A notched tissue-collection needle configured similarly to a fine-needle-aspiration needle is provided with a cutting edge disposed in the notch and configured to excise tissue into the notch for collection. A stylet may be provided through a lumen of the needle during introduction into a patient body. The needle may be provided with echogenicity-enhancing features.

A biopsy device has a flexible sheath having a terminus with a distal chamber. The distal chamber is configured with a forward facing cutting edge. The forwarding facing cutting edge has multiple movable blades, in which the movable blades are two counter rotating blades configured perpendicular or angular to a long axis of the distal chamber. Each counter rotating blade is configured to pivot from a separate axis. The biopsy has a manipulation end controllable by the user to plunge the forward facing cutting edge at a set depth or a depth selected by the user, and to engage a cutting action by the multiple movable blades at the set depth or the selected depth. The movement of the forwarding facing cutting edge enables the biopsy device to acquire a plurality of specimens for storage in the distal chamber.

Various systems and methods are provided for surgical and interventional planning, support, post-operative follow-up, and functional recovery tracking. In general, a patient can be tracked throughout medical treatment including through initial onset of symptoms, diagnosis, non-surgical treatment, surgical treatment, and recovery from the surgical treatment. In one embodiment, a patient and one or more medical professionals involved with treating the patient can electronically access a comprehensive treatment planning, support, and review system. The system can provide recommendations regarding diagnosis, non-surgical treatment, surgical treatment, and recovery from the surgical treatment based on data gathered from the patient and the medical professional(s). The system can manage the tracking of multiple patients, thereby allowing for data comparison between similar aspects of medical treatments and for learning over time through continual data gathering, analysis, and assimilation to decision-making algorithms.

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 includes a countersink having a predetermined length from the distal cutting edge of the outer needle.

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.

A biopsy device comprises a sheath equipped with a removable stylet. The sheath including a terminus with a distal chamber configured with a forward facing cutting edge comprising a plurality of movable blades. The plurality of movable blades including two counter rotating blades configured perpendicular or beveled relative to a long axis of the distal chamber, each counter rotating blade configured to pivot from a separate axis. The biopsy device further comprises a manipulation end controllable by a user to plunge the forward facing cutting edge at a sampling locus after removal of the removable stylet at a depth and to engage a cutting action by the plurality of movable blades at the depth selected to acquire at least one specimen storable in the distal chamber.
