摘要： A suture guide and fastener includes a suture retaining device which orients and secures one or more suture strands therein and receives energy applied to the strands to bond them within the suture retaining device. The fastener becomes integral with the bonded sutures and may be made of a material similar to the suture material, which melts upon the application of energy thereto. Alternatively, the fastener may be made of a different material which remains intact upon application of bonding energy to the sutures. When ultrasonic energy is applied, the fastener may function as a stationary ultrasonic weld anvil. Other types of energy, such as laser, thermal or chemical, may be applied to the suture strands to effect bonding.

摘要： A fusible collar (1) for securing sutures (13) without knots, and for securi ng living tissular structures together without sutures. The fusible collar (1) is made of a compressible material, and is formed generally in a "c" shape whic h can be compressed into an "o" shape, with portions of the collar overlapping around the structures to be secured. Energy is applied to the overlapping portions of the collar (1) to cause localized heating and plastic flow so as to fuse the overlapped portions together. The collar (1) can include one or more energy directors (14) on a contact surface to direct, and focus energy to particular regions so as to effect collar to suture welding.

摘要： A prosthetic cardiac valve assembly (10) for sutureless implantation in a patient. The assembly (10) includes a generally disk-shaped valve annulus element (12), and one or more generally disk-shaped retainer elements (16). The elements (12, 16) are adapted for mutual engagement, and for engagement with a host tissue region (18) so as to fix a portion of the host tissue (18) between them in a sutureless bond. Ultrasonic or thermal energy is applied to one or more of the elements to bond them together. Either the valve annulus element (12) or the retainer element (16) includes a plurality of projections (20), and the corresponding element includes a corresponding plurality of apertures (14) for receiving the projections, thus providing for mutual physical engagement. The valve annulus element (12) can include a plurality of valve leaflets (14) which open and close in response to fluid pressure differentials across them. Various insertion devices for the assembly (10) are designed to facilitate insertion of the elements in the heart through a relatively small incision. The elements (12, 16) can be implanted, assembled and bonded together in situ around the host tissue (18).

摘要： A fused loop of an elongated material, such as a surgical suture, and apparatus for making the loop are described. Portions of one or more segments of elongated material may he fused in an ultrasonic welding process to form a welded joint. Multiple materials each with a different melting point may be used for one or more fibers within the elongated material The elongated material may include a sheath, which may be used to protect a core within the elongated material. A fused region of the fused loop may be formed when a material with a lower melting temperature, compared to one or more other materials in the elongated material, is caused to melt. A related ultrasonic welding apparatus may include a temperature sensor for control of the welding process.

摘要： A single-piece soft tissue fixation device includes an elongated element terminating in a tip at one end and a receptacle at the other end which bond with each other in a welded joint. The device is made of a heat-bondable, biocompatible material that can be ultrasonically or thermally welded. The tip and receptacle of the device can be textured or contoured or otherwise complementarily configured to promote mutual engagement prior to and during bonding. The tip can include a needle or needle-like extension for penetrating tissue. The device may be at least partially resorbable in living tissue.
