Benefits of technology

[0005] Apparatuses and methods for performing minimally-invasive medical procedures are disclosed herein. In one embodiment, an apparatus includes a probe configured to be percutaneously deployed within an interior portion of a bone structure. At least a portion of the probe is configured to contact a portion of the interior portion of the bone structure when the probe is actuated within the interio

Problems solved by technology

The expansion path of the inflatable medical device and the expanded shape of the device can at times be unpredictable, as the device will typically expand within the space provided in a path of least resistance.
For example, for portions of a patient's body having a non-uniform hardness, an inflatable medical device may not expand in a predictable manner.

Embodiment Construction

[0025] In at least some embodiments, the medical devices described herein are configured for percutaneous deployment within an interior area of a patient's body, such as within a bone structure or soft tissue area of a patient. For example, a medical device according to an embodiment of the invention may include an expandable member configured to compact and forcibly displace bone material (e.g., cancellous bone) within a bone structure, such as a vertebra, of the patient when expanded. A medical device according to an embodiment of the invention may also include an expandable member configured to be movably disposed within a cannula.

[0026] Note that, as used in this specification and the appended claims, the singular forms “a,”“an” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, the term “a lumen” is intended to mean a single lumen or a combination of lumens. Furthermore, the words “proximal” and “distal” refer to direction clos...

Abstract

In one embodiment, an apparatus includes a probe configured to be percutaneously deployed within an interior portion of a bone structure. At least a portion of the probe is configured to contact a portion of the interior portion of the bone structure when the probe is actuated within the interior portion of the bone structure. The apparatus also includes a pressure indicator that is configured to provide pressure data associated with a pressure externally exerted on the probe when the probe is actuated within the interior portion of the bone structure. In some embodiments, the probe includes an expandable member. In some embodiments, the probe includes an expandable low-compliance balloon.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application claims priority to U.S. Provisional Application No. 60 / 683,803 entitled “Low-Compliant Expandable Medical Device,” filed May 24, 2005, the disclosure of which is incorporated herein by reference in its entirety.BACKGROUND [0002] The invention relates generally to medical devices and procedures, and more particularly to a low-compliance expandable medical device for use in medical procedures. For example, the medical device may be inserted inside a bone structure to create a cavity. [0003] Inflatable devices are used in a variety of medical procedures. Many inflatable medical devices are constructed with elastic or highly-compliant materials that allow the inflatable medical devices to expand within the particular space in which they are deployed. The expansion path of the inflatable medical device and the expanded shape of the device can at times be unpredictable, as the device will typically expand within the space prov...
