Staple cartridge assemblies for use with surgical stapling instruments and methods for manufacturing the same are provided. Scaffolds for use with a surgical staple cartridge and methods for manufacturing the same are also provided.

This document describes bone matter collection devices and methods for their use. For example, longitudinally extendable/retractable spirally wound, conically-shaped bone matter collection/harvesting devices are described. In some implementations, such bone matter collection devices can be attachable with and detachable from bone drill bits. In some implementations, bone chips generated by bone drilling are collected in such a bone matter collection device while the bone matter collection device is detachably coupled to the bone drill bit, and the collected bone chips can be used for bone grafting and other purposes.

An endcap for engaging a proximal end of an intramedullary nail. The endcap includes a body extending from a first end to a second end and configured to engage a channel of an intramedullary nail. The endcap also includes a head portion at the first end of the body. The head portion includes a recess sized and shaped to receive a driving element of a drive shaft. The recess includes elastic tabs extending radially toward a central axis of the recess to engage and retain a driving element received therein.

Provided herein are novel devices for the formation of arteriovenous fistulas, which may aid subjects in need of hemodialysis. The novel devices are provided in a non-surgical procedure, greatly decreasing the cost and increasing the convenience of placing an arteriovenous fistula. The devices are atraumatic, and consist of a sutureless anastomosis device and conduit. Methods and tools for placing the devices in vivo are disclosed, including a magnetic-assisted method.

A ligation device that includes a clip device including an openable arm, a connector connected to the clip device and is able to be released from the connector, a wire connected to the connector and configured to operate the clip device, and a pipe including an opening into which the wire is inserted. An inner diameter of the opening is smaller than a dimension in a diameter direction of the connector in a first state in which the connector and the clip device are connected with each other, and the inner diameter of the opening decreases towards a proximal end side of the pipe and is larger than the dimension of the connector in a second state in which the connector and the clip device are unconnected with each other.

An endoscopy instrument is configured to be adjustable between a retracted position and an extended position. The endoscopy instrument includes a snare forming a loop extending from a proximate end to a distal end and a plurality of basket wires. Each of the basket wires includes a proximate end coupled to the proximate end of the snare and a distal end coupled to the distal end of the snare. The snare and the plurality of the basket wires cooperate to form a basket portion configured to contract when the endoscopy instrument is adjusted from the extended position towards the retracted position during entry of the basket portion into a tubular member. The contracting of the basket portion aids in grasping an object in need of retrieval from a patient.

An assembly for retracting soft tissue in a surgical incision is provided, the assembly including a supporting member having first and second ends; a retractor blade having a first distal end and a second proximal end retained at the first end of the support member; a retaining arm which co-operates with the support member and receives and supports a clamping assembly; and an adjusting assembly which engages the support member and allows the clamping assembly to advance and retract relative to the retractor blade.

In various embodiments, a layer of material can comprise a body, a proximal end portion, and a distal end portion. The proximal end portion can be releasably secured to a staple cartridge of a surgical end effector, and the distal end portion can be releasably secured to an anvil of the surgical end effector. The layer of material can comprise a tissue thickness compensator.

The invention comprises a fusion implant system for a generally u-shaped bone staple in which the staple is provided on a storage block with the two side legs in an unsplayed position, and an inserter having two triangular shaped pivoting handles has detachable tips that engage the staple on the storage block such that when the handles are aligned one over the other in a congruent position, the tips force the side legs into a splayed configuration at 90° and a sliding block holds the handles in this position to allow the staple to removed from the storage block and tamped using the inserter handles into respective bone.

A magnetic marker for marking a site in tissue in the body. In one embodiment, the marker comprises a magnetic metallic glass. In another embodiment, the marker is in a non-spherical configuration having an anisotropy ratio less than 9. In yet another embodiment, the marker is in a non-spherical configuration having an anisotropy ratio less than 6. In yet another embodiment, the marker is in a non-spherical configuration having an anisotropy ratio less than 3.
