摘要:
A delivery catheter includes a constraining sheath coupled to a distal end of the catheter, and a medical device, such as an embolic protection device (EPD) or a stent, constrained by the sheath. A wire may extend proximally from the constraining sheath and be coupled thereto. A proximal pulling force on the wire causes the wire to tear the constraining sheath, thereby releasing the medical device from a constrained configuration to an expanded configuration.
摘要:
A guidewire stop is disclosed which can be positioned and frictionally locked to a bare guidewire at a user-defined location. The guidewire stop can be used to stop and/or lock a medical device, such as an embolic filter, at a treatment site inside a body lumen. The medical device may be attached to the guidewire stop.

摘要:
A syringe cradle for holding a syringe, the syringe cradle comprising a syringe holder at a proximal end for engaging a barrel of a syringe and a rider for pressing on a plunger of the syringe, a cylindrical body for surrounding the syringe, a distal cap for closing a distal end of the cylindrical body, a stepwise advancing mechanism for advancing the rider along the cylindrical body towards the proximal end, and a stopping mechanism to prevent the rider from moving backwards towards the distal end of the cylindrical body.
