An implant for occluding a left atrial appendage may include an expandable framework configured to shift between a collapsed configuration and an expanded configuration. The expandable framework includes a proximal hub and a distal hub. A longitudinal axis of the expandable framework extends from the proximal hub to the distal hub. A radiopaque marker may be positioned longitudinally between the proximal hub and the distal hub in the expanded configuration.

Methods, apparatus, and systems to non-invasively determine intra-luminal placement and patency of a vascular access device. Patency and/or placement are estimated indirectly by measuring a physiological parameter which is indicative of proper patency and/or placement of the vascular access device in a patient. The measurement is compared to a reference value or calibration. If the comparison indicates indication of proper patency and/or placement, a signal is generated. The signal can be used in a number of ways. One example is to give a user-perceivable alarm or indication of proper patency and/or placement. Non-limiting examples include activating a light, an audible buzzer, a vibration, readable displayed text or graphics, or some combination of the same. The user can then have an indirect and at least semi-automatic way of estimating proper patency and/or placement of a vascular access device.

Method and device for verification of intra-luminal placement and patency for vascular access devices

Methods, apparatus, and systems to non-invasively determine intra-luminal placement and patency of a vascular access device. In one form, our device itself remains non-invasive, connecting at the vascular access device's hub outside the patient's body. Patency and/or placement are estimated indirectly by measuring a physiological parameter which is indicative of proper patency and/or placement of the vascular access device in a patient. The measurement is compared to a reference value or calibration. If the comparison indicates indication of proper patency and/or placement, a signal is generated. The signal can be used in a number of ways. One example is to give a user-perceivable alarm or indication of proper patency and/or placement. Non-limiting examples include activating a light, an audible buzzer, a vibration, readable displayed text or graphics, or some combination of the same. The user can then have an indirect and at least semi-automatic way of estimating proper patency and/or placement of a vascular access device. In one aspect of the invention, the technique is able to achieve this end by monitoring and detecting changes in the physiological parameter of systemic vascular pressure via pressure measurement in, at, or near the hub or other portion of a vascular access device that has a lumen placed intra-luminally, and then using the results of that monitoring to indirectly transduce conditions or states indicative of either good placement/patency or bad placement/patency of the vascular access device.

A medical device system may include an elongate shaft having a lumen extending from a proximal end to a distal end, a release wire disposed within the lumen of the elongate shaft configured to releasably attach a medical device to the distal end of the elongate shaft, and a securement member releasably coupled to the proximal end of the elongate shaft and fixedly attached to a proximal end of the release wire. A proximal portion of the securement member may be configured to translate proximally away from the proximal end of the elongate shaft upon application of a proximally-directed force to the proximal portion of the securement member and radially inward directed force to the distal portion of the securement member while the elongate shaft is maintained in a fixed position.

A medical device system may include an elongate shaft having a lumen extending from a proximal end to a distal end, a release wire disposed within the lumen of the elongate shaft configured to releasably attach a medical device to the distal end of the elongate shaft, and a securement member fixedly attached to the proximal end of the elongate shaft and to a proximal end of the release wire. A proximal portion of the securement member may be configured to translate proximally away from the proximal end of the elongate shaft upon application of a proximally-directed force to the proximal portion of the securement member while the elongate shaft is maintained in a fixed position, wherein the proximal portion remains connected to the proximal end of the elongate shaft after proximal translation away from the proximal end of the elongate shaft.
