A medical device includes a balloon expanded scaffold crimped to a catheter having a balloon. The scaffold has a network of rings formed by struts connected at crowns and links connecting adjacent rings. The scaffold is crimped to the balloon by a process that includes using protective polymer sheaths or sheets during crimping, and adjusting the sheaths or sheets during the crimping to avoid or minimize interference between the polymer material and scaffold struts as the scaffold is reduced in size.

A suture and a suture retainer are positioned relative to body tissue. Ultrasonic vibratory energy is utilized to heat the suture retainer and effect a bonding of portions of the suture retainer to each other and/or to the suture. Portions of the body tissue may be pressed into linear apposition with each other and held in place by cooperation between the suture and the suture retainer. The suture retainer may include one or more portions between which the suture extends. The suture retainer may include sections which have surface areas which are bonded together. If desired, the suture may be wrapped around one of the sections of the suture retainer. The suture retainer may be formed with a recess in which the suture is received. If desired, the suture retainer may be omitted and the sections of the suture bonded to each other.

A method for locating a material having thermoplastic properties in pores of bone tissue includes providing a pin having the material having thermoplastic properties and a core, wherein the material having thermoplastic properties is arranged on the circumferential surface of the core constituting an outer region of the pin. An opening is provided in the bone tissue, and the pin is positioned at least partly in the opening. The outer region of the pin is then impinged with mechanical vibration energy for a time sufficient for liquefying at least part of the material having thermoplastic properties, and, in a liquefied state, pressing it into the pores of the bone tissue surrounding the opening. The vibration energy is stopped for a time sufficient for re-solidification of the liquefied material, and then the core is removed.

A wet wipe pad designed to be connected or attached to floor mop heads or other cleaning tool handle that utilize a hook-and-loop mechanism for attaching the wipe pad thereto. The wipe pad can be made of multi layers of material that may include a cleaning layer ultrasonically welded to an attachment layer having an absorption layer disposed between the cleaning layer and the attachment layer. Alternatively, the wipe pad can be made from a single layer of material that can attach on one side thereof to the mop head or other cleaning tool handle, which also provides a cleaning surface on the other side of the single layer of material. The wipe pad of the invention may also be constructed from two layers of material that include a cleaning layer ultrasonically welded to an attachment layer. Regardless of the number of layers used in the wipe pad of the invention, the wipe pad is configured with at least one linking ribbon or tape strip of non-looped straight-line fibers extending along the length of the attachment layer and which forms the means or mechanism for releasably securing to hooks disposed on the mop head. The wipe pad, including its layer(s) and the linking ribbon or tape strip is constructed of materials that are compostable and biodegradable, making it an environmentally friendly product.
