Abstract:
A lung volume reduction system includes a percutaneously, laparoscopically or thorocospically insertable delivery element comprising a control end which remains outside the body and an insertion end which, when in an operative position, is adjacent to an external surface of a target portion of a lung and a constriction element deployable from the distal end of the delivery element to apply compressive force to an external surface of the target portion of the lung to constrict at least one airway therein and collapse the target portion of the lung.
Abstract:
Aspects of articulating devices and methods are disclosed. An exemplary articulating device may comprise an interior core with a reinforcing extending along a central axis, an exterior layer bonded to the interior core by an interface, and a lumen extending through the exterior layer, exterior of the reinforcing element, and parallel to the central axis. A steering wire may be moveable in the lumen to articulate a distal end of the device relative to the central axis in response to a force applied to the steering wire. Related methods of manufacturing an articulating device are also described.
Abstract:
Release mechanism for medical device includes a bushing having a proximal end, a distal end and a channel extending therethrough. Plurality of extend proximally from the distal end are biased toward a release configuration in which engagement surfaces at distal ends thereof retract radially into the channel. A core pin insertable through the channel applies a radially expansive pressure to move the arms radially outward to a locking configuration. Engagement surfaces of the first and second arms connect to a retaining surface of a tissue treatment device containing capsule, which extends at an angle relative to the engagement surfaces selected so that a first portion of a force transmitted along an axis of the bushing moves the arms radially inward toward the release configuration before a second portion of the force exceeds a threshold level associated with the removal of a tissue treatment device from gripped tissue.
Abstract:
Implantable medical devices and methods for making and using the same are disclosed. An example implantable medical device may include a stent having a first configuration and a second expanded configuration. The stent may define a plurality of nodes. The stent may have a cover member disposed adjacent the nodes. The cover member may be configured to cover at least some of the nodes when the stent is in the expanded configuration.
Abstract:
This invention is directed to a medical device having an elongate shaft having a distal end and a controller coupled to the shaft. A control member can extend through at least part of the elongate shaft and at least part of the controller, wherein the control member in a tensioned configuration can be moveable by the controller to control the distal end of the shaft and the control member can be slack in an untensioned configuration. A tensioning mechanism can be configured to move relative to at least one of the elongate shaft and the controller to tension the control member and automatically lock the control member in the tensioned configuration.
Abstract:
The present invention includes a braided stent and method of making the same. The braided stent has an integral retrieval and/or repositioning member. The stent includes a first open end, a second open end and a tubular body therebetween. The retrieval and/or repositioning member extends from and is interbraided into the braided tubular body. The retrieval and/or repositioning member includes an elongated portion extending from the first open end and a second section interlooping circumferentially about the first open end such that force exerted on the elongated portion causes radially contraction of the stent end and stent body.

Abstract:
Embodiments of the disclosure include devices and systems for using an end effector. In an embodiment, a medical device may include an articulation section. The articulation section may be operatively associated with an elongate articulation member configured to move the articulation section, wherein the articulation section can be configured to receive part of a conductive member. The medical device may also include an end effector. The end effector may include an electrode and a non-conductive section encasing a junction between the electrode and the conductive member, wherein the non-conductive section can be moveably coupled to the articulation section and can be fixedly coupled to the elongate articulation member.
