Abstract: A balloon guide catheter having a sleeved inflation lumen secured with a wire wrap for improved inflation lumen kink protection and a welded balloon construction provides a robust and flexible catheter with an exceptionally large inner lumen relative to its outer profile and enables rapid and reliable balloon inflation and deflation in a highly deliverable and kink resistant catheter. Balloon guide catheters having multiple sleeved inflation lumens and proximal luers for utilizing the multiple inflation lumens are also provided.

Abstract: A system has an outer catheter and an inner aspirating clot retrieval catheter having an expansile distal tip for flow restriction, improved aspiration efficiency, and a large mouth into which a clot or other obstructions can be retrieved. The clot retrieval catheter can have a support tube proximal of the tip. The expansile tip can be a strut framework, and a flexible, low-modulus cover is disposed around at least a portion of the tip strut framework and the proximal support tube. The distal end of the tip can be encapsulated by a low-friction elastomeric lip for atraumatic contact with the walls of a blood vessel. The tip has a collapsed delivery configuration and expands radially into a deployed configuration. The tip strut framework, support tube, and cover can all have characteristics which enhance the deliverability of the clot retrieval catheter to the target.

Abstract: A balloon guide catheter including a catheter shaft having a main lumen defined therein extending axially therethrough to receive a guidewire therein and an inflation lumen defined axially therein arranged semi-encircling the main lumen. The inflation lumen having an inlet port radially outward from the catheter shaft and an exhaust vent(s) disposed proximate the distal end of the catheter shaft. The exhaust vent(s) being disposed longitudinally through a distal terminating end of the inflation lumen or radially inward in fluid communication with the main lumen. A porous membrane is disposed at the exhaust vent(s) to permit only gas to pass therethrough. Secured about the outer surface proximate the distal end of the catheter shaft and coinciding with the inlet port is a balloon.

Abstract: A punch and die set include a die with a single large cavity which can receive dry particles of relatively large dimensions or large arching indexes as compared to the transverse dimensions of the tablets formed by the particles, e.g., 1.5 mm diameter and 1 mm height. The upper and lower punches are configured to form an array of interconnected tablets. The punch and dies compress the particles in the die cavity into the array. The tablets are interconnected by an array of links formed by tangential regions of adjacent cylindrical tablets or by links or bridges of finite length, width and thickness dimensions as defined by the punch configurations. The tablets of the arrays are separated by forces created by vibratory or tumbling action. Various embodiments of different shaped tablets and mating punch and die sets are disclosed.

Abstract: The improved fishing device including a first jaw. The first jaw has a first upper portion with a projection, a first lower portion with a projection and a first intermediate with a projection and a hooking portion. Included is a second jaw. The second jaw has a second upper portion with a projection, a second lower portion with a fork projection having apertures therethrough and a second intermediate with a hooking portion. The second upper portion is capable of coupling with the first upper portion. The second lower portion has a bore within. Also included is a swing-arm with a front end being positioned within the second jaw and a rear end coupled to the first jaw. A rubber band for attaching to each hooking portion is provided. Included is a clamp coupled to the first lower portion of the first jaw. A lever with a bolt attached that is capable of having a fishing line is placed thereon. Lastly, a cam is positioned within the fork and has a rod capable of moving the swing-arm.
