The present invention pertains to a stiffened balloon which can be used in angioplasty, endovascular, and valvuloplasty procedures or as a delivery balloon to deliver a stent or a stent-graft. Longitudinally discontinuous stiffening members connected to the expandable balloon stiffen the balloon but allow it to be navigated through curved passages. Projections on the stiffening members may engage, incise, crush, fracture, or pierce occlusions or retain a stent or stent-graft. Radio-opaque portions may be referenced to determine orientation. Longitudinally continuous stiffening members bearing projections and connected to the balloon perform in a similar manner.

A stiffened balloon apparatus with increased flexibility is provided for use in the human body. The stiffened balloon apparatus incorporates one or more stiffeners having at least one thinned area to facilitate bending or flexing of the stiffener as the apparatus is navigated through a passage. The thinned area of a stiffening member facilitates navigation of the stiffened balloon apparatus through a curved passage.

A spreading instrument includes instrument fingers which can be spread to partially define a cylindrical passage between the instrument fingers. A rounded groove on the interior surface of each instrument finger is tapered lengthwise, becoming shallower towards the distal end of the finger. When the fingers are spread, the opposing grooves partly define a cylindrical passage adapted to receive a tubular structure.

A balloon having one or more stiffeners is used to configure an expandable device. Methods of configuring and reconfiguring an expandable device with a balloon having a stiffener attached at its perimeter by orienting the stiffener with the expandable device and expanding the balloon to cause the stiffener to exert radial force against the expandable device are provided. Methods of delivering an expandable device carried on a balloon having a stiffener attached are also provided. Reference to radio-opaque portions of the stiffener facilitate orientation of the stiffener with the expandable device.

An ergonomic hand instrument with a finger grip loop and a thumb grip loop also has a forefinger control surface on at least one of the instrument arms. The control surface may include a proximally facing curved wall surface to receive the distal end of the tip of the user's forefinger. Forward and downward pressure can be applied with the forefinger with improved control and stability.

Improved medical filaments for use with dilators to be inserted into a patient, for example into the vascular lumen, are provided, as well as combinations of filaments and dilators. Methods for use of such filaments and filament-dilator combinations are also described. The filament includes a proximal segment and a distal segment. The diameter of the distal segment is greater than the diameter of the proximal segment. The change in diameter is abrupt, providing a discrete step transition at a point along the filament which presents a proximally-facing surface on the distal segment. When the proximal segment of the filament is fully inserted into a dilator having a distal tip adapted for insertion into a patient, the dilator distal tip firmly abuts the proximally-facing end surface of the distal segment. The relative dimensions of the dilator tip and the discrete stepped transition of the filament provides full shielding or over shielding of the dilator tip, thereby facilitating passage of the dilator tip along the tissue track, through the puncture hole and into the orifice.

An instrument for engaging an underlying blood vessel or body structure. The instrument comprises a pair of instrument arms, and an instrument finger extends at an angle from each arm. The distal end of each instrument finger comprises a bottom surface at an angle to the axis of the instrument finger such that it is adapted to rest upon the underlying blood vessel or body structure. In certain embodiments the bottom surfaces are in a plane that is substantially parallel to the plane of the instrument arms.
