Abstract
Through observation it has been determined that deployment of delivery sleeves may result in one or more portions of the deliver), sleeve extending beyond an end of the endoluminal device resulting in an overhang of material. The overhang may affect blood flow through the endoprosthesis or otherwise impact performance, including facilitating unwanted tissue growth. Various inventive concepts are provided for addressing (reducing or removing) constraining sheath overhang.
Claims20
A delivery system comprising:
- a delivery sleeve releasably secured in a tubular shape configured to constrain a medical device in a delivery configuration, the delivery sleeve having a length, an upstream edge, a downstream edge, a mid-region between the upstream edge and the downstream edge, a first margin extending along the length of the delivery sleeve, a second margin extending along the length of the delivery sleeve, and a first corner region proximate the upstream edge;
- a first deployment line section releasably coupling the first and second margins of the delivery sleeve such that the delivery sleeve is releasably secured in a tubular shape;
- and;
- a second deployment line section anchored to the first corner region and routed from the first corner region to a first anchor point at the m id-region, the second deployment line section being configured so that upon actuation of the second deployment line section at least a portion of the upstream edge is translated toward the mid-region.
A delivery system comprising:
- a delivery sleeve configured to constrain a medical device in a delivery configuration, the delivery sleeve having a length, an upstream edge, a downstream edge, a mid-region, and a first corner region;
- a first deployment line section extending along the length of the delivery sleeve from the downstream edge to the upstream edge to releasably couple the delivery sleeve in a tubular configuration;
- a second deployment line section extending from the first deployment line section, the second deployment line section coupled to the first corner region and routed from the first corner region to the mid-region and anchored at the mid-region at a first anchor point.
A method for actuating a delivery sleeve of delivery system, the method comprising:
- positioning the delivery sleeve at a desired location, the delivery sleeve forming part of a delivery system including, a medical device with which the delivery sleeve is associated, the delivery sleeve having an upstream edge, a downstream edge, a mid-region, and at least one corner;
- a first deployment line section attached to the delivery sleeve;
- and a second deployment line section attached to the at least one corner and routed through the mid-region;
- applying tension to the first deployment line section such that the first deployment line section actuates the delivery sleeve to effectuate delivery of the medical device;
- and
- applying tension to the second deployment line section such that the second deployment line section translates the at least one corner back toward the mid-region.
A method for delivering a medical device, the method comprising:
- positioning a delivery system at a desired location in a body of a patient, the delivery system including a delivery sleeve associated with a medical device, the delivery sleeve having an upstream edge, a downstream edge, a mid-region, and at least one corner;
- an auxiliary sleeve positioned around the medical device and the delivery sleeve, the auxiliary sleeve having an upstream edge;
- a deployment line including a first deployment line section coupled to the first delivery sleeve and a second deployment line section coupled to the auxiliary sleeve, attached to the at least one corner of the delivery sleeve, and routed through the mid-region of the delivery sleeve;
- releasing the auxiliary sleeve from about the medical device and the delivery sleeve;
- applying tension to the first deployment line section to release the delivery sleeve;
- and
- applying tension to the second deployment line section to translate the upstream edges of each of the delivery sleeve and the auxiliary delivery sleeve toward the mid-region of the delivery sleeve.
