.

A surgical injection device includes at least one tubular element defining a passageway. The passageway is configured for disposal of a selected volume of an agent and an evacuator disposed within the passageway. An actuator is engageable with the evacuator to entirely expel the selected volume of the agent from the passageway to a selected site. Spinal constructs, implants, systems and methods are disclosed.

An introducer used to provide a route through which a catheter or other medical device is inserted so as to gain access to a subcutaneous vessel of a patient is disclosed. The introducer is configured so as to minimize the amount of force needed to enter and dilate a vessel, thus reducing trauma to the vessel and the patient. In one embodiment, an introducer is disclosed, comprising a sheath and a dilator. The sheath includes a tubular portion that defines a lumen. The dilator includes an elongate body and a tapered distal tip and is configured to be removably disposed within the lumen of the tubular portion of the sheath. The dilator elongate body defines a cylindrical recess proximally extending from the tapered distal tip. The cylindrical recess configured to receive therein the tubular portion of the sheath when the dilator is disposed within the tubular portion of the sheath.

An injection device for use in sacroiliac joint stabilization comprises an elongated conduit having a first end and a second end, where the first end includes a first opening and the second end includes a second opening; a carrier member couplable with the conduit and configured to accommodate a guidewire; a tool configured to be at least partially disposed in a bore of the conduit via the second opening, where the tool is configured to urge a hardening material in the bore toward the first end of the conduit; where the first opening of the conduit is configured to be angularly disposed relative to the second opening of the conduit such that the first end directs hardening material in a non-parallel direction relative to a longitudinal axis of the conduit.
