A biopsy device includes coaxially disposed inner and outer needles in which the outer needle tip is configured for obtaining a tissue sample. The inner surface of the outer needle includes a tissue retention feature which may include a countersink and/or a feature formed in the inner surface. The device may be introduced to a biopsy site through an introducer in which the introducer is vented and/or a certain ratio of introducer inner diameter and biopsy device outer diameter is maintained.

Full core biopsy device

A flexible biopsy needle assembly includes a flexible coring stylet that is slidably disposed within a flexible outer cannula. The stylet includes an elongated body, a tip, a sampling notch adjacent to the tip, and at least one ferrule along the length of the body. The cannula includes an elongated tubular body defining a lumen sized for sliding passage of the stylet, a cutting edge at the opening of the lumen, and an array of slits along the length of its body. The slits are sized to allow the diameter of the ferrule(s) to extend partially therein. The slits and ferrule(s) interact to limit or control the flexibility of the cannula at the location of the slits.

A biopsy device includes coaxially disposed inner and outer needles in which the outer needle tip is configured for obtaining a tissue sample. The inner surface of the outer needle includes a tissue retention feature which may include a countersink and/or a feature formed in the inner surface. The device may be introduced to a biopsy site through an introducer in which the introducer is vented and/or a certain ratio of introducer inner diameter and biopsy device outer diameter is maintained. The full core devices also permit a tighter tolerance between the I.D. and O.D. of the outer cannula and stylet, respectively, which further permits the use of a smaller gage introducer. Full devices also include a sample trap assembly operable to enlarge the sample cavity after the full core sample has been obtained.

The inner surface of the outer needle includes a tissue retention feature which may include a countersink and/or a feature formed in the inner surface. The device may be configured such that the inner needle does not extend past a certain point within the outer needle.

A surgical cutting instrument for cutting tissue includes an outer cannula with a cutting opening and a cutting member within the cannula. The cutting member is connected to a source of reciprocation, and as the cutting member reciprocates the cutting member head is guided by a sloped member within the cannula to essentially a zero clearance position relative to a cutting edge of the cutting opening of the cannula. The instrument cleanly severs tissue extending through the cutting opening into the outer cannula.

An introducer guidefor introducing medical items into an internal tissue of a patient is provided. The guideincludes a cannuladefining a lumen sized to receive the item and a lateral openingA ramp is disposed within the lumen adjacent and inclined toward the lateral openingA hub' is attached to the second endof the cannulaThe hub&#x2032; includes a gripping portion&#x2032; configured to be held when inserting and positioning the introducerThe gripping portion&#x2032; has a length lsufficient for gripping and a tactile indicatordisposed along substantially the entire length lof the gripping portionon the hub&#x2032;. The indicatorhas a fixed angular relationship with the lateral openingThe invention also includes methods for obtaining a biopsy sample and methods for treating lesions.

Surgical and pharmaceutical site access guide

A biopsy needle assembly for use in a biopsy gun includes coaxially slidably engaged outer needle and inner needles. The inner needle defines a cavity adjacent its distal end for receiving a tissue sample. A first hub is attached to the proximal end of the inner needle, and a second hub is attached to the proximal end of the outer needle. An elongated pin having a first end and a second end is fixedly attached to the first hub at the first end of the pin. The second end is in sliding contact with the second hub so that the second hub and the pin are slidable relative to each other. A stop engagement is provided between the second end of the pin and the second hub and is configured to prevent disengagement of the outer and inner needles and to maintain a specific physical relationship between the hubs.

A biopsy instrument for use in a biopsy gun includes a hollow outer needle defining a lumen therethrough and an inner needle slidably engaged within the lumen. The inner needle defines a cavity adjacent its distal end for receiving a tissue sample. A first hub is attached to the proximal end of the inner needle, and a second hub is attached to the proximal end of the outer needle. An elongated pin having a first end and a second end is fixedly attached to the first hub at the first end of the pin. The second end is in sliding contact with the second hub so that the second hub and the pin are slideable relative to each other. A stop engagement is provided between the second end of the pin and the second hub and is configured to prevent disengagement of the outer and inner needles and to maintain a specific physical relationship between the hubs.

A surgical cutting instrument includes a hollow hub that has a working portion which terminates at a working end and a connection portion which terminates at a connection end. The connection portion defines a cavity and a lock member which projects from an outer surface of the connection portion A surgical cutting element extends from the working end and is operationally connected to a source of motion. A hollow hub connector has a cylindrical wall with a hand-piece connection portion and a hub engagement portion The hub engagement portion defines a chamber for receiving the connection portion of the hub The chamber has a longitudinal axis A parallel to the length of the hub connector The hub engagement portion further defines a channel through the cylindrical wall for receiving the lock member The channel is in communication with the chamber and has a longitudinal section defined along the length L of the connector. The channel also has a second transverse section communicating with the longitudinal section at a first end and having a second opposite end Further, the channel has a locking recess defined in the wall perpendicularly to the transverse section and in communication with the opposite end of the transverse section The locking recess is sized to receive the lock member A spring element urges the lock member into the locking recess when the locking member is rotated into the opposite end of the transverse section of the channel

Bone marrow biopsy devices, assemblies and methods are provided for extracting bone marrow tissue samples. The assemblies include an outer cannula or biopsy needle and a biopsy extractor sized for insertion into the proximal end of the outer cannula. The biopsy needle includes a tapered portion at the distal end. The extractor includes a cannula and a distal working end. The distal working end has a diameter larger than the diameter of the tapered portion of the biopsy needle lumen. The working end includes a body portion adjacent the cannula and a cutting head having a cutting tip. A hinge is engaged between the body portion and the cutting tip. The hinge allows the cutting head to bend when pushed into the tapered distal end of the outer cannula allowing the cutting tip to sever the tissue sample.
