Filed:

Oct 29, 2009

Appl. No.:

12/608935

Inventors:

Warren C. Sapida - Santa Clara CA, US
Bryan J. Auyoung - Santa Clara CA, US
Hester Chan - Sunnyvale CA, US
Todd W. Jenkins - San Jose CA, US

Assignee:

Kyphon Sarl - Neuchatel

International Classification:

A61M 29/00

US Classification:

604 9601, 60410301

Abstract:

An inflatable bone tamp for performing a minimally invasive surgical procedure includes an inflatable structure that exhibits an outwardly tapering expansion profile. The outward taper can beneficially allow the inflatable bone tamp to exert greater targeted force in difficult environments. For example, in a vertebra with a compression fracture, the outwardly tapering expansion profile of the inflatable bone tamp can result in greater lifting force being applied to the endplates of the vertebra, thereby increasing the likelihood of restoring the height lost due to the compression fracture.

International Classification:

A61F 2/06

US Classification:

623 123

Abstract:

An apparatus includes an expandable member and an elongate assembly. The expandable member is configured to displace a first portion of a bone structure relative to a second portion of the bone structure when moved from a collapsed configuration to an expanded configuration. The elongate assembly includes a shaft and an elongated member disposed with a lumen defined by the shaft. A proximal end portion of the expandable member is coupled to a distal end portion of the shaft such that the proximal end portion of the expandable member does not rotate relative to the distal end portion of the shaft when at least a portion of the expandable member is twisted about the elongated member through at least four revolutions.

International Classification:

A61M 29/00

US Classification:

604096010

Abstract:

Systems and methods for providing a cavity in an interior body region are described. In one described method, a frame comprising a plurality of frame members disposed adjacent an expansible body is inserted into a treatment area along a path established by a hollow member. The expansible body is expanded in the treatment area, and the expansible body is constrained from expanding by the frame.

International Classification:

A61M 29/00

US Classification:

604 9601

Abstract:

An inflatable bone tamp for performing a minimally invasive surgical procedure includes an inflatable structure having at least three contiguous lobes, that when inflated, cause the inflatable structure to exhibits an outwardly tapering expansion profile. By forming the inflatable structure such that the reduced-diameter junction(s) between the lobes has a greater wall thickness then the adjacent lobes, the durability and abrasion-resistance of the inflatable bone tamp can be increased.

International Classification:

A61B 17/56
A61M 25/10

US Classification:

606 86 R, 604 9601

Abstract:

A balloon catheter can include an actively steerable element for adjusting the configuration of the balloon after placement at a target location. By coupling the actively steerable element to the balloon, any articulation of the actively steerable element will also re-configure the position of the balloon, thereby enabling greater control over procedures that make use of such a balloon catheter. The active steering capability can also enhance the material manipulation capabilities of the balloon catheter, and enable operations and actions that are not possible with a non-steerable balloon catheter.

Assignee:

KYPHON SARL - Neuchatel

International Classification:

A61B 17/56

US Classification:

606 86 R

Abstract:

An inflatable bone tamp for performing a minimally invasive surgical procedure includes an extension controller for adjusting the relative position between the inner shaft and the outer shaft, thereby allowing the working length of the inflatable structure (e.g., balloon) to be adjusted and set prior to (and/or optionally during) use. The extension controller allows for customization of the inflatable bone tamp performance characteristics to enhance surgical effectiveness for a given physical condition.

International Classification:

A61B 17/56

US Classification:

606105

Abstract:

A device and method for treating bone fractures/lesions using an inflatable body is provided. The inflatable body includes a balloon having a substantially flat horizontal surface for quick easy insertion into bone beneath the fracture so as to align misaligned fragments of the fracture and/or to collapsed bone. The body has a shape and size to compress at least a portion of the cancellous bone to form a cavity in the cancellous bone and/or to restore the original position of the outer cortical bone, if fractured or collapsed. The inflatable body has a stylet attached to it's distal end so that once the inflatable body is deflated it can be twisted about the stylet to have a smaller profile so as to be easily withdrawn from the bone.

Assignee:

MEDTRONIC HOLDING COMPANY SÀRL - Tolochenaz

International Classification:

A61B 17/88

Abstract:

A medical balloon device includes an outer member extending along an axis. An inflatable member has a proximal end extending from a first end of the outer member and a distal end. An inner member is positioned within the outer member and the inflatable member such that a first end of the inner member is coupled to the distal end of the inflatable member. A support member is movably disposed within the inner member and includes a first end configured to removably engage the first end of the inner member. Translation of the support member along the axis causes the inflatable member to move between a first position in which the inflatable member has a first length and a first profile and a second position in which the inflatable member has a second reduced length and a second reduced profile. Methods of use are disclosed.
