摘要： The present disclosure provides a bioresorbable foam closure device for trans-nasally closing an opening in a base of a skull. The closure device comprises a phase-separated polymer. The device includes a stem portion having a proximal end and a distal end, and a head portion at the distal end of the stem portion. The closure device is deformed from a free shape to a constricted shape, inserted through a nasal cavity and into the opening, and released to at least partially revert back to the free shape such that the stem portion fills the opening and the head portion abuts cranium and dura to secure the closure device in position and seal the opening.

摘要： A bone fastener includes a head, and a screw portion extends from the head. The screw portion includes a shaft and a thread extending along and about the shaft. The thread has a height extending from a root to a tip thereof. The thread also has first and second portions disposed between the root and the tip. The second portion has a porous structure configured to promote bone ingrowth and has a porosity greater than that of the first portion.

摘要： An implant delivery system comprises an elongate tubular member having a lumen, a tubular implant coaxially disposed within the lumen of the elongate tubular member, and a delivery assembly having a distal portion coaxially disposed within tubular implant. The delivery assembly comprises a delivery wire, an engaging bumper fixedly coupled to the delivery wire, a stopper bumper fixedly coupled to the delivery wire, and a floating element slidably coupled around the delivery wire and disposed between the bumpers, thereby limiting linear translation of the floating element therebetween. The floating element has an engaging portion configured to engage the engaging bumper when the delivery wire is axially translated relative to the elongate member in a first direction. The floating element is configured to radially expand outward to frictionally engage the implant when the engaging portion of the floating element engages the engaging bumper.

摘要： Vaso-occlusive apparatuses, including implants, and methods of using them to treat aneurysms. For example, described herein are expandable vaso-occlusive implants that include one or more soft and expandable braided member coupled to a pushable member such as a coil that maybe inserted and retrieved from within an aneurism using a delivery catheter. In particular, the expandable implants described herein are configured to allow relatively soft and elongate implants to be pushed out of a cannula without binding up within the cannula.

摘要： An irrigation sleeve, for use with a surgical system that comprises an irrigation source and a surgical tool having a tube to support a cutting accessory having a head, in turn comprises a body extending between proximal and distal ends. A first lumen formed in the body receives the tube. The head is adjacent the distal end. A second lumen formed in the body is spaced from the first lumen and comprises proximal and distal regions thereof. The proximal region of the second lumen extends from an inlet for fluid communication with the source, to a transition. The distal region of the second lumen is spaced out of fluid communication with the first lumen and extends from the transition to an outlet to direct fluid adjacent to the head.

摘要： The invention relates, generally, to porous absorbent materials which are suitable for packing antrums or other cavities of the human or animal body. More particularly, it relates to hydrophilic biodegradable foams, which may be used e.g. in the form of a plug or tampon, for instance for controlling bleeding, wound closure, prevent tissue adhesion and/or support tissue regeneration. The invention provides an absorbent foam, suitable for packing antrums or other cavities of the human or animal body, comprising a biodegradable synthetic polymer, which polymer preferably comprises —C(O)—O— groups in the backbone of the polymer, for instance polyurethane and/or polyester units combined with polyethers.

摘要： An elongate embolectomy device having a radially constrained configuration and a radially expanded configuration, the embolectomy device being formed out of a plurality of elongate clot engaging structures, each clot engaging structure comprising a plurality of interconnected struts forming an open cell pattern, wherein, when the embolectomy device is in the radially expanded configuration, the clot engaging structures each have a semi-tubular arcuate profile, including a convex face and an concave face facing opposite the convex face, extending along a length of the embolectomy device, the clot engaging structures being longitudinally disposed relative to each other such that the concave faces are facing radially outward, and the convex surfaces are facing radially inward, respectively, relative to a longitudinal axis of the embolectomy device.

摘要： An external fixation system includes first and second fixation members having first and second pluralities of mounting holes, respectively. The first and second plurality of holes are configured to receive first and second ends of a plurality of struts, each strut having a default or initial mounting position. A simulation of the correction may be performed with the struts in the default positions, but it may be determined that the correction is not achievable. Additional simulations of the correction may be performed with the ends of the struts in different mounting positions to determine if other mounting positions of the struts allow the correction to be completed. During the correction, if one of the struts reaches a maximum length, it may be disconnected and reconnected to a different mounting hole so that, after being reconnected, the strut may be further increased in length to continue the correction.

摘要： A cutting assembly including a grip. A tube assembly includes an outer tube, and an inner tube configured to be rotated by a motor of a drive assembly. The grip includes a nose portion defining an aperture from which the tube assembly extends distally, and an intermediate portion forming with the nose portion an open area ledge. The open area ledge may be sized to receive a connecting hub configured to be removably coupled to a housing of the drive assembly. A coupling member of the connecting hub may include a flange disposed within the open area ledge. A manually movable member is configured to rotate the outer tube about a longitudinal axis. The manually movable member may be positioned between the nose portion and the flange. The manually movable member may include a gripping surface positioned radially outwardly relative to sides of the nose portion.
