    摘要： An automatic control system for a vacuum-assisted automatic core biopsy device (10) is provided, wherein the automatic core biopsy device (10) comprises a housing (12), out of which extends a needle assembly (14) including a hollow outer piercing needle (16), an inner cutter (18) having a lumen (20), a probe housing (22), and a tissue receiving notch (24). The automatic control system (92) is computerized to move the hollow outer piercing needle (16) automatically to the target tissue lesion, as was true in the prior art, but also is programmed to automatically control the rotational orientation of the piercing needle (16), and its associated tissue receiving notch (24), as well as the axial positioning and rotation of the cutting cannula (18). Consequently, a clinician user need only mark the desired locations within the target location from which tissue samples are desired and the automatic control system will operate the device to retrieve samples from the marked locations.

    摘要： An innovative bone anchor and methods for securing connective tissue, such as tendons, to bone are disclosed which permit a suture attachment which lies entirely beneath the cortical bone surface, and wherein the suturing material between the connective tissue and the bone anchor is oriented in a direction generally transverse to the longitudinal axis of the bone anchor, so that axial pull-out forces exerted on the bone anchor are minimized. The suture attachment to the bone anchor involves the looping of a substantial length of suturing material around a shaft of the anchor, thereby avoiding an eyelet connection which requires a knot and which concentrates stress on a very small portion of the suturing material. Thus, failure rates are greatly decreased over conventional techniques, and the inventive procedures are significantly easier to perform than conventional techniques.

    摘要： An implantable marking device is provided which is designed to percutaneously deliver permanent markers to desired tissue locations within a patient's body, even if the desired locations are laterally disposed relative to the distal end of the delivery device, as is the case for conduit or cavity walls. This provides several advantages to the physician in diagnosis and management of tissue abnormalities, such as a means of localization of a tissue abnormality for follow-up surgical treatment, and a means of tissue abnormality site identification for purposes of ongoing diagnostic follow-up. In one preferred construction, a radiographic clip is configured in the form of a surgical staple. A disposable tissue marker applier, which comprises a flexible tube, pull wire, and squeeze handle, is employed to advance and deploy the clip to a desired tissue location. Either a flexible or a rigid introducer is also provided for providing access to the site to be marked.

    摘要： Implantable devices and methods of use are disclosed for marking the location of a biopsy or surgery for the purpose of identification. The methods include providing a biodegradable radiodense implant and taking a tissue sample from a biopsy site within a breast of a patient. The biodegradable implant is then positioned at the biopsy site. The tissue sample is tested and the biopsy site is then relocated. In one embodiment, the entire implant is radiodense. In another embodiment, the entire implant is biodegradable. Methods of using a biodegradable implant having a radiodense material and a biodegradable implant that is visible using an imaging system are also included.
