Guidewires With Improved Fatigue Life And Methods Of Making The Same
Hancun Chen - Maple Grove MN, US Peter Skujins - Minneapolis MN, US
Assignee:
Boston Scientific Scimed, Inc. - Maple Grove MN
International Classification:
A61B 5/00
US Classification:
600585, 604525
Abstract:
A medical device, such as a medical guidewire, having a portion including an inner zone of material and an outer peripheral zone of material surrounding the inner zone of material. The inner zone of material has a first coefficient of thermal expansion and the outer peripheral zone of material has a second coefficient of thermal expansion less than the first coefficient of thermal expansion, wherein at an operating temperature the outer peripheral zone of material opposes expansion of the inner zone of material such that the outer peripheral zone of material exerts a compressive stress on the inner zone of material.
Guidewires Including A Porous Nickel-Titanium Alloy

Assignee:
Boston Scientific Scimed, Inc. - Maple Grove MN
International Classification:
A61B 5/00 A61M 25/00 C22C 28/00 C22C 19/05
US Classification:
600585, 420417, 420446
Abstract:
Medical devices and methods for making and using the same are disclosed. An example medical device may include a guidewire. The guidewire may include an elongate shaft. The shaft may include a porous metal alloy. The porous metal alloy may be arranged so that the porous metal alloy has a first pore distribution along a first portion of the shaft and a second pore distribution different from the first pore distribution along a second portion of the shaft.
Crossing Guide Wire With Corrugated Shaping Ribbon
A medical device with a corrugated shaping ribbon is provided. The corrugated shaping ribbon for the medical device, which may be provided in the form of a guide wire or catheter, specifically a crossing guide wire or catheter, provides a mechanism by which energy can be stored as the distal tip of the medical device engages a lesion or other area of occlusion within a blood vessel. By storing such energy and continuing to apply force, eventually the distal tip extends thereby releasing the stored energy and allowing the distal tip to advance or cross through the lesion.
Electrical Contact For Occlusive Device Delivery System
Hancun Chen - Fremont CA, US Lantao Guo - San Ramon CA, US Jimmy Dao - San Jose CA, US Justin Vo - San Jose CA, US Michael Williams - Dover NH, US Richard Murphy - Sunnyvale CA, US
A delivery wire assembly for delivery of an occlusive device to a location in a patient's vasculature includes a delivery wire conduit having a proximal tubular portion coupled to a distal coil portion, the respective tubular and coil portions defining a conduit lumen. A core wire is disposed in the conduit lumen and having a distal end coupled to an occlusive device, wherein an elongate electrical contact body at least partially seated in the conduit lumen and coupled to a proximal end of the core wire, the electrical contact body and the proximal tubular portion forming a junction. A coil collar is disposed around the electrical contact body near the junction.

Assignee:
Boston Scientific Scimed, Inc. - Maple Grove MN
International Classification:
A61M 25/09
US Classification:
600585, 600434, 600435
Abstract:
Medical devices and methods for manufacturing and using medical devices. An example medical device includes a core member, a tubular member coupled to the core member, and a tip member coupled to the tubular member. The tubular member may have a plurality of slots formed therein. The tip member may include a polymeric material. An intermediate member may be disposed between the tubular member and the core member that aids the bonding of the tip member thereto.
Medical Device Including A Braid For Crossing An Occlusion In A Vessel
HANCUN CHEN - MAPLE GROVE MN, US PU ZHOU - MAPLE GROVE MN, US
Assignee:
BOSTON SCIENTIFIC SCIMED, INC. - MAPLE GROVE MN
International Classification:
A61M 25/09 B32B 37/00
US Classification:
600585, 156 86
Abstract:
The invention provides design, material, manufacturing method, and use alternatives for medical devices. An example medical guidewire includes an elongate core member including a proximal region and a distal region, a braid member disposed about at least a portion of the distal region of the elongate core member, a polymer member disposed between at least a portion of the elongate core member and the braid member, and a polymer sleeve member disposed about at least a portion of the braid member. The proximal region of the core member is free of the braid member.
