Abstract: A delivery/deployment system having a control handle configured to control delivery and/or deployment of a medical device with arms configured to grasp tissue therebetween. The system may include a device spreader with arms engaging the medical device arms and controlled by an actuator operably coupled with the control handle. The control handle may include a lever pivotable to similarly pivot the device spreader and medical device arms open or closed. A device retention assembly may be provided to retain the medical device with respect to the device spreader. The control handle may include a release element movable to shift the retention assembly into a disengaged configuration allowing release of the medical device from the device spreader. The control handle may axially translate and/or rotate the device spreader into a desired position, and may be fixable in position by a handle lock once in a desired position.

Abstract: A steering system for a steerable flexible elongate member such as for delivering a medical device and/or system. The steering system may be configured for two-way or four-way steering. A control knob is rotatable to control steering of the steerable flexible elongate member in a first direction or a second direction within a steering plane. In a four-way steering system, a first control knob steers the steerable flexible elongate member in a first steering plane, and a second control knob steers the steerable flexible elongate member in a second steering plane transverse to the first steering plane. The steering system may be supported on a stand configured to allow rotational support of the steering system. The stand may support two steering systems in a manner allowing relative axial translation therebetween.

Abstract: Delivery devices for an occlusive implant and method for making and using delivery devices are disclosed. An example delivery device may include a delivery sheath having a proximal region and a laser cut distal tip region. A reinforcing member may extend along the proximal region. The laser cut distal tip region may have one or more laser cuts formed therein that form a patterned distal section. The patterned distal section may be configured to shift between a delivery configuration and an expanded configuration. A core member may be slidably disposed within the delivery sheath. An occlusive implant may be releasably coupled to the core member.

Abstract: A medical device for cutting a suture during a minimally invasive procedure may include an elongate shaft having a proximal end, a distal end, and a central longitudinal axis, a handle disposed at the proximal end of the elongate shaft, the handle including an actuation mechanism, and a cutting blade disposed proximate the distal end of the elongate shaft. The cutting blade is axially translatable within the elongate shaft in response to operation of the actuation mechanism. The elongate shaft includes a distal port to receive a suture. The elongate shaft includes a transverse slot extending inward from an outer surface of the elongate shaft generally perpendicular to the central longitudinal axis. The elongate shaft includes a suture lumen extending from the distal port axially within the elongate shaft to the transverse slot. The cutting blade intersects the transverse slot adjacent the suture lumen.

Abstract: A steerable catheter includes a catheter shaft having a lumen defined by a catheter wall, a proximal portion, a distal portion, and a length extending therebetween, and at least one pullwire extending along the length of the catheter shaft and coupled to the catheter wall. The at least one pullwire has a proximal section extending along the proximal portion of the catheter shaft in a first radial position, a distal section extending along the distal portion of the catheter shaft in a second radial position, and a transition zone connecting the proximal section and the distal section. The second radial position is offset circumferentially from the first radial position.

Abstract: A medical device for cutting a suture during a minimally invasive procedure includes an elongate shaft, a handle housing disposed at the proximal end of the elongate shaft, and a cutting blade disposed proximate the distal end of the elongate shaft. A proximal portion of the handle housing includes an actuation mechanism including a lever arm having a first portion disposed outside of the handle housing and extending distally from the proximal portion of the handle housing. Translation of the first portion of the lever arm relative to the handle housing axially translates the cutting blade within the elongate shaft. A medical device system may include a stand configured to support at least one medical device and a medical device securable to the stand.

Abstract: A delivery and deployment system having a control handle operable to deliver and/or deploy an implantable device, e.g., transluminally. A steering control system may include a steering control knob rotatable about the longitudinal axis of the handle to axially pull on a steering element to steer a flexible elongate member to deliver an implantable device to a desired site. An implantable device deployment system may include a slider selectively slidable with respect to the control handle to deploy an implantable device, and optionally to retain the implantable device in a delivery position. A tether adjustment system may include a knob rotatable about the handle's longitudinal axis to axially pull on a tether element to adjust the tension and/or length thereof. A tensioning and locking system may include a knob rotatable about the handle's longitudinal axis to shift a tensioning and locking device to set the tether element's tension and/or length.

Abstract: A flexible elongate member with the ability to deliver a material through a medium-delivery channel defined within a wall thereof. The flexible elongate member may have a tubular wall defining a lumen therethrough, the medium-delivery channel being formed within the tubular wall. The flexible elongate member may be a reinforced flexible tubular elongate member with a reinforcing layer within the tubular wall thereof. One or more filaments forming the reinforcing layer may be hollow to define the medium-delivery channel extending through the reinforced flexible tubular elongate member.

Abstract: A delivery/deployment system for delivering an implantable device within an implantable device housing and for deploying the implantable device from the implantable device housing. A stylet may be used to longitudinally advance or retract the implantable device with respect to the implantable device housing, such as to extend and deploy the implantable device from the implantable device housing. The delivery/deployment system has an implantable-device-extension-limiter arrangement configured to limit the distance which the implantable device may be extended from the implantable device housing. The delivery/deployment system optionally also has an implantable-device-rotation-limiter arrangement configured to limit rotation of the implantable device with respect to the implantable device housing.

Abstract: A steerable device and system allowing a steerable elongate member positioned within another steerable tubular elongate member to be steered independently of the steerable tubular elongate member. The steerable tubular elongate member may be steered in a first plane, bending the steerable elongate member therein in the first plane as well. A steering mechanism operatively associated with the steerable elongate member has a distal portion operatively associated with a steerable region of the steerable elongate member to steer such steerable region within a second plane transverse to the first plane. The steering mechanism is independently movable with respect to a portion of the steerable elongate member proximal to the steerable region so as not to affect the orientation of the steerable region to be steered into a second plane transverse to the first plane.
