A method for forming a surgical snare, the method comprising: providing a plurality of filaments; braiding the plurality of filaments together so as to form a braided tubular construct comprising: a proximal tube having an open proximal end, an open distal end, and a proximal tube lumen extending there between; a distal tube having an open proximal end, an open distal end, and a distal tube lumen extending there between; and a loop region disposed between the distal end of the proximal tube and the proximal end of the distal tube, the loop region comprising at least one loop structure, the at least one loop structure comprising at least three of the plurality of filaments braided together; inserting the distal end of the distal tube into the open distal end of the proximal tube and into the proximal tube lumen such that (i) the distal tube is disposed in the proximal tube lumen such that the at least one loop structure extends distally of the distal end of the proximal tube in the form of at least one loop, and (ii) the distal tube lumen extends from a point located distal to the proximal end of the proximal tube to the at least one loop.

Systems, devices, and methods for stabilization of bones and/or joints are disclosed. A medical implant may be inserted into a treatment site, such as an interspinous process space. The implant may have an outer body, an inner body coupled to the outer body, distal wings coupled to the inner body, proximal wings coupled to the outer body, and a threaded screw coupled to the inner body and outer body. The threaded screw may be configured to couple to a driver head of an insertion tool and the outer body may be configured to couple to an attachment member of an insertion tool. Actuating the insertion tool may actuate the threaded screw to thereby transition the proximal wings and the distal wings from a closed configuration to a deployed configuration, and from a deployed configuration to a clamped configuration.

A surgical apparatus comprising: a mechanism that is configured to perform an operational motion of the surgical apparatus; and at least one transformation member having an original shape and a deformed shape, the at least one transformation member connecting the mechanism together, when the at least one transformation member is in the deformed shape so that the mechanism is capable of performing the operational motion; and wherein after the transformation member is subject a transition temperature, the at least one transformation member changes from the deformed shape to the original shape and disengages a portion of the mechanism so that the mechanism is prevented from performing the operational motion.

An intramedullary fixation device used in bone fixation and stabilization on a patient includes a longitudinally extending rigid body, a distal head disposed at a distal end of the body and sized for insertion into an intramedullary canal of a phalanx of the patient, the distal head having a central core portion and a plurality of extending distal wings radially projecting from the central core portion. A proximal head at a proximal end of the body is sized for insertion into an intramedullary canal of a phalanx of the patient. It has a central core portion and a plurality of proximal wings extending radially outwardly from the central core portion.

A cutting head for use with an intramedullary reamer is described. The reamer cutting head is of a unitary body construction that comprises a conically-shaped body having a bone cutting portion spaced from a barrel portion for attachment to a drive shaft. The bone cutting portion comprises a plurality of blades having a tissue cutting edge that outwardly extends from the cylindrical body. The plurality of blades is positioned about the cutting head in a spaced apart manner. The various plurality of blades are arranged at prescribed angular relationship that increases cutting efficiency and debris removal, thereby reducing reactive torque, axial loading, and head pressure during a surgical procedure.

An endoscopic tissue resecting system that includes a reciprocating rotary surgical instrument for cutting tissue that includes a planetary gear assembly to vary rotational speed. A method of cutting and detaching tissue includes positioning an outer member such that tissue is located within a window in the outer member, engaging the tissue with an inner member, and simultaneously rotating at an increased speed relative to a rotary driver and translating the inner member to cut the tissue. A tangential cutting force is applied to the tissue with the inner member to mechanically cut and detach the tissue.

A method of, and apparatus for, fixing an implant with respect to first and second bone parts at a joint. The method includes the steps of: obtaining a guide structure having a body with a first discrete projecting referencing arm; placing the guide structure in an operative position by directing the first discrete projecting referencing arm through a joint capsule to against a joint surface on the first bone part to establish a referencing location relative to the joint surface; with the guide structure in the operative position, using the guide structure to facilitate alignment of the implant in a desired seated position with respect to the first bone part; and thereafter fixing the implant in the desired seated position.

A system includes a sheath comprising a handle and a catheter tube, an intralumenal device with a shaft of a predetermined geometry and configured to traverse through the handle and the catheter tube, and a sensor assembly disposed approximate the handle and configured to determine a length of insertion of the intralumenal device within the sheath to thereby determine a position of a distal end of the shaft. Also, a method for visualizing a distal end of an intralumenal device, comprising determining a position of a distal portion of the sheath within a body of a patient, determining a length of insertion of a shaft configured with a predetermine geometry within a sheath, determining a position of a distal end of the shaft within the body of the patient based at least in part on the length of insertion of the shaft within the sheath, the predetermined geometry of the shaft, and the position of the distal portion of the sheath, and providing a graphical representation of the position of the distal end of the shaft within the body of the patient.

Actuating the insertion tool may actuate the threaded screw to thereby transition the proximal wings and the distal wings from a closed configuration to a deployed configuration, and from a deployed configuration to a clamped configuration.

Proposed is an anti-migration stent which expands a lesion area occurring in a lumen and is prevented from migrating, is deformed to fit the lumen of a curved shape, and can be easily removed from the lumen. More specifically, the anti-migration stent includes a first stent including a first cylindrical body, a first film part, and a second film part, and a second stent including a second cylindrical body, a connection part formed by having a diameter decreasing at one side of the second cylindrical body, and a third film part made of silicone formed on the second cylindrical body and the connection part, wherein after the second stent is fitted over one side of the first stent, the one side of the first stent and the connection part are connected to each other, and the second stent is held in the lumen.
