A method and device are disclosed for retrieving embolic coils used for treating an aneurysm of a patient. The method comprises the steps of providing a wire device that is pushable through a microcatheter and has a flexible distal portion comprising distal collapsible arms with a latch member carried by one of the arms. The microcatheter is introduced into a patient's vessel leading to the aneurysm. The wire device, distal end first, is introduced into the microcatheter whereby the arms collapse while they are within the microcatheter. The distal end of the wire device is pushed through the microcatheter whereby the arms open when they extend out of the distal end of the microcatheter. The latch member is manipulated so that it engages an embolic coil to be retrieved. The latch-engaged embolic coil and wire device are withdrawn through the catheter, whereby the arms become collapsed as the arm is withdrawn through the catheter, securing the latch and the embolic coil.

A catheter or catheter sheath introducer, for insertion into a vessel of a patient. The catheter has a rigid housing at its proximal end. The housing has an annular valve for access to the lumen of catheter. The catheter further includes a flexible tube for insertion into the patient. Lastly, the catheter has a resilient transition member intermediate and separating the housing and the tube. The member has a greater flexibility than the tube such that if the catheter is bent, after it is inserted into the patient, it will bend along the transition member where there is no substantial reduction of the cross-sectional area of the lumen adjacent the bend.

A medical apparatus for placing an embolic coil at a preselected position within a vessel comprising a coil assembly having an embolic coil attached to a cylindrical headpiece having at least one bending point formed by a circumferential groove and a deployment catheter having a distal section for retaining the coil assembly such that, when the deployment catheter is pressurized with a fluid the distal section of the catheter expands radially to release the coil assembly at the preselected position.

An elastic, biodegradable plug has a proximal retainer and a distal retainer coupled by a waist. The plug may be positioned to straddle a wound in a blood vessel wall of a patient and therefore close the wound to stop bleeding through the wound. To position the plug in the wound, an operator may insert the plug into a sleeve extending through the vessel wall into the vessel and move the plug through the sleeve with a positioning tool. In the sleeve, the distal and proximal retainers of the plug are compressed. As the distal retainer of the plug exits the distal end of the sleeve into the vessel, the distal retainer expands in the vessel such that a surface of the distal retainer faces an inner side of the vessel wall. The positioning tool and the sleeve are then removed to position the waist in the wound of the vessel wall and allow the proximal retainer to expand such that a surface of the proximal retainer faces an outer side of the vessel wall.
