A connecting band for a highly flexible tissue-type heart valve having a stent with cusps and commissures that are permitted to move radially. The connecting band follows the cusps and commissures and extends outwardly. The valve is connected to the natural tissue along the undulating connecting band using conventional techniques, such as sutures. The connecting band may be a cloth-covered inner suture-permeable member and attaches to the underside of the valve at the cusps to provide support to the stent and to the outer side of the valve at the commissures. The connecting band includes commissure portions defining generally axial gaps that help permit flexing of the valve. The inner member may include one or more slits along the cusps to enhance flexibility. The inner member may further include a continuous outwardly projecting sewing ridge around its periphery which includes a series of ribs separated by grooves around the inflow edge of the cusps. The sewing ridge enables supra-annular implant of a valve constructed with the connecting band.

In a rod fixation system of the type used to treat various spinal conditions, the same fastener is used to lock both a polyaxial screw and a rod in position. A spinal correction device according to the invention, adapted for use with a rod and a polyaxial screw having a ball-shaped head and a threaded end, comprises a head-body and a cap. The head-body includes a lower internal cavity to receive the ball-shaped head of the screw, an upper bore to receive a fixation rod therethrough, and an upper end configured to receive the cap. The head-body and the cap are configured such that a first rotation of the cap locks the polyaxial screw in position, and a second rotation of the cap locks the rod in position. In the preferred embodiment, the head-body includes one or more gaps to facilitate flexion of the head-body as a rotational torque is placed on the cap. The gap or gaps may be horizontal, vertical or other angles relative to the axis of the entrapped rod.

A flexible support frame for a prosthetic heart valve having commissure tips that are shaped to even out stresses imposed during use. The support frame is an elongated wire-like element formed by a plurality, typically three, of arcuate cusp regions on an inflow end alternating with the same number of commissures terminating in tips on an outflow end. The commissure tips are elongated relative to more simple shapes. The commissure tips may be shaped with a complex curve having two enlarged convex flexure portions separated by a concave bridge portion at the midpoint of the commissure tip. The support frame may be fabricated by separating a two-dimensional blank from a sheet and then converting the blank into a three-dimensional support frame shape. The cross-sectional thickness of the support frame may be variable, such as by adjusting the thickness of the pattern of the two-dimensional blank in the sheet. Desirably, the radial thickness remains constant while the circumferential dimension varies with a maximum located at the commissure tips.

A colonic overtube for maintaining a sigmoid colon in a straightened configuration has a proximal end for location externally of a colon, and a distal end for insertion into a colon. A colonoscope lumen extends through the overtube to facilitate passing the overtube over a colonoscope. The overtube has a convoluted corrugation which extends along the entire length of the overtube from the proximal end to the distal end. The corrugated configuration of the overtube provides the overtube with laterally flexibility so that the overtube may flex substantially without kinking during advancement of the overtube through a colon. A flexible seal, in the form of a tubular silicone sheath of film material, is provided at the distal end of the overtube for sealing between the overtube and a colonoscope extending through the colonoscope lumen. The flexible nature of the seal enables the seal to adapt itself to the size of the colonoscope extending through the colonoscope lumen to achieve a secure, effective seal between the overtube and a colonoscope regardless of the colonoscope size.

A fastener for fastening a golf ball cleaning device to clothing wherein the fastener has a base portion secured to the back surface of the golf ball cleaning device and a pair of resilient spaced retaining legs extending from the base portion parallel with and spaced from the back surface of the golf ball cleaning device. The legs form a slot for insertion and retention therein of a button having an extent of clothing thereover.

According to one embodiment, an orthopedic support for supporting a portion of a wearer's anatomy is provided. For example, the orthopedic support may be an ankle brace comprising a sheet of flexible material configured to at least partially enclose a wearer's ankle and a splint coupled to the sheet of material. The splint is configured to be positioned on a medial side of the wearer's ankle when the sheet of material is secured on the wearer's ankle and includes an undulating profile configured to conform to at least a portion of the medial side of the wearer's ankle and resist inversion of the ankle

An adjustable holographic gun sight has a base and a carrier pivotally connected to the base. An adjustment mechanism may be adapted to pivot the carrier with respect to the base. A pair of dropouts connects the carrier to the base and the dropouts allow the carrier to pivot with respect to the base. The dropouts may be mounted to an external portion of the carrier and the base thereby provides for external adjustment of the gun sight.

A fastening device for fixing a member to be fixed to a fixing member through a screw, the fastening device includes: a top plate portion; and a pair of leg piece portions respectively suspended from the two side edges of the top plate portion, wherein the top plate portion includes two pairs of first elastic securing pieces disposed opposed to each other for defining a first screw hole formed in the screw, and two pairs of regulating pieces respectively interposed between the first elastic securing pieces for defining a first guide hole having a diameter larger than the first screw hole.

A vise and base system is disclosed. The vise includes a stationary jaw, a frame with a frame perimeter wall and a moveable jaw, the stationary jaw being fixed to the frame, and the moveable jaw that is movable along the frame. The vise cooperates with a hollow base that includes a first recessed area that is adapted for mating with the frame perimeter wall and a second recessed area that is adapted for mating with the stationary jaw. The base also includes a base panel that is attached to the base perimeter wall and a layer of flexible high friction material that is attached to the base panel, such that the base can support the vise in a generally horizontal position and in a generally vertical position.

A weatherstrip assembly for a vehicle. The assembly includes a body having a base and first and second legs which define a channel. The body includes an interior base surface, a first interior leg surface, and a second interior leg surface disposed within the channel. The assembly includes at least one sealing lip having an abutment surface and a wearstrip disposed along at least one of the interior base surface, the first and second interior leg surfaces, and the abutment surface and formed of a thermoplastic polyethylene material. The wearstrip has a plurality of alternating wear sections and gaps that define a series of alternating semi-rigid and flexible sections, respectively, with each wear section having first and second surfaces. The first surface of one of the wear sections and the second surface of an adjacent wear section face each other to define the gap.

An article of footwear is provided including at least an upper, an outsole with protrusions, and a segmented toe region. The protrusions underneath the outsole provide the grip, traction, and anti-slipping features desirable in certain field sports or other activities. The segmented toe region comprises a plurality of compartments, providing autonomous, mobility, and flexibility for individual toes.
