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.

An irrigation system for use in endoscopic procedures for maintaining and controlling flow of irrigation fluid to an internal body irrigation site. The system includes a tubing set comprising inflow and outflow lines and a cassette, and an fluid control module comprising a race and a pumping mechanism that squeezes the inflow line of the tubing set against the race to pump fluid to the irrigation site. The cassette includes a through opening exposing a portion of the inflow line to the race and pumping mechanism so that the cassette merely holds the inflow line in alignment with the pumping mechanism but is not required to resist the compressive force of the pumping mechanism. The cassette may include a second through opening exposing a portion of the outflow line to a valve mechanism to regulate pressure independently of the pump mechanism, and rib-or-groove alignment mechanism to align the inflow line with the pumping mechanism and the outflow line with the valve mechanism.

A fused loop of an elongated material, such as a surgical suture, and apparatus for making the loop. Portions of one or more segments to be joined together are fused in a welding process to form a welded joint. The shear area of the fused portion of the joint determines the strength of the joint and is thus preferably relatively large. Various configurations for the welding apparatus facilitate the creation of relatively large fused portions of the joint by maximizing contact between at least one of the welding members of the apparatus and at least one of the segments to be joined.

An irrigation system including a pump that regulates the supply of fluid to an endoscopic surgical site, and a tubing set for supplying the fluid. The tubing set comprises an inflow line for supplying fluid to the surgical site, and an outflow line for draining fluid from the surgical site. At least one of the inflow and outflow lines includes an expandable compliant tubing segment that expands to accommodate changes in the rate of fluid flow through the surgical site to reduce variations in fluid pressure in the surgical site. The fluid volume within the compliant tubing segment increases in response to increasing fluid pressure within the compliant tubing segment. The system is particularly designed for use in small joint arthroscopy (e. g. , of the wrist) where the fluid volume in the surgical site is relatively small.

A device () for treatment of obesity of a patient comprises an annular element () having a relatively large outer boundary and a relatively small inner boundary, and an elongated flexible tube () extending from the relatively small inner boundary of the annular element to a distal end. The relatively large outer boundary is adapted to be attached to an inner wall of a stomach () of a patient, such that the annular element divides the stomach () into two chambers, an esophagus-end chamber close to an esophagus of the patient, and a pylorus-end chamber close to a pylorus of the patient. The invention also provides a method for treatment of obesity of a patient which includes inserting an annular element having a relatively large outer boundary and a relatively small inner boundary into a stomach of the patient, and attaching the relatively large outer boundary of the annular element to an inner circumference of the stomach of the patient.

A fused construct including a first end formed into a fused loop, a second end formed into a fused loop, and an intermediate part extending between the loops, wherein the loops and the intermediate part include at least one segment of elongated material. Each of the loops includes a joint region having overlapped portions of the elongated material, and a relatively thin layer of fused material from the overlapped portions. The fused material is characterized by a low degree of molecular orientation in the direction of a principal axis of the elongated material, and the overlapped portions are characterized by a high degree of molecular orientation in the direction of the principal axis.

An improved gastric bypass prosthetic (GBP) device and an improved GBP fixation device, as well as a GBP kit for the surgical treatment of obesity. In one form, a gastric bypass prosthetic (GBP) device of the invention includes a optional flexible tube extending along a central axis from a proximal end to a distal end, and having a tubular tissue fixation portion at or near said proximal end. The tissue fixation portion extends along the central axis between a proximal end and a distal end of the tissue fixation portion, and has an annular outer surface between the proximal end and the distal end of the tissue fixation portion.
