A graft or prosthetic element suitable, e.g., for replacing a tendon or ligament is fastened in a bone tunnel or blind opening with the aid of a fastener. In a first step, the graft or prosthetic element is press-fitted in the tunnel or opening by forcing the fastener into the opening or by positioning the fastener in the opening and then expanding it, wherein the fastener is in contact with the graft or prosthetic element and with the bone wall of the tunnel or blind opening. In a second step, the fastener is anchored in the bone wall of the tunnel or blind opening with the aid of a liquefiable material which is liquefied in the vicinity of the bone wall where it is in contact with the fastener and by making the liquefied material penetrate into the bone wall.

A surgical instrument includes an outer housing shell defining a cavity, the outer housing shell defining an upper outer housing half and a lower outer housing half, wherein the upper outer housing half defines a longitudinal axis and an instrument module selectively insertable into the cavity of the outer housing shell. The instrument module includes an inner housing shell, at least one motor disposed within the inner housing shell, a control board being in electrical communication with the at least one motor and an energy source being in electrical communication with the at least one motor and the control board. The instrument module is inserted into the cavity of the outer housing shell in such a manner that the operative axis of the at least one motor is substantially parallel to the longitudinal axis of the upper outer housing half.

According to the aspect of the present disclosure, various forms of medical 3D threads produced using ultrasonic waves are provided. Thus, we can expect high satisfaction with the medical 3D threads having high tensile strength and holding power. The medical 3D threads can be produced to have about twice as many barbs as conventional medical threads and can be produced using ultrasonic waves without damaging yarn or making knots. Thus, it is possible to overcome the cause of a decrease in physical strength.

An endoscopic surgical clip applier includes an endoscopic assembly and a handle assembly. The handle assembly includes a housing, a trigger, a drive bar, and a ratchet assembly. The ratchet assembly includes a first rack, a second rack, a pawl housing engageable with the first rack, and a second pawl engageable with the second rack. In a first position, the pawl housing is in registration with the first rack to prohibit reversal of a direction of movement of the trigger until the pawl housing is disposed beyond a proximal end or a distal end of the first rack. In a second position, the pawl housing is out of registration with the first rack to permit reversal of the movement of the trigger after the second pawl is disposed distally beyond a distal end of the second rack or proximally beyond a proximal end of the second rack.

An apparatus for forming a weld between a first portion of a biocompatible conductive thermoplastic material and a second portion of a biocompatible conductive thermoplastic material comprises a first electrode, a second electrode, and a structure for holding said first and second electrodes in opposition to one other with a space therebetween for receiving said first portion and said second portion in contact with one another. The structure is electrically non-conductive and an electrical circuit comprising a power source and a switch arranged such that closure of said switch applies a voltage potential across said first electrode and said second electrode so as to generate heat via electrical resistance, the heat being sufficient to melt regions of said first and second portions.

Disclosed herein are an implant with an attachment feature and a method for attaching to the same. The implant may include a cavity with a porous layer disposed within a non-porous layer wherein the non-porous layer defines a chamber. The chamber may receive and confine liquefiable material and direct liquefiable material to permeate through the porous layer. A method of attaching a device to the implant may include liquefying a liquefiable portion of the device and allowing the liquefied material to interdigitate with the second layer and then solidify to prevent pullout.

Particular embodiments disclosed herein provide a surgical instrument comprising a device having a proximal end and a functional end configured to be inserted into a body part, an assembly having a proximal end and a distal end, a shaft coupled to the proximal end of the assembly, the shaft having a shaft housing, a bearing positioned around the assembly, wherein the bearing is configured to slide over the assembly, a hub having a sleeve tube. The basket comprises a plurality of grooved levers, each grooved lever having a proximal end received by the shaft housing and a distal end coupled to a tip of the basket, wherein compressing one or more of the plurality of grooved levers moves the bearing and the hub relative to the shaft and toward the functional end of the device, causing the sleeve tube to transition the device from the deactivated state to an activated state.

A balloon catheter including a heating element disposed about a portion of an outer surface of a catheter shaft; a balloon mounted about the outer surface of the catheter shaft to coincide with the heating element; and thermally expandable material disposed inside the mounted balloon. The balloon catheter eliminating the need for pressurized liquid inflation media to be dispensed into/expelled from the balloon in order to inflate/deflate, respectively, the balloon.

Tissue fasteners carried on a tissue piercing deployment wire fasten tissue layers of a mammalian body together include a first member, a second member, and a connecting member extending between the first and second members. One of the first and second members has a configuration alterable by a deployment wire to permit release of the fastener from the deployment wire after deployment and without causing excessive tissue trauma.

This disclosure relates to a medical device. The medical device comprises a first and a second component. The first component comprises a first portion having a first handle part and a second portion having a grip. The second component is linked to the first component and is configured to be in communication with the first component to be actuated from an open to a closed position. The second component defines a third portion and a fourth portion, the third portion defining a second handle part and the fourth portion defining a second grip that is configured to grip a tissue in combination with the first grip portion of the first component. In certain embodiments, the first component or second component comprises a substantially straight member attached distally from the grip.
