Filed:

Mar 11, 2010

Appl. No.:

12/722449

Inventors:

Bryan J. Auyoung - Santa Clara CA, US
Hester Chan - Sunnyvale CA, US
Warren C. Sapida - Santa Clara 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 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.

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:

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once the inflatable body is deflated it can be twisted about the stylet to have a smaller profile so as to be easily withdrawn from the bone.

Chi LONG - Santa Clara CA, US
Todd JENKINS - Santa Clara CA, US

International Classification:

A61B 17/225

Abstract:

The present invention provides a catheter for treating occlusions in blood vessels. An exemplary catheter for treating occlusions in blood vessels comprises a tubular inner member including a base segment with a first lumen defining a fluid inlet port, and a second lumen defining a fluid outlet port. An extension segment is distal to the base segment. The extension segment has a reduced cross-section. An emitter assembly includes a first insulated wire extending through the second lumen and a second insulated wire, and a conductive sheath wrapped circumferentially around the first insulated wire, the second insulated wire, and the extension segment. A cap or balloon is sealably attached to the distal end of the catheter and surrounds the emitter assembly, said cap or balloon being fillable with conductive fluid.

International Classification:

A61B 17/22

Abstract:

The present invention provides a catheter for treating occlusions in blood vessels. The catheter includes at least one electrode pair positioned inside of a flexible angioplasty balloon at the distal end of the catheter. In some designs, the electrode pairs are arranged in a low-profile or coplanar configuration, reducing the diameter of the distal end of the device and permitting treatment of tight and hard-to-cross occlusions. The flexible angioplasty balloon has an extremely low profile and does need to be folded before insertion of the catheter into the cardiovascular system. During treatment, the balloon can be expanded a relatively small amount sufficient to immerse the electrode pairs in a conductive fluid before generating shock waves across the electrodes to treat the occlusion. The balloon can be made of material having elastomeric properties such that it returns to its original low profile configuration when it is deflated following treatment.

Todd Jenkins - San Jose CA, US

International Classification:

A61M 1/10
A61M 1/12

Abstract:

A catheter pump is disclosed. The catheter pump can include an impeller and a catheter body having a lumen therethrough. The catheter pump can also include a drive shaft disposed inside the catheter body. A motor assembly can include a chamber. The motor assembly can include a rotor disposed in the at least a portion of the chamber, the rotor mechanically coupled with a proximal portion of the drive shaft such that rotation of the rotor causes the drive shaft to rotate. The motor assembly can also comprise a stator assembly disposed about the rotor. The motor assembly can also include a heat exchanger disposed about the stator assembly, the heat exchanger may be configured to direct heat radially outward away from the stator assembly, the rotor, and the chamber.

Abstract:

A catheter pump system is disclosed. The catheter pump system can include a shaft assembly and an impeller coupled with a distal portion of the shaft assembly. A motor assembly can impart rotation on the impeller through the shaft assembly, the motor assembly comprising a motor which rotates the shaft assembly. The catheter pump system can include a fluid pathway which conveys fluid proximally during operation of the catheter pump system. A seal can be disposed between the motor assembly and the impeller. The seal can be configured to impede or prevent the fluid from the fluid pathway from entering the motor assembly at least about an outer periphery of the shaft assembly. The seal can comprise an opening through which a portion of the shaft assembly extends.
