Abstract: In some examples, a catheter flaring device includes a housing and a pin. The housing includes an interior surface defining a cavity configured to receive at least a portion of a catheter having an entry port and engage an exterior surface of the catheter proximate the entry port. The pin is configured to be advanced into the entry port of the catheter to increase a cross-sectional dimension of the entry port. Flaring the entry port may help reduce catching of a medical device on the entry port of the catheter during a medical procedure.

Abstract: In some examples, a device includes a body configured to receive an elongated medical device, and a conductive element configured to contact a touchscreen of a computing device. An amount of contact between the conductive element and the touchscreen varies based on the compressive force applied to the elongated medical device when the elongated medical device is received within the body.

Abstract: In some examples, a catheter may include an elongate body and a push assembly. The elongate body may include an inner liner defining an entry port into a lumen defined by the elongate body, and an outer jacket. The push assembly may an anchor member positioned at a distal end of an elongate member. Distal to a proximal end of the elongate body, a first portion of the push assembly, comprising the anchor member, may be positioned between a portion of the inner liner and a portion of the outer jacket. The anchor member may extend only partially around an outer perimeter of the inner liner when the catheter is assembled. Proximal to the proximal end of the elongate body, a second portion of the push assembly, proximal to the first portion, may be positioned outside of the outer jacket and the inner liner.

Abstract: In some examples, a catheter may include an elongate body and a push assembly. The elongate body may include an inner liner defining an entry port into a lumen, and an outer jacket. The push assembly may an elongate member extending from a proximal portion to a distal portion, where a cross-section of the distal portion is D-shaped and tapers in a distal direction. Distal to a proximal end of the elongate body, a first portion of the elongate member may be positioned between a portion of the inner liner and a portion of the outer jacket, and proximal to the proximal end of the elongate body, a second portion of the elongate member may be positioned outside of the outer jacket and the inner liner.

Abstract: A catheter may include an elongate body extending from a proximal end to a distal end and defining a lumen; a push member mechanically coupled to the proximal end of the elongate body; and a slidable push grip disposed about an outer perimeter of the push member. The slidable push grip is controllably engageable with the push member. When the slidable push grip is in an engaged state with the push member, the slidable push grip transmits an axial force to the push member to enable the push member to transmit the axial force to the elongate body. When the slidable push grip is in a disengaged state with the push member, the slidable push grip is movable axially in at least one direction along a length of the push member while transmitting substantially no axial force to the push member.

Abstract: In some examples, a medical device includes an elongated body having an elongated body proximal end and a hub attached to the elongated body proximal end. The hub is configured to provide a removable attachment to an object, such as a surgical drape within a sterile field boundary. In some examples, the attachment mechanism comprises a resiliently biased first elongate arm and second elongate arm configured to establish a clamping action on the object and/or configured to establish a snap fit with each other while the objection is positioned between the first and second elongate arms. In some examples, the attachment mechanism may comprise a surface of the hub configured to provide a traction force on the object to hold the hub in place relative to the object.

Abstract: A delivery system for an implantable medical device includes a tool and a tethering member extending side-by-side within an inner shaft thereof; the tool extends within a first lumen, being in sliding engagement therein, and includes a distal end coupling feature that protrudes from a distal end of the inner shaft; and the tethering member has a first segment extending within a second lumen, and a second segment extending from the first segment and distally from the distal end of the inner shaft to an end of the tethering member, which is configured to engage with a holding member of the device, and with which the coupling feature of the tool is configured to couple. A retainer may be joined to another end of the tethering member that protrudes from a proximal port of the system.
