Abstract: Golf club heads are releasably engaged with shafts so they may be readily interchanged and/or so that the shaft orientation with respect to the club head can be readily changed. Assemblies for connecting the club head and shaft may include a shaft adapter and a head adapter. The shaft adapter may have an exterior surface extending along a first axis and a bore having a cross-sectional shape along a second axis configured to attach to a shaft member. The second end of the shaft adapter has a cross-sectional shape of a regular polygon. The head adapter has a first end and a second end along a first axis and a bore having a shape of a regular polygon along a second axis that is shaped to receive the second end of the shaft adapter in a plurality of orientations.

Abstract: Golf club heads are releasably engaged with shafts so that the club heads and shafts can be readily interchanged and/or so that the shaft position with respect to the club head can be readily changed. Assemblies for connecting the club head and shaft may include: (a) a shaft engaging member including a rotation-inhibiting structure; (b) a club head engaging member including a shaft-receiving chamber and a retaining structure for engaging the rotation-inhibiting structure; and (c) a securing system for releasably securing the shaft engaging member with respect to the club head engaging member. The club head and shaft may be changed by releasing the securing system and exchanging the original parts with different parts. Furthermore, the shaft may be bent or otherwise extend at an angle from the shaft engaging member so as to allow adjustment of the shaft position with respect to the club head.

Abstract: Golf club heads are releasably engaged with shafts so that the club heads and shafts can be readily interchanged and/or so that the shaft position with respect to the club head can be readily changed. Golf clubs are provided that have spherical releasable connections between the golf club head and the golf club shaft along with head/shaft position adjusting features to allow interchange of shafts and heads and to allow modification of the head/shaft positioning properties. Assemblies for connecting the club head and shaft may include: a shaft adapter, a shaft retainer, and a hosel insert located within an interior chamber of the club head. The club head and shaft may be changed by releasing the securing system and exchanging the original parts with different parts. Furthermore, the shaft adapter may be rotated within the hosel insert to create different angles from the shaft so as to allow adjustment of the shaft position with respect to the club head.

Abstract: A biopsy device such as a core sampling biopsy device compatible with use in a Magnetic Resonance Imaging (MRI) environment by being driven by either a pneumatic rotary motor or a piezoelectric drive motor is disclosed. The core sampling biopsy device obtains a tissue sample, such as a breast tissue biopsy sample, for diagnostic or therapeutic purposes. The biopsy device may include an outer cannula having a distal piercing tip, a cutter lumen, a side tissue port communicating with the cutter lumen, and at least one fluid passageway disposed distally of the side tissue port. The inner cutter may be advanced in the cutter lumen past the side tissue port to sever a tissue sample.

Abstract: Golf club fitting systems and methods include: (a) receiving input data indicating a golfer's driver loft angle and shaft flexibility characteristic; (b) determining initial candidate fairway wood clubs based on this data; and (c) identifying the initial candidate fairway wood clubs. Such systems and methods further may include: (d) receiving launch monitor data generated when the golfer hits balls using the initial candidate fairway wood clubs; (e) determining and identifying additional candidate fairway wood clubs for testing; (f) receiving launch monitor data generated when the golfer hits balls using the additional candidate fairway wood clubs; and (g) determining and identifying a recommendation for a final first fairway wood club based on the data. Other clubs in the fitted set also may be determined by these fitting systems and methods.

The inner cutter may be advanced in the cutter lumen past the side tissue port to sever a tissue sample. A cutter drive assembly maintains a fixed gear ratio relationship between a cutter rotation speed and translation speed of the inner cutter regardless of the density of the tissue encountered to yield consistent sample size.
