Heart valve prosthesis, comprising a ring-shaped supporting structure (3) to be anchored at the valve annulus, and a valve leaflet (5) supported by the supporting structure. The supporting structure comprises a support wall portion (31), at which a root end (51) of the valve leaflet is connected, and a complementary wall portion (32) opposite the support wall portion, which supports a coaptation surface (33) adapted to be sealingly engaged by a free end (52) of the valve leaflet (5), and extending in a direction parallel to the direction of movement of the free end (52) of the valve leaflet (5) at the coaptation surface (33). The free end of the valve leaflet (5) is connected to the support wall portion or to the complementary wall portion by means of a traction member (55), dimensioned in such a way that the free end (52) of the valve leaflet (5) is stopped at the coaptation surface.

A stent-graft, including a generally tubular vascular graft of biocompatible material, and a plurality of bio-resorbable discrete annular members spaced apart along a longitudinal axis of the vascular graft and attached thereto.

An example collar includes a strap, a removable buckle slidable along the strap, and at least one removable leash attachment. The leash attachment includes a strap-receiving portion with a thickness approximately equal to a thickness of the strap such that the strap is receivable in the strap-receiving portion in a biased fit and the leash attachment is fixable at a location along the strap. Another example collar and a method of assembling a collar are also disclosed.

A trimmer head for use with either clockwise or counterclockwise trimmer heads, including the use of a bidirectionally dispensing spool. Various locations of passages straight through the trimmer head and spool are shown along with various locations of components of the ratcheting mechanism to allow for winding of the trimmer line on the trimmer head and for limiting the amount of line dispensed during bumping of the trimmer head knob on the ground. Additionally, an extended funnel into the passage can be provided to facilitate entrance of trimmer line into the funnel even when the line is not perfectly straight. Also, spokes can be used in place of the flanges of the spool to save material and cost, while still providing a guide and barrier between the line store areas.

Aspects of the present invention provide a theft-resistant cable clamp that increases the time and effort required to remove the cable from the irrigation equipment, thereby deterring thieves As the extensions that protrude from the cable-reception loop are forced together, the walls of the cable-reception loop compress against the cable. Openings in the extensions on the cable clamp allow the cable clamp to fit over a component of the irrigation equipment. A plurality of teeth can protrude from the perimeter of an opening to grip the exterior of the component. A coupler or other component may have a groove into which the teeth engage when the cable clamp is in a final location on the component.

A method of delivering a therapeutic device to a treatment area of a body lumen, the therapeutic device including a) a delivery member possessing at least one attachment part and b) a treatment membrane, includes wrapping the treatment membrane on the delivery member, attaching the treatment membrane to the attachment part of the delivery member, and moving the delivery member toward the treatment area, detaching the treatment membrane from the delivery member, and withdrawing the delivery member from the body lumen.

A trimmer head spool for a vegetation trimmer machine. The spool includes a hub that defines a bore and has at least one flange or a plurality of spokes extending radially outwardly therefrom. A trimmer line conduit defined in the spool includes a first funnel defined in a first region of the flange or spokes and a second funnel defined in a second region of the flange or spokes. A non-radial guide channel is in fluid communication with the first and second funnels. The non-radial guide channel spans the hub's bore and does not extend through a central axis of the spool about which the spool is rotatable. The non-radial guide channel may be provided on a module that is selectively inserted into the bore and aligned with the first and second funnels. In other embodiments the entire trimmer line conduit is integrally formed in the spool.
