Appl. No.:

12/824139

Inventors:

Eduardo Chi Sing - Dana Point CA, US
Mark A. Cole - Santa Ana CA, US
Tommy G. Nguyen - Invine CA, US

Assignee:

Cianna Medical, Inc. - Aliso Viejo CA

International Classification:

A61B 5/05
A61B 5/07
A61B 10/02

US Classification:

600302, 600424, 600562

Abstract:

Apparatus, systems, and methods are provided for localizing lesions within a patient's body, e.g., within a breast. The system may include one or more markers implantable within or around the target tissue region, and a probe for transmitting and receiving electromagnetic signals to detect the one or more markers. During use, the marker(s) are into a target tissue region, and the probe is placed against the patient's skin to detect and localize the marker(s). A tissue specimen, including the lesion and the marker(s), is then removed from the target tissue region based at least in part on the localization information from the probe.

International Classification:

A61B 1739

US Classification:

606 45

Abstract:

This invention provides an inventive tissue sampling probe which offers many advantages over probes available in the prior art. Unexpectedly superior results are obtained in connection with the retrieval of intact tissue specimens, because of a unique combination of cutting features, including, for example, the employment of an electrosurgical cutting element and a vacuum assist in one preferred embodiment. A particularly important feature of the invention is the ability to manipulate the electrosurgical cutting element to cleanly sever the distal end of the tissue specimen. In certain embodiments, this is accomplished without any cutting impact on surrounding tissue. The versatility of the invention permits its use in many applications, including, for example, breast biopsies, laparoscopic surgery, and lymphadenectomy procedures.

International Classification:

A61B17/10

US Classification:

606142

Abstract:

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.

International Classification:

A61F 2/16
A61F 9/007

Abstract:

A system for delivering an intraocular lens (IOL) is disclosed, including: a handpiece including a barrel defining an elongate passage, a pushrod disposed inside the elongate passage, and a plunger coupled to the pushrod; and a delivery unit coupled to a first end of the barrel, the delivery unit including a delivery tube and a lens holder coupled to the delivery tube, the lens holder including a lead haptic shelf arranged to receive a lead haptic of an IOL that is contained inside the lens holder, wherein the lead haptic shelf is configured to fold the lead haptic of the IOL over a body of the IOL while permitting the IOL to travel under the lead haptic shelf when the IOL is displaced from the lens holder to the delivery tube by the pushrod during delivery of the IOL into a patient's eye.

International Classification:

A61N 5/10

Abstract:

Apparatus for delivering brachytherapy to a target tissue region includes an elongate body including a proximal end, a distal end sized for introduction into a tissue tract and carrying a plurality of elongate members including pathways for receiving a source of radiation. The elongate members are movable between collapsed and expanded configurations. During use, a tract is created through tissue, and the elongate body carrying the elongate members is advanced through the tract into a target location with the elongate members in the collapsed configuration. The elongate members are directed to the expanded configuration at the target location, and radiation is delivered to treat tissue at the target location, e.g., by introducing one or more radiation sources along the pathways.

International Classification:

A61F 2/16

Abstract:

Accordingly, embodiments of the present invention provide an IOL insertion device that facilitates the injection of the IOL in a controlled manner The insertion device includes a front modular portion and an injector. The modular portion may be preloaded with an IOL and coupled with the injector. The injector includes a distal portion, a body, and a plunger. The distal portion includes a front seal which has a longitudinal bore at the center, through which a distal portion of the plunger passes. The plunger tip is tapered. The plunger also includes a sealing element situated between its distal portion and its proximal portion. The sealing element includes a small aperture through which a fluid, such as a viscoelastic or a balanced salt solution (“BSS”) and the like, may pass toward the proximal end of the body when the plunger advances distally. As the fluid passes through the small aperture on the sealing element on the plunger, a constant speed and force is maintained as the IOL is ejected into the eye.

International Classification:

A61F 2/16

Abstract:

A rear-loaded injector cartridge for an intraocular lens (IOL) having a proximal opening that provides a haptic slot. The haptic slot receives a leading haptic of an IOL loaded therein, and temporarily retains the leading haptic while the optic of the IOL is inserted into a holding area of the cartridge. As the optic passes by, the leading haptic folds over the top of the optic, on its anterior side. The length of the haptic retention slot is sufficient to maintain the leading haptic in its anteriorly folded position while the IOL remains in holding area, typically while the cartridge is mated with a handpiece of the injector. The cartridge also has a rear or proximal cut out which advantageously keys with a similarly-sized rail on the handpiece so that the cartridge cannot be inserted in the wrong way.
