An excisional biopsy and delivery device may comprise one or more rotating, penetrating and cutting rod elements. The rod elements may be configured to advance from a stored and confined first position and rotate about an axis, while being simultaneously revolved about a central axis. The rod elements may then assume a second released and expanded configuration that is operative to cut around and surround target tissue. In this manner, the rod elements are operative to move through the surrounding tissue to create a volume of revolution and to sever and capture the target tissue contained within the volume of revolution from the surrounding tissue. The severed and captured volume of revolution containing the target issue may then be removed.

A biopsy device for acquiring a tissue sample is disclosed. The biopsy device comprises a tissue-engaging outer element, a handle and a trocar. Multiple tissue samples may be collected.

A biopsy device includes a body, a needle, a cutter, an analysis area, a valve, and a tissue sample holder. The cutter is movable relative to the needle and in communication with the needle for transporting tissue samples. The analysis area is disposed proximally of the cutter and in communication with the needle to receive a tissue sample cut by the cutter for analysis by a user. The valve is disposed proximally of the analysis area and configured to alternate between an open configuration and a closed configuration. The tissue sample holder is disposed proximally of the valve and fixedly attached to the body. The valve is configured to permit analysis of the sample disposed in the analysis area when the valve is in the closed configuration and to permit the tissue sample to be passed into the tissue sample holder when the valve is in the open configuration configuration.

A biopsy kit, comprising a penetration rod having a distal end portion, a cutting tube enclosing the penetration rod, comprising circumventing cutting means. The cutting tube is extendable from the penetration rod for cutting and enclosing a piece of target tissue, and a cutting device is extendable from the penetration rod and comprises distal cutting means for cutting off the piece of target tissue from the body. A method: penetrating tissue using a penetration rod; upon reaching the tissue to be removed, carrying out the following two steps in any consecutive order: extending a cutting device from the penetration rod to penetrate the target tissue, extending a cutting tube to cut out and enclose the target tissue; and additionally cutting off the piece of target tissue using a cutting means of the cutting device after extending the cutting device either before or after extending the cutting tube.

A biopsy device includes an ultrasonic probe, a display, an actuator, and a needle assembly. The display is associated with the ultrasonic probe, and the ultrasonic probe is configured to send a signal to the display to generate an image on the display. The needle assembly is coupled to the actuator and is at least partially disposed within a channel defined in the ultrasonic probe. The actuator is configured to move the needle assembly in a distal direction relative to the ultrasonic probe and through the channel of the ultrasonic probe from a retracted position to a deployed position.

The present invention comprises the provision and use of new and improved arthroscopic instrumentation for (i) harvesting a tissue biopsy from a non-critical section of a joint, and (ii) sizing and seating an autologous graft at an implant site.

An apparatus comprising: a sheath comprising a plurality of openings at a distal end; an elongate first needle extendible perpendicularly from said sheath through one of said plurality of openings; and an assembly comprising at least two second needles arranged in a predetermined pattern relative to said first needle, and extendible perpendicularly from said sheath, wherein, when extended from said distal end of said sheath: (i) each of said second needles extends a different length from said distal end of said sheath, (ii) at least a distal portion of each of said second needles is resiliently biased to extend laterally outwardly in relation to said first needle, and (iii) a lateral spread region defined by said distal portions of all of said second needles is determined based, at least in part, on a distance of said extending from said distal end of said sheath.

A biopsy device is proposed comprising a shaft and a tubular member. The shaft is movably, i.e. rotatably as well as shiftably accommodated within the tubular member and comprises a spiral at a distal end portion of the shaft, wherein the spiral is formed by a twisted sheet. Such a spiral may be considered as a laterally open thread having no solid core.

A method for removing tissues may comprise disposing a tissue resection device at a target tissue site, causing the tissue resection device to resect a core of tissue from the target tissue site, removing the core of tissue from the body, wherein the removing the core of tissue from the body creates a core cavity at the target tissue site.

A dilation assembly comprises an expandable and contractible main body having a corrugated outer surface, a guide cannula configured to be disposed through the main body to guide a movement of the main body, and an anchor configured to fix the main body in a target position.
