摘要： Miller-Bates-Hall-Osborne 1-2-2-2 A medical device for localizing a nonpalpable breast lesion. The device includes a tubular introducer needle and a wire guide positioned therein for inserting into a breast to the site of the lesion. The wire guide includes a distal portion which is preformed into a resilient helical coil configuration for locking into position about the lesion. The distal portion includes a superelastic metallic alloy for maintaining the helical coil configuration after repeated extensions from and retractions into the needle passageway. With a visualization aid such as an X-ray film or ultrasound, a radiologist typically inserts the needle with the wire guide positioned therein into the breast to the site of the lesion and extends the distal portion of the wire guide from the needle. The distal end of the needle includes a plurality of indentations for enhancing the ultrasound visualization thereof. As the distal portion of the wire guide emerges from the needle, the acuate distal end of the wire guide cuts into and scribes a helical path about the tissue distal to the lesion. The remainder of the distal portion of the wire guide follows the path scribed by the acuate distal tip and locks about the tissue distal to the lesion. Should the needle and wire guide not be appropriately positioned, the distal portion of the wire guide is retracted into the passageway of the needle to reposition the needle and guide. After desired positioning, the needle is removed with the wire guide remaining in a locked position distally about the lesion for guiding guides the surgeon to the lesion site during subsequent surgery.

摘要： 57 A catheter wire guide having an axially movable mandril with a tapered tip for permitting the flexibility of the distal tip of the wire guide to be varied. The mandril is coated with a lubricating material, such as Teflon, for facilitating the smooth movement of the mandril within the wire guide.

摘要： A balloon catheter (10) having an expandable and collapsible elastic balloon (12) is shown, wherein the balloon (12) is reinforced by knitted fabric (23) such that the balloon (12) can not expand beyond a predetermined diameter regardless of the internal pressure applied to the balloon (12). The knitted construction (23) permits the balloon (12) to expand in diameter without shortening in length, and permits the balloon (12) to collapse smoothly without folds and wrinkles.

摘要： A removable vena cava filter configured for simplified delivery to and retrieval from the vena cava of a patient is disclosed. In one embodiment, the filter comprises a plurality of primary struts having first ends attached together along a longitudinal axis. The primary struts are movable between a closed state during delivery to the blood vessel and an open state when engaged with the blood vessel. Each primary strut comprises a first portion, a second portion, and an axial bend. The first portion extends from the first end and generally is disposed within a first portion plane intersecting the longitudinal axis. The axial bend is oriented along a circumferential direction relative to the longitudinal axis. The second portion generally is disposed within a second portion plane intersecting the first portion plane and terminates at an anchoring hook.

摘要： The present invention involves a removable filter for capturing thrombi in a blood vessel. The filter comprises a plurality of struts having first ends attached together along a longitudinal axis (X) of the filter. Each strut has a body member extending from the first end along the longitudinal axis to an anchoring hook defining a strut axis (S). Each strut is configured to move along a strut path (P) relative to the longitudinal axis between an expanded state for engaging with the blood vessel and a collapsed state for filter delivery or retrieval. Each anchoring hook has an angle of up to about 90 degrees relative to the strut axis.

摘要： A removable vena cava filter configured for simplified delivery to and retrieval from the vena cava of a patient is disclosed. The filter includes struts configured to be arranged in consistent orientation together between expanded (opened) and collapsed (closed) configurations, thereby minimizing entanglement of the struts. Each of the struts has a circumferential bend relative to the longitudinal axis of the filter. The circumferential bends allow for consistent orientation of the struts when moved between the expanded and collapsed configurations and when placed in the closed configuration of the filter.

摘要： The present invention involves a removable filter for capturing thrombi in a blood vessel. The filter comprises a plurality of primary struts and a plurality of secondary struts. The plurality of primary struts has first ends attached together along a longitudinal axis. Each primary strut has an arcuate segment extending from the first end to an anchoring hook. The primary struts are configured to move between an expanded state for engaging the anchoring hooks with the blood vessel and a collapsed state for filter retrieval or delivery. Each primary strut is configured to cross another primary strut along the longitudinal axis in the collapsed state such that each anchoring hook faces the longitudinal axis away from the blood vessel for filter retrieval or delivery. The plurality of secondary struts has connected ends attached together along the longitudinal axis. The secondary struts extend therefrom to free ends to centralize the filter in the expanded in the blood vessel.
