International Classification:

A61B 500

US Classification:

600567

Abstract:

A device for encapsulating tissue specimens includes a wand assembly, a sheath, and a guide assembly. The guide assembly pulls, draws, or otherwise moves the sheath about the tissue specimen. The wand assembly is disposed proximate to the tissue specimen, typically either adjacent or through the specimen. In an aspect of the encapsulating device, the guide assembly has sheath deployment members that are disposed about the tissue specimen. The sheath, which is attached to ends of the sheath deployment members and the wand assembly, is drawn over the tissue specimen as the sheath deployment members are pushed or pulled. In another aspect of the device, the guide assembly is an arm or a housing that rotates about the tissue specimen. The sheath, which is secured at one end to the guide assembly and at another end to the wand assembly, is drawn over the tissue specimen as the guide assembly rotates. The sheath may be made up of porous material, non-porous material, selectively permeable material, woven material, braided material, knit material, web material, mesh material, a film material, a flexible laminate material, or of an elastic material.

US Classification:

606144, 606139, 606147

Abstract:

A method and device for the placement of sutures and for the purpose of approximating tissue. The invention relates to devices for approximation, ligation and fixation of tissue using a suture, to various constituent parts comprising said devices, and particularly to the placement of sutures into certain difficult to access ligamental structures, to the approximation of tissue separated by means of an endosurgical trocar being inserted into a body cavity, and to approximation, ligation, and fixation of body tissue using both traditional open surgical and endosurgical techniques and instruments. The invention provides for the loading of suture material including needles into the device, introduction and placement of the device into the body cavity, with the distal end having deployable needle guides, extending the needle guides either simultaneously or individually to the periphery of the wound, engaging the wound with the needle guides, driving the needles and suture material through the tissue to be approximated into a catch mechanism, retracting the needle guides and withdrawing the device, leaving a loop of suture material in the margin of tissue. The suture may then be tied to approximate the wound and excess suture material cut off. The invention also provides for the placement of sutures for the endoscopic approximation, fixation, and ligation of tissues within a body cavity including the driving and retrieval of needle and suture combinations, and facilitating the tying of knots.

International Classification:

A61B 1818

US Classification:

606 45, 606 41, 600562

Abstract:

A system for accessing a desired site within a patients body includes a cannula defining an inner lumen that opens into a longitudinally extending side aperture formed in the side of the cannula, near its distal end. An electrosurgical stylet slidably fits inside the inner lumen. At the distal end of the stylet is an electrosurgical electrode capable of ablating tissue and permitting advancement of the system into a patients body. The electrode, in an expanded deployed configuration, can be wider than the maximum transverse dimension of the cannula, but it may be deflected toward the center of the stylet so that the electrode fits within the inner lumen of the cannula, permitting the stylet to be inserted and removed through the cannula. An elongate guide tube having a central axial bore which communicates with an orifice in the side of the guide tube can be inserted into the inner lumen of the cannula such that the guide tube orifice coincides with the longitudinally extending side aperature of the cannula. In use, the stylet with the cannula disposed about it is advanced into the patients tissue, using electrosurgical ablation, until the side aperture of the cannula is disposed adjacent a desired site within the patient.

International Classification:

A61B 1000

US Classification:

600564

Abstract:

Devices and methods are provided for securely affixing a medical instrument to desired tissue in a patients body, using a fixation agent. Such medical instruments may comprise localization wires or tissue acquisition instruments, such as biopsy instruments, for example. In the case of tissue acquisition instruments, the inventors have discovered significant advantages for securely affixing the distal end of the tissue acquisition instrument to a particular tissue target area. For example, such an approach permits the imaging environment to be uncoupled from the procedural environment so that expensive and often unavailable imaging equipment, such as stereotactic imaging equipment, need not be used. In a preferred embodiment, a bonding agent, such as adhesive, surgical glue, or a solvent, is used as the fixation agent.

International Classification:

A61B 1818

US Classification:

606 45, 606 48

Abstract:

The invention is directed to an electrosurgical device having a shapeable elongate cutting electrode having a free distal end with an exposed length of at least about 0. 25 inch and secured by its proximal end to the distal end of a handle. The electrosurgical device is designed for use with a high frequency electrosurgical generator which has an output at a frequence of between about 1 MHz and about 10 MHz, preferably about 3 to about 8 MHz. Preferably, the output has an essentially sinusoidal waveform with little harmonic distortion. The methods provide for the enhanced cutting of a variety of tissue including muscular, connective, glandular and fatty tissue. The device is particularly suitable in performing a breast biopsy.
