Expandable Guide Sheath And Apparatus And Methods Using Such Sheaths
US Patent:
7762995, Jul 27, 2010
Filed:
Apr 24, 2003
Appl. No.:
10/423321
Inventors:
Christian Scott Eversull - Palo Alto CA, US

Assignee:
The Board of Trustees of the Leland Stanford Junior University - Palo Alto CA
International Classification:
A61M 5/00
US Classification:
604264
Abstract:
Apparatus and methods are provided for accessing body lumens and/or for delivering instruments into body lumens, e. g. , vessels within a patient's vasculature. A flexible sheath is provided that is expandable from a contracted condition to an enlarged condition wherein the sheath at least partially defines a lumen therein. The sheath is lubricious and has a relatively thin wall, thereby providing a collapsible/expandable guide for delivering fluids and/or instruments through tortuous anatomy and/or into relatively narrow passages. The sheath is advanced from an entry site to a body lumen in the contracted condition. Once the sheath reaches a target body lumen, the sheath is expanded to the enlarged condition, thereby defining a lumen within the sheath, and fluids and/or instruments are introduced into the body lumen via the sheath lumen. Upon completing the procedure, the sheath is removed from the body lumen.

International Classification:
A61B 1/00, A61B 1/05, A61B 1/005, A61B 1/018
US Classification:
600104, 600116, 600109
Abstract:
Apparatus and methods for locating features within a body cavity using a catheter including proximal and distal ends, a transparent balloon carried on the distal end, and an optical imaging assembly carried on the distal end for imaging through the balloon. The balloon includes a channel extending therethrough to a lumen extending through the catheter. A guidewire or other localization member is received in the lumen that is extendable through the channel. During use, the catheter is inserted into a right atrium of a heart, and the balloon is expanded and placed against the wall of the heart to locate the coronary sinus. Sufficient force is applied to clear blood between the surface and the wall and clear the field of view of the imaging assembly. The catheter is manipulated to locate the coronary sinus, whereupon the localization member is advanced into the coronary sinus.
Devices And Methods For Injection Of Multiple-Component Therapies
US Patent:
8057426, Nov 15, 2011

Mario Maciel - Pinon Hills CA, US
Assignee:
Medtronic Vascular, Inc. - Santa Rosa CA
International Classification:
A61M 37/00
US Classification:
604 82
Abstract:
Devices and methods for injecting or otherwise delivering multiple-component therapies to human or animal subjects. Devices having injectors (e. g. , syringes) attached to biaxial or coaxial injection cannula(s) are used to deliver multiple components of a particular therapy such that those components become combined shortly before or upon exiting the injection cannula(s). In some embodiments, the injector devices of the present invention may include a first set of finger grips at a first location and a second set of finger grips at a second location. Also, in some embodiments, the injector devices of the present invention may include depth slops for controlling the depth within tissue at which the therapeutic substance is delivered. Also, in some embodiments, the injector devices of the present invention may include refill manifolds with attached syringes or other reservoirs containing the component substances to facilitate refilling of the injectors.

International Classification:
A61M 31/00, A61M 37/00
US Classification:
604093010, 604509000
Abstract:
Methods and systems are disclosed for treating injury to cardiac tissue by delivering a composition which provides structural support to the cardiac tissue. The composition helps to prevent chamber remodeling by providing structural reinforcement of the tissue or structural reinforcement of the tissue combined with biological therapy. The structurally reinforcing composition can thicken the wall of a heart, or act to prevent further thinning and thereby provide resistance against further remodeling. A number of compositions are disclosed, including multi-component substances such as autologous platelet gel, and other substances. The compositions disclosed can contain additives to augment/enhance the desired effects of the injection.
